Stop Wasting Time on Repetitive Tasks
Every minute spent switching accounts, clearing storage, or debugging tokens is a minute not spent building features.
The Old Way: Slow & Frustrating
- • Log out → Clear cookies → Log back in (2-3 min each time)
- • Open incognito tabs → Lose all your work context
- • Copy-paste JWTs to external encoders/decoders
- • Navigate through DevTools for every storage check
- • Repeat 20+ times per day = 40-60 minutes wasted
With ELSM: Instant & Effortless
- ✓ Switch profiles in 1 click (5 seconds)
- ✓ All storage types in one clean interface
- ✓ Encode & decode JWTs instantly without leaving the page
- ✓ Save & restore complete user states
- ✓ Save 10+ hours every week for actual development
Premium Features That Pay for Themselves
Each feature is designed to eliminate hours of repetitive work. If you test with multiple user roles, these tools will save you 10+ hours every single week.
Multi-Profile Switching
Testing as admin, user, and guest? Save complete browser states (localStorage, sessionStorage, cookies) for each role. Switch between them in 1 click instead of logging out and back in 20+ times per day.
Built-in JWT Encoder/Decoder
Stop copy-pasting tokens to jwt.io. Encode new JWTs, decode and inspect existing payloads, check expiration times, and validate signatures directly in the extension. See claims, roles, and permissions at a glance.
Enterprise-Grade Security
Your saved profiles and synced data are encrypted with AES-256 before storage. Only you can decrypt them. We never see your tokens, passwords, or sensitive data. Zero-knowledge architecture.
