Who builds on FunctionFly
Indie founders ship their first agent in an afternoon. Growing startups scale to millions of tool calls a week without a trust-engineering hire. Enterprises get the audit trail and zero-knowledge vault their security team requires. Cloud Agent publishers turn one ffpkg into a paid marketplace listing.
Shipping the first agent
You built an AI feature and now need trustworthy agent tooling without enterprise overhead. FunctionFly gives you 100+ curated functions, a free weekly quota, and a marketplace — without a DevOps team.
Scaling agent + API workloads
Your team is shipping fast and agents are calling more tools every week. You need policy-friendly trust metadata, signed receipts, and execution-backed signals — not a pile of unvetted endpoints and a Zapier bill.
Governance and compliance
Your organization needs auditability, least-privilege access to tools, and consistent trust policies across agents and teams. The vault scopes every secret grant, the trust layer scores every call, and a signed receipt is minted for every action.
Selling through the marketplace
You build AI agents for a living. Publish to the marketplace with one package, get discovered by every FunctionFly customer, and get paid per call. Generous publisher share.
We're at the start of the public-launch chapter. If you're an early customer with a published case study we'd like to feature, please reach out.
Indie founders get free Pro for a quarter. Enterprise design partners get custom SLAs, SSO, and direct engineering access. Everything in between gets a fair plan.
