Justinmind vs Quickmock

Justinmind is an interaction design and prototyping tool for web and mobile apps. It supports wireframes, high-fidelity prototypes and simulations, with web interactions, mobile gestures, action sequences and conditions built without code. Teams can model interactive forms, data lists and grids, while simultaneous editing and version control support shared work. UI kits, synchronized components, templates and masters provide ways to reuse design assets. Prototypes export as interactive HTML, and assets as SVG or PNG; the API can generate specification assets. Deployment options include cloud, self-hosted, desktop and mobile, and integrations include Figma, Adobe XD, Sketch, JIRA and Azure DevOps. The Free plan is $0 per editor/month and includes unlimited screens but only one project. Standard is $19 per editor/month, Professional is $29 per editor/month and Enterprise is $59 per editor/month. A 10-day trial is listed. Plans include a free option, and the product is presented for design teams, business analysts and developers working on UI assets and handoff.

Quickmock is a free, open-source tool for making low-fidelity wireframes. Its editor provides pages, device frames, UI components, shapes, text components, and wireframe elements. Commands include creating and opening projects, saving and exporting, undoing and redoing, copying, pasting and deleting, zooming, and changing settings. The homepage says Quickmock is now available only on desktop, although the listed Free plan names web as its platform. The broader platform list also includes Android, iOS, Linux, macOS, Windows, API, extensions, and self-hosted use. The project README describes a VS Code extension that edits .qm files and configures an MCP server for AI tools. It also says organizations can create custom low-fidelity component libraries, with quotes available by email. Quickmock is identified as free and open source under an MIT license. Users can report bugs or request features through GitHub Issues.
