AI agent testing, replay, and monitoring

Ship AI agents you can actually trust.

AgentGuard gives production AI agents a safety layer: replay every run, trace every tool call, catch risky behavior, test prompt changes, and monitor cost before an agent surprises your users.

Pain points

AI agents fail in the middle, not at the final answer.

Most teams can read the response. Few can explain the path that produced it. That gap is where production incidents, surprise bills, and customer trust problems begin.

Pain 01

You cannot see why the agent made a decision.

A customer receives a bad answer, but your logs only show the final output. AgentGuard records the prompt, model calls, retrieved context, tool calls, and policy checks in one replayable timeline.

Pain 02

Tool calls can create real business damage.

Agents do not just talk anymore. They refund orders, send emails, update CRMs, delete records, and trigger workflows. AgentGuard flags risky tool calls before they become expensive mistakes.

Pain 03

Prompt changes break behavior silently.

A small prompt edit can change which API an agent calls or whether it asks for approval. AgentGuard makes prompt regression testing part of the release flow for production AI agents.

Core features

Observability and control for production AI agents.

AgentGuard combines agent replay, guardrails, regression testing, and cost monitoring so developers can move from agent demos to reliable workflows.

01

Agent run replay

Replay every agent run as a clean timeline with prompts, LLM calls, retrieval context, tool inputs, tool outputs, errors, latency, and cost.

02

AI agent guardrails

Create rules for refunds, deletion, outbound email, sensitive data, cost limits, prompt injection attempts, and human review requirements.

03

Prompt regression testing

Build test cases for expected behavior, forbidden tool calls, and required approvals. Compare agent versions before shipping prompts, models, or tools.

04

Cost and latency monitoring

Track token usage, model spend, tool retries, slow steps, loop patterns, and cost spikes by project, environment, customer, and agent version.

Use cases

Built for teams putting agents into real workflows.

The first version of AgentGuard is focused on developers and small teams that need production confidence, not another agent builder.

Customer support agents

Stop refund, cancellation, and escalation mistakes.

Enforce approval rules, replay support incidents, and monitor whether your AI support agent followed policy before touching CRM, refund, ticketing, or email tools.

Sales and revenue agents

Control what agents promise to prospects.

Trace outbound messages, quote generation, CRM updates, meeting booking, and qualification logic. Flag risky claims before a sales agent sends them.

Developer and coding agents

Know which step broke the build.

Monitor coding agents that read files, call tools, create patches, run tests, or open pull requests. Replay the exact sequence that produced an incorrect change.
