Taber

Taber is a TypeScript / Svelte side-panel browser agent. It runs as a Chrome / Edge MV3 extension and can read pages, extract documents and images, navigate tabs, fill ordinary forms, and explain page failures while the user stays in control.

I built the current version from scratch. The product decision is a supervised side-panel workflow: users can see tool calls, pause or stop tasks, and keep credentials and event history local.

The architecture includes WXT entrypoints, a side-panel UI, an offscreen AgentHost, a local IndexedDB event log, provider configuration, and narrow tool boundaries for document extraction, image extraction, navigation, and controlled browser REPL behavior.

The project is open source and has not been published to Chrome Web Store or Edge Add-ons. Public copy only says the basic browser automation tasks are reliable, without using adoption or store metrics.
