Axiom alternatives
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
- Managed petabyte-scale infrastructure and operational effort
- Serverless ephemeral query runtimes and Axiom's proprietary EventDB/MetricsDB optimizations
- Automatic volume-discounted usage pricing and built-in spend controls
- Self-serve enterprise compliance artifacts/certifications (SOC 2, ISO 27001, HIPAA BAA) out of the box
- Built-in AI agent features (MCP server and SRE/metrics skills) integrated into the platform
An open-source project doing the core job proves a replacement is possible. It does not prove it matches Axiom, and it does not prove anyone has run it for a month. How we decide.
