  • Ask HN: What are you working on? (April 2026) (Non AI)
    Still OnlineOrNot (https://onlineornot.com/) - I've been working on adding more and more configurability to the browser checks feature. More recently, I've made it so you can drop your existing playwright test suites into the code editor, and it'll Just Work. A whole bunch more work to do around that, but I think letting folks drop code in makes more sense than continuously updating the UI. - Source: Hacker News / 5 months ago
  • Ask HN: What Are You Working On? (March 2026)
    I've been celebrating five years of working on OnlineOrNot (https://onlineornot.com/) by adding more features for teams that build software: - 2FA, PassKey, and password-based login for folks that hate magic links - Moved my entire API from GraphQL to REST so I can fully dogfood the API I offer - Added an audit log as standard on all plans - Built a terraform provider... - Source: Hacker News / 6 months ago

Uptime checks are now fully powered by a public API (still have heartbeat checks, maintenance windows, and status pages to go). Doing this both as a means of dogfooding, and adding features to the REST API that I easily dumped into the private GraphQL API without... - Source: Hacker News / 11 months ago
  • Ask HN: What Are You Working On? (September 2025)
    I'm rebuilding OnlineOrNot's frontend to be powered by the public REST API. Doing this both as a means of dogfooding, and adding features to the REST API, that I easily dumped into the private GraphQL API without thinking too hard. Basically I've realised GraphQL has taken me as far as it can, and I should've gone with REST to start with. That, and after I finish the first milestone (uptime checks + cron job... - Source: Hacker News / 11 months ago
