About TrustOSS
What is TrustOSS?
TrustOSS is a free web tool that analyzes the health of open-source GitHub repositories. It scores any public repository from 0 to 100, audits whether its stars are organic, scans for known vulnerabilities, and lets you compare up to four candidate libraries side by side — so you can evaluate a dependency before you install it.
Key features of TrustOSS include:
Health scoring of repositories from 0 to 100
Audit of organic stars
Scanning for known vulnerabilities
Side-by-side comparison of up to four libraries
TrustOSS Features
TrustOSS is a free web tool designed to analyze the health of open-source GitHub repositories. It provides a scoring system for any public repository, ranging from 0 to 100, and conducts audits to determine whether the stars are organic. Additionally, it scans for known vulnerabilities and allows users to compare up to four candidate libraries side by side, facilitating informed decisions before installing dependencies.
The health score is calculated based on five weighted dimensions derived from public GitHub data, which include:
Activity (25%) — last push, 90-day commit frequency, release cadence
Maintenance (25%) — median issue close time, open-issue pressure, archived status
Community (20%) — stars, forks, contributors
Documentation (15%) — README, license, contributing guide
Maturity (15%) — project age and release history
