> 
> Here's what I'd actually reach for, roughly in order:
> 
> **1. PostHog** - The default recommendation for most startups. Flags come bundled with product analytics, session replay, A/B testing, and surveys, so you can see a flag, the experiment on it, and replays of users who hit it in one place. Generous free tier (1M events/month), open-source and self-hostable. The catch: flags are a feature of a bigger platform, not the main event, so flag-specific governance is thinner than LaunchDarkly's.
> 
> **2. Unleash** - Best pick if you want real open source with no vendor lock-in. Unlimited free self-hosted usage; cloud starts around $75-80/month. Deploy on-prem, your own cloud, wherever. Good choice if you're privacy-sensitive or have compliance constraints early.
> 
> **3. ConfigCat** - The cheapest sane managed option, from ~$25/month, with a 10-minute setup and a free tier that doesn't expire. Not flashy, but if you just want flags that work and a bill that won't surprise you, this is it.
> 
> **4. Flagsmith** - Middle ground at ~$40-45/month, open-source with both cloud and self-hosted options, free tier around 50k requests. Solid remote config alongside fl
