An agent is a folder.

The system prompt, skills, MCP servers and settings are plain files in ~/AgentForge. Open them in Finder, edit them in your editor, commit them to git and send them to a teammate.

  • SYSTEM.md is the prompt
  • agent.json holds the model

Install skills in one press.

Search skills.sh from inside the agent and install a skill with one press. Skills use the open Agent Skills format. Switch one off without deleting it, and update it when its source changes.

  • Your own skills are never overwritten

Plug in any MCP server.

Browse the official MCP Registry. Hosted servers connect with a browser sign-in; local ones run through npx, uvx or Docker. Tokens stay on your computer, outside the folder you share.

  • Updates offered when a new version ships

Every agent has a face.

Name an agent and describe its job. Agent Forge draws it a character in a costume that fits the role. The face turns to follow your cursor and reacts when you click it, so you can tell your reviewer from your planner at a glance.

  • Costume suggested from the role
  • Redraw it whenever you like

Talk to it. ⌘J from anywhere.

The composer opens into the conversation: streaming replies, reasoning and every tool call as it happens. Steer while it works, stop it, or start a fresh conversation.

  • Pick a project folder and it works there

Chain agents on a canvas.

Drop agents onto a workflow and pass each step's output to the next with {{input}}. Ask a step for structured JSON, then branch on it with If/Else conditions written in CEL.

  • Start, Agent, If/Else, Wait, Note, End

Press Run. Watch every step.

Type a message and run the workflow. The log shows who is working, what each step received and what it returned, so you can check the result instead of taking it on trust.

  • Runs inside the project you pick

They look like you.

On first launch, three photos of you become the base character. After that, every agent you create wears a costume that suits its job. Move your pointer and they follow it. Click one to say hello.

  1. Three photos of youSent once from your computer to the image model you pick, then deleted. Agent Forge has no servers of its own.
  2. Your base characterNine head angles and nine reactions, drawn once.
  3. A costume per agentSuggested from the agent's name and job.

These are real Agent Forge characters, drawn from the maker's photos. Yours will look like you.

Built on files and open standards.

Nothing important is hidden in a database. If you can read a folder, you can read your agents.

Your files
Agents, workflows and projects are folders and JSON on disk. Version them, diff them, back them up.
Any model
One Vercel AI Gateway token reaches Claude, GPT, Gemini and more. Set a default, override it per agent.
Open formats
Agent Skills, the Model Context Protocol, skills.sh and the MCP Registry. Nothing proprietary to learn.
Checkable output
Steps can hand over typed JSON, and conditions are expressions you can read.
Keyboard first
⌘K jumps to any agent or workflow. ⌘J talks to the agent in front of you.
A native app
A small Mac and Windows app built with Tauri, in light, dark or system appearance.

Questions, answered plainly.

The fastest answer is to make one agent. It takes a minute, and its face arrives a couple of minutes later.

Download for macOS Download for Windows
Is Agent Forge free?

Yes. The app is free to download. Model calls are billed by your AI provider through the Vercel AI Gateway token you add in Settings.

What is an agent in Agent Forge?

An agent is a folder in ~/AgentForge/agents. It holds agent.json (name, model, settings), SYSTEM.md (the system prompt), a skills folder and an mcp folder. You can open, edit, version and share it like any other folder.

Which AI models can my agents use?

Any chat model available on the Vercel AI Gateway, such as Claude, GPT or Gemini. Set a default in Settings and override it per agent.

Where do my agents and conversations live?

On your computer, as files under ~/AgentForge. Model requests go to the model you picked through the Vercel AI Gateway. MCP sign-in tokens are stored on your computer, outside the shareable agent folder.

Do I need to write code?

No. You create agents, install skills, add MCP servers and wire workflows in the app. Everything it saves is plain text, so you can also edit it by hand.

Can I use my existing skills and MCP servers?

Yes. Skills use the open Agent Skills format (a folder with a SKILL.md), and MCP servers are standard stdio or hosted servers. Install from skills.sh and the MCP Registry, or drop your own files into the agent folder.

What happens to the photos for my avatar?

They go once from your computer to the image model you chose, through your own gateway key, and are deleted as soon as the character is drawn. Agent Forge has no servers of its own, so nothing is uploaded anywhere else.

Does it run on Windows or Linux?

Agent Forge runs on macOS and Windows. Linux is not supported yet.

Assemble your first team.

Download Agent Forge, pick a folder to work in and create your first agent. It gets its face within a couple of minutes.
