A wiki/knowledge base on ATProto. Sign in with your Bluesky account, create public or private wikis, write in plain markdown with [[wikilinks]]. Your data lives on your PDS — it outlives the app.

Obsidian-compatible. Non-dev friendly. Simple by design.

Getting Started#

bun install
bun run dev

Server starts at http://localhost:3000. The database auto-seeds with sample wikis and notes on first run.

Architecture#

Philosophy#

• One account, many apps — ATProto identity as passport
• Data outlives the app — records on PDSes forever
• Self-hostable — clone, set env vars, run your own appview
• Flat notes, not folders — fuzzy finder over hierarchy
• Simple — minimal config, no unnecessary features in v1
• Honest — transparent about what's stored where and why

Three layers#

PDSes — the permanent record. Each contributor writes their own revision records to their own PDS via OAuth. No one writes to anyone else's PDS.

AppView — our server. Ingests records from the firehose, materializes current state of each wiki, enforces access control, serves all reads.

App PDS — our own PDS instance for private wikis only. Private wiki records live here instead of users' public PDSes. Users still authenticate with their Bluesky identity.

Data model#

Portable vs. appview-local data#

Protocol data (on PDSes, visible via firehose) is portable across appviews. Local data is each appview's value-add.
