One prompt. Five agents.
Zero conflicts.

Jupiter splits your coding task across parallel AI workers that share context, coordinate in real-time, and never step on each other.

What changes with Jupiter

Today

With Jupiter

One agent, one task at a time

Up to 5 parallel workers

Agents start blind on your codebase

Planner pre-analyzes symbols, deps, modules

Parallel agents create file conflicts

Exclusive file ownership, zero conflicts

No coordination between agents

Shared memory bus, real-time sync

"It compiles" = done

Validator catches stubs, dead code, async bugs

How it works

You describe the task

"Refactor the auth module, add tests, update the docs"

Jupiter plans and deploys

The Planner analyzes your codebase, assigns each worker exclusive file ownership, and launches them in parallel.

Workers coordinate and deliver

Workers share state through a memory bus. When one finishes, others adapt. No merge conflicts. No wasted work.

“Other tools multiply speed.
Jupiter multiplies intelligence.”

A single agent lands blind on your codebase. A Jupiter worker arrives with full context, shared memory, and a team.

What's inside

Planner

Analyzes your codebase, creates typed briefings, assigns symbol ownership.

Workers

Parallel Claude CLI agents with shared context and MCP tools.

Memory Bus

Real-time state sharing between workers. No conflicts.

Validator

Static analysis catches what the compiler misses.

Why Parallel AI Agents Need Shared Context

Most AI orchestrators launch agents in isolation. Here's why shared context changes everything — and how Jupiter solves it.
