Jitsu Open-Source CDP

Jitsu is an open-source, warehouse-first customer data platform operated under the legal entity HV Acquisition Entity, Inc. (d/b/a Jitsu). It collects event data from web, app, email, chatbot and CRM sources so that teams can keep customer data in their own data warehouse rather than a closed vendor store.

Events are captured with a single script tag or SDK, processed in real time by JavaScript Functions that modify, filter or enrich them, stitched to user identities, and delivered to Snowflake, BigQuery, Redshift, Postgres, MySQL or a built-in ClickHouse warehouse. It runs as Jitsu Cloud, a private cloud, on premise or self-hosted under the MIT license. Named customers include PandaDoc and Investing.com.

• Event collection: a single script tag or SDK captures events from web and apps.
• Jitsu Functions: JavaScript functions modify, filter or enrich events before storage.
• Identity stitching: events are automatically linked to user identities.
• Warehouse delivery: Snowflake, BigQuery, Redshift, Postgres, MySQL and built-in ClickHouse.
• Segment compatibility: Segment-compatible API for easier migration.
• Agent and API tooling: Management API, CLI and an MCP server for AI-driven pipeline setup.

A Vietnamese e-commerce app can stream behavior events into BigQuery or ClickHouse for analytics. A fintech can self-host the pipeline on its own Kubernetes cluster to keep data in-country. A media site can reduce ad-blocker losses with a custom tracking domain.

Keeps customer event data in the buyer's own warehouse, avoiding lock-in. A free tier covers 200k active events per month and the open-source edition has no usage limits. Segment API compatibility eases migration from existing tracking. Custom domains reduce ad-blocker data loss.

Companies increasingly build customer data stacks around their own warehouse and seek alternatives to per-volume priced event pipelines. Vietnamese and Southeast Asian digital product teams, e-commerce and fintech apps with in-house data engineers are a natural fit for self-hosted, open-source tracking.
