Documents and notes decision

Roam Research

A single capable developer can build a useful self-hosted Roam-like for personal use (backlinks, editor, graph) in a multi-week effort using existing open-source patterns; hosted polish, mobile apps, and managed sync are the main things they'd forgo.

Open-source builds that already do this

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Roam Research alternatives, with the arithmetic →

readrule/iamtirediamtired Canvas is a local-first note-taking app built on a spatial workspace that combines an infinite canvas with real Markdown documents, supporting networked thinking through free linking, grouping, and optional AI-assisted writing.Open on GitHub hafid-firman-febrian/mesh-draftMeshDraft is a local-first mobile note-taking app for knowledge workers, built with Flutter and backed entirely by an on-device SQLite database. Notes are linked by hand, and the whole note base renders as a living, physics-driven graph you can pan, zoom, and drag.Open on GitHub

What a replacement has to do

Create and edit interlinked blocks/pages, automatically record/display backlinks, and render a navigable graph of linked notes.

What it still won’t have

Hosted sync network and multi-device managed backup
Polished UX and performance tuning at scale
Mobile-first native apps and app-store distribution
Proprietary collaboration features and hosted integrations
Commercial support and official templates/plugins

What remains hard

Product polish and ongoing maintenance

Runnable build prompt

Not run yet

Build a self-hosted Roam-like note app using Node.js + Express, React (or Svelte) frontend, SQLite (or Postgres) for storage, and WebSocket for realtime sync. In scope: block-level Markdown editor with per-block IDs, create/edit/delete blocks, backlink indexing on save, paginated/full-text search, interactive D3-based graph view, simple email/password auth, and a JSON REST + WebSocket API. Out of scope: federated multi-user scaling, mobile native apps, advanced permissions, and paid billing. Include input validation, error handling, and automated tests for API endpoints and core editor/backlink flows. Provide Dockerfiles and a minimal deployment script targeting a single VPS.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
