The short version
- Only Nango has a free tier, so it costs nothing to try first.
- Each has a real cost: Nango the licence is Elastic License 2.0, which is source available rather than OSI open source, and it forbids offering Nango to third parties as a managed service, so anyone planning to resell or embed it in a platform for their own customers has a genuine legal problem.; Relevance AI no published standard pricing tiers or plans

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Nango
- The licence is Elastic License 2.0, which is source available rather than OSI open source, and it forbids offering Nango to third parties as a managed service, so anyone planning to resell or embed it in a platform for their own customers has a genuine legal problem.
- Pricing is per connection where a connection is one authorised end-user account, so cost scales linearly with your customer base and a product where each user links several services multiplies quickly beyond what a headline plan price suggests.
- Pre-built integrations vary in depth, and a connection that exists is not the same as a connection that covers the endpoints and objects your feature needs, so each one must be verified before it is designed into a roadmap.
- Custom syncs are written in TypeScript and run in Nango model, which means integration logic lives in a vendor runtime and migrating away later requires rewriting it rather than lifting it out.
- Self-hosting removes the vendor from the data path but transfers operational responsibility for a component that holds customer OAuth tokens, and few teams appreciate the security burden that comes with running that themselves.
Relevance AI
- No published standard pricing tiers or plans
- Pay-per-task model pricing varies significantly by AI model selection
- Enterprise quotes require direct contact with sales

Answered from the vendors’ own pages
Nango: Is Nango open source?
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.
Relevance AI: What is Relevance AI's pricing model?
Relevance AI uses a pay-per-task model where costs vary by AI model selected. Average cost per task is approximately 0.09 USD, with actual costs ranging from 0.01 to 0.11 USD depending on which model the system routes to. The platform automatically selects the lowest-cost model that meets performance requirements.
SourceNango: How is it priced?
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.
Relevance AI: How much do Relevance AI tasks cost?
Task costs depend on model selection. Example usage shows customers spending 11800 USD monthly while processing 1.24 million tasks. For enterprise custom pricing, users must book a demo or contact the sales team.
SourceNango: Can we integrate an API Nango does not support?
Yes. Custom syncs and actions in TypeScript cover any API including internal ones, which is the main advantage over closed unified API products.
Nango: Can we self-host it?
Yes, under the Elastic License 2.0 terms, which permit self-hosting for your own use but not resale as a service.
