The question asked, verbatim: best feature flag platforms for startups
Brands named, in the order the engine gave
- PostHog recommended
PostHog - My default pick for most early-stage startups.
- per-seat recommended
The free tier is 1M flag requests/month with all features included, and flag pricing is pay-per-request rather than per-seat.
- Statsig recommended
Statsig - The pick if experimentation is the point.
- ConfigCat recommended
ConfigCat - Best boring-and-cheap option.
- Flagsmith recommended
Flagsmith - The open-source middle ground, ~$45/month managed or self-host for free.
- Unleash recommended
Unleash - The other strong open-source choice.
- LaunchDarkly recommended
LaunchDarkly - The market leader and the most capable standalone flag platform: approval workflows, release automation, scheduling, SAML/SCIM, custom roles.
- Foundation recommended
But it's built for scale and priced accordingly - the Foundation tier runs $12/service connection/month plus $10 per 1k client-side MAU, with experimentation billed separately.
- OpenFeature mentioned
One thing worth doing regardless: wrap whichever you choose behind OpenFeature (https://openfeature.dev), the CNCF vendor-neutral SDK standard.
- Amplitude mentioned

The answer, as recorded
# Feature flag platforms for startups 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 analytics, no experimentation; it just does flags reliably. Pick this if you want a flag switch and nothing else. **4. Flagsmith** - The open-source middle ground, ~$45/month managed or self-host for free. Worth it specifically if you have data residency or compliance constraints (healthcare, EU, fintech) that make a US SaaS vendor a problem. **5. Unleash** - The other strong open-source choice. Unlimited free self-hosted usage, managed Pro around $80/month, though their cloud tiers are seat-based ($0-$75/seat). Best if you have infra people who'd rather run it themselves and want a mature, well-architected codebase. **6. LaunchDarkly** - The market leader and the most capable standalone flag platform: approval workflows, release automation, scheduling, SAML/SCIM, custom roles. But it's built for scale and priced accordingly - the Foundation tier runs $12/service connection/month plus $10 per 1k client-side MAU, with experimentation billed separately. For a startup this is usually premature. Revisit it when you have compliance requirements or enough engineers that governance features actually matter. **One thing worth doing regardless:** wrap whichever you choose behind [OpenFeature](https://openfeature.dev), the CNCF vendor-neutral SDK standard. It's a few hours of work and makes switching providers later a config change instead of a migration. DevCycle is OpenFeature-native if you want that built in. **Quick heuristic:** Already using PostHog or want analytics bundled → PostHog. Serious about experiments → Statsig. Just want cheap, simple toggles → ConfigCat. Compliance/self-hosting requirements → Flagsmith or Unleash. Enterprise governance needs → LaunchDarkly.
