Installation

LoomFlow runs two ways: as a native Windows desktop app, or as a browser-based tool with nothing to install. Both are the same tool working on the same .loomflow project files — the desktop app adds native file dialogs, real file paths, and full offline use.

Install the Windows desktop app

The desktop app ships as a single installer named:

LoomFlow_<version>_x64-setup.exe

For the current release that is LoomFlow_0.3.0_x64-setup.exe. The installer is self-contained — run it and the app installs; there is nothing else to download or configure, and no other software is required on the machine. Because it’s a single file, a teammate who already has it can simply hand you the -setup.exe.

Once installed, launch LoomFlow like any other application. File open and save use native Windows dialogs, so any file on disk works — no browser restrictions apply — and the app works fully offline.

Use the browser version

The browser version needs no installation: open LoomFlow in your browser and start designing. It reads and writes the same .loomflow project files as the desktop app, directly on your own disk.

Caution

Use a Chromium-based browser (Chrome or Edge). LoomFlow opens and saves files through the browser’s File System Access API, which only Chromium-based browsers provide. With it, Ctrl+S silently re-saves to the same file you opened — just like a desktop app. In browsers without the API, the tool falls back to a plain file download on save and a file-upload picker on open — workable, but every save lands in your downloads folder and you’ll re-pick the file each session. For everyday use in a browser, stick with Chrome or Edge; for the smoothest file handling overall, use the desktop app.

Desktop or browser?

	Desktop app	Browser version
Install	One self-contained installer	Nothing to install
Works offline	Yes, fully	Needs a connection to load the tool
Open / save	Native Windows dialogs; Ctrl+S saves in place	Saves in place in Chrome/Edge; download fallback elsewhere
KiCad import (Pro)	☰ → Import → KiCad project / schematic… — point at a whole project or individual schematics	☰ → Import → KiCad schematic(s)… — pick individual .kicad_sch files

Both produce the same .loomflow files, so you can move between them freely — design at your desk in the desktop app, then open the same file from any machine with a browser.

Verify it works

Whichever route you took, launch LoomFlow. You should see an empty untitled document: a blank canvas, the ☰ file menu floating in the top-left corner (it shows the current file name — untitled for now), and a sidebar on the right with the Inspector, Library, and Issues panels. Open the ☰ menu and confirm New, Open…, Save, Import, and Export are all there — if so, everything is working.

From there, head to the quick start to build your first harness, or take the interface tour to learn the views and panels. Each project saves to a single portable .loomflow file that works offline and syncs when you want it — see collaboration.
