About Jitsu
Jitsu is an open source event collection tool that sends data from websites, apps and other sources into a data warehouse. It is built to be warehouse first, so the warehouse stays the single source of truth.
What it does
You add one script to your website to start collecting events, then connect the apps and tools you want to capture data from. Jitsu can modify or filter events before they are stored, using JavaScript functions. The data is streamed to your chosen warehouse in near real time, so analysts can work with it within minutes.
Key features
- Add a single script tag to start collecting web events
- Collect events from web, apps, email and CRM tools
- Modify or filter events with JavaScript functions
- Stream events to your chosen warehouse in near real time
- Connectors for analytics and CRM tools
Who it's for
Developers and data engineers who want their analytics data in a warehouse without paying for a separate analytics product. It also suits small analytics teams that prefer open tooling they can inspect and adapt.
Pricing and good to know
Jitsu is open source under the MIT licence and can be used at no licence cost. The company also offers a hosted option that includes a free allowance of up to 200,000 events. Above that level, usage is charged. Self-hosting means your team runs the servers and keeps them updated.
