RunOnVPS sizing suggestion

Suggested VPS tier

4 GB RAM tier

This is our sizing suggestion, derived from Mastodon’s recommended RAM of 4GB. It is not an official requirement and it does not guarantee that every workload, plug-in set or media library will fit comfortably.

Affiliate link placeholder — no provider selected

This placeholder intentionally has no URL or affiliate ID in the Day 2 build.

Deployment

Docker & GPU

Docker support: Yes

GPU: Not required

Check the source notes below before assuming a GPU, transcoding workload or machine-learning feature is included in the baseline deployment.

Commercial alternative

What it can replace

X (Twitter)

Official prerequisites list only OS (Ubuntu 24.04/Debian 13), domain and SMTP; install docs give software stack (Ruby/PostgreSQL 14+/Redis 7+/Node 24+) — 官方未标明 RAM/CPU/磁盘，均为基于官方 docker-compose（web+streaming+sidekiq+PostgreSQL+Redis）默认部署的估算，磁盘随媒体缓存增长. Repo ships official container image and docker-compose.yml.
