NpmStars

NpmStars is a free, web-based tool by BasicUtils that combines npm download trends and GitHub star history into a single unified platform for tracking open-source package popularity.

What is NpmStars?

NpmStars is a unified analytics platform that takes npm package names as input and produces synchronized line charts of npm downloads over time and GitHub star growth, plus a metrics table with size, version, and links. It runs entirely in the browser and is developed by BasicUtils.

Key Features

• Unified Graphs — Side-by-side line charts for npm downloads and GitHub stars with synchronized time ranges (daily, weekly, monthly, yearly).
• Multi-package Comparison — Compare up to 5 packages simultaneously with autocomplete search; optimized for 5 at a time.
• Shareable Insights — Generate shareable images and direct links for all charts; no login required.
• Metrics Dashboard — Per-package table showing total downloads, size (kB), gzip size, version, and direct links to View on NPM, View Repository, and View on Bundlephobia.
• GitHub Token Support — Optional personal access token (no scopes required) raises the API rate limit from 60 to 5,000 requests/hour.
• Modern Tech Stack — Built with Next.js, TypeScript, Recharts, React, and TailwindCSS for fast, responsive performance on desktop and mobile.
• Free and No Account — Start typing package names immediately; no sign-up or subscription.

Who is it for?

• Open-source maintainers tracking download trends and star growth to measure project adoption and community engagement.
• Developers evaluating packages for integration by comparing popularity and activity without switching between npmtrends and star-history.
• Technical analysts researching ecosystem trends using dual-metric insights (downloads vs. stars) for reports or strategy.

What can you do with NpmStars?

• Compare npm download trends of multiple open-source packages to see usage over the last year or custom time range.
• Track GitHub star growth to gauge community interest and long-term viability.
• Visualize the relationship between downloads and stars directly on the same page to understand if high usage aligns with high engagement.
• Share visual comparisons as shareable image URLs or direct links; embed graphs in blog posts or documentation.

How does NpmStars work?

Type a package name into the search bar (autocomplete suggests valid packages). The tool fetches real-time data from npm, GitHub, and Bundlephobia. Two synchronized line charts appear for npm downloads and GitHub stars, plus a metrics table with details. You can add more packages to compare side by side.

Pricing

NpmStars is completely free to use with no hidden tiers or account requirements.
