DepAudit vs npm audit vs Snyk: Which Catches More?
All three tools scan your dependencies — but they're solving different problems. For teams using AI coding tools, the differences matter more than you might think. Here's an honest breakdown.
The Quick Summary
If you already have a project installed and just want to check for known CVEs, npm audit works fine and it's free. If you need enterprise-grade security with license compliance and a managed dashboard, Snyk is the market leader. But if you're writing code with AI tools — or auditing AI-generated codebases — neither of them covers the threats you actually face.
Both npm audit and Snyk were designed for a world where developers write their own package.json files deliberately. That world is changing fast.

npm audit: Fast, Free, and Limited
npm audit is built into npm and has been the default security check for Node.js projects since 2018. It's fast, requires no setup, and is integrated directly into the standard npm workflow. Running npm install triggers it automatically.
But npm audit has fundamental limitations that make it insufficient for modern AI-assisted development:
It requires installation first
npm audit only works on packages that are already installed. If an AI generates a package.json with a hallucinated or typosquatted package, you have to run npm install — potentially executing malicious postinstall scripts — before npm audit can tell you anything is wrong.
CVE database only
It checks packages against the npm advisory database for known CVEs. It has no awareness of whether a package actually exists, whether it's been abandoned, or whether its name is suspiciously close to a legitimate package.
High false-positive rate
npm audit is notorious for flagging low-severity issues in devDependencies that have no real-world impact, leading many developers to ignore its output entirely — which is dangerous when a real vulnerability appears.
Verdict: Good baseline for production vulnerability checks on established codebases. Not adequate for AI-generated code or pre-install auditing.
Snyk: Enterprise-Grade, But Designed for a Different Era
Snyk is the enterprise standard for dependency security. It offers a richer vulnerability database than npm audit (pulling from NVD, GitHub Advisories, and its own research), automated PR fixes, license compliance checking, and a managed dashboard. For security teams at established companies, it's a strong choice.
But Snyk was built for a world where developers deliberately choose their dependencies. Its core assumption is that your package.json is intentional. It's excellent at detecting vulnerabilities in packages that legitimately exist — but it doesn't help when the package itself is fictional.
No hallucination detection
Snyk doesn't check whether a package exists in the first place. If your AI suggested react-auth-flow, Snyk will simply not find any vulnerabilities for it — because there's nothing to find. The non-existence of the package is itself the problem.
Paid tiers for serious use
Snyk's free tier is limited. Teams that want CI/CD integration, unlimited scans, and full reporting need to pay — which can be a barrier for indie developers and small teams who are most likely to be vibe coding.
Requires setup and auth
Unlike pasting a package.json into a web tool, Snyk requires CLI installation, authentication, and project setup — friction that slows down fast-moving teams.
Verdict: Best-in-class for enterprise vulnerability management and license compliance. Overkill for small teams; misses the AI-specific threat vectors entirely.
DepAudit: Built for the AI Coding Era
DepAudit was designed specifically for the way developers actually write code in 2026: with AI assistance. It starts from the assumption that your package.json might contain packages that were suggested by an AI — and that means the audit needs to start earlier and look for different things.
Pre-install scanning
DepAudit scans your package.json before you install anything. Paste your file or connect your repo, and you'll know which packages are safe to install before any code runs on your machine.
Hallucination detection
We check every package name against the live npm registry. Any package that doesn't exist is immediately flagged — something neither npm audit nor Snyk do.
Typosquatting analysis
DepAudit uses similarity analysis to flag package names that look suspiciously like popular packages — catching both accidental typos and deliberate impersonation attempts.
Abandonment detection
We check the maintenance status of every package — flagging libraries that haven't been updated in over a year, have been deprecated, or show other signs of abandonment.
Which Should You Use?
The tools aren't mutually exclusive. Here's a practical approach based on your situation:
Solo devs / indie hackers
Vibe coding with Cursor, Claude, or Copilot
Growing startups
Mixed AI + manual development
Enterprise teams
Compliance + scale requirements
The Bottom Line
npm audit and Snyk are both valuable tools — but they were built for the previous era of software development, where humans chose every dependency deliberately. In 2026, AI tools are choosing your dependencies for you, and the security implications are different.
If you're using any AI coding tool — from Cursor to Claude to Copilot — you need a pre-install audit that checks whether your packages actually exist, whether their names are suspicious, and whether they're still actively maintained. That's the gap DepAudit was built to fill.
