session infrastructure for dev · qa · automation
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.
// 3. Point your tests at it:
export default defineConfig({
use: { storageState: 'e2e/.auth/staging.json' },
});$ npx playwright test
✓ 42 passed — no login flow, no OTP, no flakesfeatures
The free editor covers everything the daily dev/QA workflow needs. Pro adds the infrastructure around it: profiles, encrypted sync, and headless access.
Log in once in your normal browser — where SSO, 2FA and passkeys actually work — then export storageState.json and run your E2E suite authenticated. No scripted login flows, no OTP dances; when the session expires mid-pipeline, re-export in one click.
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.
Import and export JSON, Netscape cookies.txt (curl, wget, yt-dlp) and raw header strings.
Token cookies decode in place — header, payload, expiry — without pasting credentials into some website.
Pin a cookie read-only and SessionCourier restores it the moment anything overwrites it. Your debugging session survives the app’s own writes.
Start the recorder, run a login, logout or checkout flow, and watch the diff fill in live: what was added, what was refreshed — before → after, flags and expiry included — what was cleared, plus the transient cookies a before/after snapshot never sees. Captured changes stay in memory and are gone when the browser closes.
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
Would you paste your production session into a random free extension? Neither would we. A competitor can copy any one of these; the bundle — an identified EU operator, a reproducible build, a browser-to-CI session bridge and zero-knowledge storage in one tool — is what they can’t. Every claim below is verifiable, not marketing.
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.
“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.
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.
Five at install: cookies, storage, activeTab, scripting, sidePanel — not one of them shows a host-access warning. Broad host access stays optional and off by default. No ads, no trackers, GDPR-compliant, EU hosting.
