API testing tools and the governance gap teams are missing

TL;DR: Recent Postman pricing changes turn collaboration, RBAC, and security into paid add-ons, while Insomnia keeps Git sync, encrypted collaboration, and enterprise controls bundled into core plans, according to Kong. The practical issue is not tooling preference but how API governance, secrets handling, and developer workflows get monetised in ways that can weaken standardisation.

NHIMG editorial — based on content published by Kong: Evaluating API Testing Tools: Insomnia vs Postman

By the numbers:

• On March 1st, 2026, Postman discontinued free collaboration for small teams.
• For a 3-person team, that means $57 per month just to keep API definitions versioned alongside code.
• For a 10-person team, Postman's enterprise plus security setup totals $780 per month.

Questions worth separating out

Q: How should teams keep API collaboration under governance without slowing developers down?

A: Use a workflow where versioning, review, and shared access happen inside the same tool that developers already use for testing and debugging.

Q: When do API testing tools become an access management issue?

A: They become an access management issue when the tool controls who can see, edit, or publish API definitions, secrets, and environment data.

Q: What do security teams get wrong about API catalogs and visibility layers?

A: They often assume inventory visibility equals operational control.

Practitioner guidance

• Map API tooling to governance controls Inventory where collaboration, RBAC, secrets handling, and domain controls actually live in the developer workflow, then compare that map to your identity and access policy requirements.
• Test for source-of-truth drift Run a simple control test: identify how many manual exports or duplicate specs are needed before a developer can work from the authoritative API record.
• Review pricing against control baselines Evaluate whether essential governance capabilities such as role management, secrets visibility, and encrypted collaboration are bundled into the standard plan or deferred to premium packaging.
