## The answer, as recorded

Asked on 2026-09-26 through Claude (Anthropic) with web search (model claude-opus-5).

> For agency work the ranking looks different than a general "best flags tool" list, because your cost driver isn't MAUs - it's **seats** (rotating contractors + client stakeholders), **number of separate client projects**, and whether you can **hand the account off** when the engagement ends. In that order:
> 
> **1. ConfigCat** - my default recommendation for agencies. Every tier includes unlimited seats, unlimited MAUs, and unlimited flag reads; what you pay for is products/flags/traffic. So adding a client's PM, QA, and three contractors costs nothing. Free: 2 products/10 flags; Pro $110/mo: 3 products; Smart $325/mo: 10 products; Enterprise $900/mo: unlimited products. The "product" boundary maps cleanly onto "one client," and it's plug-and-play rather than a platform you have to own.
> 
> **2. Flagsmith** - the pick when a client insists data stays in their infrastructure, or when you know you'll hand the whole thing over. Open source with self-hosted, private cloud, and SaaS options; cloud free tier is 50k requests/mo, paid from ~$45/mo. You can stand up an instance inside the client's environment and walk away from it at project end.
> 
> **3. Unleash** - same handoff logic, stronger if
