Quickmock

Quickmock is a free, open-source tool for creating low-fidelity wireframes. The maker presents it as a way to turn ideas into simple mockups for sharing. Its editor includes pages, device frames, UI components, shapes, text components, and low-wireframe elements. Editing commands cover creating and opening files, saving and exporting, undoing and redoing, copying, pasting and deleting, zooming, and settings. The project README describes a VS Code extension that adds an editor for .qm files and configures an MCP server for AI tools. Organizations can create custom low-fidelity component libraries, with quotes available by email. Quickmock is identified as open source under an MIT license, and its README invites users to report bugs or request features through GitHub Issues. The homepage says Quickmock is now available only on desktop, while the listed Free plan describes a web platform. The broader platform list also names Android, iOS, Linux, macOS, Windows, API, extension, and self-hosted use.

Quickmock focuses on low-fidelity wireframes, with common editing commands and interface elements in its editor. Its stated desktop-only availability is important to consider when choosing it.

Quickmock may suit people who want a free, open-source way to sketch low-fidelity interface concepts. Organizations can also request quotes for custom component libraries.

Quickmock is a free, open-source workspace for turning early interface ideas into low-fidelity wireframes. It is best for individuals, developers, and organizations that want a deliberately simple sketching tool, especially in a VS Code workflow. The trade-off is a desktop-only product, which makes it a poor match for teams that need an unrestricted browser or mobile process.

Overview

Quickmock keeps its scope on rough interface concepts rather than attempting to cover an entire product-design process. Its building blocks include pages, device frames, UI components, shapes, text components, and other low-wireframe elements. That concentration is useful when the goal is to communicate structure quickly, but it will not suit readers seeking a more expansive visual-design environment.

The project is free and open source under an MIT license. That removes subscription cost and gives technically minded teams a permissive licensing basis for using the software. The project also accepts bug reports and feature requests through GitHub Issues, providing a public route for feedback rather than a conventional paid support tier.

Key features

The editor includes the everyday commands needed to iterate on a sketch: new, open, save, export, undo, redo, copy, paste, delete, zoom, and settings. In practice, that covers the complete loop from starting a mockup through revising and sharing it, without adding heavyweight workflow requirements. Users who need advanced production design, however, should look to a broader tool.

Quickmock's VS Code extension adds a custom editor for .qm files and configures an MCP server for AI tools. This is the clearest reason for developers to choose it: wireframes can sit alongside a code-oriented workspace and connect to AI tooling. Organizations can request custom low-fidelity component libraries by email, with quotes provided for that tailored work; it is a bespoke service rather than an included self-serve feature.

The project identifies React, React Konva, TypeScript, HTML, CSS, SVG, Vite, and Vitest in its technology stack. That may help engineering teams evaluate how well the project aligns with their own ecosystem, but it does not change Quickmock's intentionally narrow wireframing role.

Pricing

The Free plan costs nothing and includes the free, open-source wireframing tool. There are no paid plan levels or stated usage quotas attached to this entry. It is the obvious choice for solo sketching, experimentation, and teams comfortable adopting an open-source desktop tool. Custom component libraries are quoted separately by email, so organizations needing that service should budget for a tailored engagement rather than assume it is part of the free plan.

Platforms

Quickmock is recorded across Android, API, extension, iOS, Linux, macOS, self-hosted, web, and Windows categories, while the homepage says it is now only available on desktop. That desktop-only statement is the practical constraint: choose Quickmock for a desktop-centered setup, not for a workflow that depends on phones or unrestricted browser access.

Who it's for

Developers who want wireframes near VS Code, open-source users, and teams making quick, low-fidelity ideas are the strongest audience. The focused component set and basic editing commands keep early communication direct. It is less appropriate for users who need a polished, multi-stage design system, a mobile-first process, or a product whose primary work happens entirely in a browser.

Pros and cons

• Pro: Free and MIT-licensed, making experimentation and internal adoption straightforward.
• Pro: The VS Code editor and MCP server connect wireframing with a developer-focused workflow.
• Pro: Core commands cover creating, revising, and exporting low-fidelity sketches.
• Con: Desktop-only availability limits teams that require mobile or web-first access.
• Con: The intentionally low-fidelity scope is not a substitute for a broader design-production suite.
• Con: Organization-specific component libraries require a separate quote.

Alternatives

Readers comparing products can start with Wireframing Software for a wider category view.

Fluid UI is the better choice when you want a freemium product with a free trial and broad Android, iOS, Linux, macOS, web, and Windows coverage.

Choose Justinmind instead if a freemium plan with one project, unlimited screens and viewers, and interactive input forms is more useful than Quickmock's focused editor.

Mockplus suits teams that need a free-forever basic tier with 10 users, 10 active projects, unlimited designs, three project folders, and one administrator.

Grapholite is an alternative for buyers willing to pay a perpetual license rather than use a free open-source tool.

Mokkup.ai is another web-based freemium option.

Visily is worth considering when AI credits and AI-assisted design are central to the workflow.

Banani offers a web freemium model built around monthly and daily credit allowances.

Draftium is an alternative for prototype work with a free-forever tier capped at three prototypes.

Verdict

Choose Quickmock if you want a no-cost, open-source way to shape low-fidelity ideas on a desktop, particularly with VS Code and AI tools in the same workflow. Look elsewhere if mobile access, a browser-first process, or a deeper design and prototyping system matters more than that focused simplicity.
