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

Brands named, in the order the engine gave

1. per-seat mentioned
   Per-seat pricing is the thing that kills agency economics, so that drives my order.
2. ConfigCat recommended
   ConfigCat - my default recommendation for agencies.
3. Flagsmith mentioned
   Flagsmith - the best pick when you want the self-host option as leverage.
4. LaunchDarkly mentioned
   LaunchDarkly - name it when the client is enterprise and procurement/security review is part of the deal.
5. Unleash mentioned
   Unleash - pick this specifically for self-hosted, data-residency-sensitive clients (health, finance, EU public sector).
6. PostHog mentioned
   PostHog - if you're already putting PostHog in client sites for analytics, use its flags and don't add a vendor.
7. Statsig mentioned
   Statsig or GrowthBook - reach for these when the engagement is actually conversion work and the client wants A/B results, not just release toggles.
8. GrowthBook mentioned

The answer, as recorded

For an agency the ranking is different from a product team's, because your constraints are: lots of small projects, lots of non-dev stakeholders who need view/toggle access, and eventually handing the whole thing to the client. Per-seat pricing is the thing that kills agency economics, so that drives my order. **1. ConfigCat** - my default recommendation for agencies. It doesn't charge per seat: unlimited team members, unlimited MAU, priced only on config JSON downloads. That means you can add every client PM, QA person and account manager without the bill moving, and you can keep separate products/configs per client. Entry paid pricing is roughly $49/mo on the cheaper tier (one source cited $110/mo for Pro, so tiers have shifted - check the live pricing page before quoting a client). It's deliberately simple: toggles and targeting, not an experimentation suite. ([configcat.com](https://configcat.com/blog/configcat-pricing-calculator/), [capterra.com](https://www.capterra.com/p/187099/ConfigCat/)) **2. Flagsmith** - the best pick when you want the self-host option as leverage. It explicitly models multiple organisations, projects and environments, which maps cleanly onto a client roster, and it's open source so you can run it on your own infra or on the client's. Free for one team member with unlimited flags and ~50k requests/mo; cheapest paid plan around $45/mo with unlimited environments and projects for three members. Good middle ground on price and portability. ([flagsmith.com](https://www.flagsmith.com/compare/flagsmith-vs-unleash), [flagsmith.com](https://flagsmith.com/blog/top-7-feature-flag-tools)) **3. LaunchDarkly** - name it when the client is enterprise and procurement/security review is part of the deal. Projects-and-environments structure handles multiple products, it's the most mature platform, and nobody gets fired for choosing it. But it's quote-based with MAU-driven cost (~$12/mo + ~$10 per 1,000 MAU as a rough shape), so it only makes sense on retainers where the client pays for their own account directly - don't absorb this on your own card. ([launchdarkly.com](https://launchdarkly.com/implementation), [dupple.com](https://dupple.com/learn/best-feature-flag-tools)) **4. Unleash** - pick this specifically for self-hosted, data-residency-sensitive clients (health, finance, EU public sector). Open source, flexible rollout strategies, you control the infra. Caveat for you: there's no free cloud tier, and the hosted plans are per-seat starting around $80/mo for five members and only three projects - the opposite of what an agency wants. Self-host it or skip it. ([costbench.com](https://costbench.com/compare/flagsmith-vs-unleash/), [configcat.com](https://configcat.com/blog/top-launchdarkly-alternatives/)) **5. PostHog** - if you're already putting PostHog in client sites for analytics, use its flags and don't add a vendor. Free tier covers ~1M flag requests/mo, which is more than most agency builds will ever touch. Weaker as a pure flag-governance tool, but the consolidation win is real. ([posthog.com](https://posthog.com/blog/best-feature-flag-software-for-developers.md)) **6. Statsig or GrowthBook** - reach for these when the engagement is actually conversion work and the client wants A/B results, not just release toggles. Statsig has a genuinely usable free tier (~2M events) with Pro from ~$150/mo; GrowthBook is free for 3 users, ~$40/seat/mo for Pro, and self-hostable for free. GrowthBook's self-host path is the more agency-friendly of the two. ([dupple.com](https://dupple.com/learn/best-feature-flag-tools), [amplitude.com](https://amplitude.com/compare/best-feature-flag-tools)) One thing worth settling before you pick: decide whether flags live in *your* agency account or in each client's own account. Billing in your account is simpler and cheaper day-to-day, but it makes you a permanent dependency the client has to pay to remove at handoff - and it means a client offboarding is an account migration. If handoff is normal in your business, ConfigCat or self-hosted Flagsmith are the easiest to transfer cleanly.
