> 
> Here's what I'd actually recommend, in order:
> 
> **1. PostHog** - My default pick for most early-stage startups. You get flags, A/B testing, product analytics, session replay, and surveys in one tool, so you're not paying for and wiring up four separate vendors. The free tier is 1M flag requests/month with all features included, and flag pricing is pay-per-request rather than per-seat. If you're pre-product-market-fit and want to see *whether the feature worked*, not just toggle it, this is the one.
> 
> **2. Statsig** - The pick if experimentation is the point. Stats engine is genuinely strong (it came out of Facebook's internal tooling), local evaluation is sub-50ms, and the free tier is generous at ~1M events/month. Choose this over PostHog if you're running real experiments with meaningful traffic and care about statistical rigor; choose PostHog if you want broader product tooling.
> 
> **3. ConfigCat** - Best boring-and-cheap option. Free tier covers 1,000 flags and 10M requests/month, and the paid Shared plan is $25/month with *unlimited team members* - which matters a lot, because seat-based pricing is what kills flag budgets as you hire. No anal
