Openobserve vs SigNoz

SigNoz scores higher on the AgentReady, 52/100 against 50/100. They differ on 8 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

What each one is

Openobserve. Open source, high-performance, unified observability platform for logs, metrics, and traces, built in Rust, with SQL and PromQL support.

SigNoz. One-stop platform for all your observability needs.

Where Openobserve is ahead

Openobserve passes pricing understandable, and SigNoz does not. That is understand, whether an agent can read the docs and work out how the API behaves before calling it.

It also holds adopt: free trial or free allowance and copyable quickstart. SigNoz misses those.

And on operate, agent compatibility verified. SigNoz misses it.

Where SigNoz is ahead

SigNoz passes mcp discoverable, and Openobserve does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds adopt: no mandatory sales call and mcp integration available. Openobserve misses those.

And on operate, retry behavior documented. Openobserve misses it.

What neither does

Both fail structured api reference, openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, self-service signup, agent-compatible signup flow, programmatic credential creation, fast time to first request, structured, predictable output, machine-readable errors, idempotency support, rate-limit behavior predictable. If your agent needs any of those, you will be building it yourself either way.

Score, pillar by pillar

The AgentReady splits into four pillars, scored separately, because a product can be easy to find and still impossible to adopt.

Discover. SigNoz leads 100 to 87. Openobserve misses mcp discoverable; SigNoz misses nothing.

Understand. Openobserve leads 23 to 15. Openobserve misses structured api reference, openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented; SigNoz misses structured api reference, openapi / spec quality, authentication documented, pricing understandable, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented.

Adopt is whether an agent can get a key and make its first successful call without a human in the loop. SigNoz leads 52 to 35. Openobserve misses self-service signup, no mandatory sales call, agent-compatible signup flow, programmatic credential creation, fast time to first request, mcp integration available; SigNoz misses self-service signup, agent-compatible signup flow, programmatic credential creation, free trial or free allowance, fast time to first request, copyable quickstart.

Operate. Openobserve leads 53 to 41. Openobserve misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable; SigNoz misses structured, predictable output, machine-readable errors, idempotency support, rate-limit behavior predictable, agent compatibility verified.

Pricing

Openobserve does not publish a machine-readable starting price and has a free tier. SigNoz does not publish one.
