LibrePing is free, open-source monitoring software for websites and services. It checks targets from multiple locations and shows reachability on a live map, with HTTP(S), TCP, DNS, TLS certificate, ICMP ping, and traceroute checks. The dashboard provides a geographic map, network overview, and uptime and latency timelines with location details and recent checks. Hubs exchange results through a peer-to-peer libp2p gossip mesh instead of a central server, and duplicate targets are monitored once across the network. The browser dashboard creates an identity key without signup; a recovery phrase can move it to another device. Alerts support ntfy, Discord, Slack, and raw webhooks. Destinations are encrypted for notifying hubs, failed sends retry, and failover can produce duplicate notifications. Users can run hubs or probes with Docker images and Compose setups. AGPL-3.0 licensing requires sharing modifications when a modified version runs as a network service.
Who it is for
LibrePing suits people monitoring their own services across countries, contributing a probe, or hosting a federated hub. It is also intended for users who want self-hosted or API-accessible monitoring.
What is good
- Multiple geographic monitoring locations
- HTTP, TCP, DNS, TLS, ICMP, traceroute checks
- Peer-to-peer federation without a central server
- Encrypted alert destinations
- Docker hub and probe deployments
What to know first
- Default probe cap is 300 checks per minute
- Detailed results retained seven days by default
- Probe locations lack cryptographic geographic proof
- Failover may send duplicate alerts
Verdict
LibrePing provides decentralized, self-hostable monitoring with signed results, shared checks, dashboards, and alert integrations. It is free under AGPL-3.0, with configurable probe limits and default history-retention periods.
