2 open-source projects that already do this job. Free to use - not free to run, which is what the numbers on the right are for.

What you give up either way
- The vendor's proprietary Unusuality algorithm and any tuned parameters
- Access to whatever raw aggregated institutional-level flows Financhle purchases
- Polish and latency of a commercial realtime feed and alerting infra
- Any included data partnerships or commercial licensing the product may have
An open-source project doing the core job proves a replacement is possible. It does not prove it matches Financhle, and it does not prove anyone has run it for a month. How we decide.
