Quick answer
MuleSoft is an API-led integration platform owned by Salesforce, built for enterprise API programmes and organisations with in-house integration engineering. Celigo is an integration platform built around prebuilt integration apps, strongest in ecommerce and NetSuite-centric estates. ONEiO is managed iPaaS: integration outcomes delivered as a service, without operating a platform.
If you've found this article, you're probably looking for an enterprise-grade integration solution. In this article we compare MuleSoft and Celigo, two of the more popular integration platform as a service (iPaaS) vendors found in the market today.
Key takeaways
- These are not really competing for the same buyer. MuleSoft is bought by enterprises running formal API programmes. Celigo is bought by teams who want a packaged integration working this quarter.
- Celigo's strength is prebuilt integration apps, with a heritage in ecommerce and NetSuite-centric estates where a packaged integration beats building one.
- MuleSoft's strength is governance at scale: API design, policy management, monitoring and a developer portal as one programme, with the deepest Salesforce ecosystem fit.
- Both shipped agent tooling in 2026. Celigo released Ora, a natural-language gateway, plus Agent Builder and an MCP server on 31 March 2026. MuleSoft's Agent Fabric reached general availability in October 2025.
- Managed iPaaS is a third path. ONEiO delivers the same integration outcomes, but ONEiO designs, runs, monitors and maintains the integrations, with SLA-backed outcomes and 24/7 operations.
What is MuleSoft
MuleSoft is a major player in the integration platform as a service (iPaaS) market focused on an API-led integration strategy. Acquired by Salesforce in 2018, MuleSoft is best known for its Anypoint Platform, which offers broad capabilities for API management and integration.
For ITSM professionals, MuleSoft's value lies in its ability to create a cohesive yet flexible integration network via its Anypoint Platform. Working like an enterprise service bus (ESB), Anypoint allows you to design, deploy, and manage APIs and integrations in a unified manner, supporting both SOA (Service-Oriented Architecture) and microservices environments.
In recent years, MuleSoft has expanded its focus into process automation, offering robotic process automation (RPA) and intelligent document processing (IDP) functionality. These areas bring MuleSoft’s service offering closer to broad, intelligent automation platforms like Workato and UiPath but away from an integration service vendor.
What is Celigo
Celigo is a cloud-native iPaaS solution that offers a low-code platform for integrating various SaaS applications, automating business processes, and synchronizing data across cloud and on-premises IT systems.
Founded in 2011, Celigo initially focused on NetSuite integrations but has since expanded its capabilities to cover a wide range of business applications. With over 4,000 customers globally, Celigo provides pre-built integration templates (IntegrationApps), a visual integration builder, and AI-powered assistance for integration development and management.
Celigo is particularly known for its strength in e-commerce, finance, and marketing integrations, catering to small and medium-sized businesses as well as departments within larger enterprises. The company remains privately held and has raised over $78 million in venture capital funding.
MuleSoft vs. Celigo Integration Platform Comparison
Let’s go through how MuleSoft and Celigo compare in five common integration scenarios: API management, data integration, B2B/EDI integration, application integration and system integration.
API Management
MuleSoft's Anypoint Platform is built for API management. It provides an API Designer for creating RAML or OAS specifications, allowing you to define your API contract before implementation. An API Manager lets you set policies and monitor usage, giving you control over your API's behavior and performance. An API Portal offers documentation and interactive testing capabilities. Overall, MuleSoft gives you one of the most comprehensive solutions for managing API integrations.
Celigo's API management solution enables communication between software systems via APIs. It provides tools to design, deploy, monitor, and manage APIs, ensuring secure connectivity across applications. Integrator.io supports REST and SOAP APIs and offers pre-built connectors and templates for quick integration setup, minimizing coding efforts.
Data Integration
MuleSoft approaches data integration through its own DataWeave data language, which allows for complex data manipulations. The AnyPoint platform supports batch processing for handling large volumes of data, and works with various data formats including XML, JSON, and CSV. The platform also has a large number of ETL/ELT features to support data integrations.
Celigo offers data integration through integrator.io, which synchronizes data across systems in real-time or via scheduled batches. It supports databases, cloud applications, and on-premises systems. Users can map, transform, and cleanse data to maintain consistency and accuracy.
B2B/EDI Integration
MuleSoft supports B2B integrations through EDI message parsing and generation capabilities. It includes support for the AS2 protocol, commonly used in B2B communications. In addition, AnyPoint includes Partner Manager features to handle external data integrations and different data standards of partners.
Celigo facilitates B2B/EDI integration through a B2B Manager solution, enabling the exchange of electronic documents between trading partners through standards like X12 and EDIFACT. It provides pre-configured EDI templates for orders, invoices, and shipping notices, streamlining setup and reducing manual entry errors.
Application Integration
MuleSoft supports application integration through Anypoint Connectors for popular SaaS and on-premises applications. For custom applications, it offers a connector SDK. AnyPoint’s Flow Designer provides a visual environment for creating integration flows between different applications.
Celigo has pre-built connectors for SaaS applications like Salesforce, NetSuite, and Shopify through a drag-and-drop interface and automated workflows. In addition, Celigo has an universal connector feature to configure bespoke integrations using HTTP, FTP, JDBC, AS2, GRAPHQL or Webhooks.
System integration
As MuleSoft is owned by Salesforce, you can guarantee that they have deep ERP and CRM system integration capabilities. MuleSoft supports various system integration patterns, including real-time, batch, and event-driven architectures.
Celigo can handle system integrations between ERP systems, CRM platforms, HR systems, and other enterprise applications. The toolkit includes data transformation, error handling, and monitoring features.
What changed for MuleSoft and Celigo in 2026
Celigo launched Ora and Agent Builder on 31 March 2026, its most substantial release in some time.
Ora is a natural-language gateway to the platform. Instead of opening a builder, a user describes what they need and specialised AI agents interpret the business context, design the integration, troubleshoot errors and manage operations, with governance and auditability built in. Agent Builder is a low-code environment for AI-driven automations that reason through tasks and act across systems, paired with a Model Context Protocol server so rule-based logic and adaptive agents run on one platform. Celigo frames the problem it is solving as the specialist bottleneck: too few people who know how to build integrations.
MuleSoft launched Agent Fabric, generally available from October 2025, a control layer for registering, brokering, visualising and governing AI agents built on any platform.
What this means for the evaluation. The two vendors have picked different problems again, which is consistent with how they differ generally. Celigo is attacking the shortage of people who can build integrations. MuleSoft is attacking the sprawl of agents once they exist.
Celigo's framing of the specialist bottleneck is worth sitting with, because it is accurate. Most organisations do not have enough people who can build and maintain integrations. Making building easier is one answer to that. Not having to build or maintain them at all is another.

ONEiO gives you a streamlined, no-code integration service that stands out for several reasons:
Effortless integrations as a service
While MuleSoft and Celigo have some low- and no-code functionality, ONEiO is the first integration platform that offers end-to-end integrations as a service. This is especially valuable in case you don’t plan to hire a full team of system integrators to maintain your integration ecosystem.
Integration automation beyond pre-built connectors
ONEiO supports a wide range of endpoint types and data formats, including JSON, XML, CSV, and plain text. It provides robust mechanisms for both push (using webhooks and REST/SOAP) and pull (via API, SFTP, SQL) data processing. This flexibility ensures that ONEiO can handle various integration scenarios with ease.
Security and compliance
ONEiO offers strong security features, including encrypted credentials and support for multiple authentication standards (Basic Authentication, Token, API Key, OAuth, etc.). It also allows connections to internal networks and supports reverse proxies or whitelisting. The platform is built on AWS and ensures high availability and GDPR compliance
Business logic and data orchestration
ONEiO provides a no-code editor for creating business logic, transforming, and translating data. It supports various transformation options like regular expressions, case transformations, and date formatting. The platform’s rule robot automates rule creation based on common use cases, making it easy to adjust or add new rules without disrupting existing integrations.

When to choose ONEiO?
ONEiO is especially well suited for seamless ITSM integration across internal and externally managed IT services. It offers a turnkey solution for the complex integration needs of both global enterprises and IT service providers.
ONEiO highlights:
- ONEAi artificial intelligence model trained specifically for IT service integration.
- Faster time-to-value. Typical integrations take 2 weeks from idea to production.
- 100% satisfaction guarantee based on proven enterprise-grade integration service.
When ONEiO is not the right fit
- You have a mature in-house integration engineering team and want maximum platform control. Buy the platform.
- Your estate is ecommerce or NetSuite-centric and a packaged integration app covers the use case. Celigo will be faster and cheaper.
- You are running a formal API programme with published, externally consumed APIs. That is MuleSoft's design centre.
- You want to build and govern your own AI agent estate. Both vendors now sell that. ONEiO does not.
- You have exactly two systems to connect, once, and they will not change. A point-to-point build is cheaper.
What changes when integration is a service rather than a platform
ONEiO is a managed integration service, sometimes described as managed iPaaS. It delivers the same outcomes an iPaaS delivers, which is any-to-any connectivity, lifecycle management and cloud-native delivery, with one structural difference: ONEiO designs, runs, monitors and maintains the integrations, with SLA-backed outcomes and 24/7 operations. Customers decide how much control they keep.
Choose ONEiO when: you want integration outcomes without staffing an integration team. Choose MuleSoft or Celigo when you have mature in-house integration engineering and want maximum platform control.
One integration connects multiple endpoints. No point-to-point custom work for each new connection. Customer systems stay as they are and keep evolving independently.
"Onboard new customers or vendors in weeks, not months." — Paula, Telia
Continuity is somebody's job. Microservices spread across geographic sectors with load balancing. Persistent queuing so data is not lost when a system on either end goes down. AI-powered monitoring 24/7/365. Upgrades, migrations and partner-side changes handled without breaking flows.
"ONEiO doesn't make nightmares for CTO." — Dmitri, Espoo
Outcomes are committed, not attempted. Integration specialists own security and compliance for the integrations themselves, not just for the platform underneath them. Issues are caught and resolved before they reach the business.
"That's what allowed me personally to deliver the solution that was not realistically evaluated to be delivered within such a short term." — Ivan, Hexagon
Who does the work comparison
Bottom line on MuleSoft vs Celigo
These two rarely end up on the same shortlist, and when they do it usually means the requirement has not been pinned down yet. MuleSoft is an enterprise API programme. Celigo is a packaged integration you can have running this quarter. Those are different purchases.
Celigo named the real problem this year when it talked about the specialist bottleneck. Most organisations do not have enough people who can build and maintain integrations, and that shortage is what actually limits how fast the business can move.
Easier building is one answer. Not building or maintaining at all is another. Which one fits depends on whether your team wants to own the integration layer, or wants it to work.
