> Here's what I'd actually recommend, roughly in the order I'd reach for them:

> **1. PostHog** - My default suggestion for an early-stage startup. Flags, analytics, session replay, A/B tests, and surveys in one tool, with a free tier of about 1M flag requests/month. The real argument isn't price, it's that you can see a flag, its experiment, and replays of the users who hit it in one place - and you probably need analytics anyway, so it's one vendor instead of two.

> 
> **2. Statsig** - The best pick if experimentation is the point, not just toggling. Unlimited free feature flags at any volume (they monetize analytics events, not flag checks), so you don't get punished for traffic growth. Stats engine is genuinely strong - CUPED, sequential testing - which is unusual at this price. Pro is ~$150/mo. ([statsig.com](https://statsig.com/blog/comparing-feature-flag-platform-costs))
> 
> **3. GrowthBook** - Pick this if you want open source and your data already lives in a warehouse. It runs experiments against Snowflake/BigQuery/Databricks/Redshift rather than making you pipe events somewhere new, and SDKs evaluate locally w
