> # Feature flag platforms for startups
> 
> Here's who I'd actually name, roughly in the order I'd suggest trying them:
> 
> **1. PostHog** - My default recommendation for most early-stage startups. Feature flags, product analytics, session replay, and A/B testing in one tool, with a free tier of ~1M requests/month. If you're a small team, the fact that you don't need to buy *and wire up* a separate analytics tool is worth more than any individual flag feature. Pay-per-request pricing after the free tier.
> 
> **2. Statsig** - The best pick if experimentation is the point, not just safe rollouts. Free Developer tier (2M events/mo, unlimited flags), Pro at ~$150/mo. Stats engine is genuinely strong for the price. Caveat worth knowing: OpenAI acquired Statsig in mid-2025 for ~$1.1B and it runs as a standalone product - fine today, but it's a dependency on someone else's strategy.
> 
> **3. Unleash** - Best value if you want open source with a real company behind it. Unlimited free self-hosted usage, Cloud pay-as-you-go from ~$75-80/mo including ~53M requests. Good choice when you want to avoid MAU-based billing surprises and you have someone who doesn't mind running infra.
> 
> **4. GrowthBook** - The on
