Environment Compatibility

Composer Studio runs on the following operating systems, runtimes and browsers.

Requirements

Component	Version	Notes
Operating system	Ubuntu 22.04, 24.04	The launch scripts are Bash and open the browser with xdg-open.
Python	3.10, 3.12 or 3.14	flexivpdk needs 3.10 or newer, and the pinned flexivrdk has builds only for these three. Ubuntu 22.04 ships 3.10 and 24.04 ships 3.12.
Node.js and npm	20.19+ or 22.12+	Needed to build the editor. Older Node.js releases fail during npm run build.
Flexiv PDK (flexivpdk)	Same release as the server	Installed from PyPI (Install Composer Studio).
Flexiv RDK (flexivrdk)	1.9.4.1	Pinned in app/backend/requirements.txt; used to connect to real robots running Flexiv software package v3.11.3.
PDK server	unknown	Running on the same computer, localhost:50052 by default.
Web browser	Current Chrome, Edge or Firefox	WebGL and WebSocket support are required.

Version compatibility

Composer Studio has no version number of its own: it follows the PDK release of the flexivpdk package it runs with. Install the flexivpdk version that matches your PDK server. A mismatch usually shows up as gRPC errors from every request.

Same machine as the server

Install and run Composer Studio on the same computer as the Flexiv PDK server. The backend reads and writes mesh, URDF and area files directly in the PDK Release Folder, then passes the server the matching path, so a server on another computer is not supported. A server running in a container on the same computer works; see Launch Composer Studio.
