01 — Anatomy

Everything about a request, one click away.

Pick any request and its full story opens beside the list: what was sent, what came back, and how it compares with every other call to the same route.

  1. Timing in context

    Each request is placed against the p50 and p95 of its own route, so outliers stand out.

  2. Secrets stay masked

    Authorization headers, cookies and tokens are hidden until you choose to reveal them.

  3. Bodies, decoded

    JSON as a tree, forms as fields, gzip and brotli unpacked. Binary is described, not dumped.

  4. Replay it

    Copy any request as cURL or JSON and run it again from your terminal.

  5. Filter like a query

    status:5xx time:>500 method:post and plain text, combined.

02 — Security

Sealed on your server. Opened in your browser.

Requests carry passwords, tokens and customer data, so we never store them in the clear. Your server encrypts each one with your project's public key, and your browser opens it. Signing in unlocks a new browser; turn on advanced protection and only your own devices hold the key, end to end.

03 — Pricing

Free while you build. Ten dollars when you ship.

The same SDK does both: it keeps a dashboard on your machine while you develop, and switches to the cloud when it finds an API key.
