Discord bot hosting
Discord4J bot hosting
free, always on, no card.
A reactive (Project Reactor) Java library; a good fit if you already write reactive services or Kotlin. On Enzonic the free bot tier gives your Discord4J bot 512 MB RAM and 50% of a CPU core, running 24/7 without sleeping. Small bots idle at about 150 to 300 MB, so that is usually plenty; the Dirt plan ($0.99/mo) adds a second allocation and more headroom.

Where the token goes with Discord4J
Create the bot in the Discord Developer Portal, copy its token, and store it as the DISCORD_TOKEN environment variable in the panel's Startup tab. The code reads it from the environment; nothing secret is in your files.
GatewayDiscordClient client = DiscordClientBuilder.create(System.getenv("DISCORD_TOKEN"))
.build().login().block();Running Discord4J on Enzonic
Things that trip people up when a Discord4J bot moves from a laptop to a server.
- Reactive pipelines need care with blocking calls; keep database access on a bounded scheduler.
- Cap the JVM heap under the plan's RAM.
What the free bot tier includes
512 MB RAM, 50% CPU, 10 GB disk, a live console, SFTP and file manager access, automatic restart when the process exits, and one bot per account. Free bots run on the bot nodes in London, Frankfurt and Singapore (and the United States as capacity allows). Because the bot talks to Discord's gateway, not to your users directly, the node's location barely matters.
Free bot creation is subject to capacity; when the bot nodes are full you join a short queue and the panel emails you when your bot is placed.

Set it up in three steps
- 01
Create the bot server
Choose the Discord4J template (or the Java runtime) and the free tier.
- 02
Upload your code
Drag the project into the file manager or use SFTP. Set DISCORD_TOKEN in the Startup tab; the template runs "Build a shaded jar and upload it" and then "java -jar bot.jar".
- 03
Start and watch the console
The console shows the login. Invite the bot to a test server with the OAuth2 URL from the Developer Portal.
