Open .drawio output vs. proprietary diagramming

Eraser's DiagramGPT generates diagrams from text, but in a proprietary format. Diagrams.so generates native .drawio files that work everywhere.

Overview

Eraser is a documentation-first tool with DiagramGPT, an AI feature that generates diagrams from text descriptions. The output is clean and professional, but locked into Eraser's proprietary format. There is no .drawio or standard format export.

Why teams choose Diagrams.so

  • Native .drawio export—edit in Draw.io desktop, Confluence, VS Code, not just Eraser
  • Architecture warnings engine—Eraser generates but doesn't validate
  • Community gallery with fork/remix for collaborative learning
  • Opinionated Mode suggests missing components with rationale
  • Credits-based pricing that accounts for diagram complexity
  • Import existing .drawio files for free on all plans

Verdict

Eraser is a solid documentation tool with capable AI diagramming. If you need .drawio format compatibility, architecture validation, and an open ecosystem, Diagrams.so provides those capabilities natively.

Ideal for: Eraser is ideal for teams that use Eraser for documentation and want integrated diagramming. Diagrams.so is ideal for architects who need standard .drawio output and architecture best-practice validation.

Frequently asked questions

Is Diagrams.so a good alternative to Eraser DiagramGPT?

Yes, particularly if you need portable output. DiagramGPT generates diagrams in the Eraser proprietary format, while Diagrams.so generates native .drawio files and adds an architecture warnings engine and a fork and remix gallery.

Can I import my Eraser diagrams into Diagrams.so?

Not directly, because Eraser uses a proprietary format rather than .drawio. You can recreate a diagram quickly by describing it in plain English, and any existing .drawio files you have import for free.

Does Diagrams.so export to draw.io?

Yes. Output is native .drawio XML, so diagrams open and stay editable in Draw.io, Confluence, and the VS Code extension. Eraser does not export to .drawio.

How does Diagrams.so pricing compare to Eraser?

Both offer a free tier. Diagrams.so paid plans are billed per account rather than per seat and meter usage in credits, whereas the Eraser Pro plan is a fixed monthly subscription. The better value depends on team size and how many diagrams you generate.

Which is better for cloud architecture diagrams?

Diagrams.so is more specialized for cloud architecture: it ships official AWS, Azure, GCP, and Kubernetes icons and validates designs for best-practice issues. Eraser is documentation-first and does not include an architecture validation engine.
