Agent-Up

Agent-Up is a local runtime control plane for parallel AI-assisted software development.

It manages the running development environment around applications: workspaces, Git worktrees, application processes, port allocation, Docker services, isolated browser profiles, logs, diagnostics, event history, and automation surfaces.

Agent-Up is not an IDE, application framework, deployment platform, Docker replacement, Git replacement, or production orchestrator.

Development Preview: Agent-Up is under active development. CI produces preliminary platform artifacts, and installer behavior is still being hardened. APIs, configuration, and workflows may change without notice.

Why Agent-Up Exists

Parallel coding agents make runtime review harder. Each agent may need to run the same application from a different branch, with its own ports, browser state, infrastructure, logs, and diagnostics. Traditional local development workflows usually assume one developer running one application instance.

Agent-Up is built to make those parallel workspaces reviewable without process, port, infrastructure, authentication, or browser-session collisions.

What Currently Works

See User docs for the product map and Current Limitations for status labels. Shipped surfaces include Server-owned workspaces, Desktop, Mobile, CLI, Git review, ACP agents, five MCP servers, and development-preview packages.

Current Limitations

Agent-Up is a development preview: packages exist, but they are not a stable update channel. REST, MCP, and agent-up.json contracts may change. Browser isolation, diagnostics, event recording, and validation-flow export are Preview or Experimental as labeled in the limitations page. There is no production support commitment.

Architecture

AgentUp.Server is the single source of truth. Desktop, CLI, MCP clients, and future integrations are clients of the Server: they may display state and request actions, but they must not own runtime state or duplicate orchestration logic.

Contributor architecture details live in the Developer Guide, especially Architecture, Workspaces, and Packaging.

Requirements

• .NET SDK 10.0 or a compatible SDK for the current target framework.
• Git.
• Docker and Docker Compose for repositories that declare Docker services.
• Node.js and npm for the documentation site.
• Nix on NixOS or Linux systems that need the provided native desktop dependency shell.

Agent-Up may work on additional platforms, but the current development setup has only been verified on NixOS.

Running From Source

Source lives at https://github.com/themassiveone/agent-up. Development-preview packages are published from https://github.com/agent-up-oss/agent-up/releases.

Restore and build:

dotnet restore agent-up.sln
dotnet build agent-up.sln

Start the server:

dotnet run --project AgentUp.Server

The repository launch profile currently uses http://localhost:5001. Packaged Server services listen on http://localhost:5000.

Start the desktop:

dotnet run --project AgentUp.Desktop

On NixOS, use:

./run-desktop.sh

Register a repository that contains an agent-up.json:

dotnet run --project /path/to/AgentUp.CLI -- start --server http://localhost:5001

Example agent-up.json

{
  "name": "My App",
  "applications": [
    {
      "name": "Frontend",
      "command": "npm run dev",
      "path": ".",
      "ports": [
        { "variable": "PORT", "defaultPort": 3000 }
      ]
    }
  ]
}

Design And Marketing

AgentUp.DesignSystem/ is the single source of truth for Agent-Up product UI, documentation, screenshots, and marketing presentation. Its canonical HTML/CSS catalog compiles to React Native objects and Avalonia resources and styles consumed by Mobile and Desktop. The public responsive showcase is linked from the documentation navbar at /design-system; implementation and external-repository usage are defined in the design-system developer guide.

Build the docs locally:

npm --prefix docs install
npm --prefix docs run build

Contributing

Contributions are welcome while the project is in preview, especially focused bug reports, setup fixes, docs corrections, and small implementation improvements.
