Editorial Verdict

AI-researched, not hands-on tested

PostHog's transparency is genuinely unusual for a SaaS company -- a public handbook, sales manual, and changelog, plus 98% of customers using it for free under generous usage-based tiers. The one real limitation: it's web-only and cannot be installed via continuous delivery (CD) pipelines.
