What is pingflare?

Pingflare delivers a complete uptime monitoring dashboard for websites, APIs, and heartbeats, tracking uptime percentage, response times, and incidents with real-time graphs and stats. Users get HTTP checks with auth support, customizable intervals, SSL validation, and alerts via Discord, Slack, Telegram, email, or webhooks—no servers or subscriptions needed. Built with Svelte for the frontend and Cloudflare Workers plus D1 database, it deploys to your Cloudflare account in minutes for free uptime monitoring.

Why is it gaining traction?

It stands out as a zero-cost, serverless alternative to self-hosted tools like Uptime Kuma or paid services, running entirely on Cloudflare's free tier with cron checks and public status pages shareable via simple slugs. Developers love the one-click deploy, heartbeat endpoints for cron jobs (like uptime GitHub Actions), and rich notifications without Grafana or Sentry overhead. The open-source uptime tracker emphasizes reliability with surge protection, reminders, and 90-day uptime graphs.

Who should use this?

Solo devs or small teams monitoring personal sites, APIs, or side projects need a lightweight uptime monitor without infra hassle. It's ideal for open-source maintainers sharing public status pages or those replacing basic GitHub uptime checks with detailed stats and alerts. Avoid if you need enterprise-scale like thousands of monitors or Grafana integrations.

Verdict

Try it for free uptime monitoring on Cloudflare—solid for low-volume use despite 19 stars and 1.0% credibility score signaling early maturity. Docs are clear for quick setup, but expect tweaks as it grows beyond hobbyist dashboards.
