## The answer, as recorded

Asked on 2026-10-10 through Claude (Anthropic) with web search (model claude-opus-5).

> Searched current sources. For agency work the constraint that matters isn't flag features - it's that you run many small client codebases, projects start and end, devs rotate, and at some point you may have to hand the account to the client. That rules out most per-seat and per-MAU pricing. Here's how I'd rank them:
> 
> **1. Flagsmith** - My default recommendation for agencies. Unlimited projects and environments, BSD-3 licensed, and the self-hosted edition has no published request ceiling, so you can run one instance across every client with per-project RBAC and hand off a client's project (or a whole instance) cleanly at the end of an engagement. Free cloud tier runs to ~50k requests/month if you don't want to host. ([costbench](https://www.costbench.com/software/feature-flags/flagsmith/), [PostHog's OSS roundup](https://posthog.com/blog/best-open-source-feature-flag-tools))
> 
> **2. FeatBit** - The best pure-pricing fit if you want managed hosting. Every plan, including the free one, includes unlimited projects and environments; Pro is $49/mo for 10k MAU, Growth $149/mo for 40k. That's the rare vendor whose pricing model doesn't punish you for having 15 clients instead of one product.
