Draftium vs Pencil Project

Draftium is a web-based tool for creating and sharing website prototypes. Its editor lets users add or remove pages, blocks, and elements, rearrange blocks, change layouts, and adjust typography. The home page advertises more than 250 industry-oriented prototype templates and over 200 ready-to-use blocks, such as galleries, sliders, timelines, and tabs. Prototypes adapt to different devices and screen sizes. Users can publish a prototype link for others to view and comment on page elements. The Free plan costs nothing and allows up to 3 prototypes, 50 generic templates, and unlimited editing. Pro costs $99 a year; the pricing page also shows $199. It includes unlimited prototypes, 300+ templates, branding removal, a custom domain, and 24/7 priority support. Draftium focuses on website prototyping: it does not support mobile app wireframes or third-party integrations, and users cannot edit the same prototype simultaneously. Support can be asked to move a prototype to Weblium to finish the site.

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.
