Hew v0.6.0

Hew v0.6.0 - Public API and MCP

Hew now has an API and MCP included in a new hew-cli command line client. The hew-cli can build and edit Hew models from a script, a shell, via an AI agent and - with the default "headless" mode - all with no UI required. If you do want to watch as it builds a model, there is also --live mode which will write to your already open Hew desktop instance.

This is cross-platform as always. Avoid the Linux AppImage if you want to use the API or MCP, though, as it's a bit of a pain to "extract" the hew-cli - use the .dep/.rpm packages to get both the desktop and the CLI easily.

Getting started with hew-cli and MCP: docs/API_GUIDE.md. Full protocol: docs/HEW_API.md

Downloads

The download page picks the right build
for your system, or grab a file directly:

Platform	x64 / Intel	ARM64 / Apple Silicon
macOS — disk image	universal .dmg	universal .dmg
Windows — installer	.exe	.exe
Linux — AppImage	.AppImage	.AppImage
Linux — Debian/Ubuntu	.deb	.deb
Linux — Fedora/openSUSE	.rpm	.rpm
Web — self-hosting tarball	.tar.gz	.tar.gz

• The macOS disk image is signed and notarized; one universal app
  covers Apple Silicon and Intel.
• Windows installers are not code-signed yet, so SmartScreen may
  warn on first run — choose More info, then Run anyway.
• On Linux, mark the AppImage executable (chmod +x) before
  first run, or install the .deb/.rpm.
• Desktop builds update themselves; latest.json and the
  .sig assets serve that built-in updater and are not meant
  for manual download.
• Or skip installing entirely: Hew runs in the browser at
  app.hew3d.com.
