Uptime Monitoring That Actually Works

HTTP, keyword matching, and string-based checks from multiple global locations. Every alert is double-checked from a second node to eliminate false positives.

  • HTTP & keyword checks — Verify status codes, response content, and page elements
  • Double-check from multiple geographical locations — No false alarms from network blips
  • 30s to 1h intervals — Choose the frequency that fits your needs
  • Response time tracking — Full timing breakdown with detailed metrics

Frequently Asked Questions

1 check = 1 credit. Every time we ping your website or endpoint, it costs exactly one credit. Buy credit packs starting at €5 for 200,000 credits. The more you buy, the cheaper per credit. There are no monthly subscriptions, no tiers, and no feature locks. Every feature is available to every user.
Pulse+Data lets you push any metric from your infrastructure to chglog and set up alerting rules. Monitor signup flows, API response data, disk space, memory usage, Docker container health, database query times — anything that can send an HTTP request. Define thresholds and get alerted when values go out of range.
Every HTTPS check automatically monitors your SSL certificate (expiration, issuer changes, chain issues) and your domain's WHOIS data (domain expiry, registrar changes, DNS snapshots). No setup required — it just works. Most competitors charge extra for these features.
When a check fails, we immediately re-check from a different global location. You only get alerted if the failure is confirmed from multiple nodes. This eliminates noise from temporary network glitches, regional issues, or ISP problems.
No. There are no subscriptions and no commitments. Buy credit packs when you need them, and they never expire. You start with 100,000 free credits so you can try everything before spending a cent.
Email, Slack, Discord, Microsoft Teams, and custom webhooks. iPhone push notifications via the Chglog app are coming soon. You can set up multiple channels per check and customize which events trigger notifications.
Yes. Create branded public status pages with your logo, colors, and custom domain. Status pages include real-time component status, incident timelines with updates, and a post-mortem blog for detailed write-ups. Your customers stay informed automatically.
Describe what you want to monitor in plain language — "Monitor my checkout API and alert me if response time exceeds 2 seconds." Our AI generates the Pulse+Data integration code, string matching rules, and alert thresholds. Copy the code, deploy it, and you're monitoring in minutes.
