Lucidchart alternatives: 3 free & open-source picks
Compare recorded free and open-source options, their capabilities and operating requirements. Source dates are shown below; licenses, hosted limits and project activity can change.
Faster and friendlier for collaborative sketches and system diagrams; deliberately worse at formal templates and precision drafting.
licenseMIT
runsyour machine or their cloud
installOpen the hosted web app/PWA, or deploy the static app and optional collaboration server
dataSolo drawings are stored in browser storage or explicit .excalidraw JSON files; exports include PNG and SVG; multiplayer room data is end-to-end encrypted and the decryption key is carried in the share URL
the catch vs LucidchartIts deliberately hand-drawn style, smaller formal-shape library, and limited precision drafting make it much worse for rigorous technical and business diagrams.
setupNone for the hosted app; the trade-off appears later because durable workspace organization, centralized team administration, and managed version history are deliberately minimal

The obvious answer because it is the right one: broad diagramming, local ownership, imports, templates, and real-time collaboration through Google Drive or OneDrive.
licenseApache-2.0
runsyour machine or their cloud
installOpen the web app, or install the native desktop package
dataDiagrams 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
setup✓ installs clean
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.
facts verified 2026-08-10
Encrypted collaborative documents, whiteboards, diagrams, slides, and Kanban boards; less polished than Lucidchart, considerably less interested in your data.
licenseAGPL-3.0+
runsyour machine or their cloud
installUse a public CryptPad instance, or self-host the Node.js service behind a reverse proxy
dataDocuments are encrypted in the browser before upload; the server stores encrypted document files, blobs, and account pin metadata on its filesystem and cannot read document content
the catch vs LucidchartIts diagram tool has far fewer professional shape libraries, templates, imports, data-linking features, and precision controls than Lucidchart.
setupPublic hosting is immediate; self-hosting requires two domains or subdomains, HTTPS, strict security headers, Node.js configuration, persistent storage, and careful upgrades/backups

Lucidchart: The shapes are easy; customers pay for low-friction editing, reliable exports, collaboration, and a canvas that never fights them. The recorded subscription totals $108 a year before any costs of an alternative.
Questions about these alternatives
Is there a free alternative to Lucidchart?
Yes: Excalidraw, diagrams.net, CryptPad. These are recorded free or open-source options. Compare their feature limits, licenses, hosting costs and current availability before choosing.
Should I just build my own Lucidchart?
Our verdict is KINDA. 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. Review the scope, implementation prompt and trade-offs in the Lucidchart build guide.
