Know if your dependencies are healthy.
We're on a mission to help developers avoid abandoned dependencies and make informed decisions about package health before they become blockers.
Why Check exists
The Lightbulb Moment
"What if we could spot abandoned dependencies before they become blockers?"
As engineers ourselves, we've all been there: you add a dependency to your project, it works great initially, but months later you discover it hasn't been updated in years. Security vulnerabilities pile up, compatibility issues emerge, and suddenly you're stuck with tech debt that slows down your entire team.
We realised that while tools like Snyk and Dependabot focus on security vulnerabilities, there was no simple way to assess the ongoing health and maintenance viability of dependencies. Most developers only discover a package is abandoned when it's too late; when they need a critical update or fix that will never come.
So we built Check - a dependency health dashboard that analyses community activity, maintenance signals, and release cadence to give you instant health scores. Upload your package.json, requirements.txt, or Cargo.toml and get actionable insights to avoid risky dependencies before they become blockers.
What drives us forward
These principles guide every decision we make and every feature we build.
Dependency-First
We believe dependencies are critical infrastructure. Understanding their health, maintenance status, and community activity helps you make better decisions.
Prevent Tech Debt
Spot abandoned dependencies and risky packages early. Get instant health scores so you can make informed decisions before committing to a library.
Simple & Fast
No complex integrations needed. Just upload your manifest file and get instant health scores. Built for developers who want answers fast, not more tools to configure.
Developer Experience First
Built by engineers, for engineers. Every feature is designed to help you ship faster by avoiding dependencies that will slow you down later.
From idea to reality
Here's how we've grown from a simple idea to a platform trusted by engineering teams worldwide.
The initial idea for Check was born from our own frustrations dealing with abandoned dependencies and stale packages that caused production issues.
Started building the MVP with a focus on dependency health scoring and helping developers avoid risky packages before they become blockers.
