Automatic scaling
Every group keeps its minimum of servers online. Crashed servers are replaced, and a group that keeps crashing backs off instead of looping.

One master, as many wrappers as you like. Servers and proxies start where there is room, scale with your players and get template changes within seconds.

Features
Everything a network needs, nothing it does not
rexlCloud takes care of starting, placing, updating and connecting your servers, so you can spend your time on the game.
Smart placement
A server starts on the wrapper with the most free memory that has its templates and Java runtime. Busy CPUs are only used when nothing else fits.
Multi-root, encrypted
One master and as many wrappers on as many machines as you like. Their connection uses TLS 1.3 with a pinned certificate fingerprint.
Templates in seconds
Global, group and variant templates (e.g. a random map per server). A changed file is on every wrapper about two seconds later.
Paper, Spigot, Velocity, BungeeCord
Pick a version and the cloud downloads it, or builds Spigot with BuildTools. The plugin runs on everything from 1.8.8 to the newest release.
Your own server jar
Groups can run any server.jar, for example a Minestom server. The MinestomBridge connects it to the cloud with three lines of code.
Web panel and REST API
Manage servers, groups, templates, players and wrappers in the browser, with a live console, users and permissions, over HTTPS.
Updates without downtime
Restart or update the master and the network keeps running. With detached servers even wrapper updates leave the servers online.
A real-time Java API
Every console command has an API method. Events, message channels between servers and asynchronous calls, all with Javadoc.
How it works
One master, many wrappers
The master holds the configuration, the templates and the database and decides where servers run. Wrappers on your machines start the servers and report back. Players only ever see the proxy.
- 1
Master
Groups, templates, database, REST API. Decides what runs where.
- 2
Wrappers
One per machine. Start servers, sync templates, report memory and CPU.
- 3
Servers & proxies
Get the cloud plugin automatically and talk to the API in real time.
Web panel
Your network in the browser
Install the optional RestModule and log in at web.rexlcloud.de, or host the panel yourself. Everything the console can do, with a live view of servers, players and resources.
For developers
Build on top of the cloud
Write modules that run inside the master, plugins for Paper, Spigot, Velocity and BungeeCord, or connect your own Minestom server. Every API is published with full Javadoc.
MyPlugin.java

.thenCompose(group -> cloud.startServer(group, 2))
.thenAccept(servers -> log(servers.length + " started"));
