Why developers search for a free AI agent harness

Open-source & free agent CLIs, one canvas

Bring the coding agents you already use. VibeFuse is the free desktop layer that keeps them arranged with terminals and browsers — ideal if you want high capability without paying for yet another IDE seat.

Marketplace widgets that sync

Browse fuseintelligence.org/marketplace, save to your library, and widgets sync into the canvas on launch. Publish from Settings → Marketplace with manifest.json + index.html.

Built for multi-agent workflows

Compare approaches across Claude and Codex in parallel, keep a terminal watching tests, and leave a browser on docs — that is modern AI coding agent desktop work.

Free forever, same Fuse account

One Fuse Intelligence login covers free VibeFuse and paid VocalFuse when you need system-wide dictation outside the canvas.

Widget canvas — every surface the harness needs

Terminal + Files

PowerShell with session restore beside a Files explorer that previews images, video, audio, and PDFs from your workspace folder.

Browser, YouTube, saved pages

Embedded Chromium for docs and research; bookmark pages as chromeless widgets. Marketplace iframe widgets load via widget://.

Vibe Agent + coding CLIs

A tool-using chat assistant plus Claude Code, Codex, Gemini, Cursor, and Qwen — run multi-agent side-by-side on one canvas.

Voice, sessions, and control

Desktop architecture — built for Windows

Main process owns PTYs, voice engines, and MCP in C:\vibefuse\; the React renderer is your widget canvas with twelve-tab Settings. Details in VibeFuse docs → Architecture.

VibeFuse FAQ

Is VibeFuse free?

Yes. Every Fuse Intelligence account gets a complimentary VF- license at no charge. There is no checkout and no monthly fee for VibeFuse. Create a free account, copy your key from Account → Product Keys, and install from /downloads/VibeFuse/.

What harness tools does VibeFuse include?

VibeFuse is a high-capability Windows AI agent harness: Terminal (PowerShell), Browser, YouTube, Files explorer, a Vibe Agent chat assistant that can create and edit Agent Skills, AI coding agent widgets for Claude Code, Codex CLI, Gemini CLI, Cursor CLI, and Qwen, Google Workspace and Drive MCP connections, and a live marketplace for community widgets and SKILL.md packages.

Does VibeFuse include free voice transcription?

Yes. Hold the title-bar voice dock to record. Speech is transcribed locally on your PC with whisper.cpp for free — useful for dictating prompts into AI coding agents without cloud audio uploads.

Does VibeFuse support a wake word?

Yes. Enable the Jarvis wake word in Settings → Voice and say “Jarvis”. VibeFuse plays a short “Yes, sir?” acknowledgement, then records your command. Local Whisper and Piper keep the whole loop on your PC.

How does Note-Taking mode work?

Switch the voice dock to Note-Taking, click the orb to record, and click again to stop. VibeFuse transcribes the take locally, summarizes it into bullet points with a title, and uploads it to your profile — review notes at Account → Notes or in Settings → Notes.

Can the assistant control the canvas layout?

Yes. Jarvis (voice) and the Vibe Agent chat widget can spawn, tile, resize, rename, focus, and remove widgets on command — for example “Jarvis, open three terminals and tile them.” Layouts use tile/fill/row/column arrange modes or exact x/y/w/h coordinates.

Does VibeFuse include free text-to-speech (TTS)?

Yes. Replies are spoken by Piper with the Jarvis voice, running on-device. With an OpenAI-compatible chat provider configured, the voice assistant speaks a short reply line — free local TTS for developer workflows, not a cloud TTS subscription.

Is VibeFuse open source?

VibeFuse is a free Fuse Intelligence product that wraps and runs popular open-source and vendor AI coding CLIs (Claude Code, Codex, Gemini, Cursor, Qwen) in one desktop canvas. Agent CLIs remain theirs; VibeFuse is the free harness, marketplace, voice, and session layer.

How do I install VibeFuse?

Register for free, copy your VF- key from Account → Product Keys, download VibeFuseInstaller.exe from /downloads/VibeFuse/, paste the key in Setup, and launch. The installer fetches the app and missing local voice models before first run.

Where is the widget marketplace?

Browse fuseintelligence.org/marketplace — save widgets and Agent Skills to your library while signed in. Widgets sync into C:\vibefuse\widgets and skills into C:\vibefuse\skills on next launch.

How do I publish a widget to the marketplace?

Build a folder with manifest.json and index.html, open Settings → Marketplace in the desktop app, and publish the folder. Your listings appear publicly on fuseintelligence.org/marketplace, and you can unpublish or republish any time.

What are Agent Skills in VibeFuse?

Agent Skills are Claude/Codex-compatible SKILL.md folders in C:\vibefuse\skills. They appear in the left-rail Skills section. Save them from the marketplace, drop a folder on disk, or ask Vibe Agent to create_skill / update_skill. Any connected provider agent can read the same files.

Can Vibe Agent create and edit skills?

Yes. Vibe Agent (and Jarvis) can list_skills, create_skill, update_skill, delete_skill, execute_skill, read_skill, and read_skill_file. The Skills rail and Settings → Skills refresh as soon as a skill is written.

How do I connect Google Workspace or Google Drive MCP?

Open Settings → Tools. Use the Google Workspace card (Gmail, Drive, Calendar, Docs, Sheets, Tasks, Slides, Meet, Contacts) or the Google Drive card (read-only Drive). Sign in with Google once — both cards share the same OAuth account — then Connect. Enable Workspace APIs in Google Cloud if tool calls fail.

Which AI providers does VibeFuse support?

Settings → Agent includes OpenAI, Ollama (Local), Ollama Cloud, NVIDIA NIM, Featherless, Google Gemini, Groq, Together AI, OpenRouter, Plugsky, and Custom OpenAI-compatible endpoints. Each card keeps its own API key, endpoint, and model.

What is Settings → Local Servers?

The fourteenth Settings tab: Piper endpoint/voice/speed/volume, Whisper endpoint and ggml model picker, HyperFrames Studio start/stop, Skill Seekers Connect, and Crawl4AI + SearXNG endpoints.

Can I sell skills I create in VibeFuse?

Yes. Finish Stripe Connect, set a price on Account → Marketplace, and publish. Sellers keep 80%. Buyers get the package in C:\vibefuse\skills or \widgets.

What is HyperFrames in VibeFuse?

A local HTML-to-video studio on port 4567. Vibe Agent can compose a video about your workspace folder, render an MP4 to C:\vibefuse\hyperframes\renders, and spawn a Video widget.

What is Skill Seekers?

A local Python MCP cloned to C:\vibefuse\Skill_Seekers. It searches docs-to-skill presets (React, Godot, Blender, Claude Code, Unity, and more) before you create a duplicate skill. No API key.
