System Requirements
NotePost (and the other Apps) is tested and officially supported on the following configurations. Other systems may be supported at our discretion, possibly with an additional support fee. The Apps should work on any sane Linux/PHP/MySQL based web server, even if it is not within the requirements shown here.
Server
Minimum Hardware
The Netsyms Apps are very lightweight on server resources. The minimum supported hardware is a $35 Rasperry Pi 3 (1.2 GHz quad-core ARM CPU, 1GB RAM, 100Mbps Ethernet). Cloud VPS servers with as little as 512 MB RAM are fine too.
Software and Operating System
- Server Operating System
- Ubuntu
- Debian
- PHP
- 7.2
- Database
- MySQL 5.7+
- MariaDB 10.0+
- Web Server

Recommended Software
For best performance, security, and ease of administration, we recommend installing the following on your server:
- PHP's opcache (cached compiled PHP code for faster execution)
- Fail2ban (if using SSH or other remote administration methods)
- PHPMyAdmin (web-based MySQL/MariaDB server administration)
- LetsEncrypt (automatic free SSL encryption setup)
Client
The Apps are web-based and built with modern technologies. This means any machine capable of running a standards-compliant, modern, up-to-date web browser will run the Apps just fine.
