Segment alternatives compared
RudderStack edges PostHog 95 to 88, and most of the difference is Docker support: a Docker image against no Docker image. PostHog is the busier codebase, though, with 17,556 commits in 90 days to 135. PostHog has the largest following at 41k stars, yet ranks #2 of 3, held back mostly by Docker support (no Docker image).
The most recent release is PostHog desktop-v0.61.881, published today. None of the measured options scores under 40. By stack, Go (1), Nodejs (1) and PHP (1) are the most common. PostHog is permissively licensed; Matomo is copyleft. RudderStack is source-available rather than open source, which limits commercial reuse.
2 of these 3 also appear among the Hotjar alternatives; RudderStack is specific to Segment.
