PostHog

Open-source product analytics + feature flags + session replay + surveys, positioned as the all-in-one alternative to Mixpanel + LaunchDarkly + FullStory + Typeform. Distinctive for self-hostable free tier (unlimited events on your infra) and its "we're the open-source everything" positioning. Cloud priced free-$450+/mo based on events + recordings. Popular with technical founders who don't want to stitch 4 tools together and prefer OSS over vendor lock-in.
