Postman: cost, fit and limits
Postman is an API platform made by Postman, Inc. where teams design, test, mock and document APIs in shared workspaces, with custom-branded documentation, an MCP server and AI agents added to the same product. The Free plan covers one user.
What to know first
Postman has Free at $0 for one user, Solo at $9 a month billed annually, Team at $19 per user a month billed annually, and a contract-priced Enterprise tier. Documentation is one feature among many: custom-branded docs and custom domains start on Solo. The pricing page also shows AI credits with paid overages, and the data policy text was not readable.

Who Postman is best for
Individual developers
Solo costs $9 a month billed annually and adds custom-branded documentation, unlimited custom domains and expanded API monitoring for one user.
Teams already testing in Postman
Specs, mock servers, Native Git and the Collection Runner share a workspace, so docs come from the same collections that tests use, and Team adds role-based access control.
Teams using coding assistants
A Postman MCP Server and a CLI with pre-built agent skills are named, and Claude Code, ChatGPT and Cursor integrations are listed through marketplaces and plugins.

What Postman does
- Custom-branded documentation
- Solo and above publish documentation with custom branding and unlimited custom domains, built from the same collections and specs used for testing. Free does not include it, so the $9 Solo plan is the lowest entry.
- Fern docs and SDK generation
- The Postman page describes Fern docs and SDK generation as generating API docs and SDKs instantly. The pages we read do not give plan limits for it.
- AI agents and MCP
- Agent Mode and AI Engineer are named as AI features, alongside a Postman MCP Server, a CLI with pre-built agent skills and a Context Graph with queries counted per plan.
- Native Git
- Native Git and collection runners support testing and documentation workflows, and Free includes both, so versioned collections need no paid tier. Free allows 1 user, so a shared workspace with viewers needs the $19 Team plan.
- Metered AI credits
- AI overages are unavailable on Free and cost $0.05 per credit on Solo and $0.04 on Team, so heavy agent use changes the monthly bill.
How Postman handles your data
The vendor's policy was not checked for this. The Postman legal page opened without policy text, and the Security section was linked but its content was not read, so training use, retention, hosting region and certifications are unverified. The pricing page does give some usage figures: Free has 25 Automation Flows credits a month and 1,000 API monitoring requests. It also shows two different Free-plan AI credit figures, 100 on the plan card and 50 per month in the table. Ask Postman for its current privacy terms and security documentation.
Where Postman falls short in practice
- Docs are a side feature. Postman centers on building and testing APIs, so reader-facing features such as a reader assistant were not named for the documentation product on the pages we read.
- Inconsistent AI credit figure. The Free plan AI credit count is 100 on the plan card and 50 per month in the table, and overages are unavailable on Free, so confirm it.
- Cloud testing is gated. Cloud performance testing is unavailable on Free and Solo and costs $0.04 per VU-hour on Team and Enterprise. Collection recovery is one day on Free and 30 on Solo.

Alternatives to Postman
Postman: common questions
Which Postman plan includes custom-branded documentation?
Solo, at $9 a month billed annually, lists custom-branded documentation and unlimited custom domains, and Team and Enterprise include them through the Everything in Solo wording. Free covers an API client, specs, mock servers and Native Git for one user.
Does Postman generate SDKs from documentation?
The Postman page lists Fern docs and SDK generation and describes it as generating API docs and SDKs instantly. The pages we read give no plan limits or languages, so ask which plan includes it and how many endpoints it covers.
How much do Postman AI credits cost?
AI overages are unavailable on Free and cost $0.05 per credit on Solo and $0.04 on Team. The pricing page also shows two Free-plan credit figures, 100 on the plan card and 50 per month in the table, so confirm the allowance before relying on it.
Does Postman have an MCP server?
Yes. The product page names a Postman MCP Server and a Postman CLI with pre-built agent skills. It also lists integrations with Claude Code, ChatGPT and Cursor through marketplaces and plugins, though the pages give no tool list or plan limits.
Is Postman a good fit for a public developer portal?
It fits teams that already keep collections in Postman and want branded docs on a custom domain. Teams that want a dedicated portal with a reader assistant should compare ReadMe, Mintlify or Scalar, whose pages name those features directly. That reader-facing gap is the main reason Postman ranks ninth here.
