SendCheck
An open-source automated quality-assurance tool for workflow outputs. It integrates with automation platforms such as n8n via webhook to independently verify output quality, detecting silent failures including empty responses, malformed JSON, and unfilled template placeholders. It supports alerting via email, Slack, and Discord, as well as a historical-records dashboard.
Timeline (last 90 days)
SendCheck is an open-source tool positioned to act as an independent result review layer at the end of an automation pipeline, rather than as a replacement for n8n.
SendCheck receives the final results sent via Webhook after n8n's main workflow has completed, and then performs validation.
SendCheck performs item-by-item checks for failure characteristics including empty responses, field errors, unfilled templates, malformed JSON, and AI refusals to generate content.
SendCheck does not need to be installed inside n8n, nor does it depend on n8n's plugin system; it communicates only via standard HTTP protocol.
SendCheck pushes alerts to email, Slack, or Discord when an anomaly is detected.
SendCheck provides an independent dashboard that saves execution history, with records of each execution archived for review.
The pattern of extracting output quality validation from the main workflow into a pluggable independent layer applies to any automation system involving AI generation and data flow.
The integration cost of SendCheck is primarily adding a Webhook call at the end of the workflow.
