ASCII-Draw
Draw ASCII diagrams and graphics directly in the terminal
AI Summary
ASCII-Draw is a desktop application for creating diagrams and drawings exclusively with ASCII characters. The tool is designed for developers who want to create technical documentation, diagrams, or visual elements for terminals and code comments.
✓ Pros
- + Open source and freely available
- + Diagrams remain readable in any terminal without external viewers
- + Integration with GNOME Builder for easy development
✗ Cons
- − Limited visual design capabilities compared to graphical tools
- − Requires learning ASCII drawing techniques
Use Cases
- → Create technical diagrams for code documentation
- → Visualize flowcharts and process flows in README files
- → Display network and system architectures in the terminal
- → Design ASCII art for command-line tools and banners
Who is it for?
Developers and technical writers who need platform-independent diagrams for documentation, README files, or terminal-based applications.

What is ASCII-Draw?
ASCII-Draw is a desktop application for creating diagrams and drawings using only ASCII characters. The project is open source and available on GitHub. The approach is deliberately minimalist: instead of exported image files, it produces text constructs that remain readable in any terminal, Markdown file or code comment without additional software.
Core features
- Drawing diagrams, flowcharts and process flows with ASCII characters
- Creating network and system architecture sketches directly in text format
- Designing banners and ASCII art for command-line tools
- Integration with GNOME Builder for developing the tool itself
- Output as plain text, with no dependency on external viewers or renderers
Who is ASCII-Draw for?
Developers who want to enrich technical documentation in README files or inline comments with diagrams, without introducing graphical dependencies. Technical writers also benefit when target formats such as plaintext or terminal output do not support embedded images.
The learning curve is not trivial. Anyone used to drawing diagrams by drag-and-drop in graphical tools will need to adjust their thinking. ASCII characters follow a character-grid logic, and spatial arrangement requires manually counting characters and positions. For complex architecture graphics, ASCII-based representations hit structural limits.
Context & alternatives
ASCII-Draw occupies the niche of text-based diagramming tools. Those working in the browser or via CLI will find related approaches in Monodraw (macOS), Ditaa, or the text-based diagram renderer used by tools like Kroki. Text-based diagram languages such as Mermaid or PlantUML solve a similar problem in a different way: they use a syntax that is rendered automatically, but do not produce pure ASCII output.
ASCII-Draw is the right choice when the end product itself needs to be readable ASCII text and no rendering step can come in between.
