Free alternatives to Lucidchart
4 free programs that can replace Lucidchart, each pairing checked by Radar's AI reviewer or by Radar.
Lucidchart is an online diagramming service, sold by subscription. Teams use it in the browser to draw flowcharts, organisation charts, process maps and network diagrams, and to work on them together with comments and live editing. It also connects to common work tools, so diagrams can be embedded in documents and wikis.
Before switching, check these points:
- How your existing diagrams will come across. Test an import or export with a few real files, because complex ones may lose layout details.
- Which shape libraries you need, such as flowchart, network or software design shapes.
- Whether people who still use Lucidchart need to open or edit your files. A common export format like SVG or PDF keeps things simple.
- Real-time collaboration, comments and embedded diagrams, which some simple tools do not offer.
- Where the files will be stored once they leave the online account.
