The 6 most popular alternatives to Nango.dev in 2025

As you look to build customer-facing integrations at scale, you’ll likely end up evaluating several unified API platforms—including Nango.

To help you assess whether the unified API solution is the best fit for your company’s integration needs, we’ll compare it to leading embedded iPaaS solutions and unified API platforms.

Merge

Merge offers a unified API that lets you add hundreds of integrations to your product across key software categories, including accounting, HRIS, file storage, ticketing, CRM, and ATS.

Top features

• Constantly builds out additional integrations and expands into key software categories. For example, they recently added integrations with Lattice, Coolcare, and FolksHR 

• Provides advanced integration observability features, like fully-searchable logs and automated issue detection, to help your customer-facing teams manage integrations independently and effectively

• Offers advanced features—like Field Mapping and Authenticated Passthrough Request—to help you sync custom fields across your integrations

When to choose Merge over Nango

• You want to adopt a proven solution. Merge has been around a few years longer than Nango and has a more comprehensive track record of supporting enterprise organizations, such as BILL, Ramp, Qualtrics, and Mistral

• You need to support reliable integrations. Nango relies on an open-source community to maintain their integrations, while Merge has a fully-staffed team of engineers who maintain the integrations on your behalf

• You’d like comprehensive go-to-market support. As you launch product integrations, you’ll need to decide how to price, market, and support them. Merge—unlike Nango—has a team of integration experts that can help you navigate each of these areas successfully

Paragon

Paragon provides an embedded integration platform as a service (iPaaS) that lets you build customer-facing integrations and workflow automations.

Top features

• Supports agentic integrations with ActionKit—which offers a Model Context Protocol (MCP) server that lets you access their integrations’ endpoints via tools 

• Offers 20+ categories of API connectors to help you build a wide range of integrations, faster

• Provides an enterprise price plan that supports advanced security and syncing features and functionality, like role-based access control, extended log storage (longer than 90 days), and dynamic field mapping

When to choose Paragon over Nango

• You need integration support beyond Nango’s existing categories. Paragon can support more integrations than Nango (e.g., Magento), many of which can be table stakes for your product

• You want more comprehensive support. You’ll only get adequate onboarding and ongoing support on Nango’s enterprise price plan. Paragon, on the other hand, offers onboarding support, ongoing support via email and Slack, and a dedicated customer success manager on several plans

• You’re looking to test the platform through a relatively simple free trial. Paragon offers a 14-day free trial, and while Nango offers their own trial, theirs requires making meaningful infrastructure investments

Case in point: The CTO of Twine, a product intelligence platform, had this to say about Nango’s “free trial”:

“Nango requires an initial infrastructure investment before you can even start testing it.”

Prismatic

Prismatic offers an embedded iPaaS solution and an integration marketplace product that can help you market your integrations within your product and drive adoption.

Top features

• Offers customizable deployment options. Namely, customers can either use Prismatic’s workflow builder within your product to activate integrations or your customer-facing team can activate the integrations on their behalf

• Supports a highly-customizable integration marketplace product. For example, it lets you decide how users can configure integrations and it gives you the option to use their design and UX elements or incorporate your own 

• Lets you integrate with countless applications faster with pre-built connectors, including AI connectors like Google Gemini and OpenAI

When to choose Prismatic over Nango

• You want to have an integration marketplace on your site. Nango doesn’t provide any support here

• You need best-in-class support throughout your integration journey. All of Prismatic’s pricing plans include real-time chat and email support. Nango doesn’t provide any visibility on this level of support across their plans

• Your customers want more control over their integrations. Prismatic, unlike Nango, lets you decide which customers can implement and fine tune their integrations and workflow automations

Workato

Workato offers a wide range of integration and automation solutions, including an embedded iPaaS.

Top features

• Provides an iPaaS to help IT and business technology teams build internal integrations and automations across lines of business

• Offers Workbot®, a customizable chatbot for Slack or Microsoft Teams, to help users easily kickstart and participate in workflow automations

• Offers a suite of AI features and capabilities to help you build better integrations and automations, faster. For example, their Copilots can help users turn plain text into usable “recipes”, or workflow automations

When to choose Workato over Nango

• You want to use a proven solution. Workato is more than a decade old, and widely-known brands across industries use their embedded product, such as Zendesk, Shutterstock, and Autodesk

• You want hands-on training and support. Workato not only offers a post-sales team that can help you become familiar with the platform, but they also have an academy that lets you and/or your customers become proficient in using their embedded workflow platform

• Your integration needs extend beyond your product. You can also leverage Workato’s other integration offerings—like their iPaaS for internal use cases—to meet other integration requirements. Doing so can also help you earn a discount

Kombo

Kombo is a European-based unified API solution that specializes in HRIS, payroll, and ATS integrations.

Top features

• Lets you white label their solution end to end—including guides for setting up an integration. This can help make it seem as though your team built and maintains the integrations

• Offers searchable logs to help you review specific syncs and troubleshoot issues more easily

• Provides extensive integration support for their categories. For example, they offer more than 70 integrations in HRIS alone

When to choose Kombo over Nango

• You only care about HRIS, payroll, and ATS integrations. Kombo offers more integrations across these categories and they're generally deeper (i.e., they can support more use cases)

• You want to adopt a fast-growing and more promising solution. While both companies were founded in 2022, Kombo is growing much faster. For example, they have roughly 50 employees while Nango is still under 10

• You need to support more integrations that are popular in the EU. Since Kombo was founded in the EU and serves most of its customers in that region, their integration offerings are naturally titled towards European companies' integration needs

Apideck

Apideck offers hundreds of cross-category integrations through its unified API.

Top features

• Provides an integration marketplace solution that supports several kinds of pages. This includes everything from landing pages for individual integrations to a partner requests landing page that captures demand from potential integration partners

• Offers Custom Field Mapping to help you sync custom data across customers’ apps

• Has native and virtualized webhooks that can notify your product of events in customers’ systems in real-time. This, in turn, allows your product to respond quickly and effectively

When to choose Apideck over Nango

• You want an integration partner that offers clear and flexible pricing plans. Unlike Nango, Apideck’s pricing includes explicit price points and details on what each plan entails

• You want a usage-based free trial. Nango’s free trial is only 14 days while Apideck’s isn’t time bound—it’s usage based (you can make up to 2,500 requests for any unified API)

• You’re also looking for an integration marketplace product. Apideck offers a relatively comprehensive solution, while Nango doesn’t offer anything currently

Final thoughts

The best product integration solution for your business ultimately depends on your budget, your integration use cases, and the level of guidance and support you need. 

That said, for nearly every scenario, Merge will be your best option. 

Merge is the leader in the G2 Grid® for Unified APIs, and has several customer stories (e.g., Firstbase) that highlight how it lets you scale and maintain your integrations more easily than embedded iPaaS vendors.
