In the critical infrastructure of modern tech operations, uptime monitoring serves as the central nervous system. As developers increasingly favor self-hosted solutions for control and privacy, a new open-source contender has emerged: Peekaping. Built with Go and React, this monitoring platform positions itself as a modern alternative to popular tools like Uptime Kuma, emphasizing extensibility and type safety across its architecture.

The Go-React Advantage

Peekaping's technology stack reflects deliberate engineering choices. The backend leverages Go () for its efficiency and small footprint, while the frontend utilizes React () with TypeScript () for maintainability. This combination enables:

  • High-performance monitoring checks with minimal resource overhead
  • Strong typing throughout the codebase reducing runtime errors
  • Modular design allowing easy integration of new monitors or databases

"Peekaping is designed for extensibility," explains the project documentation. "Developers can seamlessly add new notification channels, monitor types, and even swap out the database layer without major refactoring."

Monitoring Capabilities Beyond Basics

The platform supports an impressive array of monitoring targets beyond standard HTTP checks:

| Infrastructure          | Protocol/Databases      | Specialized Systems    |
|-------------------------|-------------------------|------------------------|
| • HTTP/HTTPS            | • PostgreSQL            | • Docker containers    |
| • TCP                   | • MongoDB               | • gRPC services        |
| • Ping (ICMP)           | • Redis                 | • SNMP devices         |
| • DNS                   | • MySQL/MariaDB         | • Kafka producers      |
| • Push webhooks         | • MS SQL Server         | • RabbitMQ             |

When failures occur, Peekaping triggers alerts through 25+ channels including Telegram, Slack, PagerDuty, and even WhatsApp via WAHA bridges. Additional features include:

"SSL expiration tracking, brute-force login protection, multi-factor authentication, and customizable status pages with SVG badges – crucial for teams needing public-facing status portals."

Beta Status and Developer Roadmap

Currently in beta, the maintainers explicitly caution against production use. Key limitations include:

  • No multi-user support or access controls
  • Missing incident management features
  • Limited migration path from Uptime Kuma

The public roadmap reveals ambitious plans including Playwright integration for browser-based monitoring, Microsoft Teams alerts, and Homepage dashboard widgets. Early adopters can deploy via Docker with SQLite in minutes:

docker run -d --restart=always \
  -p 8383:8383 \
  -e DB_NAME=/app/data/peekaping.db \
  -v $(pwd)/.data/sqlite:/app/data \
  0xfurai/peekaping-bundle-sqlite:latest

Why This Matters for DevOps Teams

As organizations scrutinize SaaS tooling costs and data residency requirements, self-hosted monitoring gains strategic importance. Peekaping's MIT license () and Go foundation offer compelling advantages:

  1. Resource efficiency: Single binary deployment avoids Node.js dependency chains
  2. Customization potential: Well-architected extension points for organization-specific needs
  3. Type safety: Reduced configuration errors through strict typing

While not yet production-ready, Peekaping represents a significant evolution in monitoring tool design. Its technology choices reflect modern DevOps priorities – and if execution matches ambition, it might just become the monitoring suite that developers actually enjoy maintaining.
