DecisionManager Desktop IDE

A purpose-built desktop workbench for decisions — repository, author, validate, deploy — built on Tauri 2, not a rebranded editor. Positioned as a modern alternative to IBM ODM Eclipse Rule Designer, while the VS Code extension and VSCodium Studio remain available for power users.

DecisionManager Desktop IDE

v0.1.0scaffold

From-scratch Tauri 2 decision workbench (not VS Code). Source: repo ide/. Developer path: npm run tauri:dev. Signed installers appear under binaries[] only when packaging publishes them — never invent production binaries.

Live
  • Tauri 2 shell for macOS, Windows, and Linux
  • Connect + JWT against Platform API
  • Workspace switcher + project repository list (Manager API)
Partial
  • Visual table/flow/BAL editors in desktop (reuse Manager editors — next milestones)
  • Validate / dry-run / deploy from the desktop strip
Residual
  • Offline local BAL / Rete engine
  • Eclipse Rule Designer project / Java XOM JAR
  • Full 264-command parity with the VS Code extension

Get started (developer scaffold)

From a DecisionManager checkout with the API stack running (./scripts/stack.sh start).

Desktop shell (Tauri)

cd ide && npm install && npm run tauri:dev

UI only (browser)

cd ide && npm install && npm run dev

Native installers are not listed yet (unsigned engineering path only). When packaging publishes artifacts they appear here — we never invent download links.

How it relates to Studio & VS Code

All three talk to the same Manager / Platform / Runtime APIs. One authoring model — no second rule store.

Prefer VS Code today?

Install Decision Manager Studio (VSCodium + extension) or the .vsix for the full measured command surface while Desktop IDE editors land.

What this install does and does not do

  • No full branded Studio binary is published for this OS yet. The installer installs VSCodium or VS Code (if needed) and the Decision Manager extension v0.4.5 (264 commands) — the same full IDE surface, not a reduced build.
  • Desktop Studio and VSCodium use Open VSX for optional extensions — not the Visual Studio Marketplace. Some Microsoft-only extensions will not install.
  • Unsigned desktop builds may be blocked by Gatekeeper or SmartScreen until notarized or Authenticode-signed. Prefer checksums on the download page.
  • This is the developer desktop IDE, not a replacement for the browser Decision Manager console. Authoring, ops, and admin UIs stay in the web consoles for non-desktop workflows.
  • INSTALL_MODE=manager opens the Decision Manager profile (workspace defaults and activity-bar focus). Change mode by re-running with INSTALL_MODE=manager|server|admin.
  • Rule Designer analogue, not Eclipse: residual honesty — no Eclipse project on disk, no Java XOM JAR/B2X, no Ant ruleapp headless, no offline local BAL parser. Palette size is the measured 264 commands on extension v0.4.5; residual capabilities stay residual (see Help → Rule Designer matrix).
