Reliability infrastructure for AI agents

Stop bad agent actions before they hit production.

SafeRun sits inline between AI agents and the tools they use — validating tool calls, blocking runaway loops, pausing risky actions for approval, and giving engineers replayable incident timelines when something breaks.

See how it works
agent.pypython
from saferun import guard

@guard(policy="production")
def your_agent_action(args):
    # SafeRun validates, blocks, and logs.
    # You ship without losing sleep.
    return tool.execute(args)

Integrates in minutes. No agent rewrite required.

The problem

Agents in production break in ways traditional monitoring can’t catch.

Incident

Hallucinated tool calls

Your agent invented a customer ID and tried to call delete_customer on a record that does not exist.

Incident

Runaway loops

Your sales agent got stuck in a loop and emailed the same lead twelve times in five minutes.

Incident

Bad business actions

Your support agent attempted a $4,500 refund because a user asked nicely.

Observability tools tell you it happened. SafeRun stops it from happening.

How it works

A reliability layer between your agents and the tools they use.

01

Validate

Every agent action is validated against your policies before it executes. Tool calls with hallucinated arguments, out-of-policy parameters, malformed inputs, or unsafe patterns are caught inline.

02

Decide

Safe actions proceed. Risky actions are blocked. Ambiguous actions escalate to a human in your approval queue through Slack, email, or webhook.

03

Replay

Every decision is logged with full context. When something breaks, engineers can step through the agent run frame by frame and see exactly what happened.

What you get

Built for teams shipping agents to production.

Inline validation

Block hallucinated tool calls, malformed arguments, and unsafe parameters before they execute.

Replay debugging

Step through every agent run. See model output, tool selected, arguments, policy decision, tool result, latency, and cost for each step.

Policy as code

Declarative guardrails for what your agents can and can’t do. Versioned, testable, and deployable with your application logic.

Approval queue

Route high-risk actions to a human. Approve, reject, or modify actions from Slack, email, or webhook.

Loop & cost circuit breakers

Detect runaway agents and stop repeated calls before they burn through your API budget or annoy your customers.

Tamper-resistant audit trail

Every agent action, policy decision, approval, and blocked call is logged for debugging, incident review, and compliance workflows.

How we’re different

Observability tools watch your house burn. SafeRun stops the fire.

LangSmith, Langfuse, Helicone, Sentry, Datadog, and Arize help teams observe, trace, and debug AI systems. That is useful. But by the time you read the log, the customer record may already be deleted, the email may already be sent, or the refund may already be processed.

SafeRun sits inline before tool execution. We do not just record what happened — we intercept risky actions before they happen, block bad calls, pause ambiguous actions for approval, and create replayable incident timelines for engineers.

Traditional AI observability

Logs what happened after execution.

SafeRun

Validates, blocks, approves, and replays before production impact.
