Block the web
you don't want to see.

ESystem is a cross-browser content blocker for NSFW, adult, and 18+ pages and domains. It scans every page you visit and redirects anything it finds to a clean block page — with no data sent anywhere until you sign in and connect your own backend.

Scans in real time

URL, metadata, and page text are checked on every navigation and every DOM mutation. New findings go to your personal blocklist.

Synced across devices

Up to 6 API keys per account. Use one on your laptop, one on your phone, one in a VM — they all share the same blocklist.

You own the data

Stored in Supabase Postgres under your account. Export, delete, or self-host any time. No tracking, no ads, no analytics.

Currently supports Chrome, Brave, and Firefox (MV3). More browsers on request.
