What Modulz does

Modulz was a Dublin, Ireland-based software company founded in January 2019 by Stephen Haney and Colm Tuite that built a code-based visual design tool for designing digital products and design systems. The product was positioned as a visual code editor rather than an illustration tool, enabling teams to author real production components (with Theme tokens, an NPM-published component library, and an auto-generated Styleguide) and export them to Figma, Sketch, Framer, and NPM, effectively collapsing the design-engineering handoff into a single environment. The proprietary platform also emphasized built-in accessibility, including WAI-ARIA-compliant primitives exposed through the related open-source Radix UI library.

The company shipped a small set of open-source projects alongside the core product, most notably Radix (unstyled, accessible UI component primitives) and Stitches (a CSS-in-JS library), which gained meaningful developer adoption and were reportedly used in production by companies such as Vercel, CodeSandbox, Linear, and Supabase. Modulz pursued a product-led, community-driven go-to-market: it raised $36,000 via Kickstarter in November 2018 from 394 backers for early access, closed a $4.2M seed round in March 2020 led by LocalGlobe and Frontline with high-signal angels, and grew to a 6,500+ person waitlist by May 2021 while distributing access through monthly invite drops during its private alpha and beta phases. No public pricing or recurring revenue model was ever disclosed, and the product remained in private beta.

In June 2022, Modulz was acquired by WorkOS, with the founding team joining WorkOS to help ship enterprise features and the Radix project transferring to WorkOS ownership. The Modulz product was sunset on July 1, 2022 after the company concluded it had not achieved product-market fit; Stitches continued to be maintained for existing users.

Core offering

Modulz was a code-based visual design tool optimized for designing digital products and design systems. It allowed teams to design, prototype, and handoff production-ready code (CSS, JSX, NPM packages) using real components rather than static illustrations, with integrated publishing of themes, component libraries, and auto-generated styleguides. The company also produced related open-source projects Radix (UI component primitives) and Stitches (CSS-in-JS library).

Product overview

Modulz was a code-based design tool for designing and prototyping with real components, marketed as a visual code editor for digital products and design systems. The product was a single unified offering that enabled design teams to create themes (reusable tokens), components (production-ready library), styleguides (auto-generated with examples and code snippets), and export to Sketch, Figma, Framer, and NPM. Modulz shipped with related open-source projects Radix (UI component library) and Stitches (CSS-in-JS library). The company was acquired by WorkOS in June 2022 and Modulz was sunset on July 1, 2022.

Products and services

• Modulz A code-based visual design tool for designing and prototyping with real components, targeted at design and engineering teams building digital products and design systems. Enabled design, development, documentation, and deployment of a complete design system in one environment with code export to CSS, JSX, and NPM. Sunset on July 1, 2022 following WorkOS acquisition.
• Radix Open-source, unstyled, accessible UI component primitives for building design systems, with built-in accessibility including screen reader support and keyboard navigation. Used in production by Vercel, CodeSandbox, Linear, Supabase, and WorkOS. Transferred to WorkOS upon acquisition.
• Stitches Runtime CSS-in-JS library for styling web applications. Largely feature-complete; continues to be supported by WorkOS for existing and new users.

Direct peers

• Plasmic: Visual builder that lets teams design and ship production React components, with native design-system integration. Comparable target customer (design + engineering teams) and code-output approach.
• Anima: Design-to-code tool that converts Figma designs into React, Vue, or HTML code with responsive components. Directly comparable design-to-code workflow and developer-handoff focus.
• Webflow: Visual web design platform that outputs production-ready HTML/CSS/JS without manual coding. Most directly comparable to Modulz's vision of bridging design and code, with a much larger team and established SaaS business model.
• Framer: Design and prototyping tool that produces real React/CSS components and supports publishing production websites. Closest peer in terms of design-to-code output philosophy and component-based architecture.
• UXPin: Design tool with code-backed components, design-system merging, and React component generation. Comparable product positioning around component-driven design and code output for product teams.
• Builder.io: Visual design-to-code platform with structured CMS, design system sync, and React/Vue/Angular code output. Directly comparable in producing production-ready components from a visual editor.

Broad incumbents

• Sketch: Established macOS-based design tool with design-system features and developer-handoff integrations. Competes for the same digital product team customers but does not natively output production code.
• Figma: Dominant collaborative design tool with Dev Mode for developer handoff and growing code-generation features. Competes for the same design-system team mindshare but optimized primarily for illustration workflows.

Emerging players

• Storybook: Open-source tool for building and documenting UI components in isolation, widely adopted by design-system teams. Complementary rather than competing, but overlaps significantly in the design-system maintainer persona Modulz targeted.
• Supernova: Design system platform that converts Figma/Sketch tokens into production code for multiple frameworks, with styleguide generation. Closely comparable feature set to Modulz's design-system publishing workflow.
