Why APIScribe

Everything you need.
Nothing you don't.

Built by a developer, for developers. No bloat, no subscriptions, no cloud.

DevTools Panel

Lives natively inside Chrome DevTools — right where you work. No popup, no separate window.

Full Recording Controls

Start, Pause, Resume, and Stop recording at any time. Pause mid-session without losing captured data.

Configurable Fields

Choose exactly what to capture — timestamps, latency, status codes, request payloads, headers, and response bodies.

Two Export Formats

Export as plain .txt for tooling or .md for documentation. Custom filenames with auto-timestamps.

Privacy First

All processing happens in your browser. No external servers, no analytics, no data ever leaves your machine.

Settings Sync

Preferences are saved via chrome.storage.sync and follow you across Chrome sessions automatically.

Get Started
