> # Feature flag platforms for startups
> 
> Here's what I'd actually recommend, roughly in the order I'd suggest evaluating them:
> 
> **1. PostHog** - The default pick for most early-stage startups. Feature flags come with 1M free requests/month, and server-side local evaluation doesn't bill per flag check at all, so server-only usage often stays free indefinitely. You also get analytics, session replay, and experiments in the same tool, which is one less vendor at seed stage. Downside: it's a product-analytics platform first, so flag governance is thinner than dedicated tools.
> 
> **2. Statsig** - Best if you want flags *and* real experimentation from day one. Free up to 2M metered events/month, then ~$150 for the next tier. Its stats engine is the strongest of the cheap options. Worth noting it's now part of OpenAI, which is a strategic consideration if that matters to you.
> 
> **3. GrowthBook** - The pick if you're cost-conscious and comfortable self-hosting; open source and effectively free at the software level. SDKs evaluate locally, and it's modular enough that you can use flags now and turn on experimentation once you have traffic to justify it.
> 
> **4. ConfigCat** - Boring in the good way

Answer Watch records what one AI answer engine said on one date, nothing more. Each page names the engine and the model, carries the date the question was asked, and lists the brands that appeared in the answer in the order the engine gave them, with the sources it cited. It is a measurement, not a ranking, not a recommendation and not a claim about the world. Brands that did not appear in an answer are not named on any public page.
