The full review
What is Postman?
Postman is an API platform that gives developers a single place to send requests, inspect responses, and manage the specifications, tests, and documentation surrounding an interface. The vendor describes it as a unified platform for designing, testing, distributing, documenting, and monitoring APIs, and the homepage now leads with AI-native positioning built around an AI Engineer that takes on building, testing, and maintaining APIs across an organisation.
The everyday reality is more grounded. A developer opens the API Client, points it at an endpoint, and reads a formatted response in seconds. What keeps teams inside the tool afterwards is everything layered on top: collections that group related calls, workspaces that share them, and a governance layer that stops credentials leaking somewhere public.
Every protocol in a single client
The API Client remains the centre of gravity. Postman handles HTTP, GraphQL, gRPC, WebSocket, and MQTT from one interface, which removes the usual scramble for a separate desktop app whenever a service uses something other than REST. Authentication is configured from a dropdown rather than manually crafting headers, tokens, or refresh flows.
Scriptable workflows extend the client into automation. JavaScript runs before and after each request, so you can chain calls, pass a token from one response into the next, and assert on the result. Prompt-driven debugging inspects a request and its response, writes assertions, and suggests fixes.
Design, mocking, and generated SDKs
Spec Hub holds multiple API definition formats, including multi-file definitions, so the contract lives beside the requests rather than in a forgotten repository. Mock Servers simulate an API before anyone builds it, which lets frontend work start while backend endpoints are still theoretical. The SDK Generator produces client libraries from a spec, and Flows offers a visual canvas for stitching several calls into a working sequence without glue code.
Testing that runs without a human
Collection Runner executes a whole collection in order, and the Postman CLI carries the same runs into a CI pipeline, so the tests a developer wrote by hand become the ones blocking a bad merge. Monitors validate performance with multi-region support, static IP allowlisting, and a monitor summary dashboard, so latency or failures surface before a customer finds them. Webhook Testing asserts on every event, and the Postman Console is there for debugging when a response makes no sense.
Collaboration and API distribution
Workspaces come in internal, partner, multi-partner, and public varieties, which maps neatly onto how API access actually works: private for the team, shared for a named integration partner, open for public documentation. Inline comments, version control, and activity feeds keep review inside the platform. For distribution, the Run in Postman button drops a working collection into someone else's workspace, and the Public API Network gives external developers a searchable front door.
Governance and the plan ladder
Security tooling matters once more than a handful of people share credentials. Postman Vault provides encrypted secret management, Secret Scanner detects exposed credentials in definitions and collections, and Enterprise adds audit logs and compliance reporting plus advanced role-based access control, which Team offers only in a basic form. The API Catalog and Insights, both Enterprise features, answer which APIs exist and which endpoints anyone is calling.
The ladder runs Free, Solo, Team, and Enterprise. Free is a genuine single-user tier with modest monitoring and integration limits; Solo raises them and adds private NPM packages plus custom domains; Team unlocks unlimited seats and SDK generation; Enterprise layers on governance and the Private API Network. AI credits run 50 a month on Free, 400 on Solo, 400 per user on Team, and 800 per user pooled on Enterprise.
Who should choose Postman
Postman fits any team where several people touch the same APIs and nobody wants to maintain a folder of curl commands. Backend engineers, QA, and integration partners get a shared surface, and the Enterprise governance tooling earns its keep for organisations tracking hundreds of internal services. It is less compelling for a solo developer who pokes an endpoint occasionally, since a lightweight client handles that fine and the collaboration strengths go unused. Strictly code-first teams, whose specs and tests already live in the repository, may also find the platform heavier than they need.
Strengths
- Most widely adopted API client with a huge feature set and ecosystem
- Generous free tier for solo developers with mock servers now unlimited
- Strong team collaboration, RBAC, and governance at Team/Enterprise tiers
- Cross-platform desktop apps (Windows, macOS, Linux) plus a web version
Watch out for
- March 2026 change removed free team collaboration; 2+ users now require paid Team plan
- Per-user pricing adds up fast for larger teams ($19-$49/user/mo)
- AI credits are capped and pooled, limiting heavy AI-native workflows
- Electron desktop app is resource-heavy compared to lightweight rivals

How Postman compares
| Alternative | How it differs |
|---|
| Insomnia | Lighter-weight open-core API client from Kong; simpler UI, popular free tier. |
| Apidog | All-in-one Postman alternative combining design, testing, and mocking, often cheaper per seat. |

Frequently asked questions
Is Postman free?
Yes. Postman offers a free plan for a single user with 10,000 API calls per month, 50 AI credits, the core API client, mock servers, specs, and native Git. No credit card is required. However, since March 2026, free team collaboration was removed, so two or more users now need a paid Team plan starting at $19/user/month.
How much does Postman cost?
Postman's paid plans start at $9/user/month for Solo, $19/user/month for Team, and $49/user/month for Enterprise, all billed annually. Monthly billing runs slightly higher. The former Basic (~$14) and Professional (~$29) plans were discontinued for new customers in March 2026, with Basic users migrating to the Team plan over time.
Did Postman change its pricing in 2026?
Yes. In March 2026 Postman restructured its plans into Free, Solo ($9), Team ($19), and Enterprise ($49 per user/month). The biggest change removed free multi-user collaboration, so teams of 2+ now require the paid Team plan. Mock servers became unlimited on all plans, and custom domains are included on Solo, Team, and Enterprise.
Is Postman still free for teams?
No. As of March 2026, Postman removed free team collaboration. The free plan is now limited to a single user. Any team of two or more people must move to the paid Team plan at $19/user/month (billed annually), which adds shared workspaces, basic RBAC, SDK generation, and 1 million API calls per month.
Postman vs Insomnia: which is better?
Postman is the market leader with the broadest feature set, collaboration, governance, and AI tooling, but it is heavier and pricier per seat. Insomnia (by Kong) is lighter, open-core, and appeals to developers wanting a simpler, cheaper client. Teams needing enterprise governance pick Postman; solo devs and minimalists often prefer Insomnia, Bruno, or Apidog.
