Plain -fuzz -transparent white color-keyed every pixel in the whole image close enough to white by color distance — including an antialiased blend inside the artwork itself (where the light beam meets the window frame), which punched a stray transparent hole there, and still left a faint opaque fringe ring around the outer edge since the binary cutoff didn't fully consume the antialiasing ramp. Redone with a flood fill seeded from a corner pixel instead: only transforms the background region actually connected to that seed (the four corners + thin white border, confirmed contiguous), leaving disconnected internal antialiased pixels untouched. Then eroded the alpha channel by ~2px to consume the remaining boundary ramp cleanly. Verified against both dark and light composited backgrounds, and confirmed the beam/window-frame area is no longer punctured.
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.
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.
Status
Early development. See CLAUDE.md for the current architecture and phased build plan.
- Phase 1 — Auth, browse, search, REST-only editing
- Phase 2 — Realtime collaborative editing (Yjs/Hocuspocus)
- Phase 3 — Offline cache, tables, embeds, comments, macOS polish
Requirements
- Xcode 16+
- iOS 17+ / iPadOS 17+ / macOS 14+
- A self-hosted (or hosted) Outline instance with API access
They will be updated. These are old requirements.
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.
