Playwright storageState, one click
Log in once in your browser, export storageState.json, run your E2E suite authenticated. No scripted login flows, no OTP dances. No other cookie manager does this.

Login sessions, delivered.
SessionCourier is the cookie & session manager for developers and QA: edit cookies, capture login state, and move it safely into Playwright, CI pipelines, and your team's staging setup — from an EU operator you can actually trust with credentials.

// 1. Log in once, in your normal browser.
// 2. Export → Playwright storageState.

});$ npx playwright test

From browser tab to CI pipeline.
The free editor covers everything the daily dev/QA workflow needs. Pro adds the infrastructure around it: profiles, encrypted sync, and headless access.
An editor that keeps up
List, search, filter, edit — single cookies or in bulk. Built and performance-tested against 1,000+ cookie jars, because reliability is where the incumbents fall over.
Every format your tools speak
Import and export JSON, Netscape cookies.txt (curl, wget, yt-dlp) and raw header strings.
Inline JWT decoder
Token cookies decode in place — header, payload, expiry — without pasting credentials into some website.
Cookie protect
Pin a cookie read-only and SessionCourier restores it the moment anything overwrites it. Your debugging session survives the app’s own writes.
Profiles, sync & headless CLI
Named session profiles per domain, end-to-end-encrypted sync, and npx sessioncourier pull to fetch a profile in CI — no browser required. Team vaults for shared staging sessions follow.
trust
Session cookies are credentials.
We treat them that way.
Would you paste your production session into a random free extension? Neither would we. Every claim below is verifiable, not marketing.
Identified EU operator
Full imprint, DSA trader verification in the Chrome Web Store, German jurisdiction. This niche has been burned by anonymous operators twice — we put a name on it.
Reproducible build
“Open source” is a claim. A CI job proving the store build is byte-identical to the public repo is evidence. GPL-3.0 client, verifiable by anyone.
Zero-knowledge by architecture
Everything stored is encrypted on your device — Argon2id key derivation, libsodium secretbox. The server only ever sees ciphertext. We can’t read your sessions, by design.
Minimal permissions
cookies, storage, activeTab. Broad host access stays optional and off by default. No ads, no trackers, GDPR-compliant, EU hosting.
pricing
Cheaper than one broken staging login.
The editor and every export format stay free — no export paywall, no ads in a tool that touches your credentials. You pay for the workflow around it.
