RunOnVPS sizing suggestion
Suggested VPS tier
2 GB RAM tier
This is our sizing suggestion, derived from Lemmy’s recommended RAM of 2GB. It is not an official requirement and it does not guarantee that every workload, plug-in set or media library will fit comfortably.

Important notes
Stars approx. from GitHub API snapshot (stargazers_count 14283); license AGPL-3.0 per repo/API, checked 2026-10-24. Official Docker install docs state no hardware specs — 官方未标明 RAM/CPU/磁盘，均为基于官方 docker-compose（Lemmy+lemmy-ui+pictrs+PostgreSQL）默认部署的估算，磁盘随 pictrs 图片存储增长.
