The question asked, verbatim: best feature flag platforms for agencies

Brands named, in the order the engine gave

1. Flagsmith recommended
   Flagsmith - My default recommendation for agencies.
2. PostHog mentioned
   (costbench (https://www.costbench.com/software/feature-flags/flagsmith/), PostHog's OSS roundup (https://posthog.com/blog/best-open-source-feature-flag-tools))
3. FeatBit mentioned
   FeatBit - The best pure-pricing fit if you want managed hosting.
4. ConfigCat mentioned
   ConfigCat - Worth a quote for agencies specifically because it's flat-rate with unlimited seats rather than per-developer, which matters when contractors cycle on and off a client project.
5. GrowthBook mentioned
   GrowthBook - Pick this when the client is paying for conversion work, not just safe deploys.
6. Mixpanel mentioned
   Genuinely free self-hosted edition (MIT) with unlimited users, real statistics engine, native PostHog/Mixpanel integration;
7. LaunchDarkly mentioned
   LaunchDarkly - Not for your internal standard, but name it when the client is enterprise and mandates it or already has a contract.
8. Statsig mentioned
   Statsig - If a client engagement is experimentation-led, the 1M events/month free tier and the strongest stats engine in the group make it the cheapest way to run real tests.
9. Unleash mentioned
   One to avoid as an agency standard: Unleash.

The answer, as recorded

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. ([featbit.co/pricing](https://home.featbit.co/pricing)) **3. ConfigCat** - Worth a quote for agencies specifically because it's flat-rate with unlimited seats rather than per-developer, which matters when contractors cycle on and off a client project. Smaller ecosystem than Flagsmith; confirm current tier limits before you commit. ([configcat comparison](https://configcat.com/blog/top-launchdarkly-alternatives/)) **4. GrowthBook** - Pick this when the client is paying for conversion work, not just safe deploys. Genuinely free self-hosted edition (MIT) with unlimited users, real statistics engine, native PostHog/Mixpanel integration; cloud Pro is $40/seat/mo. Flags plus A/B testing in one tool you can justify on the invoice. ([costbench](https://costbench.com/best/best-feature-flag-tools/)) **5. PostHog** - Good for the common agency client who wants analytics, session replay, and flags but won't buy three tools. 1M flag requests/month free, no per-seat charges. The catch for you: the free plan is **1 project** and paid is 6, so it's a per-client deployment rather than one agency-wide instance. ([posthog.com/pricing](https://posthog.com/pricing)) **6. LaunchDarkly** - Not for your internal standard, but name it when the client is enterprise and mandates it or already has a contract. It's still the category leader for governance, approvals, and audit trails across many teams, and the free Developer tier (unlimited seats and flags, 30 SDKs) is now usable for a single client build. Foundation pricing is per service connection plus per-1k client MAU, which gets expensive fast across a portfolio. ([LaunchDarkly permissions](https://launchdarkly.com/blog/advanced-permissions-for-special-use-cases/), [dupple](https://dupple.com/learn/best-feature-flag-tools)) **7. Statsig** - If a client engagement is experimentation-led, the 1M events/month free tier and the strongest stats engine in the group make it the cheapest way to run real tests. Weaker fit as a multi-client flag backbone. ([amplitude comparison](https://www.amplitude.com/compare/best-feature-flag-tools)) One to avoid as an agency standard: **Unleash**. Great project, but the open-source/free tier caps you at 1 project and 2 environments, and the paid tier is $75/seat/mo with a 5-seat minimum - close to the worst possible shape for an agency roster. ([tech-insider](https://tech-insider.org/?p=18557)) Short version: self-host Flagsmith as your agency-wide instance, use FeatBit if you'd rather not run infrastructure, and let LaunchDarkly be a client-mandated exception you bill through rather than absorb. Prices above are as published now and move around - verify before quoting a client.
