Why a Lifetime Deal?
We're an early-stage open-core company. LTD supporters help us grow while we build.
In return, you lock in today's pricing forever. When Pro's price rises, your deal stays.
You also get to shape the product — LTD holders get direct access to the founder.

Common questions
About the Lifetime Deal
Do I need to bring my own AI model?
Yes — Lifetime is BYOM-only. Connect your OpenAI, Anthropic, or Google API key to power your sessions. You pay your provider directly for AI inference; everything on Harmonica — sessions, participants, orchestration, synthesis, and cross-pollination — is unlimited and included.
Is usage really unlimited?
Yes. Because you bring your own AI key, you pay your provider directly for inference — Harmonica doesn't meter your sessions or participants. The only limit is your own API plan.
How is this different from Pro?
Same features. The difference is how you pay: Pro is $49/month recurring, Lifetime is $499 once. You break even in about 10 months. Both get cross-pollination, chain workflows, HARMONICA.md, public sharing, managed bots, and unlimited data retention.
Can I get a refund?
Yes. 30-day money-back guarantee, no questions asked.
Will this deal always be available?
No. This is early supporter pricing — it helps fund development while we grow. The price will go up or the offer will close. The $499 price won't last.
