Developer Automation
Trigger CI/CD pipelines, refresh datasets, and automate internal workflows the moment any external web content changes. Event-driven automation without polling infrastructure.
The challenge
The data you need is public.
The alerts are not.
Development workflows depend on external data sources — API docs, partner changelogs, dataset portals, CVE databases — but there's no event-driven way to react when those sources change. You run jobs on fixed schedules, wasting compute on stale data, and discover breaking changes in production rather than the day they were published.
Why DiffHook
Event-driven, not cron-driven
Refresh datasets, trigger builds, and run ETL only when upstream content actually changes — not on a fixed schedule that wastes compute on stale data.
Webhook to any CI/CD system
GitHub Actions, GitLab CI, Jenkins, Airflow, Prefect — any system that accepts an inbound HTTP call becomes an event consumer.
CVE and security advisory coverage
Monitor NVD, NIST, and vendor security pages for CVEs affecting your stack. Trigger dependency audits automatically the day a vulnerability is disclosed.
Zero scraping infrastructure to maintain
DiffHook handles polling, JS rendering, retries, and rate limit backoff. You maintain no scraping code — just a webhook endpoint to receive events.
How it works
Three steps to production
Connect the external source
Partner API docs, upstream changelogs, CVE databases, dataset portals, version release pages — anything with a public URL.
DiffHook polls the source
When the changelog updates, when a new CVE is published, when a dataset version changes — an event fires immediately.
Trigger your pipeline
Call the GitHub Actions dispatch API, post to a build webhook, update a database record, or run any downstream automation — automatically.
Use cases
What teams build with this
API changelog monitoring
Webhook → GitHub ActionsGet a webhook when a partner's API changelog updates. Trigger a review task before you discover breaking changes in production.
Dataset refresh triggers
Webhook → Airflow DAGMonitor public dataset portals and trigger your ETL pipeline only when new data is actually available — not on a fixed cron schedule that wastes compute on stale data.
Security advisory alerts
Webhook → Jira ticketWatch NVD, NIST, and vendor security pages for CVEs affecting your stack. Trigger immediate dependency audits the day a vulnerability is disclosed.
Dependency release tracking
n8n → PR draftMonitor npm, PyPI, or GitHub releases pages for key dependencies and get notified when a new major version drops — before it breaks your CI.
