Auto-generate Java project README, class hierarchy diagrams, and API reference from your source code. Codec8 handles Maven, Gradle, and Spring projects alike.
Java projects have Javadoc, but most teams either skip writing tags entirely or write them inconsistently. The result is documentation that covers 20% of the public API and misleads readers about the rest.
Tailored documentation features for Java codebases
Reads existing Javadoc tags (@param, @return, @throws) and infers missing documentation from code
Generates Maven pom.xml and Gradle dependency snippets for easy integration
Produces UML-style class and interface hierarchy diagrams as Mermaid charts
Documents Spring annotations (@RestController, @Service, @Entity) into human-readable endpoint and model reference

These well-known projects are perfect candidates for Codec8
Yes. Codec8 reads pom.xml for Maven projects and build.gradle or build.gradle.kts for Gradle projects, generating appropriate dependency and build instructions.
Yes. Codec8 works with any Java version. For older codebases without annotations it relies more heavily on naming conventions, class hierarchies, and any existing Javadoc.
Codec8 reads the parent pom.xml and each module, generating per-module documentation and a top-level project guide explaining what each module does and how they fit together.
