Snyk Advisor Alternative — Free Browser-Based Dependency Scanner

Snyk Advisor shut down in January 2026. PackageFix is the free, browser-based replacement — paste your manifest, get a fixed version back. No signup, no CLI, no GitHub connection.

What Snyk Advisor Did

Snyk Advisor provided package health scores, CVE lists, and maintenance status for npm and PyPI packages — all in a browser with no login required. It was the go-to tool for developers who wanted a quick dependency health check without setting up a full pipeline.

PackageFix was built to fill this gap — and goes further by generating the fixed manifest file.

Frequently Asked Questions

What happened to Snyk Advisor?

Snyk Advisor shut down in January 2026. The product provided browser-based package health scores and CVE checking without a CLI or GitHub connection. Snyk did not announce a direct replacement — users were directed to the main Snyk platform which requires GitHub access.

What is the best Snyk Advisor alternative?

PackageFix is the closest browser-based alternative. Paste your manifest file (package.json, requirements.txt, Gemfile, composer.json, go.mod, Cargo.toml, or pom.xml) and get back a CVE table, CISA KEV flags, and a downloadable fixed manifest. No signup, no CLI, no GitHub connection.

Does PackageFix require a GitHub connection like Snyk?

No. PackageFix runs entirely in your browser. Paste any manifest file directly — no GitHub, no account, no CLI install. Your files never leave your device.

Does PackageFix support the same ecosystems as Snyk Advisor?

PackageFix supports 7 ecosystems: npm, PyPI (Python), Ruby (Gemfile), PHP (Composer), Go (go.mod), Rust (Cargo.toml), and Java/Maven (pom.xml). Snyk Advisor only covered npm and PyPI before shutting down.

Is PackageFix free like Snyk Advisor was?

Yes — PackageFix is completely free, MIT licensed, and open source. No paid tier, no credit card, no feature limits.

What does PackageFix have that Snyk Advisor didn't?

PackageFix generates the fixed manifest file to download — Snyk Advisor was a checker only. PackageFix also adds CISA KEV flags, supply chain attack detection (Glassworm/Unicode injection, typosquatting, zombie packages), and supports 5 more ecosystems.
