## The answer, as recorded

Asked on 2026-09-30 through Claude (Anthropic) with web search (model claude-opus-5).

> Searched - here's what I'd actually recommend, ordered for the agency case specifically (many clients, seats churning as contractors rotate on and off, and every build eventually needing to be handed over to the client without a painful migration).
> 
> **1. 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.

> 
> **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.
