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
- Fixes arrive as reviewable git diffs instead of opaque changes
Look elsewhere if: Teams that only need LLM tracing inside a broader monitoring stack (Datadog) or have no production traffic yet.
Choose Polylane if
Small platform and backend teams running on Cloudflare, Vercel or AWS who want an AI first responder without hiring an SRE.
- Free plan for two members and two cloud accounts
- Read-only Cloudflare access with no full-access option offered
- MCP and API reads are unlimited on every plan
Look elsewhere if: Teams that need a mature, full observability suite with predictable usage pricing (Datadog, Sentry).
