6 Alternatives to Postman in 2026
Teams move away from Postman when a per-user Team plan at $19 starts to add up, when metered AI credits and Context Graph limits worry them, or when they want collections stored as plain files in Git. The common destinations are Apidog, Insomnia, Bruno and Requestly.
Why people look for an alternative to Postman
Seat cost and plan ladder
Postman Team costs $19 monthly per user on annual billing, and Solo, at $9, serves a single user. Shared workspaces mean paying per seat, and governance belongs to Enterprise, which is quote only.
AI is metered in credits
Solo includes 400 AI credits monthly, Team gives 400 for each user, and Enterprise pools 800. Which plans include Agent Mode is not stated on Postman's pricing page, so budgeting AI use is difficult.
Cloud workspaces versus files
Postman keeps collections in workspaces and offers Native Git, but Free recovers deleted collections for one day and Team for 90. Developers who want everything as files in the repository look at tools built around that.

Before you switch away from Postman
Export your Postman collections, environments and globals first, and check which of them hold secrets before they leave. Note how many monitors, mock servers and Flows you run, since Postman's limits for those (10,000 monitoring requests on Solo and Team) do not carry over, and the new tool may price them differently. Look at your CI scripts, because the Postman CLI commands will need replacement. Run one collection in the candidate and compare the results. Postman states that your data does not train its models and lists AWS hosting in the EU and the U.S., so ask the next vendor for the same in writing.

Frequently asked questions
Does Postman train AI models on my API data?
Postman's security page says your data does not train its models, with no further detail, and that data and backups sit on AWS servers in the EU and the U.S. Of the alternatives, Insomnia's AI relies in part on third-party providers, while Bruno's and Requestly's vendor policies were not checked for this.
Can I import Postman collections into an alternative?
Testfully advertises Easy Switch for Postman and Insomnia imports, and Requestly positions itself for teams leaving Postman. Import support for the other tools was not checked for this page, so test an export with your largest collection and confirm that scripts, variables and environments survive before you move a team.
Which Postman alternative is cheapest for a small team?
Bruno's Open Source edition costs $0 and Pro is $6 per user monthly on annual billing. Next come Apidog from $9, Requestly Team at $10 and Insomnia Pro at $12, against $19 for Postman Team. Several free tiers cover only one or two people, so check the limits.
What does Postman have that alternatives lack?
Postman lists an API Catalog, Private API Network, governance, audit logs and a Postman MCP Server on its higher plans, plus a Passport credential proxy for agents. Most alternatives are narrower clients. Enterprise-scale governance is the main reason larger teams stay, while smaller teams often need only the client and tests.
