Jitsu is an open-source event data collection platform that streams customer events into a company's own data warehouse.
Jitsu collects event data from web pages, applications, email, chat, and CRM systems through a single tag or API, then streams it in real time into the customer's own data warehouse, including a bundled ClickHouse option. The project is open source, which lets engineering teams self-host the collection layer rather than routing events through a vendor-managed store.
The platform also provides in-flight JavaScript functions for filtering, transforming, and enriching events before delivery, and exposes warehouse, storage, and fetch APIs to those functions. It competes for the same buyer problem as a warehouse-native customer data pipeline: capturing first-party behavioural events without creating another data silo.
