The answer, as recorded
# Feature flag platforms for startups Here's who I'd actually name, roughly in the order I'd suggest you evaluate them: **1. PostHog** - My default recommendation for most early-stage startups. Flags are bundled free with product analytics, session replay, and A/B testing (free tier covers 1M flag requests/month), so you don't end up paying for and integrating two or three separate tools. If you're pre-product-market-fit and want to see *whether the flagged feature actually moved a metric*, this is the shortest path. **2. Statsig** - Pick this over PostHog if experimentation is the point rather than a side benefit. Its stats engine is genuinely strong (it came out of Facebook's internal tooling lineage), the free tier is generous, and flags + experiments live in one model. Slightly more analytics-flavored than release-engineering-flavored. **3. ConfigCat** - The pragmatic choice if you want *just feature flags*, cheap and boring. Real free tier, transparent self-serve pricing, fast setup, broad SDK coverage. No analytics ambitions, which is a feature if you already have Amplitude or Mixpanel. **4. GrowthBook** - The one I'd name for bootstrapped/seed teams who care about cost control and data ownership. MIT-licensed, self-hostable, and it runs experiments against your own warehouse rather than shipping event data out. Trade-off is you maintain it. **5. Flagsmith** - Solid open-source alternative with a usable managed tier (free to 50k requests, ~$40/mo startup plan) and an unrestricted BSD-licensed self-hosted edition. Good middle ground between "SaaS convenience" and "we need this inside our VPC" - worth it if you have compliance or data-residency constraints early. **6. Unleash** - Best self-hosted option if your bottleneck is engineering discipline, not analytics. Free-forever self-hosted tier with unlimited flags and all core features; strong on flag lifecycle and cleanup, which matters more than people expect by year two. **7. LaunchDarkly** - The mature, enterprise-grade incumbent: deepest targeting rules, best SDK ecosystem, strongest governance and audit story. I'd name it last for *startups* specifically because the pricing scales hard (~$75/mo at 10k MAU, ~$400/mo at 50k) and most of what you're paying for is enterprise release safety you don't need yet. Great once you're selling to enterprises yourself. **Short version:** if you want one answer and no more deliberation - PostHog if you want flags plus analytics, ConfigCat if you want flags and nothing else, Unleash or GrowthBook if you must self-host. One caveat worth flagging: most of these comparisons (including several sources below) are published by vendors in this exact market, so the rankings are not neutral. The pricing figures are the part worth trusting; the "best" labels, less so.
