1DevTool puts 9 dev tools — browser, API client, DB, terminal & more — in one window. Your AI agent sees exactly what you see: browser errors, API logs, DB queries. No copy-pasting context. Send logs directly to AI terminals. Orchestrate multiple agents via chat with @mentions. Terminals backed by tmux — persistent across sessions. Running 3 projects at once? Each gets its own terminal, browser tab, and AI agent — all in one persistent workspace. No lost context when switching projects.
