Independent, live status for OpenAI, GitHub, Cloudflare, and the other infrastructure developers depend on. Checked every couple of minutes from each provider's own public status feed.
During PulseChecker's own launch I kept flipping between six different provider status pages trying to figure out whose fault an outage actually was. So I built downcheck.dev on top of the same Cloudflare Worker: it polls the real public status feed (mostly Atlassian Statuspage /api/v2/status.json, nothing scraped or pinged directly) for 21 services every 2 minutes, keeps 90 days of outage history per service, and tracks response time so the sparklines mean something instead of just being decorative dots.
No login, no tracking, just a clean page per service you can bookmark or share mid-incident. Would love feedback on which services are missing that you'd actually want tracked.
