What Vexlio is
Vexlio is an interactive diagramming tool for flowcharts, UML diagrams, block diagrams, state machine diagrams, software architecture diagrams, and math diagrams. Users can attach popups to shapes to reveal extra information without crowding the main diagram; popups can contain rich text, images, code, tables, and sub-diagrams. The editor includes smart snapping, alignment guides, precision controls, and live-edit LaTeX equations. Published diagrams open in a browser from a link, without requiring viewers to sign in or install software, and can be embedded in an iframe. The free plan includes three documents, up to 200 objects per document, viewer links that expire after three days, and PNG/JPG export. Paid exports add PDF and SVG. Vexlio imports PNG, JPEG, and SVG images, retaining the vector nature of imported SVGs. It is available on the web and can be self-hosted via docker-compose; licensing details are available by contacting the company. The FAQ says documents are encrypted at rest and private unless explicitly shared. Vexlio identifies process documentation, infrastructure maps, and legal or regulatory frameworks as use cases.
