PlugThis
PlugThis is a product that generates fully working Chrome extensions from plain-English descriptions. It produces Manifest V3–compliant extensions including manifest.json, content scripts, background service workers, a popup UI, and an optional Supabase backend. AI features are built-in and can be powered by user-provided OpenAI, Anthropic, or Gemini API keys. The output is a downloadable .zip containing 100% source code that you own and can publish to the Chrome Web Store.
The product is targeted at builders, founders, and teams who want to ship Chrome extensions quickly without writing boilerplate extension architecture or backend scaffolding. PlugThis emphasizes speed (extensions in minutes), production readiness (real backends, Manifest V3 compliance), and code ownership (no vendor lock-in).
