IsItStable
A stability-score lookup for npm package versions, backed by GitHub issues and community reactions rather than a database, answering whether it is safe to upgrade to the latest version of a package.
IsItStable gives every tracked npm package version a stability score backed by evidence: referenced GitHub issues, download statistics, and community votes cast as reactions on GitHub issues. Each tracked version has a corresponding issue in the project's repository, and users vote by reacting with a thumbs-up for stable or thumbs-down for unstable; the public website reads scores directly from the GitHub Issues API, with no separate database.
It can be queried from the command line with no install required, or through a JSON API with endpoints for a package's latest verdict, its list of tracked versions, its best-scoring version with an install command, or details for one specific version including referenced issues and stats. A GitHub token environment variable raises the API rate limit during local development. Anyone can request a new package be tracked by opening an issue.
