SuperTest vs Postman

Free and open source

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

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

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

Everything, self-hosted

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

• 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.

• 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.

• 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.

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

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