Workspace where software builds itself.
Marshell exists because the tools of the last era — one human, one editor, one cursor — can't carry the next one.
Vision
Software that builds software — direct a workforce of agents instead of keystrokes you type.
Mission
Turn developers into orchestrators of parallel agents — planning, coding, testing, and shipping.
Open Source
Built in the open with inspectable agents, local execution, and code you can read and fork.
What we hold true
AI-first, human-final
Agents do the work; people make the calls. Every diff is reviewable, every action lands in a terminal you can open, and the merge button stays yours.
Autonomy needs visibility
Autonomous systems earn trust by being observable. Live traces, real shells, and a board that never lies are not features — they're the contract.
Local by default
Your code is your code. Execution happens on your machine, in your worktrees, with your keys. Nothing leaves unless you push it.
Parallel is the point
One agent is a novelty. Six agents, coordinating over a shared task graph across a grid of terminals — that's a new way to build.
From sketch to swarm
April 2026
The idea
Terminals, editors, and task boards were built for a world without agents. We start sketching a workspace designed around them.
May 2026
First swarm
Three agents resolve a dependency graph across tiled terminals for the first time. The canvas overlay is born to watch them think.
June 2026
Theme engine & task board
The drag-to-dispatch kanban ships alongside 40+ OKLCh themes and the dependency resolution engine deep dive.
July 2026
v0.1.0 public release
The 16-pane multiplexer, agent dispatch, and execution traces go public. One developer, an entire engineering team.
