OpenSnowcat
OpenSnowcat is a free, open-source pipeline for collecting, enriching, routing, and loading behavioral data.
What OpenSnowcat is
OpenSnowcat is a free, open-source pipeline for collecting, enriching, routing, and loading behavioral data. It is a Snowplow fork, licensed under Apache 2.0, and can be self-hosted. Its HTTP collector accepts events from Snowplow, Segment, and Amplitude SDKs, though the Amplitude bridge is experimental. The enricher validates events against schemas and enriches them, while the Schema Registry provides REST endpoints for publishing schemas, drafts, validation, health checks, and API-key authentication. With Bento, users can filter events and anonymize, hash, or redact sensitive data; the page lists more than 60 sources and 38 outputs. Documented destinations include Amplitude, Snowflake, Redshift, S3, Kinesis, Azure Blob Storage, Elasticsearch, Google Pub/Sub, Kafka, and HTTP. Docker images and a Docker-based local DevKit are documented for development and testing. The FAQ describes use with websites and SaaS products, including high-volume production data processing. Self-hosting has no licensing fees, but data loaders require a paid license. Technical support is directed to SnowcatCloud.
