The Verdict
PostHog is built for developers and startups, with a focus on product-analytics and session-replay. Rocket.Chat targets security conscious organizations and government and leads with channels and direct-messaging.
Pricing is close: PostHog starts at $0/mo versus $4/mo for Rocket.Chat — not a deciding factor on its own.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
PostHog edges out on user ratings (4.5 vs 4.1). While both are well-regarded, that gap reflects real differences in user satisfaction worth considering.
Feature-wise, PostHog offers broader built-in capabilities (7 features vs 6), while Rocket.Chat takes a more focused approach — which can mean a simpler, faster onboarding experience.
Bottom line: PostHog has a slight overall edge — but if fully open-source and self-hostable matters most to you, Rocket.Chat may still be the right call.
