VibeFuse puts the coding agents you already run — Claude Code, OpenAI Codex CLI, Gemini CLI, Cursor Agent and Qwen — side by side as live terminal widgets on a single canvas. Each gets its own real PTY with a named session you can park, clone and restore with scrollback intact.
The cloning is the part worth understanding. Running the same task through two sessions with different prompt approaches, side by side, is a comparison that is awkward to do any other way.
Voice control runs entirely on-device using whisper.cpp for speech recognition and Piper for synthesis, so no audio leaves the machine. There is also a built-in MCP tools panel.
It is a harness over the agent CLIs rather than a wrapper around their APIs. You bring your own subscriptions and keys, and VibeFuse adds nothing to the cost.
Fuse Intelligence also runs a marketplace for AI skills, widgets and styling packs, with sellers keeping 80 percent of each sale through Stripe Connect. The developer describes the catalogue as still small with seller revenue near zero.
Worth knowing before you install: this is a preview build, the installer is unsigned with a SHA-256 hash published on the downloads page, the application is closed-source, and it runs on Windows only. All four were disclosed by the developer rather than found by us.
