About
About Shadcn Calendar Heatmap
Designed to display temporal data patterns in an intuitive, visually appealing format, this component transforms activity data into color-coded calendar grids that make it easy to identify trends, gaps, and patterns at a glance. The heatmap features a year-view calendar layout with weekly rows showing activity intensity through color gradients, customizable color schemes to match different themes and data types, tooltip displays showing exact values and dates on hover, responsive design that adapts calendar density to screen sizes, TypeScript support ensuring type safety for data inputs, integration with shadcn/ui's theming system for consistent styling, and performance optimizations for rendering large datasets efficiently. Unlike basic heatmap solutions that offer limited customization or poor mobile experiences, this component provides the flexibility and polish expected in modern applications.
Use cases include displaying user contribution history similar to GitHub's activity graph, visualizing fitness or habit tracking data across months or years, showing sales or revenue patterns to identify seasonal trends, tracking content publication frequency for blogs or social media, monitoring system uptime or error rates in DevOps dashboards, and presenting any time-series data where visual pattern recognition is valuable. The component's GitHub-inspired design is immediately familiar to developers while being flexible enough for diverse data visualization needs. Built with TypeScript throughout, it provides excellent developer experience with autocomplete and type checking, making integration smooth and reducing runtime errors.

Frequently asked questions
Everything you need to know before you ship with Shadcn Calendar Heatmap.
The shadcn Calendar Heatmap is a modern, sophisticated alternative to primitive React heatmap libraries, providing a GitHub-style contribution calendar visualization built with Next.js, TypeScript, shadcn/ui components, and Tailwind CSS. It is an open source template in the shadcn.io collection of 215.
Shadcn Calendar Heatmap is made by Gurbaaz27, an independent developer; shadcn.io lists it but did not make it. Gurbaaz27 has 1 template in the collection, and the author's page lists them.
The listing tags Shadcn Calendar Heatmap with Next.js, React and Tailwind. Those are its categories, not a dependency list: the exact packages and versions are in the repository's package.json.
Yes. The Shadcn Calendar Heatmap page embeds its live demo from shadcn-calendar-heatmap.vercel.app, and links to it so you can open the real deployment before you clone.
The Shadcn Calendar Heatmap listing was last updated on October 8, 2025. That date is the listing's, not the repository's: check the repository's commits for recent activity.
Clone the repository (git clone https://github.com/gurbaaz27/shadcn-calendar-heatmap), then follow the README. The Shadcn Calendar Heatmap page shows the usual steps and a terminal block with the commands to copy.
Install dependencies with npm install or pnpm install, then run npm run dev. The README in the Shadcn Calendar Heatmap repository says which package manager and environment variables it needs.
No. Shadcn Calendar Heatmap is cloned from its own GitHub repository, so shadcn.io isn't involved. Browsing the page and its live demo need no account either; Pro adds the premium templates, the blocks and the MCP server.
Shadcn Calendar Heatmap is tagged Next.js, so it deploys wherever a Next.js app does, such as Vercel, a Node.js server or a container. Its README may add steps for its own services.
The Shadcn Calendar Heatmap listing doesn't record a license. Check the LICENSE file in its repository (https://github.com/gurbaaz27/shadcn-calendar-heatmap), and ask the author if there isn't one.
That depends on Shadcn Calendar Heatmap's license in its repository, which shadcn.io does not set. Read the LICENSE file before you use it in a client or paid project, and ask the author if it is unclear.
Attribution follows Shadcn Calendar Heatmap's license. Many permissive licenses ask you to keep the copyright notice and license text in your copy; its LICENSE file says exactly what.
No. The Pro license covers shadcn.io's own Pro code, blocks and premium templates. Shadcn Calendar Heatmap is the author's project, under the terms in its repository.
Gurbaaz27 supports Shadcn Calendar Heatmap, through its GitHub repository: read the docs, open an issue or look for discussions. shadcn.io does not maintain it.
Yes. Once you clone it, Shadcn Calendar Heatmap is your own code: change the theme, add pages and connect your backend. It uses shadcn/ui, so you can also add more components the same way.
Yes. Components are free with a free account and the blocks are in Pro; both are copied into your project with the shadcn CLI. Check that Shadcn Calendar Heatmap uses Tailwind CSS and the shadcn/ui setup (a components.json) before you add them, and pick the base library your project already uses.
Yes, with Pro. The shadcn.io MCP server's search_templates tool finds templates by what they are, and returns each one's repository and live demo, so your editor can set up Shadcn Calendar Heatmap for you. Your files stay on your machine.
The collection has 151 other open source Next.js templates like Shadcn Calendar Heatmap, shown at the foot of its page with the ones sharing most categories first. All of them are at /template/category/nextjs.
