Session Stash

Manage and switch multiple account sessions per site. Encrypted cookie and localStorage sync via Cloudflare KV.

Session Stash saves encrypted snapshots of cookies and localStorage so you can switch between multiple accounts on the same website with one click. Perfect for developers, QA, support engineers, and anyone juggling personal + work logins on the same site. ━━ Why Session Stash? ━━ • Switch accounts on GitHub, ChatGPT, Stripe, Linear, Notion, or any site — no incognito windows, no browser profiles, no logging out • End-to-end encrypted with your master password (AES-GCM-256, PBKDF2-SHA256, 600,000 iterations) • Stored in YOUR OWN Cloudflare KV namespace — we never see your data, we don't run any server • Sync across browsers and devices that share the same vault ━━ How it works ━━ 1. Connect your own Cloudflare account — Account ID, Workers KV Namespace ID, and an API token with KV read+write (2-minute setup) 2. Set a master password — used only inside your browser to derive the encryption key; never transmitted 3. On any site, click "Save current" to snapshot the active cookies + localStorage under a label like "work" or "test-account" 4. Click "Switch" to jump between accounts — the tab reloads with the chosen identity ━━ Features ━━ • Toolbar popup quick-switcher for the current site • Full-height sidepanel showing every site you've saved, with search and drill-in navigation • Auto-lock after configurable idle timeout • One-click "Clear" to wipe the current site's session • Push / Pull sync with your Cloudflare KV • Rename, delete, and organize sessions per site • Chrome MV3 architecture — service-worker only, zero persistent background process ━━ Privacy ━━ Session Stash does not collect, transmit, or access your data. All network traffic flows directly from your browser to your own Cloudflare account — ciphertext only. No analytics, no telemetry, no third-party servers.
