The modern, self-hostable web UI for LDAP administration.
Manage users, groups & organizational units on any LDAPv3 server — clean, fast, open source.
Nucleo is pre-1.0 and under active development.
Existing LDAP management tools are either outdated,
too complex, or too limited.
Nucleo is built for homelab admins, self-hosters or small organizations who want a
modern, lightweight, and Docker-friendly alternative.
- 🌲 Generic — connects to any LDAPv3-compatible server (OpenLDAP, 389DS, lldap)
- ⚡ Fast & modern — built with Next.js and NestJS, no legacy stack
- 🔒 Secure by default — LDAPS/TLS, JWT auth, full audit log
- 🐳 Self-hostable — Easy to deploy
- 🧩 Adapter-based — clean hexagonal architecture, easy to extend
