✨ Features

• Real-time dashboard view of your monitored URLs
• Diff viewer (in terminal)
• Fast and lightweight
• Configurable keybindings, url and api key
• based on python's Textual

🚀 Installation

Using uv (recommended)

uvx --from changedetection-tui cdtui

Or install as a tool:

uv tool install changedetection-tui
# $PATH must contain `uv tool dir`
cdtui

Using pip

pip install changedetection-tui

Using docker

Images are pushed both on the official docker hub and on Github's container registry. The images are the same, use whatever you want.

mkdir ~/.config/cdtui/

docker run --rm -it -v ~/.config/cdtui/:/home/appuser/.config/cdtui/ -u $(id -u):$(id -g) grota/changedetection-tui
# or
docker run --rm -it -v ~/.config/cdtui/:/home/appuser/.config/cdtui/ -u $(id -u):$(id -g) ghcr.io/grota/changedetection-tui

Pushed tags

These are the docker image tags we push to both registries:

• The major-only semver tag (e.g. grota/changedetection-tui:1)
• The full semver tags (e.g. grota/changedetection-tui:1.2.3)
• The latest tag: which corresponds to the last commit on the default branch (main)

⚡️ Usage

🚀 Quick Start

cdtui --url http://your-changedetection-url-here --api-key your-api-key-here

📖 Other ways to specify URL and API key

The URL and the API key values found can also be persisted to the configuration file after launch via settings, here's a screenshot of the main section.

You can avoid storing the API key secret to the configuration file by using the environment variable syntax.

Keybindings

Current keybindings can be seen in the footer, they can be remapped in settings.

• Open Jump Mode: ctrl+j
• Quit: ctrl+c
• Open settings; ctrl+o
• Focus next: tab
• Focus previous: shift+tab
• Open palette: ctrl+p
• Move left/down/up/right: hjkl
• Dismiss jump mode: esc/ctrl+c

Roadmap

Right now the software is complete, I can review PRs for additional feature requests, but the goal is mainly to keep up with the upstream API changes.
