Downbar: Know the moment a service breaks, and the moment it's back

Claude Code and the OpenAI API went down often enough that I caught myself about to bookmark both their status pages so I could check them faster. Then I realized that bookmarking a status page is a pretty grim way to live. And the annoying part isn't even the outage, it's the few minutes you spend assuming you broke something before it occurs to you to go check. I didn't want to remember to check anything So I built Downbar. It's a small menu bar app that shows a three-bar meter and changes color based on the worst status across the services you watch. Green when everything's fine, red when something you depend on is having a bad day. Click it for the list, and you get a native notification when something goes down and another when it comes back. It reads public status pages. I seeded a catalog of a bit over 110 (AI APIs, cloud, dev tools, payments, that sort of thing) and you can paste any Statuspage, Instatus, or plain website URL on top of that. That includes your own services. A plain URL just gets pinged for reachability and latency, so I keep my API's /health endpoint in there right next to the third-party pages. And if you want the alerts to land somewhere other than your menu bar, it can POST a webhook to Slack, Discord, or any endpoint on the same up and down transitions.
