SchemaSentry

SchemaSentry is a web app for teams running no-code automations (Zapier, Make, n8n, Pipedream) that silently break when an API changes. You connect your critical workflows, and SchemaSentry continuously replays lightweight “canary” requests against each API endpoint, validating response shape, status codes, auth scopes, and rate-limit behavior. When it detects a breaking change (missing field, renamed property, new pagination, stricter validation), it alerts you with a clear impact report: which workflows are affected, what changed, and the fastest workaround (e.g., map a new field, adjust query params, refresh OAuth). It also keeps a versioned history of schemas and payload examples so non-developers can understand what changed without reading docs. This is not another integration builder; it’s reliability monitoring for the integrations you already rely on.
