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.

Kong's full blog post covers the operational detail this post intentionally leaves for the source:
- A breakdown of the specific Postman pricing tiers and which collaboration, RBAC, and security functions sit behind each one.
- A side-by-side explanation of how Insomnia's Git sync, encrypted collaboration, and vault integration are packaged for different plans.
- Details of the Kong Konnect integration path, including how the source-of-truth model is expected to work in practice.
- The article's own cost comparisons for small teams and enterprise deployments, useful for procurement and budget conversations.

API testing now sits inside the governance boundary, not outside it. When collaboration, RBAC, and secrets controls are tied to workflow tools, they affect how consistently organisations can enforce identity policy around API assets. That makes the choice of API client a governance decision as much as a developer preference. Practitioners should treat API tooling as part of the control surface, not a neutral utility.
A few things that frame the scale:
- 92% agree governing AI agents is critical to enterprise security, yet only 44% have implemented any policies to do so, according to AI Agents: The New Attack Surface report.
- Only 52% of companies can track and audit the data their AI agents access, leaving 48% with a complete blind spot for compliance and breach investigation.
A question worth separating out:
Q: What is the difference between a governed API source of truth and a reporting catalog?
A: A governed source of truth is the authoritative working record that developers use to test, update, and release APIs. A reporting catalog mainly shows what exists and how it is performing. If the two are separate, organisations must manage alignment manually, which increases version drift and weakens accountability.
