Design and diagrams decision
SmartDraw
A minimal single‑user diagram/floor‑plan editor is feasible to build and maintain by a capable developer, but reproducing SmartDraw's enterprise integrations, template library, AI features, and brand trust is impractical without significant time and resources.

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All SmartDraw alternatives, with the arithmetic →
What a replacement has to do
- Create and edit vector floor-plan/diagram on a canvas, place/scale shapes from libraries, import raster/PDF background, export to PDF/SVG, save/load documents.
What it still won’t have
- Thousands of built-in templates and symbol libraries
- Enterprise integrations and single‑sign‑on
- Customer support, training sessions, and commercial SLAs
- AI-powered diagram generation features
- Brand recognition and enterprise trust/validation
What remains hard
- Brand trust

First-year cost
No published price
SmartDraw does not publish a price we could read, so there is nothing to compare against. What building costs is below.

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a single‑user web diagram and floor‑plan editor using React + TypeScript for frontend, SVG canvas (or Fabric.js) for drawing, Node.js + Express and Postgres for backend, and S3 for file storage. Implement: interactive pan/zoom canvas, drag/drop shape library with snapping and scale, import raster/PDF as background with user-controlled scaling, export to PDF and SVG, and save/load documents with user auth (email or OAuth). Out of scope: real‑time multiuser collaboration, enterprise SSO, trained AI diagram generation, and thousands of prebuilt commercial templates. Include error handling, input validation, and unit/integration tests for core API endpoints and canvas save/load.
How we checked
How the score was reached
- Partly verdict base52
- An open-source build was found+5
- 5 cited sources+3
- 3/3 assessment runs agreed+4
- Evidence score64
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
