PlugThis
PlugThis is a purpose-built AI tool for generating Chrome extensions. Users describe the desired extension in plain English and PlugThis produces a fully packaged, Manifest V3–compliant extension (manifest.json, content scripts, popup UI, background service worker) together with optional backend code. It targets builders with no extension-specific engineering knowledge—founders, product teams, and non-coders—who want to iterate quickly, ship to the Chrome Web Store, and own the generated source code.
The platform supports real backends via Supabase and AI-enabled extensions by allowing users to plug in their OpenAI, Anthropic, or Gemini keys. Generated output is a ready-to-install .zip or unpacked folder that you can download, inspect, modify, and publish yourself, with no vendor lock-in and full ownership of the source.

Real backends via Supabase
Connect your Supabase account and PlugThis writes server logic, authentication, and database code for extensions that require user login, storage, or backend processing.
