Check URLs, TCP ports, and DNS records on a schedule. Get alerted when they fail. See historical uptime. Better Uptime without the $20/mo for something a binary can do.
Running a uptime and health monitor should not require a Kubernetes cluster, a managed database, and a DevOps team to keep it running. Bellwether is one file. Download it, run it, point your browser at it. That is the entire setup.
A non-profit with no DevOps budget downloads the Bellwether binary, sets two environment variables, and runs it on the same Linux box that handles their email. It has been running for three months without intervention. When they need to update, they download the new binary and restart the process.
The dashboard opens at /ui and gives you a search bar, status filters, and a create form. Double-click any check to edit it inline. Behind the dashboard, every operation maps to a REST endpoint under /api/checks. Responses are JSON. Authentication is handled at the network level — put Bellwether behind your VPN or reverse proxy, and it serves requests to whoever can reach it.

Send JSON with at least nameGET /api/checks/{id} — Fetch one check by IDPUT /api/checks/{id} — Update fields on an existing checkDELETE /api/checks/{id} — Remove a checkGET /api/stats — Returns total count and breakdown by statusGET /api/health — Returns {"status":"ok"} for uptime monitoringSelf-hosted uptime and health monitor.
