New Outpost-local Settings → Editor section (not synced to Outline, same as Appearance) with a Split View toggle: raw Markdown source on the left (plain TextEditor, not the rendering engine), the same rich rendering used everywhere else in the app on the right, read-only, live-updating off the same text binding. Fixed a real layout bug before shipping it: the split view was nested inside the page-level ScrollView, which proposes unbounded height to its content, so a minHeight just resolved to exactly that minimum instead of filling the window. Restructured so Split View bypasses the outer scroll entirely (title fixed at top, HSplitView taking every remaining pixel below it) — each pane already scrolls itself, so nesting it inside another unbounded scroll container was fighting itself for height. Normal single-pane reading/editing untouched. Known follow-up, not attempted: scroll position between the two panes isn't synchronized — the editor package exposes no scroll hook, so doing this for real means introspecting its private view hierarchy. Also removed the "Sub-documents" section from the reader per explicit request — the childrenSection view, and the now-unnecessary listDocuments(parentDocumentId:) fetch backing it in the view model.
Outpost
A native Apple ecosystem client for Outline — built for iOS, iPadOS, and macOS from a single SwiftUI codebase, aiming for full editing parity with Outline's web app, including realtime collaborative editing.
Early alpha — macOS only for now. Expect missing features and rough edges. iOS/iPadOS support is planned but not in the current build. See the releases page for changelogs, and open an issue if you hit anything.
Why
Outline's web app is great, but there's no native Apple client with full editing parity. This project connects to a self-hosted Outline instance over its REST API and realtime collaboration socket to provide a proper native experience across the Apple ecosystem.
Requirements
- Xcode 27+ (currently developed against an Xcode 27 beta — this is a hard minimum, not a suggestion)
- macOS 27+. iOS/iPadOS support is planned but not in the current build (see the alpha note above) — same 27+ minimum will apply once it lands
- A self-hosted (or hosted) Outline instance with API access
Setup
- Clone the repo and open the
.xcodeprojin Xcode. - Generate a scoped API key on your Outline instance (Settings → API Keys).
- On first launch, enter your instance URL and API key — these are stored in Keychain, never in app config or source.
Architecture
See CLAUDE.md and docs/ARCHITECTURE.md for the full technical breakdown: REST layer, Yjs/Hocuspocus realtime sync via YSwift, and the ProseMirror-schema-to-native-editor mapping.
Disclaimer
This project is being built to solve a personal problem — I wanted a genuinely good native knowledge-base client for my own self-hosted Outline instance and none of the existing options fit. It's a personal-use tool first, not a polished product with support guarantees.
Parts of this codebase are AI-assisted (built with the help of AI coding tools). Treat that however you like — review, use, fork, or ignore the code accordingly. No warranty of quality, security, or fitness for any particular use is implied beyond what's stated in the license below.

This project is a client only — it does not include, vendor, or redistribute any of Outline's (BSL 1.1 licensed) server source. See LICENSE for this repository's own license.
Privacy
Outpost collects nothing about you — no analytics, no telemetry, no crash reporting of its own, no age or demographic data, nothing. The only thing stored locally is your Outline server URL and API token (in the device Keychain) and, optionally, a local offline cache of what you've viewed. Everything else goes straight from your device to whatever Outline server you configure — there's no backend in between, and the developer has no access to your data or your server.
