MegaCoder

Parallel AI Coding Agents for Mac

MegaCoder is a native macOS desktop app that orchestrates multiple AI coding agents in parallel. Where most AI coding assistants work on one file at a time and lose context across complex changes, MegaCoder runs several agents at once, each working on a specific part of the task in isolated git worktrees, then merges results into a coherent whole. It decomposes a feature into subtasks, assigns them to specialized agents, manages dependencies between their outputs, and delivers a working implementation - all from a single window. Built for developers who want to use AI to ship multi-file, cross-cutting changes, not just autocomplete.

How it Works

01

Describe the Task

Tell MegaCoder what you want built in natural language. It analyzes your codebase and creates an execution plan.

02

Review the Plan

See how the task is decomposed into subtasks, which files each agent will touch, and how dependencies are managed.

03

Parallel Execution

Agents spin up in isolated git worktrees and work simultaneously. Monitor progress in real time from a single native desktop window.

04

Merge & Ship

Review the combined changes, approve the merge, and commit. What would take hours of manual work ships in minutes.

Features

Parallel Agent Orchestration

Decompose complex tasks and run multiple AI coding agents simultaneously, each in its own isolated git worktree. Merge results automatically when all agents complete.

Task Decomposition

Break down features, refactors, and migrations into independent subtasks that can be parallelized. The orchestrator manages dependencies between agent outputs.

Git Worktree Isolation

Each agent works in an isolated git worktree - no conflicts, no race conditions, no state corruption. Changes are merged cleanly when ready.

Multi-Language Support

Orchestrate changes across TypeScript, Rust, Python, Go, and any language your project uses. Agents understand your full codebase context.

Native Desktop Workflow

A native macOS app built for power-users. Describe what you want built, review the decomposition plan, watch agents execute in parallel, and approve the merged result - all in a single window.

Context-Aware Agents

Each agent receives relevant context about the codebase, related files, and the overall task. They make informed decisions, not isolated guesses.

Use Cases

Large Feature Implementation

Build complex features that span multiple files and modules by running specialized agents in parallel on each component.

Codebase-Wide Refactors

Rename interfaces, update API contracts, and migrate patterns across hundreds of files with coordinated parallel agent execution.

Multi-Service Changes

Implement changes that span frontend, backend, and infrastructure code simultaneously - each agent handles its domain.

Who it's For

Senior developers and engineering teams working on complex codebases who want to use AI agents in parallel for multi-file, cross-cutting engineering work.
