pisama for n8n
Your n8n workflows fail quietly.
This catches them.
Pisama reads real workflow executions and surfaces the failures that slip through: timeouts, swallowed errors, runaway loops, and exploding payloads. Free deterministic repairs can add guards and error routes after approval. Pro adds model-generated fixes for the failures that need more context.
Choose your setup
Start where the workflow lives
Run Pisama yourself, start with hosted detection at no cost, or give your team AI-assisted fixes when a detection needs action.

Compare the full Pisama product familyEvidence-gated detectors, two lanes
Structural analysis of the workflow, runtime analysis of the execution
The structural lane reads the workflow graph itself, with precision tuned against thousands of real community workflows. The runtime lane reads what actually happened in an execution: real timings, real errors, real payload sizes, validated on a smaller corpus of real executions.
Timeout
A node genuinely ran past its threshold in a real execution, likely timing out the caller.
Classified failure
A real node error is classified as rate-limit, credential, provider, expression, timeout, or node failure.
Resource explosion
Output payloads or item counts ballooned mid-run, the pattern behind memory and quota blowups.
Unbounded cycle
A workflow graph cycle with no exit and no iteration bound. Intentional batch loops are recognized and left alone.
Excess complexity
Control flow tangled enough to be a reliability risk, calibrated on thousands of real community workflows.
Error routing
A failed execution with no error workflow, or an error route that cannot receive the incident, is surfaced only when the recorded failure proves it.
Catch it early, catch it cheap
Cheap checks run first. An AI fix runs only when a detection needs one.
Waiting for a failed run to tell you something went wrong is the expensive way to learn it. Both detection lanes are free and evidence-gated, so Pisama reads every workflow and every execution up front, then saves the paid AI fix for the detections that actually need action.
01$0 · structural
Read the workflow graph
Cycles with no exit, tangled control flow, a missing error route. Caught from the workflow itself, before an execution ever runs.
02$0 · runtime
Read every execution
Real timings, real errors, real payload sizes. Evidence-gated, so a detection fires only when the recorded run proves it.
03on approval · cloud
Fix only when it is needed
The cloud tier drafts the fix and applies it once you approve, with a snapshot to roll back. Detection itself stays free.
Three ways in
Works with n8n Cloud and self-hosted, no workflow rewrites
Community node or webhook
Install the n8n-nodes-pisama node, or point any HTTP node or error workflow at the ingest endpoint.
API polling, zero setup
Give the server your n8n API key and it polls recent executions on its own. No workflow edits at all.
Self-host in one command
docker compose up starts the detection server and this dashboard on your own machine.
Packages
Use the integration or embed the engine
The community node delivers executions to Pisama. The Python engine runs detection inside your own application. They are independent packages, so install only the surface your deployment needs.
n8n community node
n8n-nodes-pisama
Install by package name under n8n Settings, Community Nodes. It signs and sends execution data to hosted or self-hosted Pisama.
