Tauri desktop & macOS native.

/ 01Two clients, one format

The Fieldbook format is the contract. Both clients read and write the same .fieldbook file, with the same integrity model, the same oplog, the same audit log. You can open a file in one, close it, and open it in the other — sync is implicit because the file is the source of truth.

/ 02Tauri desktop

The default. Tauri 2 wraps a React + TypeScript frontend with a Rust backend that talks directly to fieldbook-core. Available on macOS, Windows, and Linux.

Install

• macOS — .dmg from the download page; drag to Applications
• Windows — .msi installer; signed with EV certificate
• Linux — .AppImage (recommended), .deb, .rpm

System requirements

• macOS 12+ · Windows 10 21H2+ · any modern Linux with glibc 2.31+
• 2 GB RAM minimum (4 GB recommended for > 100k row files)
• WebView2 (Windows) — bundled if missing

/ 03macOS native

For teams that want a native macOS experience, the SwiftUI client offers full feature parity plus a few macOS-only views (Lineage, Relationships, native Spotlight integration). It calls into fieldbook-core via UniFFI-generated Swift bindings.

Distribution

• Direct download — notarised .dmg from the download page
• TestFlight — request invite from your tenant admin
• MDM — pkg available for Jamf, Kandji, Intune deployment

/ 04First-launch onboarding

Both clients run the same onboarding on first launch:

1. Identity

   Sign in with the configured IdP (Google Workspace, Microsoft Entra, Okta, Auth0). For self-host, point to your own OIDC endpoint.

2. Encryption preference

   Default to "encrypt new files" with a strong password generator. You can switch off per-file at create time.

3. Sample data

   Optional: load "Project Helios" — a demo CDD scenario with 5 entities, 25 requirements, 22 documents.

4. Engine connection

   If a Redline or Atrium engine is configured, the client tests it and surfaces a green/amber indicator. Skippable.

/ 05Client differences

Feature parity is the goal; deltas are documented per release in CHANGELOG.md.
