PostHog** - My default suggestion for most startups. Feature flags are free up to ~1M requests/month and come bundled with product analytics, session replay, and A/B testing. At seed stage you need all of those anyway, and consolidating them into one tool (and one bill) matters more than having the best-in-class flag UI. Open source, self-hostable if you ever need it.\n\n**2. Statsig** - Pick this over PostHog if experimentation is the point, not a side benefit. Its stats engine (CUPED, sequential testing, proper guardrail metrics) is genuinely stronger than the bundled-analytics crowd, and flags and experiments live in the same object model so you don't re-plumb anything to go from \"ship behind a flag\" to \"measure the flag.\" Free tier is generous; Pro starts around $150/mo.\n\n**3. GrowthBook** - The best answer if you want to own the infrastructure. Self-host for free with unlimited flags and experiments, and it runs experiments against your existing warehouse (BigQuery/Snowflake/Postgres) rather than making you pipe events to a vendor. Cloud is free up to 3 users. Choose this when you're data-warehouse-first or have compliance reasons t", "answer_truncated": true, "measurement": "One answer from one engine on one date.
