Agentbox
An inbox for your coding agents: run dozens of Claude Code and Codex sessions at once on the plan you already have.
About Agentbox
Agentbox gives your coding agents an inbox. Run dozens of Claude Code and Codex agents at once and only hear from the ones that need you: each finished agent lands as a row saying what it did and what it needs. It runs in your browser or as a Mac app and drives Claude Code and Codex on your own machine, signed in with your own subscription, with no server, no account and nothing new to pay for.
Can you use your ChatGPT plan in Agentbox?
Yes. Your ChatGPT plan, through Codex. Agentbox's own page says: "Runs in your browser or as a Mac app, on the Claude Code or Codex plan you already have."
