ClickHouse support
Pipeline Team
Check our ClickHouse manualClickHouse is, in simple terms, a very fast database. Until this point we've been using Postgres, but we've now made the change to switch to ClickHouse for larger event volumes. At the time we made this change we were handling nine-figure numbers of events each day, and ClickHouse drastically sped everything up.

PostHog FOSS launched
Product Analytics Team
Goto the FOSS repoAs an open core company, we have to reconcile our open source efforts with our ability to generate revenue. Generating revenue is how we're able to sustain our extensive work in the open source space.
Thus, after a lot of brainstorming and calls with the likes of Sid Sijbrandij, CEO of GitLab, we settled on a business model that allows PostHog to be a sustainable company in the open source space.
This led to the creation of a new repository called posthog-foss, which is a mirror of the main repository without proprietary code. Want to run your own open source version of PostHog under a permissive MIT license? Now you can.
