Brands named, in the order the engine gave

1. PostHog recommended
   PostHog - My default suggestion for most early-stage startups.
2. Statsig recommended
   Statsig - Best pick if experimentation is central to how you ship.
3. ConfigCat recommended
   ConfigCat - The one I'd name if you want just feature flags, done cleanly, with no analytics layer to think about.
4. Flagsmith recommended
   Flagsmith - The best middle ground if you want open source with a real hosted option.
5. per-seat recommended
   No per-seat and no MAU billing, which is the thing that kills you on other platforms as you grow.
6. Unleash recommended
   Unleash - Pick this if self-hosting is the plan from day one.
7. GrowthBook recommended
   GrowthBook - Worth a look if you want open-source and a proper stats engine, and you already have a warehouse.

The answer, as recorded

# Feature flag platforms for startups Here's what I'd actually recommend, roughly in the order I'd suggest trying them: **1. PostHog** - My default suggestion for most early-stage startups. Flags come bundled with product analytics, session replay, experiments, and surveys, so you get one tool instead of four, and you can jump from a flag to the experiment running on it to replays of users who hit it in one place. Generous free tier (first 1M events/month free). The catch: flags are a feature, not the product, so targeting rules are less sophisticated than dedicated tools. **2. Statsig** - Best pick if experimentation is central to how you ship. The free tier is genuinely usable (1M events/month), pricing is transparent usage-based, and there's a startup program. The stats engine is the strongest of the affordable options. Worth noting: Statsig was acquired by OpenAI in 2025, so if long-term vendor independence matters to you, weigh that. **3. ConfigCat** - The one I'd name if you want *just* feature flags, done cleanly, with no analytics layer to think about. Free tier covers 10 flags and 5M config downloads, and unusually it includes SSO/SAML even on free. Flags are evaluated client-side so user data never leaves your infrastructure - nice for privacy-sensitive products. Pro jumps to $120/month, which is the main downside. **4. Flagsmith** - The best middle ground if you want open source with a real hosted option. No per-seat and no MAU billing, which is the thing that kills you on other platforms as you grow. Startup plan around $45/month, and you can self-host the same codebase if you need data residency. **5. Unleash** - Pick this if self-hosting is the plan from day one. The open-source version is genuinely unlimited and mature, with a well-designed architecture (SDKs evaluate locally, so no latency hit). Cloud pricing is per-seat and gets expensive fast, so it's really an "own your infra" choice. **6. GrowthBook** - Worth a look if you want open-source *and* a proper stats engine, and you already have a warehouse. It runs experiments against your existing data rather than ingesting its own events. Free for 3 users; $40/seat/month after. **LaunchDarkly** - I'd name it but mostly to tell you to skip it at your stage. It's the most capable platform in the category and the enterprise default, but the per-MAU model punishes consumer products exactly when they succeed, and it's overkill for a small team. **Short version:** if you have no strong opinion, start with PostHog and get analytics for free. If experimentation rigor is the point, Statsig. If you want flags and nothing else, ConfigCat. If you need to own the data, Flagsmith or Unleash self-hosted.
