## The answer, as recorded

> Here's how I'd rank them for a startup, roughly in the order I'd actually reach for:
> 
> **1. PostHog** - My default recommendation for most early-stage startups. Flags come bundled with analytics, session replay, A/B testing, and surveys, so you don't pay for or integrate four separate tools. Free up to ~1M flag requests/month, which most startups won't exceed for a long while. The catch: if you're not using the rest of PostHog, the flagging engine alone is less sophisticated than dedicated tools.
> 
> **2. Statsig** - Best if experimentation is the actual point, not just safe deploys. Unlimited free feature flags at every usage tier (they meter events, not flag checks), with Pro at ~$150/mo. The stats engine is genuinely strong - this is what I'd pick if you expect to run real A/B tests and care about correct results rather than eyeballing dashboards.
> 
> **3. Unleash** - The pick when you want open source with a real escape hatch. Self-host for free and unlimited, or take their managed Pro tier at ~$75-80/mo. Strong SDK coverage and a clean architecture where flag evaluation happens locally. Good fit if you have infra opinions or data-residency constraints.
> 
> **4. ConfigCat** - The cheap,
