Agents as characters

The main agent leads; each sub-agent gets a nameplate, a job and speech bubbles. Stuck, failed and approval-needed states show up on stage.

📊

Simple, honest numbers

Tokens, context fill and cost per session, a weekly Insights chart and a quota bar for Copilot. No walls of text.

🎭

10 themes

Software office (the default), space station, kitchen, prison, football, sheep farm, sneaky ship, spell academy, galactic fleet and a hillside quest. Add your own with JSON.

🔔

Never miss a prompt

Notifications when an agent needs approval, gets stuck or fails. Open the session's terminal in one click.

🏆

Awards & progression

FAQ

Does it send my code or prompts anywhere?

No. Hubbub only reads local session logs and shows tool names, timestamps and token counts.

Do I need a GitHub token?

Only for the Copilot quota bar (via gh auth login). Everything else works without it.

Which macOS versions are supported?

macOS 14 (Sonoma) or later, on Apple silicon and Intel.

Can I add my own theme or provider?

Yes. See the theme guide and contributing.

Is it affiliated with GitHub, Anthropic, OpenAI…?

No. Hubbub is an independent project. Names and logos belong to their owners.
