The short version

  • Each has a real cost: Flowise enterprise tier requires custom pricing with no published rates; 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.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Flowise

  • Enterprise tier requires custom pricing with no published rates

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.

Answered from the vendors’ own pages

Flowise: Does Flowise have a free tier?

Yes, Flowise offers a free plan with 2 flows and assistants, 100 predictions per month, 5 MB storage, and community support.

Source
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.

Flowise: What is Flowise's Starter plan pricing?

The Starter plan costs $35 per month (first month free) and includes unlimited flows and assistants, 10,000 predictions per month, and 1 GB storage.

Source
Nango: 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.

Flowise: How does Flowise charge for additional users?

Additional users on the Pro plan cost $15 per user per month. The Pro plan supports 5+ users with this per-user add-on pricing.

Source
Nango: 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.
