Grapholite vs Pencil Project

Grapholite is a diagramming tool for business graphics, including flowcharts, floor plans, office layouts, UML diagrams, organizational charts, mind maps, BPMN diagrams, wireframes, technical drawings, and network layouts. It also supports swimlanes, SWOT diagrams, website wireframes, workflow diagrams, TQM diagrams, Venn diagrams, planograms, and home plans. Drawing tools include ready-to-use shapes, themes, styles, a dynamic grid, snap lines, smart shapes, sketch mode, and automatic connector layout. Users can connect shapes and edit connections, positions, rotation, and scale. Floor-planning tools cover walls, windows, doors, room templates, furniture, appliances, accessories, and dimensions; the site lists over 100 furniture elements. Grapholite supports online and offline work, in and out of a browser. Diagrams can be saved locally or on a server, printed, and shared with collaborators when stored on the server. Existing diagrams can be opened from local storage or OneDrive. Exports include JPEG, PNG, PDF, SVG, and VDX Visio Drawing. The app is available on Android, iOS, macOS, web, and Windows. A time-unlimited free trial is advertised; Personal costs 49.99 USD once.

Pencil Project is a free, open-source desktop tool for creating GUI mockups, wireframes, and diagrams. Built-in stencil collections cover desktop, web, Android, and iOS interfaces; connectors and flowchart shapes support diagramming. Elements can link to pages in the same document, and those links become hyperlinks in web exports. Drawings can be exported as PNG files, web pages, OpenOffice or LibreOffice text documents, Inkscape SVG, or Adobe PDF. A clipart browser connected to OpenClipart.org lets users add vector clipart by dragging it into a project. Stencil collections and export templates can be installed as add-ons. Pencil runs on Linux, macOS, and Windows, with downloads for Fedora and Ubuntu, other GNU/Linux distributions, Windows, and macOS. The macOS DMG supports Intel and Apple Silicon. Pencil is published under GNU General Public License version 2; Evolus also describes a commercial source-code license. The site identifies version 3.1.1 as the latest stable release and warns that nightly development builds are unstable. It provides a SHA-1 checksum link for download verification and invites donations to support development.
