Before you install
- Requires a terminal emulator that supports iTerm2's inline image protocol (iTerm2, WezTerm, or tmux with version-specific configuration).
- High install friction: source distribution only.
- Maintenance is aging—631 days since last release, though repository remains active with recent commit on 2025-04-26.

What it is and what it does
imgcat is a Python CLI and library that renders images directly in terminal emulators that support inline image protocols. It works with iTerm2, WezTerm, and tmux (with version-specific caveats), and can display images from files, stdin, numpy arrays, PIL Image objects, and matplotlib figures. The package also provides a matplotlib backend so that plotting code can render directly to the terminal instead of to a window or file.
The core use case is interactive terminal workflows where you want to see image output without leaving the shell or opening external viewers. It has no runtime dependencies, making installation straightforward on systems where the terminal emulator already supports the protocol. The main constraint is terminal compatibility—the feature only works in emulators that implement iTerm2's inline image protocol or WezTerm's equivalent.
Use it for
- Display matplotlib plots directly in the terminal during interactive data exploration or scripting.
- View image files from the command line without opening an external image viewer.
- Render numpy arrays and PIL images inline in a terminal REPL or Jupyter notebook.
- Use as a matplotlib backend in scripts to capture plot output to the terminal instead of a file.
- Pipe image data through stdin to imgcat for quick preview in shell pipelines.
