Layer 5 · self-hosting reality check
What it actually takes to self-host Logseq
The docs say 512 MB. In practice you want 2 GB with a large graph open. Here is the honest version — real requirements, real monthly cost, what you will be maintaining, and the one thing that catches people out.
Usually reached from Notion alternatives, where Logseq is one of the picks.
Wondering whether you need to at all? Is Notion free? — what the free tier actually allows, and where the wall is.
| RAM — documented minimum | 512 MB |
|---|---|
| RAM — what it really needs | 2 GB with a large graph open |
| CPU | Any modern CPU |
| Disk | Graph size; Markdown files are tiny |
| Monthly cost | $0 — it runs on the machine you already own |
| Setup time | 20 minutes |
| How you install it | Desktop app pointed at a local folder; sync with Git or Syncthing |
| Ongoing maintenance | None beyond updates. |
| Where it stops scaling | Tens of thousands of blocks. Very large graphs slow the initial index. |
The thing that catches people out
Logseq is outline-first — every line is a block and the daily journal is the default entry point. People who want pages and databases find themselves fighting the structure constantly, because the outliner is not a view you can turn off. It rewards the people it suits enormously and frustrates everyone else, and you know which you are within about a week.
When not to self-host Logseq
You think in documents and tables rather than bullets. Obsidian is closer to documents; AppFlowy is closer to Notion's databases.
Every guide here carries this section. A site that only ever tells you to self-host is selling something — the useful answer is sometimes no.
