01 — Authoring

Markdown, turned up.

Live side-by-side preview, tables, tabsets, diagrams, math and syntax highlighting for 180+ languages — all in plain text you own.

A markdown editor with taste

Build on the same foundation as VS Code, a familiar editor with live split preview, syntax-aware autocomplete and highlighting and inline helpers for a great writing experience.

# Pour-over basics

Aim for a **1:16 ratio** — 18 g of

coffee to 290 g of water.

## Method

1. Rinse the filter, discard

2. Bloom with 60 g for 30 s

3. Pour in three even stages

## Dial-in

| Grind | Water | Time |

| --- | --- | --- |

| Medium | 93 °C | 2:45 |

| Fine | 91 °C | 3:20 |

> Taste before you touch the grind.

See the [bean log](/notes/beans).

02 — Organize

Everything in its right place.

A real page tree, a file manager that keeps up, a powerful search and every page in every language — all in one place.

One File Manager for pages and assets

Browse the whole tree, upload assets, create folders, move, rename or delete — pages and files side by side.

A powerful search built-in

PostgreSQL runs the whole stack — handling full-text search, job queue and pub/sub events.

  • PostgreSQL 16+
  • Full-text search
  • Boolean search
  • Filter by tags
  • Search within page contents
  • Auto-completion

Many wikis, one instance

Each site gets its own hostname, theme, locales, auth and storage — from a single deployment.

  • docs.acme.comen · fr
  • handbook.acme.comen
  • wiki.acme.deven · ja

Every page, every language

Locale-aware routing with the ability to link alternate versions of the same page.

  • EN
  • FR
  • IT
  • ZH
  • JA

Two-way Git sync

Content stays plain markdown. Sync with a Git repository or push to local disk, cloud storage (S3, Azure, GCP, etc.) and more.

03 — Governance

Open to all. Yours to govern.

Rules down to the page path, identity from wherever your team already lives, and a full record of who changed what.

Identity, already solved

OIDC (Google, GitHub, etc.), LDAP, SAML auth providers, with group mapping on login.

  • OIDC
  • LDAP
  • SAML 2.0
  • Local Auth

Permissions, per path

Grant, deny and inherit across groups and page rules. What each person sees is never a guess.
