📌 Why is this tool awesome?

I'm the author. It's a local web UI (npx agent-workbench) around the coding-agent CLIs people already have installed: Claude Code, Codex, OpenCode and Antigravity CLI.

Instead of driving the agents through an SDK, it runs the vendor's unmodified CLI inside a pseudo-terminal, so the real terminal is still there and the login stays inside the CLI. The app never reads credentials, has no telemetry and makes no network calls.

On top of that it adds tabs that survive a browser reload, one browsable history for all four CLIs grouped by project, conversations rendered as cards, "Continue with…" to hand a conversation over to a different CLI, full-text search across saved conversations, a context meter and a read-only git panel.

MIT, free, no paid tier. Windows-first; CI installs and starts the package on Windows, Linux and macOS.
