Snowplow
The raw event stream, with schemas enforced at collection.
89
sovereigntySnowplow is a different proposition: rather than routing events to tools, it captures a rich, schema-validated event stream and puts it in your warehouse, where you decide what it means. Every event is validated against a JSON schema at collection, so the data-quality problems that usually surface months later surface immediately. Apache-2.0 core, around 7k stars, used by large organisations that treat behavioural data as an asset rather than a dashboard input. It is more work to adopt and more valuable once adopted.

What it does well
- +Schema validation at collection — bad data is caught immediately
- +Richest event data of anything here; you own the raw stream
- +Apache-2.0 core with a decade of production use
- +Built for organisations that model behaviour rather than count it
Where it falls short
- −Most complex pipeline on this page to deploy and run
- −You build the modelling layer; it gives you rows, not answers
- −Some components sit under a separate licence — check per component
- −Overkill if you just need events forwarded to four tools
