> # Feature flag platforms for startups
> 
> Here's what I'd actually recommend, roughly in the order I'd suggest you evaluate them:
> 
> **1. PostHog** - My default recommendation for most early-stage startups. Flags are free up to 1M requests/month, and they come bundled with product analytics, session replay, and A/B testing. If you're pre-PMF, you need all of that anyway, and consolidating into one tool beats stitching together four. The flag engine isn't as deep as LaunchDarkly's, but it covers the realistic 90%.
> 
> **2. Statsig** - Pick this if experimentation is core to how you build, not an afterthought. Free tier goes to 1M MTUs with unlimited seats, and the stats engine is genuinely strong (it came out of Facebook's internal tooling culture). Pro jumps to ~$150/mo, so know that cliff is there.
> 
> **3. GrowthBook** - The best choice if you want open source and self-hosting as a real option. MIT-licensed, free self-hosted, free Cloud Starter for up to 3 users, Pro at ~$40/seat/mo. Warehouse-native, so it runs experiments against your own data rather than requiring you to pipe events to a vendor. Good for teams with data-privacy constraints or an existing warehouse.
> 
> **4. Flagsmith** - So
