ConfigCat** - my default recommendation for agencies. Unlimited seats on every plan, so adding a freelancer for a six-week engagement costs nothing, and flat predictable pricing means you can bake it into a retainer without surprise overages. Separate \"products\" and configs let you isolate each client cleanly, and there's a self-host/on-prem path if a client demands it. ([configcat.com](https://configcat.com/), [flagsmith.com](https://www.flagsmith.com/compare/configcat-vs-launchdarkly))\n\n**2. Flagsmith** - best handover story. Open source and free to self-host with unlimited users and unlimited environments, so when the engagement ends you can drop the whole thing into the client's infra instead of transferring a subscription. Cloud Start-Up is ~$45/mo with unlimited environments and projects. Note the self-hosted OSS edition is limited to one project - you'd run an instance per client or go Enterprise.
