Here's how I'd rank them with that in mind.\n\n**1. Flagsmith** - My default recommendation for agencies. Open source (self-hostable with no feature restrictions), bootstrapped rather than VC-funded so the pricing is less likely to get repriced out from under you mid-engagement, and it has strong native integrations with analytics providers. The self-host option is the real agency unlock: you can run one instance for your internal/dev work and stand up a separate client-owned instance at handoff, with no per-seat tax for every client's PM who wants to peek at a toggle.

Unleash** - Pick this over Flagsmith when the client is enterprise, privacy-conscious, or high-traffic. Bigger community (~13.4k GitHub stars vs ~6.3k), user data never leaves the client's infrastructur", "answer_truncated": true, "measurement": "One answer from one engine on one date.
