AsciiFlow: Online Process Diagram Drawing Tool

ASCIIFlow is a lightweight and efficient online ASCII chart drawing tool, with its official website at https://asciiflow.com/ At the same time, provide a Chinese adapted version（ https://asciiflow.cn/ ）It can be used directly through a browser without the need to install a client, and is highly favored by developers, technical document writers, and the "geek" community.

Its core positioning is to create flowcharts, network topology diagrams, architecture diagrams, etc. through pure text characters (such as lines, arrows, rectangles, text, etc.), especially suitable for quickly presenting logical relationships in "pure text scenes" such as code comments, technical documents, and terminal environments, with a style of "easy dissemination" and "returning to simplicity".

Functionally, ASCIIFlow provides a rich and practical toolkit and features. The basic drawing tools include Boxes, Arrow, Line, Freeform, Text, etc. It supports adjusting the size and position of graphics by dragging and dropping, holding down the spacebar to pan the canvas, and using Ctrl+Z (undo), Ctrl+Shift+Z (redo), and Alt keys to view shortcut keys for smooth and efficient operation. In terms of export and save, it supports exporting as plain text files or image formats (such as PNG/JPEG), and some versions can also be saved to Google Drive. It provides two export options: ASCII mode and Extended mode, which are suitable for different usage scenarios. In addition, it continues to optimize the experience, such as enhancing Chinese input support, adding curve tools and version control functions (view/restore historical versions), and improving drawing response speed through performance optimization.

On a technical level, ASCIIFlow is developed based on web technology, with core programming languages including TypeScript, JavaScript, HTML, and Starlark. It is a client only application that does not rely on servers to process data, ensuring ease of use and data security. At the same time, it provides a desktop adaptation solution that can be run as a standalone window on macOS and Windows systems through the WebCatalog. It supports multi account management and "non-interference" drawing mode, further improving multitasking efficiency.

As an open-source project (GitHub repository: Jewish/sciiflow), ASCIIFlow is designed with simplicity and practicality as its core concept. It not only avoids the "heavy manipulation" threshold of complex graphical tools, but also meets the visualization needs in pure text scenarios, becoming an important tool for efficient communication in the technical field.
