Monodraw

Original Article ↗ Hacker News Discussion ↗

Mac-only ASCII diagram editor Monodraw has a devoted user base that relies on it for code comments, architecture diagrams, UX mockups, and documentation, praising its focused design, anchors, and ease of use compared to heavier drawing tools. Many commenters lament that it’s in “maintenance mode,” debating whether it should be open-sourced or remain proprietary while the creator focuses limited time on OS compatibility and a few requested features like plaintext export and dark mode. The thread also surfaces a wide ecosystem of alternatives (web apps, CLI tools, Emacs modes, Mermaid, PlantUML, Draw.io), plus recurring concerns around cross‑platform support, long‑term maintainability, and accessibility of text-based diagrams.

Usage and Use Cases

  • Many long-time users; often one of the first tools installed on a new Mac.
  • Common uses:
    • Architecture and system diagrams embedded in source code comments and READMEs.
    • Buffer / data structure layouts and CSS layout sketches.
    • Documentation diagrams, UX workflows, and take‑home coding challenge diagrams.
    • Login banners, ASCII “art” sites, ads, album covers, and game‑style walkthroughs.
    • Mocking up text UIs; quick brainstorming where low visual fidelity avoids bikeshedding.
  • Some users now use Monodraw even for diagrams that could be images, due to familiarity and speed.

Product State and Development

  • App officially went into “maintenance mode” in 2018 due to poor commercial returns.
  • Developer comments:
    • Time is very limited; focus is on keeping it working with OS updates.
    • Some new features are in progress but with no promised timeline.
    • Requested features include plaintext/ASCII format, dark canvas, auto layout, tables, ANSI export.
  • Several users say it feels “complete” and that infrequent updates are acceptable.

Open Source and Sustainability Debate

  • Some argue it’s a shame a beloved but low‑maintained tool stays closed, citing bus‑factor and desire to contribute.
  • Others counter that:
    • Open sourcing is not free; community management and legal risks are real.
    • Licenses don’t reliably stop bad actors from selling clones.
  • Developer states preference for:
    • Strong centralized product vision.
    • Avoiding clone‑selling.
    • Focusing instead on open, non‑proprietary data formats for interoperability.

Platform, Alternatives, and Pricing

  • Mac‑only nature draws both praise (polish, paying user base) and criticism (no Linux/Windows).
  • Various alternatives mentioned: Asciiflow, MonoSketch, ascii-d, P5-App-Asciio, draw.io, PlantUML, Pikchr, etc.
  • Price (~$10) is widely viewed as fair; some friction around the checkout form and App Store vs direct purchase (e.g., CLI only for direct buyers).

Diagrams, Accessibility, and Technical Details

  • Embedding ASCII diagrams on the web requires monospaced fonts, code blocks, and avoiding wrapping; mobile often breaks layouts.
  • Accessibility is a concern: ASCII diagrams are generally not screen‑reader‑friendly; suggested workarounds involve treating them like images with ARIA descriptions.
  • Debate over “ASCII” vs Unicode/box‑drawing characters and terminology, but most accept “ASCII art” as shorthand for monospaced text diagrams.
