What is Logify?

Logify is a self-hosted, open source alternative to services like Datadog, Logtail, and Sentry for log management. Ship your application logs to a single endpoint, then search, filter, and visualize them through a modern dashboard.

Why Logify?

• Simple -- One API endpoint, one API key, done
• Fast -- Neon PostgreSQL for blazing reads
• Self-hosted -- Your data stays on your servers
• Open source -- MIT licensed, no vendor lock-in
• Modern stack -- Built with Nuxt 4, Vue 3, and Tailwind CSS v4

Features

• Real-time Log Streaming -- Watch logs flow in with zero delay
• Powerful Search -- Full-text search with filters for level, service, time range, and tags
• API-First Design -- Simple REST API with comprehensive documentation
• Rate Limiting -- Built-in protection with configurable limits per API key
• Multiple Environments -- Separate logs by production, staging, and development
• API Key Management -- Generate, rotate, and revoke keys from the dashboard
• Authentication -- Secure user accounts with session-based auth
• Dark Mode -- Beautiful dark theme designed for developers

Quick Start
