Questions.

The honest answers, up front.

Do I still pay for Claude, Codex, or DeepSeek?
Yes. Harmonic runs the agent CLIs you already use with your own plans and API keys — it doesn't resell agent access. Your Harmonic license covers the app itself.
What's in the Free plan?
Harmonic is free to use with up to 2 repos and 5 tabs, one agent per chat — no card, no account. Pro unlocks unlimited repos & tabs, switching agents (Claude/Codex/DeepSeek) mid-chat, and the merge train.
Yearly or Lifetime?
Yearly renews each year at $49. Lifetime is a single $79 payment that never renews and includes all future updates — best if you're in it for the long haul.
How do payments work?
Checkout and billing are handled securely by Dodo Payments. We never see or store your card details.
Can I try before paying?
Absolutely — download Harmonic and use the Free plan as long as you like. No card, no account required.
