> # Feature flag platforms for startups
> 
> Here's who I'd actually name, roughly in the order I'd suggest you evaluate them:
> 
> **1. PostHog** - My default recommendation for most early-stage startups. Flags are bundled free with product analytics, session replay, and A/B testing (free tier covers 1M flag requests/month), so you don't end up paying for and integrating two or three separate tools. If you're pre-product-market-fit and want to see *whether the flagged feature actually moved a metric*, this is the shortest path.
> 
> **2. Statsig** - Pick this over PostHog if experimentation is the point rather than a side benefit. Its stats engine is genuinely strong (it came out of Facebook's internal tooling lineage), the free tier is generous, and flags + experiments live in one model. Slightly more analytics-flavored than release-engineering-flavored.
> 
> **3. ConfigCat** - The pragmatic choice if you want *just feature flags*, cheap and boring. Real free tier, transparent self-serve pricing, fast setup, broad SDK coverage. No analytics ambitions, which is a feature if you already have Amplitude or Mixpanel.
> 
> **4. GrowthBook** - The one I'd name for bootstrapped/seed teams who care about cost
