How many packages can I compare at once?

You can compare two or more packages simultaneously by listing their names as arguments in the comparison command.

Is the comparison data real-time?

Results are cached for 6 hours to ensure performance. However, you can use the --no-cache flag to bypass the cache and fetch the most recent data directly from the NPMS.io API.

What metrics are used to compare npm packages?

The skill uses NPMS.io scores including Overall, Quality, Popularity, and Maintenance, alongside GitHub stars, forks, open issues, and monthly npm download counts.

Why should I use NPMS scores instead of just checking npm downloads?

While downloads indicate popularity, NPMS scores provide a holistic view of a package's health by algorithmically analyzing code quality, maintenance frequency, and project documentation.

Developer Tools

Compares multiple npm packages side-by-side using NPMS.io quality metrics to help developers select the best dependencies.

About

NPMS Package Comparison is a specialized Claude Code skill that streamlines the evaluation of npm libraries by providing objective, side-by-side metrics from NPMS.io. It enables developers to compare overall quality, popularity, and maintenance scores, along with GitHub statistics like stars and issues, and monthly npm download counts. By surfacing these data-driven insights directly within the coding environment, it helps engineering teams make informed decisions about project dependencies, evaluate modern alternatives to legacy libraries, and ensure long-term project health based on comprehensive third-party analysis.

Key Features

Real-time GitHub statistics including stars, forks, and issues
2 GitHub stars
Detailed scoring for Quality, Popularity, and Maintenance
Smart caching mechanism for fast, efficient API responses
Side-by-side metric comparison of multiple npm packages
Monthly npm download tracking for adoption analysis

Use Cases

Auditing project dependencies for maintenance health and security risks
Evaluating major framework alternatives like React, Vue, and Angular
Choosing between similar utility libraries such as Axios vs. Got vs. Node-fetch
