A CLI tool that sends notifications when Docker images are updated on registries.
Diun is a command-line tool that monitors Docker registries for image updates and sends notifications when new versions are detected. It solves the problem of manually tracking container image changes, helping users maintain up-to-date and secure deployments.
DevOps engineers, system administrators, and developers who manage containerized applications and need to track image updates across multiple registries.
Developers choose Diun for its simplicity, reliability, and support for multiple notification channels, making it an efficient solution for automated image update monitoring without complex setup.

Distributed as a single executable with no external dependencies, making it easy to deploy without complex setups, as highlighted in the README's emphasis on simplicity.
Monitors images from Docker Hub, Docker Registry, Quay, and other registries, allowing users to track updates across diverse image sources per the key features.
Sends alerts via email, Slack, Telegram, Discord, and more, enabling integration into various DevOps workflows, as specified in the flexible notifications feature.
Available as a Docker image, which simplifies integration into existing container environments, aligning with its focus on Docker-centric workflows.
Setup involves editing YAML files for registries and notifications, which can be error-prone and time-consuming, as the documentation is external and not inline.
Diun only sends alerts and does not automate updates or deployments, requiring additional tooling for full CI/CD automation, a limitation noted in its philosophy.
Relies on periodic scans rather than real-time webhooks, potentially delaying update notifications compared to event-driven systems.
