Routelint vs ZAP, Burp, and Postman

OWASP ZAP and Burp Suite shine when a security engineer drives a proxy, builds attack lists, and interprets raw traffic. They are powerful and flexible. They also expect time, tooling setup, and often an OpenAPI file or a manually explored site map.

Postman (and similar clients) help you call endpoints you already know. They are not identity-replay suites out of the box: you still design each anonymous and peer request, and you still need a list of routes the vibe-coded UI opened.

Routelint is narrower. You prove a host, a browser session records XHR and fetch, then five fixed suites replay those calls with no session and as a peer. Evidence is redacted and stored on an account. There is no local proxy to install. The tradeoff is scope: it is built for route exposure and IDOR-style checks on apps you own, not a full manual pen test.

Choose ZAP or Burp for deep, operator-led testing. Choose Postman for day-to-day API calls you author. Choose Routelint when the product shipped UI-first, the OpenAPI file is missing or stale, and you want a repeatable hosted check on the handlers the interface already proved exist.
