> # 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
