> # 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 suggestion for most startups. Feature flags are bundled with product analytics, session replay, A/B experiments, and surveys, so you get the full loop: ship a flag, see the experiment results, and watch replays of the users who hit it, all in one place. Free up to 1M flag requests/month with no feature gating. If you're pre-Series A and don't already have an analytics stack, this consolidates four tools into one bill.
> 
> **2. Statsig** - Best if experimentation is the real goal and flags are the vehicle. It's the only major platform offering unlimited free feature flags at every usage level - pricing scales on analytics events, not flag checks, so you never get punished for a chatty SDK. Free up to 2M events, Pro from ~$150/month. Strong stats engine; this is what I'd pick if you plan to run real A/B tests rather than just kill switches.
> 
> **3. ConfigCat** - The pragmatic pick if you want *just* flags, cheap and boring. Forever-free plan with all features unlocked, and the Shared plan is ~$25/month with **unlimited team members** -
