What you can do with it
About
Upstream Watch monitors registered API endpoints and detects breaking changes by comparing responses against known schemas. Changes are confirmed across multiple observations before alerting to reduce false positives. Alerts route to Slack, webhooks, or PagerDuty with specific details of what changed. An open-source agent runs on your infrastructure so API keys and request/response data never leave your systems—only schema metadata is transmitted.
Who it is for
Engineering teams relying on external APIs in production systems who need early detection of API breaking changes.
