A CLI tool for monitoring website uptime, performance, and SSL certificates with real-time alerts and multi-region support.
Updo is a command-line tool for monitoring website and API uptime, performance, and SSL certificate health. It provides real-time metrics, alerting, and supports multi-region deployment to detect issues from various geographic locations. The tool helps developers and system administrators ensure their services are available and performing optimally.
Developers, system administrators, and DevOps engineers who need to monitor website/API availability and performance directly from the command line or integrate monitoring into their infrastructure.
Updo offers a terminal-native, feature-rich alternative to web-based monitoring services, with the flexibility of self-hosting, multi-region checks, and seamless integration with Prometheus/Grafana for observability stacks.

Offers an interactive TUI for live monitoring with navigation shortcuts, making it easy to track multiple targets directly in the terminal, as demonstrated in the demo GIF.
Supports deployment across 13 global AWS Lambda regions for geographic coverage, enabling distributed monitoring from multiple locations with built-in deployment commands.
Automatically formats notifications for Slack and Discord based on URL patterns, simplifying alert setup with rich, color-coded messages without extra configuration.
Exports detailed metrics like response times and SSL expiry to Prometheus, facilitating integration with existing observability stacks and pre-built Grafana dashboards.
Allows custom HTTP methods, headers, SSL verification, and response assertions, enabling complex API health checks beyond simple availability tests.
Multi-region functionality requires configuring AWS CLI, deploying Lambda functions, and managing IAM permissions, which adds significant setup overhead and potential for errors.
Relies solely on webhook notifications; lacks built-in support for other common alert methods like email or SMS, forcing users to rely on external services or custom scripting.
For per-target settings, users must create and manage TOML configuration files, as CLI flags apply globally, which can be tedious and error-prone for dynamic or large-scale environments.
Does not store historical monitoring data internally; long-term analysis depends entirely on external systems like Prometheus, adding toolchain complexity and potential points of failure.
