Integrate ktlint with Vulnetix. Lint Kotlin code for style violations and formatting issues, then upload SARIF results for centralised tracking.
Install & scan
$ # Download the latest standalone binary curl -sSLO https://github.com/pinterest/ktlint/releases/latest/download/ktlint chmod +x ktlint && sudo mv ktlint /usr/local/bin/ # Or via Homebrew on macOS brew install ktlint $ ktlint --reporter=sarif,output=ktlint.sarif "src/**/*.kt" "**/*.kts"
Run ktlint in CI
Scan on every push and upload the report as a workflow artifact:
- name: Download ktlint
run: |
curl -sSLO https://github.com/pinterest/ktlint/releases/latest/download/ktlint
chmod +x ktlint && sudo mv ktlint /usr/local/bin/
- name: Run ktlint
run: ktlint --reporter=sarif,output=ktlint.sarif
- name: Upload report
uses: actions/upload-artifact@v6
with:
name: ktlint
path: ktlint.sarif
if-no-files-found: warnThen one publish job hands every artifact in the run to Vulnetix, recorded under ktlint's own name and version. Written once per workflow, however many scanners you run:
publish:

if: always() # or one failing scanner suppresses all the others

How Vulnetix compares: better together
Vulnetix does not replace ktlint. Keep running it. Vulnetix sits on top of ktlint (and every other scanner you already own) turning disconnected tool outputs into one prioritised, fixable queue.

What ktlint does well
- Opinionated, zero-config "anti-bikeshedding" enforcement of the Kotlin Coding Conventions and Android Kotlin Style Guide
- Built-in formatter (-F / format) that auto-fixes most violations, eliminating separate formatter setup
- Native SARIF reporter (alongside plain, JSON, Checkstyle, HTML) that plugs directly into GitHub code scanning and CI/CD
- Created at Pinterest and now community-maintained under the ktlint org, with a mature Gradle plugin ecosystem for painless integration
Where Vulnetix adds to it: Vulnetix ingests ktlint's native SARIF output into its consolidated, deduplicated findings queue and does not run Kotlin style linting itself; Vulnetix's SAST engine (built-in rules + Semgrep) addresses code-security defects, not Kotlin formatting. Together, ktlint enforces Kotlin style while Vulnetix layers cross-scanner dedup, exploit-intel prioritisation, reachability and VEX.
No migration, no rip-and-replace. ktlint keeps doing what it does best; Vulnetix adds the orchestration, exploit-intelligence prioritisation and remediation layer built for the way AppSec works today.
Centralise ktlint results in Vulnetix
Upload ktlint SARIF output to the Vulnetix platform to deduplicate findings, prioritise them with EPSS, CISA KEV and Coalition ESS exploit intelligence, and track remediation across every scanner in a single queue.
