diagrams.net
open sourceApache-2.0Local or hosted62kjul 2026The obvious answer because it is the right one: broad diagramming, local ownership, imports, templates, and real-time collaboration through Google Drive or OneDrive.
The catch vs LucidchartIt matches the drawing depth but has a weaker integrated team workspace for comments, review, versioning, administration, and cross-document organization than Lucidchart.

CryptPad
open sourceAGPL-3.0+Local or hosted7.8kaug 2026Encrypted collaborative documents, whiteboards, diagrams, slides, and Kanban boards; less polished than Lucidchart, considerably less interested in your data.
The catch vs LucidchartIts diagram tool has far fewer professional shape libraries, templates, imports, data-linking features, and precision controls than Lucidchart.

Should I vibe-code or build my own Lucidchart clone from scratch?+
Our build verdict for Lucidchart is KINDA (the core, yes. the polish, no). 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.

Its deliberately hand-drawn style, smaller formal-shape library, and limited precision drafting make it much worse for rigorous technical and business diagrams.
