Guardrails 2.0 — block bad output before it ships

Guardrails 2.0 is live

Ship AI agents your team can actually trust.

Axon traces every agent run, scores every output against your evals, and stops the bad ones before a customer ever sees them.

The platform

Everything you need after the demo works

The distance between a convincing prototype and an agent you can leave running is observability, evaluation and control. Axon is all three, in one place.

Full-fidelity tracing

Every tool call, retry and token — captured as a single replayable trace. Jump from a customer complaint to the exact span that caused it in two clicks.

Evals on every run

Score outputs against your own rubrics, golden datasets and LLM judges. Regressions surface in CI, not in your inbox.

Guardrails that block

PII, prompt injection, tone and policy checks run inline. Failing output never reaches the user.

Cost and latency budgets

Set a ceiling per agent, per customer, per route. Axon throttles or downgrades the model before you get the bill.

Versioned prompts and policies

Ship prompt changes like code — diffed, reviewed, rolled back in one click, with an audit trail your compliance team will accept.

How it works

Wrap your agent. Keep your stack.

Axon is a thin layer, not a framework. No rewrites, no vendor lock-in, no proxy sitting in front of your model provider.

01

Install the SDK

One wrapper around your existing agent loop. Python, TypeScript, or a plain HTTP endpoint if you are somewhere else entirely.

02

Define what good means

Write evals as code or point Axon at a golden dataset. The same checks run in CI and against live traffic.

03

Ship with a safety net

Turn on guardrails, set your budgets, and let Axon page you only when something is genuinely wrong.

support-agent.ts

const agent = axon.wrap(supportAgent, {

evals: [groundedness, tone],

guardrails: { pii: block, injection: block },

budget: { usd: 0.04, ms: 800 },

onViolation: halt,

});

Tracing

Replay any run, span by span

Retrieval, reranking, tool calls, retries and the raw model response — all stitched into one timeline with the exact prompt and token counts attached.

Evals

Catch regressions before your users do

Run your rubrics against every deploy and a rolling sample of production traffic. When a score drops, Axon tells you which prompt change did it.

Customers

Teams that stopped guessing

“We went from three engineers reading logs every morning to nobody. Axon pages us when a score drops and shows the exact span that caused it.”

PR

Priya Raman

Staff Engineer, Verity

“The guardrails paid for themselves in the first week. We blocked twelve hundred responses that would have leaked internal documents.”

MV

Marcus Vogel

Head of AI, Halden

“Our eval suite used to be a spreadsheet somebody updated on Fridays. Now it runs on every pull request.”

FAQ

The questions we always get

Do I have to change my agent framework?

No. Axon wraps whatever you already run — LangGraph, the raw provider SDKs, or your own loop. The integration is one function call, and everything downstream stays exactly where it is.

Does Axon sit in the request path?

Where does our data live?

Can we bring our own eval logic?

What happens when we hit our plan limits?

Is there a migration path off Axon?
