Pingflare

Every minute, a Cron Trigger runs Pingflare's health checks, writes the results to D1 and feeds a public status page with 90-day uptime bars and incidents. Checks can chain several requests and assert on status codes, response times, JSON paths and headers. Alerts go to Slack, Discord, webhooks or browser push.

You build checks in a visual editor, without writing code. A multi-step check can log in, extract a token and then call an API, with assertions at each step. Severity rules mark a service as degraded or down. The public page at /status groups monitors and carries incident updates. Each monitor has its own alert routing. The installable PWA turns alerts into native push notifications on a phone. The dashboard uses email and password sessions with admin, editor and viewer roles. Pingflare is a SvelteKit app built into one Worker, with Workers Static Assets and a D1 database. The every-minute Cron Trigger authenticates with a CRON_SECRET.

Built for: Small teams and self-hosters who want uptime checks and a status page inside their own Cloudflare account

What you can use it for

• Monitor APIs and websites every minute from Cloudflare's network
• Publish a status page with incident updates for a small service
• Test a login flow end to end with a multi-step script
• Get Slack or Discord alerts when a service degrades or goes down

Deploy

• One-click · main path

  Branch main

  Deploy to Cloudflare

• CLI

  Branch main

  Replace database_id in wrangler.toml with the ID that wrangler d1 create prints before building, as the README's manual setup says.

  git clone https://github.com/isala404/pingflare.git
  cd pingflare
  bun install
  bunx wrangler login
  bunx wrangler d1 create pingflare-db
  bun run build && bun run deploy
  openssl rand -hex 32 | bunx wrangler secret put CRON_SECRET

  Copy

The Deploy button prompts for CRON_SECRET and runs D1 migrations. Then open the Worker URL and create the admin account.

What it needs to run

• D1 databasespingflare-db
