## The answer, as recorded

Asked on 2026-10-07 through Claude (Anthropic) with web search (model claude-opus-5).

> For a startup, here's who I'd actually name, roughly in the order I'd suggest them:
> 
> **1. PostHog** - My default recommendation for most startups. Feature flags are bundled with product analytics, session replay, A/B testing, and surveys, and the free tier covers 1M flag requests/month with all features included. If you need analytics anyway (you do), this means you don't buy a second tool. The flag engine is less sophisticated than LaunchDarkly's, but for a team under ~30 engineers that rarely matters.
> 
> **2. ConfigCat** - The best pick if you want *just* flags, hosted, with no surprises. Forever-free plan with access to all features, paid plans from ~$25/mo, flat per-seat-ish pricing rather than MAU-based billing. Boring in the good way: broad SDK coverage, 10-minute integration, nothing to operate.
> 
> **3. Unleash** - Best value if you're flag-heavy or cost-sensitive. Unlimited free self-hosted open source, and the Cloud plans start around $75-80/mo with ~53M requests included. Also the reference implementation many teams pair with OpenFeature, so you're not locking yourself in.
> 
> **4. Flagsmith** - The middle ground, and my pick when you have data-residency or compliance pressure (
