iPaaS Software Options 2026

The volume and variety of application integration inside most UK enterprises has grown well beyond what point-to-point custom code can manage. Every SaaS platform added to the technology estate creates new connections that need building, monitoring, and maintaining. Every cloud migration creates a hybrid environment where on-premises systems still need to talk to cloud services. And every AI initiative - whether that is a chatbot, an analytics model, or an autonomous agent - depends on clean, connected, governed data flowing reliably between systems. Integration platform as a service has moved from a technical plumbing decision to a strategic one.

This post covers the leading iPaaS platforms available to organisations in 2026, structured across enterprise and mid-market tiers. The market includes long-established data integration specialists, major cloud platform vendors offering integration as part of a broader suite, and a newer generation of automation-first platforms that are blurring the boundary between iPaaS and business process orchestration. Viewpoint Analysis is a Technology Matchmaker, helping enterprise and mid-market buyers find and select the right technology fast - aiming to be the place buyers go to understand the software market before speaking to vendors.

One structural development shapes this guide more than any other: Salesforce completed its acquisition of Informatica in November 2025, bringing together the world's most widely deployed CRM platform and the enterprise data management and integration platform trusted by more than 5,000 organisations globally, including over 80 of the Fortune 100. That combination has changed the strategic calculation for any organisation already running Salesforce - and raises important questions for existing Informatica customers evaluating their long-term roadmap.

What is iPaaS Software?

Integration platform as a service (iPaaS) is a cloud-delivered platform that enables organisations to connect applications, data sources, and services - both on-premises and in the cloud - without building and maintaining bespoke point-to-point integrations for each connection. At its core, an iPaaS platform provides pre-built connectors to common enterprise applications, data mapping and transformation tools, workflow orchestration, API lifecycle management, and an operational layer for monitoring what is flowing between systems and catching failures before they cause downstream problems.

The business case for iPaaS investment has shifted materially over the last two years. It used to be primarily about reducing the cost and fragility of custom integration code. In 2026 the conversation is increasingly about AI readiness. AI agents and AI-powered analytics require clean, connected, governed data to function reliably - and the organisations best placed to deploy AI at scale are those that have already invested in a coherent integration architecture. Fragmented, poorly monitored integrations are not just a technical inconvenience; they are a direct constraint on AI ambitions.

iPaaS sits within the broader Data Technology and Transformation Technology landscape. For more context on how integration fits into wider technology investment priorities, visit the Data Technology and Transformation Technology pages on the Viewpoint Analysis website.

How to Find iPaaS Software in the UK

The iPaaS market looks deceptively similar across vendors at the surface level - most platforms advertise connectors, data mapping, API management, and workflow capabilities. The meaningful differences emerge when you examine technical architecture, the depth of integration with specific platforms already in your estate, the balance between developer-grade power and citizen-integrator accessibility, governance and monitoring maturity, and what the total cost actually looks like when integration volumes grow.

The fastest way to cut through the market is the Longlist Builder at Viewpoint Analysis. Powered by HUEY, the Viewpoint Analysis AI Technology Analysis Agent, it generates a tailored list of iPaaS vendors matched to your organisation size, existing technology stack, integration complexity, and specific use cases - in minutes, with no registration required.

If you would prefer the leading iPaaS vendors to present directly to you, the Technology Matchmaker Service takes a different approach. Viewpoint Analysis interviews your team, writes a Challenge Brief that captures your integration landscape and requirements, and invites shortlisted vendors to pitch to you directly - so you hear from the platforms best matched to your situation rather than the ones with the most aggressive sales motion.

Enterprise iPaaS Software Options 2026

Informatica (from Salesforce) Informatica is the most widely deployed enterprise data integration and management platform in the world, with over 5,000 customers in nearly 100 countries and more than 80 of the Fortune 100 relying on it to run their data estates. That depth of enterprise deployment reflects three decades of product investment: Informatica has been building data integration, quality, governance, and master data management capabilities since 1993, and its Intelligent Data Management Cloud (IDMC) now brings all of those capabilities together in a unified, cloud-native platform powered by the CLAIRE AI engine. IDMC has been ranked number one by IDC across five data integration and intelligence software market share categories, a reflection of both its breadth and the scale at which enterprise customers actually use it. In November 2025, Salesforce completed its $8 billion acquisition of Informatica, bringing the platform into the Salesforce portfolio as the data and integration foundation for the Agentforce AI platform. Salesforce has stated clearly that Informatica will continue to support multi-cloud and non-Salesforce environments as a core product commitment - a position that matters to the large share of Informatica's customer base that runs SAP, Oracle, or Microsoft as their primary platform.

Our Viewpoint: The benchmark enterprise data integration and management platform for organisations running complex, multi-cloud data estates - and the strongest starting point for any enterprise where data quality, governance, and integration scale are board-level concerns rather than purely technical ones. For Salesforce customers in particular, the combination of IDMC and Agentforce now offers a single vendor for CRM, AI, and trusted data.

MuleSoft (Salesforce) MuleSoft's Anypoint Platform is the gold standard for API-led integration at enterprise scale, built on the principle that every integration should be designed as a reusable, managed API product rather than a point-to-point connection. The platform was acquired by Salesforce in 2018 for $6.5 billion - at the time Salesforce's largest acquisition - reflecting the strategic importance of integration to the broader Salesforce platform strategy. Anypoint covers API design, development, deployment, and management alongside full iPaaS capabilities including data transformation via the DataWeave language, event-driven integration, EDI, B2B messaging, and hybrid on-premises and cloud deployment. MuleSoft is particularly strong for organisations that want to build and manage a formal API programme - treating integration as a reusable asset library rather than a collection of one-off connections. The platform is developer-heavy by design and carries a premium price point that makes it a better fit for organisations with dedicated integration architecture teams than for those looking to distribute integration development across the business.

Our Viewpoint: The right choice for large enterprises that want to treat integration as a managed API programme and have the development capability to work with a technically demanding but highly capable platform - particularly those with Salesforce at the centre of their technology stack.

Boomi Boomi pioneered cloud-native iPaaS in the early 2000s and has been continuously developing the platform ever since, accumulating a customer base of over 20,000 organisations worldwide - one of the largest in the category. Originally part of Dell Technologies before its separation in 2021, Boomi now operates independently and has continued to invest heavily in its AtomSphere platform, completing five strategic acquisitions in recent years to broaden its capabilities in API management, workflow automation, and AI-assisted integration development. The platform covers application integration, data synchronisation, API management, EDI and B2B management, and business process automation, with a low-code visual interface that makes it accessible to both developer and non-developer users. Boomi's breadth of pre-built connectors and its track record of fast, reliable deployments across complex enterprise environments are consistently cited by customers as primary reasons for selection. Its publicly disclosed service level agreement - guaranteeing 99.99% uptime with financial credits up to 100% for breaches - is one of the strongest commitments in the market.

Our Viewpoint: A strong choice for organisations that need broad, proven connectivity across a large and diverse application portfolio, with a track record of delivery and a platform accessible enough to involve both IT and business teams in building and managing integrations.

IBM webMethods IBM webMethods Hybrid Integration is the result of IBM's 2024 acquisition of Software AG's webMethods integration portfolio, bringing together IBM's existing integration capabilities with one of the longest-established integration platform brands in enterprise technology. webMethods has been serving large enterprise integration requirements since the late 1990s, and its installed base in regulated industries - financial services, insurance, manufacturing, and government - reflects the depth of its B2B, EDI, and complex enterprise messaging capabilities. IBM has since built its Hybrid Integration vision around a single control plane for all integration patterns: application integration, API management, event streaming, B2B, and data integration, with AI services layered across the platform for adaptive automation. For organisations with complex hybrid estates that include mainframe, legacy middleware, and modern cloud systems, IBM webMethods offers connectivity depth that cloud-native platforms find difficult to match.

Our Viewpoint: Worth serious consideration for large enterprises with complex hybrid integration environments - particularly those in regulated industries or with significant legacy and mainframe infrastructure - where the breadth of integration pattern support and depth of B2B and EDI capability are decisive factors.

Microsoft Azure Integration Services Microsoft Azure Integration Services is a family of services within the Azure platform - Logic Apps for workflow and application integration, API Management for API governance and publishing, Service Bus for enterprise messaging, Event Grid for event-driven architecture, and Azure Data Factory for data movement and transformation. Together they cover the full integration stack for organisations whose technology estate is anchored in Azure, Dynamics 365, and the Microsoft cloud. The integration cost advantage for committed Microsoft shops is real: these services can be absorbed into existing Azure enterprise agreements, and the native connectivity with Dynamics 365, Power Platform, and Microsoft 365 removes a significant layer of integration complexity. The trade-off is architectural: Azure Integration Services is a collection of services requiring deliberate design to work together rather than a single unified platform, and its citizen integrator experience is weaker than purpose-built iPaaS tools. SAP and Oracle connectivity requires additional configuration work.

Our Viewpoint: The logical integration choice for organisations deeply committed to the Microsoft stack - particularly those running Dynamics 365 as their core ERP or CRM - where absorbing integration costs into existing Azure agreements and maintaining tight platform cohesion are the primary evaluation criteria.

SAP Integration Suite SAP Integration Suite is the integration platform embedded within SAP Business Technology Platform (SAP BTP), providing SAP's enterprise customer base with a native integration capability that covers application integration, API management, event-driven architecture, B2B messaging, and process integration in a single cloud offering. SAP has been building enterprise integration technology since the early days of its NetWeaver middleware platform, and the Integration Suite represents the cloud-era evolution of that long heritage. For organisations running SAP S/4HANA or SAP ERP, the platform provides a library of pre-built integration content for common SAP-to-SAP and SAP-to-third-party scenarios, significantly reducing the development effort for integrating core SAP processes with adjacent systems. SAP describes the Integration Suite as the integration standard for organisations seeking to standardise on a single technology across their SAP and non-SAP landscapes. The platform's primary limitation is that it is a weaker proposition for organisations without a significant SAP footprint, where the integration content library advantage largely disappears.

Our Viewpoint: The integration platform of choice for SAP-centric enterprises - particularly those running large S/4HANA programmes - where standardising on a single integration technology within the SAP ecosystem reduces complexity and leverages pre-built content that third-party iPaaS platforms cannot replicate.

Mid-Market iPaaS Software Options 2026

Workato Workato has built a distinct position in the iPaaS market as the platform most associated with business-user-led integration and automation, with over 10,000 customers worldwide across a range of industries. Founded in 2013 by former Informatica executives, the platform uses a recipe-based model that makes integration and workflow automation accessible to operations, IT, RevOps, and finance teams without requiring deep integration development expertise - while still providing the governance, security, and monitoring controls that enterprise IT requires. Workato covers application integration, data integration, API management, and what the company calls enterprise orchestration: connecting AI agents, human workflows, and automated processes in a single platform. Its connector library is particularly strong across modern SaaS platforms - Salesforce, Workday, ServiceNow, NetSuite, Slack, and similar - making it well suited to organisations whose integration needs centre on connecting cloud applications rather than managing complex hybrid or legacy estates.

Our Viewpoint: A well-matched choice for organisations that want to put integration and automation capability directly in the hands of business teams - particularly those running Salesforce, Workday, or ServiceNow at the centre of their operations - where speed of delivery and business-user accessibility matter more than developer-grade platform depth.

SnapLogic SnapLogic is a cloud-native iPaaS platform with a particular emphasis on making integration accessible to non-specialist users through its low-code, pipeline-based visual interface. The platform covers application integration, data integration, API management, and workflow automation, with a library of pre-built connectors - called Snaps - spanning common enterprise applications across CRM, ERP, data warehouses, and SaaS platforms. SnapLogic has invested in AI-assisted integration development through its SnapGPT capability, which allows users to describe integration requirements in plain language and generate pipeline configurations from those descriptions - an approach that reduces the technical barrier for teams without dedicated integration developers. The platform is used across financial services, healthcare, retail, and manufacturing, and its self-service design makes it a practical option for organisations that want to distribute integration development beyond a central IT function.

Our Viewpoint: A practical option for organisations looking to accelerate integration delivery by enabling business and IT teams to collaborate on building pipelines - particularly where the volume of SaaS-to-SaaS integrations is high and developer resource is a constraint.

Celigo Celigo is a cloud-first iPaaS platform with a strong reputation in mid-market and growth-stage enterprise organisations, particularly those running NetSuite as their core ERP. Its Integration App model - pre-built, fully managed integration templates for common application pairings such as NetSuite to Salesforce, NetSuite to Shopify, NetSuite to Workday, and similar - significantly reduces the time and expertise required to deliver standard integrations, making it a practical choice for businesses that want fast, reliable connectivity between their core cloud applications without building from scratch. Celigo's platform also supports custom integration development for more complex or less common requirements, and its governance and monitoring tools have matured considerably as the vendor has moved upmarket. It is less well suited to organisations with heavy on-premises infrastructure or complex hybrid integration requirements, where purpose-built enterprise platforms carry a significant capability advantage.

Our Viewpoint: A strong fit for mid-market organisations running NetSuite alongside a portfolio of SaaS applications, where the pre-built Integration App library delivers fast time-to-value on the most common integration scenarios without requiring a dedicated integration developer team.

Jitterbit Jitterbit is a mid-market iPaaS platform with a track record in connecting ERP systems - SAP, Oracle, Microsoft Dynamics, NetSuite - with adjacent cloud and on-premises applications, and a particular strength in B2B and EDI integration scenarios. The Harmony platform covers application integration, data transformation, API management, and low-code workflow automation, with a visual interface that balances accessibility with genuine capability for complex transformations. Jitterbit has positioned itself around speed of implementation as a differentiator, and its professional services capability and partner network are frequently cited positively by customers in evaluations. It sits below the volume and complexity ceiling of enterprise-grade platforms but above the out-of-the-box SaaS focus of Celigo, making it a practical choice for mid-market organisations with diverse application landscapes that include a mix of ERP, legacy, and modern cloud systems.

Our Viewpoint: Worth evaluating for mid-market organisations with complex ERP integration requirements and B2B or EDI scenarios that need more integration depth than entry-level tools provide, without the cost and implementation overhead of enterprise-grade platforms.

How to Select iPaaS Software

iPaaS selection is more consequential than most software decisions because the platform you choose becomes the connective tissue of your entire technology estate. Integration platforms accumulate hundreds of dependencies over time, and replacing one is rarely a simple migration - it is a rebuild. The decision deserves more rigour than a feature comparison matrix and a shortlist based on name recognition.

Your existing technology stack is the first and most important filter. Organisations running Salesforce as their primary CRM now have a compelling case to evaluate Informatica and MuleSoft together as a combined data and integration foundation within that ecosystem. Microsoft-committed organisations running Dynamics 365 should give Azure Integration Services serious consideration before looking elsewhere. SAP-centric enterprises have the same logic applied by SAP Integration Suite. The integration depth and pre-built content these platform-native tools offer within their own ecosystems is real - but it is not automatically decisive if your integration requirements extend significantly beyond those platforms.

Developer capability versus citizen-integrator accessibility is the second dimension that most iPaaS evaluations underweight. Platforms like MuleSoft are built for developer teams and require genuine technical investment to implement and govern well. Platforms like Workato, SnapLogic, and Celigo are designed to be accessible to business and IT users without deep integration development expertise. Neither model is inherently better - the right answer depends on who will actually be building and maintaining integrations day to day, and whether that is expected to change over the contract period.

Total cost of ownership is consistently the most underweighted factor in iPaaS evaluations. The platform that looks most affordable at the licence level often becomes the most expensive to operate as integration volume grows - particularly those with connection-based or message-volume pricing that scales unpredictably. Require vendors to price a realistic three-year scenario covering expected integration growth, multiple environments, support, and implementation services, not just the entry-level commercial case. And weight monitoring and governance capability alongside integration features: an integration that fails silently and corrupts downstream data is worse than no integration at all.

Summary: The iPaaS Market in 2026

The iPaaS market in 2026 is defined by two converging forces: AI is raising the stakes for data quality and integration governance, and the acquisition activity of recent years has concentrated the top of the market into fewer, larger platforms. The Salesforce-Informatica combination is the most structurally significant development the category has seen in years - it creates a single vendor that covers CRM, AI agents, and enterprise data management, which changes the evaluation calculus meaningfully for any organisation with Salesforce at the centre of its technology estate.

Outside of that development, the established platforms each hold their ground for clear reasons. MuleSoft remains the strongest choice for organisations running a formal API programme at enterprise scale, particularly within the Salesforce ecosystem. Boomi's 20-plus years of cloud-native iPaaS development and customer base of over 20,000 organisations gives it a deployment track record that newer platforms cannot match. IBM webMethods brings together two long-established integration heritages and is the strongest option for regulated industries with complex hybrid and legacy estates. Microsoft and SAP each offer the most compelling integration proposition for organisations already committed to their respective platforms.

For mid-market buyers, the common mistake is buying upmarket into enterprise platforms with implementation complexity and total cost that does not fit the organisation - or buying downmarket into tools that create a ceiling the business hits within two years. Workato, SnapLogic, Celigo, and Jitterbit each represent a different and legitimate path depending on team capability, existing application landscape, and whether integration is being led by a central IT team or distributed across the business.
