Shipping Tauri Apps — Webcanvas and the Gnomad Assistant

Cross-platform beta releases for a live HTML playground and a menu-bar AI assistant with human-in-the-loop shell gates.

  • tauri
  • webcanvas
  • agents
  • ollama

Two apps, one pipeline

Both Gnomad Webcanvas and the Gnomad desktop assistant share a Tauri 2 + React 19 foundation, but they solve opposite problems:

AppJob
WebcanvasPrototype UI in HTML/CSS/JS with Monaco panes and live iframe preview — browser or desktop
GnomadMenu-bar AI with real shell and filesystem tools — not simulated chat

Webcanvas v0.1.0-beta.5

Full macOS, Windows, and Linux installers on GitHub. Highlights:

  • Resizable Monaco panes with CDN library toggles (Tailwind, GSAP, Three.js, etc.)
  • Viewport presets, designer tools, ZIP export
  • LZ-compressed share URLs — no backend
  • Browser demo for zero-install trials

Product page: /apps/webcanvas

Gnomad v0.2.0-beta.1

The assistant connects DeepSeek, OpenAI-compatible APIs, Ollama, or local GGUF — then runs a multi-step agent loop with human-in-the-loop gates:

  • Sudo Gate — cryptographic approval before privileged commands
  • Path Gate — tokens for filesystem writes
  • Live terminal — xterm.js stream on every command card

Release filenames use 0.2.0-1 (not the git tag suffix) — a gotcha when wiring download pages; the site config must match the actual asset names from gh release view.

All three platforms shipped in this wave: .dmg, .exe, .msi, .AppImage, .deb, .rpm.

Release hygiene

  1. Tag on GitHub → CI or manual upload of artifacts
  2. Mirror to .downloads-staging/ before Hostinger deploy
  3. Update apps.ts filenames and available flags per platform
  4. Add or refresh the matching /projects/ case study for portfolio cross-linking

Takeaway

Tauri makes cross-platform desktop feel achievable for a solo studio — but download URL discipline is the hidden work. Treat release asset names like API contracts and test them with a real mirror script, not hard-coded guesses.
