Merge: Closed unified API with deeper normalisation across HR, accounting and CRM categories, at higher cost and less flexibility

Open source unified API and OAuth infrastructure for product integrations, licensed under Elastic License 2.0
As of 31 August 2026, Nango has a free plan and paid plans start at $50/month. Nango handles the OAuth, token refresh, rate limiting and sync plumbing behind third-party integrations, with over four hundred pre-built connections and the ability to write your own. Softwr lists it under Automation Integration. Nango is available on Web, Linux, Docker.
Overview
Nango is integration infrastructure for product teams. It manages the parts of a third-party integration that are identical every time and tedious every time: the OAuth dance, credential storage, token refresh, rate limit handling, pagination, retries, webhook receipt and incremental synchronisation. It ships hundreds of pre-built API connections and, unlike closed unified API vendors, lets you write custom syncs and actions in TypeScript for any API, including internal ones, and run the whole thing yourself. The licence is the fact that should change a shortlist. Nango is published under Elastic License 2.0, which is source available rather than open source by the OSI definition. You may read, modify and self-host it, but you may not provide it to third parties as a managed service and you may not circumvent its licence key functionality. For the overwhelming majority of buyers, product teams embedding integrations in their own application, this is irrelevant. For anyone contemplating offering Nango as part of a platform to their own customers, it is disqualifying, and it should be checked with counsel rather than assumed from the word open source on the homepage. Pricing is per connection per month, where a connection is one authorised end-user account: free up to 10 connections, 50 dollars a month from Starter with 20 connections then a dollar per additional connection, 500 a month for Growth with 100 connections, and enterprise quoted. That model is unusually predictable but scales linearly with your customer base, so a product where every user authorises three services costs three times what the connection count intuition suggests.
The honest half
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Nango.
Cross-shopped
Each pairing was judged by two reviewers asking whether a buyer would genuinely weigh the two against each other. The ones that failed were deleted rather than published.

Paragon: Embedded integration platform with a visual builder, better if non-engineers should maintain integrations


Alloy Automation: Embedded iPaaS with a unified API and a stronger workflow layer for customer-facing automation


n8n: Open source workflow automation if the problem is internal automation rather than customer-facing product integrations

Answered, with sources
Each answer names the page it came from, so you can check it rather than take our word for it.
It is source available under Elastic License 2.0. You can read, modify and self-host it, but you cannot offer it to third parties as a managed service. That is not the same as an OSI approved open source licence.
Per connection per month, where a connection is one authorised end-user account. Free to 10 connections, 50 dollars a month for Starter with 20, 500 for Growth with 100, and one dollar per additional connection.
Yes. Custom syncs and actions in TypeScript cover any API including internal ones, which is the main advantage over closed unified API products.
Yes, under the Elastic License 2.0 terms, which permit self-hosting for your own use but not resale as a service.

Softwr does not host reviews and shows no star rating for Nango, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it.
