# How to Vibe Code Your Own Windsurf (and Stop Paying for It)

- Estimated effort: 6+ months of full-time work

## Verdict

Keep paying for Devin Desktop; forking a production text editor and building a multi-agent orchestration desktop environment is a massive multi-year undertaking.

Replicating Devin Desktop requires forking and maintaining an entire text editor (VS Code architecture), engineering a sub-millisecond incremental codebase indexing engine, and building a secure background agent execution loop that runs terminal commands and modifies files across git worktrees. An AI coding agent will fail on the deep systems-level integrations, native UI rendering layers, and complex process sandboxing required for a local IDE.

### What you can't replicate

- Enterprise security compliance and VPC deployment tooling
- Deeply optimized native text editor performance and tree-sitter integration
- The massive proprietary infrastructure required to host and serve fast context indexing for large codebases

## What it does

An agentic integrated development environment and command center built to manage fleets of local and cloud-based AI coding agents with real-time codebase indexing and multi-agent workflows.

### Core features

- Agent Command Center with Spaces and Kanban board
- Multi-agent local and cloud execution engine
- Real-time incremental codebase symbol and vector indexing
- Tab autocomplete prediction and inline edits
- Agent Client Protocol (ACP) and Model Context Protocol (MCP) server integration
- Git worktree isolation per space

## The business

### Pricing

- Free: $0 — Light quota for coding with agents
- Pro: $20/mo — Full model access and increased quotas
- Max: $200/mo — Significantly higher quotas for power users
- Teams: $80/mo + $40/mo per seat — Collaboration and centralized admin

Team size: 200.

## The hard parts

- Forking and maintaining a performant IDE base (VS Code architecture with native C++/Rust layers)
- Building a lightning-fast incremental vector and symbol indexer that returns context in milliseconds
- Orchestrating autonomous multi-step background agents that safely write files and execute shell commands across git worktrees
- Managing complex protocol interoperability for dozens of MCP servers without degrading model reasoning

## How to vibe code Windsurf

### Prerequisites

- Node.js (free): Required for building Electron desktop shell applications and TypeScript tooling
- GitHub (free): Repository hosting and version control for your desktop application project

### Recommended AI tools

- Claude Code: Provides advanced multi-file planning and code generation for building boilerplate components
- Cursor: Useful for iterative UI work and editing the Electron frontend codebase

### Stack

- Frontend: Electron + React + TypeScript
- Backend: Node.js + Rust background agent runner
- Database: Turso
- Auth: better-auth
- Other: Vercel AI SDK, Anthropic API

### Hosting

- Fly.io (Hosting companion cloud agent execution backends): $5/mo

### Build guide

1. **Electron Application Scaffolding** — Initialize a cross-platform Electron application shell using TypeScript, Vite, and React to serve as the desktop container.

```
Scaffold a new Electron application using Vite, React, and TypeScript. Set up a secure main process and renderer process structure with context isolation enabled. Configure basic window management, custom title bar styling, and a dark theme dashboard layout with sidebar navigation for Sessions, Spaces, and Settings.
```

2. **Agent Command Center Kanban UI** — Build the Kanban board and Space manager interface to track parallel agent tasks and workflows.

```
Build a Kanban board component in React using Tailwind CSS that mimics an agent command center. Include columns for 'Running', 'Waiting for review', and 'Done'. Each card should display agent status, git worktree name, elapsed time, and summary of changes. Implement drag-and-drop state management for tasks across spaces.
```

3. **Local Codebase Indexer** — Implement a background file scanner and indexing service to parse source files and build a local symbol search index.

```
Implement a Node.js background file indexing service using chokidar to watch local directories. Parse code files for symbols, functions, and classes using tree-sitter or regex parsers, and store metadata in a local SQLite database via Turso for fast retrieval.
```

4. **Agent Loop Orchestration** — Create the background execution loop that interacts with LLM APIs to read files, write diffs, and execute terminal commands.

```
Create a TypeScript agent orchestration loop using the Vercel AI SDK and Anthropic API. The agent must be able to read repository files, generate text diffs, and execute safe terminal commands in isolated git worktrees. Implement self-correction logic when build or test errors occur.
```

5. **MCP Protocol Integration Layer** — Add support for Model Context Protocol (MCP) servers to allow external tool execution within agent sessions.

```
Build an MCP client integration layer within the Electron app backend that spawns and communicates with local Model Context Protocol servers over stdio. Expose discovered tools dynamically to the active agent execution loop so agents can query external services like SQLite or filesystem tools.
```

### Cost vs paying

**Starting costs (one-time):**

- AI coding credits: $40
- Total: $40 one-time

**Ongoing costs (monthly):**

- Cloud backend VM hosting: $5/mo
- LLM API overages: $15/mo
- Total: $20/mo

- Paying for the SaaS instead: $20/mo
- Build time: 120 hours
- AI tool credits: $40
- Break-even: Never (paying is vastly more efficient)
