AgentTrace vs Sentry
Monitoring errors vs reproducing execution.
What Sentry is good at
- Sentry excels at error aggregation and stack traces.
- Great for alerting and traditional application monitoring.
- Builds trust with robust infrastructure for web apps.
This helps build trust — we know Sentry is a great tool.
Where Sentry stops working for agents
- Non-deterministic execution makes stack traces less useful.
- No execution replay to see what actually happened.
- No state rewind to debug complex multi-step chains.
- No safe re-execution of agent steps.

When to use both
Many teams use Sentry for high-level alerting and AgentTrace for deep reproduction and debugging of agentic workflows.
