Deep Dive: Switching from Lucidchart to diagrams.net

Trade-offs, installation & data architecture

The Catch vs Lucidchart

What you trade away

It matches the drawing depth but has a weaker integrated team workspace for comments, review, versioning, administration, and cross-document organization than Lucidchart.

Installation

How to deploy diagrams.net

Open the web app, or install the native desktop package

Data Ownership

Where your data lives

Diagrams are local .drawio XML files or files saved to a user-selected provider such as Google Drive or OneDrive; the desktop app keeps diagram content on the machine and can export common image/document formats

Build vs Fork Verdict: KINDA (the core, yes. the polish, no)

Why fork diagrams.net instead of vibe-coding a Lucidchart clone?

The visible diagramming loop is buildable, but a credible replacement needs more than the first screen. Lucidchart earns its keep through interaction polish, collaboration, so expect a weekend or multi-day build and a narrower personal scope.
