Choose Overmind if
Engineering teams with agents in production that want to improve accuracy and cost and keep ownership of the models.
- Open source and self-hostable, with weights you keep
- Covers the full loop from tracing to serving in one product

Engineering teams of any size that want to know when and why code breaks.
- Best developer experience for debugging errors
- SDKs for everything
- Free tier for individuals
Look elsewhere if: Infrastructure metrics and logs at scale (Datadog, Grafana).
