Incident response for
Trace every run, replay failures deterministically, and block regressions before they ship. Runtrail works across any model, framework, or runtime.
Agents break differently than software.
Not reproducible
Tool responses change, state drifts, integrations flake. You can't just "re-run" an agent and expect the same failure.
of agent failures are non-deterministic
Telemetry is fragmented
LLM calls, tool calls, and app logs don't line up. Piecing together what happened across systems takes hours.
hours avg to reconstruct a single failure
Fixes don't stick
Prompt tweaks ship without regression coverage. The same failure class resurfaces a week later in a different run.
of resolved agent bugs recur within 30 days
Runtrail closes the loop.
How it works
From instrumentation to CI gates in four steps.
Instrument runs
Add an SDK/exporter in minutes to capture model calls and tool calls.
Reconstruct the timeline
One coherent run view with version, ownership, cost, and the failure point.
Replay safely
Tool responses stubbed by default. Optional model stubbing for exact reproduction.
Prevent recurrence
Turn incidents into regression checks and enforce release gates in CI.
Works with your stack
Everything you need to go from incident to prevention.
Run Explorer
Search and filter across all agent runs.
- Search runs by version, tool usage, or error class
- Error clustering and correlation IDs
- Filter by time range, owner, or status
- Deep-link to any span in the timeline
Deterministic Replay
Reproduce failures exactly as they happened.
- Replay bundles with stubbed tool responses
- Replayability score per run
- Safe-mode defaults, optional model stubbing
- Derived runs you can diff against the original
Regression Checks
Turn incidents into permanent test coverage.
- Create checks directly from a run
- Assertion library for outputs, tool calls, and costs
- Visual diffs between expected and actual behavior
- Check history with pass/fail trends
Release Gates
Block bad deploys before they reach production.
- Gates per environment (staging, production)
- CI integrations (GitHub Actions, GitLab, etc.)
- Evidence-linked failure reports
- Block deploys until regressions pass
Built for teams where agent failures have real consequences
Customer support automation
Incident
A support agent auto-applies a $500 refund instead of a $5 credit because the LLM misparses the order total from a tool response.
With Runtrail
Runtrail replays the run, pinpoints the calculation step, and creates a regression check that catches any refund exceeding the order-level threshold.
Internal IT automation
Incident
A provisioning agent grants admin access to a shared resource because the role lookup tool returned stale data during a brief outage.
With Runtrail
Replay with stubbed tools reproduces the issue instantly. A regression check ensures role assignments always match the latest directory state.
Finance/risk ops workflows
Incident
A compliance-checking agent skips a required sanctions screen because an upstream API returned a partial response that the model interpreted as "clear."
With Runtrail
The run timeline shows the missing field. A regression check validates that every compliance run covers all required screening steps before proceeding.
Platform teams managing agent fleets
Incident
A new model version causes three different agent types to regress silently. The issue surfaces only when customers report incorrect outputs days later.
With Runtrail
Release gates block the deploy when regression checks fail across agent types, catching model-version regressions before they reach production.
Not another agent platform.
A reliability layer that works with what you already use.
We don't replace your framework.
Runtrail sits alongside your existing agent framework and orchestration code. Keep LangGraph, CrewAI, OpenAI Agents SDK, or your custom setup.
We don't force a single vendor.
Neutral across model providers. Use OpenAI, Anthropic, Gemini, open-source models, or mix them. Everything carries over when you switch.
We focus on engineering workflows.
Replay, diff, regression artifacts, and CI gates tied to real failures. A reliability layer, not another agent builder.
Using MCP or a tool gateway? Runtrail can ingest telemetry from that layer and turn incidents into regression checks and release gates. They work well together.
Built for production from day one.
Redaction-first ingestion and configurable payload capture
Encryption in transit and at rest
Tenant isolation
Retention controls
Replay safety: no mutating calls unless allowlisted
Enterprise roadmap
SSO, RBAC, and on-prem deployment options are planned for early pilot partners.
