Mainline Developer Dashboard

Overview

Mainline is a source-hosting dashboard modeled on GitHub. The home page has a KPI strip, a contribution heatmap covering four years, a language breakdown, drag-and-drop pinned repositories and a monthly activity timeline.

Repositories open to a detail page with tabs, a file tree, README and an About sidebar. Pull request and issue queues show labels, CI status and priority, and there are notification, new repository and settings pages too.

Mainline is one of 20 templates in the Shadcn Admin Dashboard Kit, sold as a single $129 download. It's built with Next.js 16, React 19, Tailwind CSS v4 and shadcn/ui, and runs on mock data you can replace with a real API.
