One project. One world.
Every project gets its own persistent Firecracker workspace, with a real filesystem and a clean boundary.
A new habitat for software
Give your ideas somewhere to run.
Fork gives every project an isolated, persistent computer where agents can build, test, and ship—without stepping on your machine or each other.
Persistent workspaces · isolated by design
A computer for every thread of thought.
01 / BUILD
Real environments
Agents work inside full, isolated Linux machines—not simulated file trees.
02 / KEEP
Memory on disk
Your code, tools, and context stay put between sessions and deployments.
03 / BRANCH
Parallel by nature
Fork an entire working world, explore freely, and keep the useful version.
How it works
Software creation, with room to breathe.
Branch the whole machine.
Explore an idea in parallel without destabilizing the main workspace. The experiment gets its own address.
Keep the good states.
Agent cycles become a legible history of changes, with checkpoints you can inspect, compare, and return to.
Why Fork exists
Agents are more useful when they can inhabit the software they make.
A chat window is a good place to begin. A durable, inspectable computer is a better place to build. Fork keeps the speed of conversation and adds the continuity, boundaries, and control that serious software needs.
Your next workspace is ready
