GetSignal vs Trench

GetSignal has no write-up on Specifiction yet; its figures are above.

Trench is open-source infrastructure for collecting, processing, querying, and routing real-time event data. It is built on Apache Kafka and ClickHouse, and the project says a single node can process thousands of events per second with Kafka. Users query incoming data through SQL or REST and can send it to other destinations using throttled webhooks. Trench supports the Segment specification, including Track, Identify, and Group, for server-side collection and event routing. Deployment is self-hosted: a production-ready Docker image includes Kafka, ClickHouse, and the application, and the Open Source plan runs on any cloud provider. Trench is released under the MIT License and the site describes it as GDPR compliant. The Open Source plan costs nothing, has no usage limits, and includes community support through Slack. Enterprise uses volume-based pricing and adds dedicated infrastructure, support, and deployment options.
