Trace runs block by block
Sim captures every step of a run, each block, tool call, and model response with its duration, so no agent decision is a black box.
Logs is the visibility layer in Sim, the open-source AI workspace where teams build, deploy, and manage AI agents. Sim records every agent run block by block, so teams trace each decision, tool call, and output, filter and search across every run, and catch failures with alerts.
Logs
Trace every agent decision, block by block, in Sim.
Logs give teams full visibility into every run in Sim, the open-source AI workspace. Follow each agent run block by block, filter and search across every run, and catch failures the moment they happen.
Companies building AI agents with Sim
See exactly what every agent did.
Sim records every agent run block by block, so teams can follow each decision, tool call, and output on one timeline.
Watch runs as they happen
Sim shows each run the moment it starts, with its trigger, duration, and output, so teams see agents working in real time.
Every run on the record
Sim keeps a permanent history of every run and follow-up, so teams can answer what happened, when, and who resolved it.
Catch failures before they spread.
Sim surfaces failed runs the moment they happen, with the alerts and context teams need to fix them fast.
Filter to the runs that matter
Search and filter every run in Sim by workflow, status, trigger, and time, so one failure is never buried under a thousand successes.
Debug with full context
Sim snapshots each run, so teams open a failed run with its inputs, outputs, and trace intact and see exactly which block broke.
Catch failures with alerting
When a run fails, Sim alerts the channel your team already watches, naming the failing block and linking straight to the trace.
