Best VPS for a Forum Community

Forums vary wildly in resource needs. A lightweight Flarum board is tiny; a full Discourse install is a real application.

Flarum vs Discourse

• Flarum — PHP + SQLite/MySQL; runs in 1 GB.
• Discourse — official Docker install wants 2 GB RAM minimum, plus Postgres and Redis.

The pick: RackNerd 4GB

For Discourse, RackNerd’s 4 GB plan at $59.99/yr meets the recommended minimum with full root and a dedicated IPv4. For Flarum or phpBB, the 2 GB plan at $35.99/yr is plenty.

Set up Discourse

git clone https://github.com/discourse/discourse_docker.git
cd discourse_docker && ./discourse-setup

The installer asks for your domain and email, then wires up Postgres, Redis, and Let’s Encrypt for you.

• Email deliverability — a forum needs reliable transactional mail for signups and notifications.
• Moderation tools — enable rate limiting and spam protection early.
• Backups — Discourse has a built-in backup command; run it on a schedule.

Bottom line: Flarum or phpBB → 1–2 GB; Discourse → 4 GB. Match the software, not just the member count.
