Jitsu

Data lands in minutes, not hours: Segment loads warehouses once or twice a day (hourly at best), while Jitsu delivers per destination in batches as frequent as a minute, or row-by-row where that suits the destination. And where Segment bills by Monthly Tracked User, Jitsu Cloud bills by event volume, so the bill tracks data rather than audience size — while self-hosting has no usage billing at all.

- Free tier: 200k events/month, no credit card required.
- Unlimited destinations and unlimited captured events on every plan.
- Afree ClickHouse instanceis included, so you can go from zero to queryable event data without provisioning a warehouse first.
- Custom domains, events debugger, and the Configuration API on the free tier too.

An agent connected to Jitsu can set up a destination, wire a connection, send a test event, read the resulting Live Events, notice that a function threw, fix the function, and re-run it — the full loop, without a human in the middle.

Interactive clients useOAuth 2.1— no API key to manage. The first tool call opens a browser tab asking you to approve the connection; tokens are scoped, listed, and revocable from your account settings page.

Headless environments (CI, cron, servers) use a personal API key instead — generate one on the user settings page and pass it asAuthorization: Bearer <keyId>:<keySecret>:

claude mcp add --transport http jitsu https://use.jitsu.com/mcp \ --header "Authorization: Bearer $JITSU_API_KEY"

Jitsu is a handful of independently scalable services:

Backed by Postgres (configuration), Kafka/Redpanda (event bus), ClickHouse (live events and metrics), and MongoDB (profiles).

Jitsu is MIT-licensed and fully self-hostable, with no usage limits and no feature gating. Cloud is the path of least resistance; self-hosting is for when you need the data to stay inside your own infrastructure.

git clone -b newjitsu --single-branch https://github.com/jitsucom/jitsu cd jitsu/helm minikube start # give the VM at least 8GB RAM ./dev-deploy.sh deploy ./dev-deploy.sh tunnel # in a second terminal

./dev-deploy.sh tunnelrunsminikube tunnel, which routes the cluster's LoadBalancer services tolocalhostso you can reach them from your browser — console on:3000, ingest on:3049, bulker on:3042, rotor on:3401, plus Postgres, ClickHouse, MongoDB and Kafka. It asks forsudo(it binds privileged ports) and has to keep running in its own terminal for the whole session.
