SessionCourier — Cookie & Session Manager for Devs

Inspect, edit, and export cookies & sessions — JSON, Netscape, header string, Playwright storageState.

SessionCourier is the cookie and session manager built for developers, QA engineers, and test automation: inspect and edit cookies, capture login state, and move it wherever your workflow needs it — Playwright, CI pipelines, your team's staging setup. Login sessions, delivered. PLAYWRIGHT STORAGESTATE, ONE CLICK Log in once in your normal browser — where SSO, 2FA, and passkeys just work — then export storageState.json and run your E2E suite already authenticated. No scripted login flows, no OTP dances. Session expired mid-pipeline? Re-export in one click. AN EDITOR THAT KEEPS UP List, search, filter, and edit cookies — one at a time or in bulk. Performance-tested against 1,000+ cookie jars, so even the busiest sites stay snappy. EVERY FORMAT YOUR TOOLS SPEAK Import and export JSON, Netscape cookies.txt (curl, wget, yt-dlp), raw header strings — and Playwright storageState. INLINE JWT DECODER Token cookies decode in place — header, payload, expiry — so a production token never ends up in a random online decoder. COOKIE PROTECT Pin a cookie read-only and SessionCourier puts it back the moment anything overwrites it. Your debugging session survives the app's own writes. WHY TRUST A COOKIE MANAGER AT ALL? Cookie managers handle your most sensitive data: live login sessions. SessionCourier is built to be checked, not taken on faith. • Open source — GPL-3.0 on GitHub. The store package is built reproducibly, so you can verify that what you install is what you can read. • Private by default — your cookie data stays in your browser, and nothing is collected behind your back. The only telemetry is strictly opt-in, counts feature usage only (EU-hosted, publicly documented), and never sees cookie contents. • Identified EU operator with a full legal imprint — not an anonymous developer account. • Minimal permissions — site access is requested at runtime, only for what you actually do. No ads, no data resale. COMING NEXT — PRO (WAITLIST OPEN) Named session profiles per domain, end-to-end encrypted sync, and a headless CLI (npx sessioncourier pull) to fetch a profile in CI without a browser. Team vaults for shared staging sessions follow. The free editor stays free — no export paywall.
