MegaCoder
Parallel AI Coding Agents for Mac
MegaCoder is a native macOS desktop app for running AI coding agents at the scale a real codebase needs. Instead of one chat window, it runs many CLI sessions at once - each in its own isolated git worktree, so they never collide - and gives them a home: a board to plan the work, teams whose sessions coordinate through a shared mailbox, loops that keep re-prompting a session until it meets a stop condition, and a scheduler for the runs you want to happen without you. Around that sits the plumbing that otherwise rots by hand - the instructions, skills, slash commands and MCP servers a project needs, kept in sync across projects and mirrored into the formats other CLIs read. A companion iPhone and iPad app pairs with the Mac, so you can watch live sessions, read the terminal, and start new work away from the desk.
Highlights
How it Works
Add Your Projects
Point MegaCoder at the repositories you work in, and set up the instructions, skills and MCP servers each one should run with.
Start Sessions
Spawn a session per piece of work - on its own git worktree when it will touch files - or a whole team that coordinates through a mailbox.
Watch Them Run
Every session has a live terminal in one window, with loops, schedules and notifications for the runs you do not want to sit and watch.
Review and Land
Read what each session did, keep the work you want, and land it from the worktree it was written in.
Features
Many Sessions, One Window
Run several AI coding sessions at once across all your projects, each with its own live terminal, and watch them work from a single native macOS window.
Git Worktree Isolation
Every session can run in its own git worktree, so two agents working at the same time cannot collide, corrupt each other's state, or fight over a branch.
Agent Teams
Spawn a team of teammate sessions that coordinate through a shared mailbox, so a job too big for one session is split across several that can talk to each other.
Loops and Schedules
Keep re-prompting a session until it meets a stop condition, or put a run on a schedule so the work that should happen every morning happens without you.
A Board for the Work
Plan what the agents should do on a built-in board, with checkpoints you can return to and a record of what each session actually did.
Context That Stays in Sync
The instructions, skills, slash commands and MCP servers a project needs are managed in one place, kept in step across projects, and mirrored into the formats other CLIs expect.
Companion iPhone & iPad App
Pair your phone or tablet with the Mac to browse projects, watch live sessions, read the session terminal, and kick off new work while you are away from the desk.
Use Cases
Several Things at Once
Keep a feature, a bug fix and a refactor in flight together, each on its own branch, without any of them treading on the others.
Work Across Repositories
Drive sessions in several projects from one window, each with the instructions, skills and MCP servers that project expects.
Runs You Do Not Sit Through
Put a long job on a loop or a schedule and get a notification when it stops, instead of babysitting a terminal.
Who it's For
Senior developers and engineering teams who run AI coding agents daily and have outgrown a single chat window - several jobs in flight, several repositories, each needing its own branch and its own context.
FAQ
A normal assistant gives you one chat window. MegaCoder runs many CLI sessions at once across all your projects, each with its own live terminal and its own git worktree, plus the teams, loops, schedules and shared context that running agents at that scale actually needs.
Every session can run in its own git worktree, so two agents working at the same time cannot collide, corrupt each other's state, or fight over a branch. You review each session's work and land it from the worktree it was written in.
It is a native macOS desktop app. Every session runs in it - its own terminal, its own git worktree - and you watch them all from a single window. A companion iPhone and iPad app pairs with the Mac so you can follow sessions away from the desk.
Yes. A loop keeps re-prompting a session until it meets a stop condition, a scheduler starts runs on their own, and notifications tell you when something needs you.
Work that does not fit in one session - several features or fixes in flight at once, across several repositories, where each needs its own branch, its own context, and somewhere to be tracked.
