Image Playground integration: reader toolbar button ("Create Image
with Image Playground") opens the system generator, seeded with the
current text selection when there is one. Result uploads through the
same attachments.create/upload flow as everything else and inserts
Outline's own stable  reference
at the caret, via a new generic TextInsertionRequest/
pendingTextInsertion mechanism on NativeTextViewWrapper (nothing
previously let an embedder insert text into the editor from outside
at all).
Along the way, found and fixed a real pre-existing gap: standard
 Markdown images never rendered anywhere in the app -
services.images was never wired to anything but the no-op default, so
every such image silently fell back to dimmed raw source. Added
OutlineAPIClient.fetchAuthenticatedFile (Bearer-authed GET, for
attachments.redirect and similar) and OutlineImageProvider, a real
EmbeddedImageProvider backed by it, wired into every render surface
(reader, split-view preview, present sheet, collection overview).
Also fixes two Split View bugs surfaced while building this: the
raw-source pane was a plain SwiftUI TextEditor with no selection or
insertion hook, so the Image Playground button couldn't see a
highlighted selection there and generated images had nowhere to land;
replaced it with NativeTextViewWrapper in rawSourceMode (same engine,
no styling overhead, but now selection/insertion work like every
other pane). Also moved onSelectedTextChange's firing point earlier
in the delegate, since it was previously placed after the
rawSourceMode early-return and so could never fire for a raw-mode
editor at all. And images sized off a possibly-not-yet-settled text
container width during Split View's frequent per-keystroke rebuilds,
sticking at the wrong size until the document was reopened - now
re-measured once more a tick after layout settles.
Also reorganizes Settings: Command Palette and its full-workspace-
search toggle move out of Editor into a new Navigation section, since
they're about finding things, not about how documents are edited.
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.
License
Outpost itself is licensed under the Business Source License 1.1 — the same license family Outline's own server uses, for the same reason. In short: free to read, self-host, and modify for personal or non-commercial use; not free to repackage as a competing hosted product or to distribute under a name/branding that claims official or affiliated status. It converts automatically to Apache License 2.0 on the change date stated in LICENSE. "Outpost" and its logo are trademarks of the project — see the license's trademark notice.
This project is a client only — it does not include, vendor, or redistribute any of Outline's own (also BSL 1.1 licensed) server source.
Credits
The native markdown editor is built on swift-markdown-engine by Luca Chen, licensed under Apache License 2.0. It's vendored directly in Vendor/swift-markdown-engine (see its LICENSE); local fixes made in that copy haven't been upstreamed yet.
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.
