apikumo vs Postman
Testing, docs, mocks, and MCP in one workspace — free for up to 3 members, then $8/seat on Team.
Postman is a broad API platform, and since March 2026 its Free plan is a single user. apikumo covers the everyday core of it — collections, environments, scripts, test suites, mocks, and hosted docs — lets a small team share a workspace for free, and turns every published collection into a read-only MCP endpoint. If you rely on gRPC, MQTT, flows, or performance testing, Postman is still the fuller tool.
Share for free with a small team
A shared org on apikumo Free holds up to 3 members, you included. Postman’s Free plan is limited to one user as of March 2026; its Team plan is $19/user/month billed annually.
Docs, mocks, and tests on one collection
The collection you test is the one you publish: a hosted docs site, schema-based mocks at /mock/<path>, and suites you can run from the CLI in CI.
MCP straight from your published docs
Every published collection is a read-only MCP server. Postman’s MCP Generator builds servers from requests on its public API Network.

- 1Postman docs: “the Free plan is limited to one user and can’t create a team”; it previously allowed up to three users (learning.postman.com/docs/billing/about-plans).
- 2Postman’s MCP Generator creates an MCP server from Postman API Network requests (learning.postman.com/docs/postman-ai/mcp-servers/generate).
- 3Postman pricing: Team $19/user/month billed annually, $23 billed monthly; Solo $9/$12 (postman.com/pricing).

Which one should you pick?
Pick apikumo if…
- You are a team of two or three and do not want to pay per user just to share a collection.
- You want the collection you test to also be your public docs site, your mock server, and an MCP endpoint — without wiring separate tools together.
- You want readers of your docs to get an AI assistant that answers from your live endpoints.
- Your work is REST/HTTP, and you document webhooks and WebSocket endpoints alongside it.
Pick Postman if…
- You need live gRPC, MQTT, or WebSocket clients.
- You use flows or performance testing as part of your release process.
- You want collections synced to Git natively (Postman lists Native Git on its Free plan).
- You work alone and want Postman’s larger Free AI allowance (50 credits a month vs apikumo’s 20).
Moving from Postman
- 1In Postman, export each collection as Collection v2.1 (JSON).
- 2In apikumo, import the file — requests, folders, request auth, and collection variables (as an environment) carry over.
- 3Recreate any separate Postman environments you rely on, then send a few requests to confirm auth and variables resolve.
- 4Group the requests you want to regression-test into a suite, then run it from CI with the CLI (npm i -g @apikumo/apikumo).
- 5Publish the collection for a docs site, schema-based mocks, and a read-only MCP endpoint, and invite up to two teammates on Free.
Where apikumo falls short
- WebSocket support is documentation only today: you can describe a socket’s handshake URL, params, headers, and auth, but not open a live connection and exchange messages.
- No gRPC, MQTT, or Socket.IO clients.
- apikumo runs in the browser and needs a sign-in; there is no offline or local-only mode, and no desktop app yet.
- No flows or performance testing.
