TYPO3 Extension Conformance Checker

Evaluate TYPO3 extensions against TYPO3 coding standards, architecture patterns, and best practices.

When to Use

• Extension quality / TER readiness
• Scored conformance reports
• Modernization to v12/v13/v14 (v14.3 LTS is default/gold standard)

Delegation

Testing -> typo3-testing | Docs -> typo3-docs | OpenSSF -> enterprise-readiness

Scope: extensions only. Site/project repos (type: project + Compose) — score with the gold checker typo3-14-gold/tools/conformance.
