 We've completed the core development of Namingo, including WHOIS, DAS, EPP, RDAP servers, and control panel. The system handles 150,000 domains efficiently (on a VPS with 2 cores, 4GB of RAM, and a 100GB SSD) and has passed basic QA and security tests.
 
+Namingo currently supports Ubuntu 22.04 LTS and Debian 12, accommodating both MariaDB/MySQL databases. We are eagerly inviting volunteers to assist in testing and developing installation manuals for AlmaLinux, Alpine Linux, FreeBSD 14, and Windows, encompassing setups with either MariaDB/MySQL or PostgreSQL databases.
