Grype
Cybersecurity
Vulnerability scanner for container images and filesystems
- From
- Free
- Free plan
- Yes
The short version
- Each has a real cost: ESLint slow performance on large codebases compared to newer tools like Oxlint and Biome; Grype depends on public vulnerability databases, so coverage and false positives vary by ecosystem
- Prices and features above were last checked on 29 August 2026.
Where they differ
Only the attributes on which ESLint and Grype actually diverge.
Identical on both: starting price (Free), free tier (Yes), user rating (Not yet rated).

What people use each for

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
ESLint
- Slow performance on large codebases compared to newer tools like Oxlint and Biome
- Complexity in configuration from scratch, particularly for TypeScript support
- Limited built-in TypeScript support, requiring separate parsers and coordination with new TypeScript features
Grype
- Depends on public vulnerability databases, so coverage and false positives vary by ecosystem
- No triage, exception tracking or reporting UI — that is Anchore’s commercial product
- Overlaps heavily with Trivy, and most teams pick one rather than running both

Questions people ask
- Is ESLint or Grype better?
- Neither clearly leads. ESLint starts at Free and Grype at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, ESLint or Grype?
- ESLint starts at Free and Grype at Free.
- Does ESLint or Grype run on more platforms?
- ESLint runs on Browser-based JavaScript, Node.js, Any JavaScript environment. Grype runs on Linux, macOS, Windows, Docker.

- Both have a free tier, so you can try either at no cost before committing.
- What is ESLint best used for?
- ESLint is most often used for statically analysing javascript and jsx to find problems before runtime, automatically fixing issues with syntax-aware rewrites, enforcing a consistent code style across a team, running as a ci step to block non-conforming code. Of those, statically analysing javascript and jsx to find problems before runtime and automatically fixing issues with syntax-aware rewrites are not what Grype is typically brought in for.
- What can ESLint do that Grype cannot?
- Grype covers Image and filesystem scanning, SBOM-driven, Wide ecosystem coverage, Pipeline friendly.
Answered from the vendors’ own pages
ESLint: Does ESLint automatically fix code issues?
Many problems ESLint finds can be automatically fixed via the --fix flag. ESLint fixes are syntax-aware so you won't experience errors introduced by traditional find-and-replace algorithms.
SourceGrype: Is Grype free?
Yes, open source from Anchore. Anchore Enterprise is the paid platform around it.
ESLint: How much does ESLint cost?
ESLint is completely free and open-source software maintained by the OpenJS Foundation. The project accepts voluntary donations from sponsors.
SourceGrype: What is the difference between Grype and Syft?
Syft generates the software bill of materials; Grype matches that inventory against vulnerability data. They are designed to be used together.
ESLint: Can I write custom ESLint rules?
Yes. You can develop custom rules that work alongside built-in functionality through ESLint's plugin system, allowing complete customization for your project needs.
SourceGrype: Grype or Trivy?
They cover similar ground. Trivy is broader out of the box, including misconfiguration and secret scanning; Grype pairs more cleanly with an SBOM-first workflow.
