Peekaping: Extensible Uptime Monitoring for Self-Hosted Teams
Peekaping is a Go and React self-hosted uptime monitor covering network, service, and database checks with status pages, notifications, and an API. It remains in beta, so teams should evaluate changing features, storage, and operations before adoption.
What it is for
Peekaping is a self-hosted uptime monitoring system built with Go and React. It is aimed at individual developers, operations teams, and DevOps teams that want to run their own monitoring platform. It can check websites, APIs, network services, containers, databases, and selected messaging systems, then send notifications when status changes. The project is licensed under the MIT License, with source code, documentation, and deployment files available in its GitHub repository.
Its scope goes beyond periodically requesting a web page. The README lists HTTP/HTTPS, TCP, ICMP Ping, DNS, Push, Docker, gRPC, and SNMP monitors, as well as PostgreSQL, Microsoft SQL Server, MongoDB, Redis, and MySQL/MariaDB. MQTT, RabbitMQ, and Kafka Producer are also listed. Before adoption, teams should verify each required monitor type against the current documentation and release behavior.
Known features
The project provides status pages, SVG status badges, alert notifications, SSL certificate expiration checks, multi-factor authentication, and brute-force login protection. The README also describes an API-first design, API key management, and access control. These features may suit teams that want to connect monitoring configuration to automation or infrastructure-as-code workflows. However, feature labels alone do not establish an organization’s audit, authorization, or compliance requirements; those boundaries must be checked in the actual deployment.
Release 0.0.47 added an optional Prometheus metrics endpoint, SMTP monitoring, Microsoft Teams notifications, signed webhook requests, and a stale-monitor watchdog for monitors that have not been checked for an extended period. The Prometheus endpoint is disabled by default. The release notes state that it requires no credentials and exposes monitor names, so it should be restricted to a private network. That is an important deployment consideration, not a general security guarantee.
Deployment considerations and limits
The README documents SQLite and PostgreSQL storage and says that MongoDB still works but is deprecated; new deployments should evaluate SQLite or PostgreSQL first. Single mode is presented for new installations, while cluster mode is described for installations that need to scale out. The supplied sources do not provide minimum hardware requirements, capacity limits, or performance benchmarks, so they cannot support a claim about a particular monitoring scale.
The main adoption constraint is project maturity. The README explicitly marks Peekaping as beta, notes that features may change, and recommends testing in non-production environments. Its roadmap also lists unfinished work such as incidents, a migration tool, multi-user support, and access levels. Before production use, teams should validate upgrade procedures, backups and restores, notification failure handling, API permissions, database migrations, and reverse-proxy configuration. If Prometheus metrics are enabled, their network exposure should be deliberately limited. The project provides official documentation and a demo, but those do not replace operational testing.
Peekaping is therefore a plausible fit for teams willing to maintain a self-hosted service and needing multiple monitor types plus programmable integration. If the priority is an immediately mature production monitoring platform, its beta status and evolving feature set should be treated as central decision risks.
