Postman vs SuperTest

From $14 per user/month (Basic, billed annually)

Free and open source

Free tier is generous for individuals. Costs come from collaborator seats and monitoring/mock-call volume, and enterprise plans jump sharply.

Free and open source. You pay in engineering time and CI minutes.

Free plan for individuals and small teams with limited collection runs, mock calls and monitors.

• Near-universal adoption — collections are a lingua franca between teams and vendors.
• Covers design, mocking, testing, documentation and monitoring in one place.
• Newman makes any collection runnable in CI without rewriting it.

• Fast: no network, no separate server process, no port conflicts in CI.
• Tiny API you can learn in ten minutes.
• Works with whichever runner you already use.

• Cloud-first sync raised real concerns for teams handling sensitive API credentials; the offline story has been repeatedly reduced.
• Collections stored in the vendor cloud rather than your repo make code review and branching awkward.
• The desktop app has grown heavy, and per-seat costs add up on large teams.

• Node.js only, and only for services you host yourself.
• In-process testing skips the real network stack, proxies and load balancer.
• No environment management or collection concept for cross-service flows.

Teams that want one tool covering the whole API lifecycle and value ecosystem ubiquity.

Node.js API projects testing their own routes in the unit/integration layer.
