About Yona

Yona is a self-installed project collaboration platform that combines an issue tracker, discussion boards and code review with built-in source repositories. It supports Git, SVN and Mercurial, and the maintainers emphasize that an installable platform avoids worries about service shutdowns or data lock-in.

Issues are project-based and flexible, with moves between projects, subtasks, change history and templates. Code review works on individual code blocks with review threads and scores, and groups let you manage issues, posts, projects and members across an organization. Security options include LDAP, OAuth2 social login, two-factor authentication with TOTP and passkeys, SSH keys, GPG commit signature checks and deploy keys. Audit logs track important events.

This repository is a rewrite of the original Java and Play Framework application in Kotlin with Spring Boot, JPA and Thymeleaf on JDK 21, with the goal of keeping screens and behavior close to the legacy version. It works with MariaDB, PostgreSQL, MySQL, SQL Server, CUBRID or embedded H2, adds scoped API tokens, an OAuth2 authorization server and a built-in MCP server for AI agents, and is licensed under Apache-2.0.
