Jitsu

Jitsu is a powerful open-source customer data platform (CDP) and event streaming pipeline designed as a self-hosted alternative to Segment, RudderStack, and other SaaS CDPs. Built for engineers, Jitsu captures events from websites, mobile apps, and backend services through native SDKs and forwards them to data warehouses, marketing destinations, and custom HTTP endpoints with sub-second latency. With a powerful JavaScript-based transformation layer and 30+ native destinations, Jitsu lets data teams own their event pipeline end-to-end without paying per-event pricing or surrendering visitor data to third parties.

Common Use Cases

Engineering teams use Jitsu as the central event pipeline behind product analytics, replacing tools like Segment to control costs and keep PII in their own infrastructure. Data teams stream events into Snowflake, BigQuery, ClickHouse, or Redshift for warehouse-native analytics, dbt modeling, and reverse-ETL workflows. Marketing and growth teams configure destinations like Google Analytics, Mixpanel, Amplitude, Facebook Conversions API, and HubSpot from a single console, keeping all attribution data consistent across tools. Platform teams use Jitsu's source connectors to ingest data from production databases and SaaS APIs alongside real-time streams, building a unified data foundation for their organization.

Key Features

• Real-time event ingestion via JavaScript, Node.js, Python, Go, and segment-compatible SDKs
• Native destinations for Snowflake, BigQuery, Redshift, ClickHouse, Postgres, S3, and 30+ marketing tools
• Serverless JavaScript functions for filtering, enriching, and transforming events
• Source connectors using Singer and Airbyte protocols for database and SaaS API ingestion
• Built-in user profile storage for cross-device identity resolution and audience building
• Schema management with automatic column creation and type inference for warehouse destinations
• Persistent event queue powered by Redpanda for reliable at-least-once delivery
• ClickHouse-backed event log for fast debugging, replay, and exploratory queries
• Multi-workspace console UI with project-level access controls and API tokens
• Open-source MIT license with no telemetry, no vendor lock-in, and no per-event fees

Why deploy Jitsu on Hostinger VPS

Deploying Jitsu on a Hostinger VPS gives you full ownership of your customer event pipeline without paying per-event SaaS fees that scale with traffic. Dedicated VPS resources provide the headroom Jitsu's stack needs — Redpanda for high-throughput queueing, ClickHouse for fast event storage, PostgreSQL for configuration, and MongoDB for user profiles — all running on isolated CPU and memory. Self-hosting also keeps PII, identifiers, and event payloads inside your own infrastructure, simplifying GDPR, HIPAA, and SOC 2 compliance compared to routing data through third-party CDPs. With root access to the VPS, you can scale resources, tune retention, and integrate Jitsu with internal services and warehouses on your own network.
