New Relic vs Sentry

Sentry scores higher on the AgentReady, 62/100 against 51/100. They differ on 12 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

What each one is

New Relic. Intelligent Observability platform that resolves issues at scale before they impact bottom line

Sentry. Application monitoring software for error monitoring, tracing, and debugging.

Where New Relic is ahead

New Relic passes pricing understandable, and Sentry 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: self-service signup, free trial or free allowance, fast time to first request and copyable quickstart. Sentry misses those.

Where Sentry is ahead

Sentry passes llms-full.txt / full agent docs and mcp discoverable, and New Relic does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds understand: structured api reference, authentication documented and limits / constraints documented. New Relic misses those.

And on adopt, mcp integration available. New Relic misses it.

Finally, on operate, agent compatibility verified. New Relic misses it.

What neither does

Both fail openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, no mandatory sales call, programmatic credential creation, structured, predictable output, machine-readable errors, retry behavior documented, 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. Sentry leads 100 to 80. New Relic misses llms-full.txt / full agent docs, mcp discoverable; Sentry misses nothing.

Understand is whether an agent can read the docs and work out how the API behaves before calling it. Sentry leads 46 to 23. New Relic misses structured api reference, openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented; Sentry misses openapi / spec quality, pricing understandable, request examples provided, response examples provided, errors and status codes documented.

Adopt. New Relic leads 65 to 50. New Relic misses no mandatory sales call, programmatic credential creation, mcp integration available; Sentry misses self-service signup, no mandatory sales call, programmatic credential creation, free trial or free allowance, fast time to first request, copyable quickstart.

Operate. Sentry leads 53 to 35. New Relic misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified; Sentry misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable.

Pricing

New Relic does not publish a machine-readable starting price and has a free tier. Sentry does not publish one.
