Quickmock

Quickmock is a free, open-source tool for sketching low-fidelity wireframes, aimed at people who need to turn interface ideas into rough mocks quickly. Its core editing commands and VS Code extension are useful, but its desktop-only availability may rule it out for web-first work.

Overview

Quickmock focuses on early-stage wireframes rather than a broad interface-design workflow. That makes it a reasonable fit for outlining screens and sharing rough concepts, but less suitable when a project needs capabilities beyond low-fidelity mockups.

The homepage says Quickmock is now available only on desktop, while its platform is identified as web. That distinction matters: check whether the desktop-only notice matches the way you intend to use it before making it part of a workflow.

Key features

The editor combines pages, device frames, UI components, shapes, text, and low-wireframe elements. These building blocks cover the basic work of arranging rough screens without implying a full design suite.

Commands include creating, opening, saving, and exporting files, as well as undo, redo, copy, paste, delete, zoom, and settings. That gives users the essentials for iterating on a sketch and exporting it, though the tool’s stated focus remains low-fidelity work.

The VS Code extension adds a custom editor for .qm files and configures an MCP server for AI tools. This makes Quickmock more relevant to developers who want wireframes in a VS Code-oriented workflow than to users seeking a standalone, expansive design environment.

Organizations can request custom low-fidelity component libraries by email, with quotes available. This could suit teams that want organization-specific components, but it is a bespoke option rather than a published self-serve plan.

Quick Mock is open source under an MIT license, and the project welcomes bug reports and feature requests through GitHub Issues. Its technology stack includes React, React Konva, TypeScript, HTML, CSS, SVG, Vite, and Vitest, which may be relevant to teams assessing the project technically.

Pricing

The Free plan costs nothing and is described as a free, open-source wireframing tool available only on desktop. There are no paid tiers or seat and usage caps in the plan details. For individuals and teams willing to work within its low-fidelity scope, the lack of a subscription cost is a clear advantage; organizations seeking custom component libraries should expect quotes by email.

Platforms

Quickmock’s platform is web, but its homepage says it is now only available on desktop. The VS Code extension provides another route for working with .qm files. Readers who need dependable mobile access should consider another option rather than assume that a web platform label means browser availability across devices.

Who it's for

Quickmock is best suited to people who want a free, open-source way to shape low-fidelity interface ideas, especially developers interested in editing .qm files through VS Code. It is a weaker fit for users who need a confirmed browser-based workflow or a tool for more than rough wireframes.

Pros and cons

• Pros: Free and open source under an MIT license, so the core wireframing tool has no subscription price.
• Pros: Pages, device frames, shapes, text, and UI components cover the basic ingredients of low-fidelity layouts.
• Pros: The VS Code extension supports .qm files and configures an MCP server for AI tools.
• Cons: The desktop-only homepage notice complicates use for anyone expecting a web-based workflow.
• Cons: Its focus is low-fidelity wireframes, making it a poor match for broader design needs.
• Cons: Custom component libraries require an email quote rather than a self-serve purchase.

Verdict

Choose Quickmock if you want a free, open-source tool for low-fidelity wireframes and value the VS Code extension’s support for .qm files. Its focused editor is the main reason to choose it; the desktop-only notice is the main reason to look elsewhere, particularly if you need a reliable web-based workflow.
