## The answer, as recorded

Asked on 2026-09-22 through Claude (Anthropic) with web search (model claude-opus-5).

> Here's what I'd actually reach for, roughly in the order I'd consider them:
> 
> **1. PostHog** - If you're a startup and don't already have strong opinions, start here. Feature flags are free alongside analytics, session replay, and A/B testing (generous free tier, ~1M events/month), so you get the whole product-instrumentation stack from one SDK instead of stitching four vendors together. Flags are genuinely good, not a checkbox feature. The tradeoff: it's a broad platform, so flag *governance* (approvals, fine-grained permissions) is thinner than LaunchDarkly's.
> 
> **2. Statsig** - The best pick if you care about experimentation as much as flagging. Flags, experiments, and metrics share one event pipeline, so "ship behind a flag → read the lift" is one workflow rather than a data-warehouse project. Free up to 2M events/month, then transparent usage pricing (~$150 at 5M). Worth knowing it was acquired by OpenAI in 2025, which some teams read as stability and others as roadmap risk.
> 
> **3. ConfigCat** - My recommendation when you want *only* flags, cheaply and predictably, with no ambition to become an analytics platform. Unlimited team members on every plan and flat per-config pricing r

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.
