Why the models rank PostHog — on best a/b testing tools for engineering teams
“Best all-in-one for startups and mid-size product teams — experiments sit beside analytics, flags, replay, and surveys with one SDK and one data store, so the setup cost of experimentation drops to nearly zero; open-source core, transparent usage pricing, and a developer-first culture that fits engineering teams well.”
