Built by an engineer.
Run like infrastructure.
feat is a feature-flag platform. Right now it works best for early engineering teams, and it is tuned for them on purpose. That widens as the product grows.
I'm Vishnu Mohanan, the founder, and for now the entire engineering team. The control plane, the edge delivery tier, and the five SDKs are my code, and support@feat.so lands in my inbox.
Today is the operative word. Nothing here is designed around staying small; it's designed so that a flag system your production depends on behaves the same whether one person runs it or thirty do.
Why this exists
Start with the economics. Metered flag platforms punish good architecture: run forty microservices and you pay for forty service connections before a single user shows up, then the per-MAU rate climbs with exactly the growth you wanted. And the complexity is priced in, layers of enterprise machinery you never asked for. feat charges a flat rate. Server connections come out of an allowance we never bill, and the advanced surface stays off until you turn it on.
If you've run feature flags for long enough you know the pattern: price the platform per seat and it becomes engineering's tool, full stop. Rollout state lives in a few heads. Support pastes screenshots into Slack because a login costs money. I wrote up the full argument in why we don't charge per seat; the short version is that the bill tracks our real cost curve, which moves with your end users, not your org chart.
The same instinct shapes the product. Evaluation happens in your runtime, changes stream out in under a second, and every mutation lands in an audit log on every plan. When we haven't shipped something, the pricing page says so with a date on it.
Where we are
Young, and honest about it. v1.0 shipped in May 2026 with the platform, five SDKs, docs, and the legal paperwork a procurement review asks for. Everything is written down on purpose. The wire format is a published schema and the evaluation semantics are documented to the hash, so the next engineer here starts from the docs, not from me. The changelog shows what's landed since, dated. The comparison page says plainly where the incumbent is still ahead.
