Fractal Code
Hand it a plan and a team of coding agents builds the whole thing. One coordinator hands out the work, keeps the agents out of each other's way and checks every change before it lands. It keeps going for days on its own.
You'll join the Echofold newsletter, where Fractal invite codes will go out.
Run a fleet of coding agents
Inside Fractal Code
Six agents, one control room.
A scripted replay of a normal day: the coordinator hands out work, answers what it can and swaps a finished worker for a fresh one, and nobody has to watch.
What it takes off you.
Less to watch, less to remember, less to decide. Everything it does for you, most important first.
01It works while you're away.
- Takes a build all the way to production on its own, running unattended for days or even weeks.
- Reduces your cognitive effort: it keeps track of every agent, task and decision, and only asks you when a call needs making.
- Answers routine questions, approves safe steps and swaps a finished worker for a fresh one.
- Starts from a plan built in Fractal Workflows, or from the tickets you already have.
- Leave it working while you're on the beach or out hiking.
02Your AI, your budget.
- Claude Code, Codex and open-source models work side by side on the same job.
- Bring your own subscriptions and API keys, or pay as you go for open-source models.
- Spreads the work across your subscriptions, based on the limits left on each.
- Shows what AI has cost you on every project.
03Nothing lands behind your back.
- Every change is tested and scanned for security holes, risky libraries and leaked passwords before it lands.
- Only new problems hold a change up, so years of old warnings never stall new work.
- Changes merge one at a time, each checked against the latest version, with a record of every check.
04Safe by default.
- Your agents run in the cloud on your own encrypted, always-on server, so nothing stops when your laptop does.
- Each agent works in its own copy of the code, so they never trip over each other.
- Passwords and keys live in Fractal Secrets, away from the AI.
From a plan to production, on its own.
One real job, start to finish: online booking for a café's website.
You describe the goal, “let customers book a table online”, or start from a booking template. Fractal turns it into 14 tasks in the right order, and marks the 3 only you can do, like setting your opening hours.

Where it stands
Private beta, and what that means.
Worth knowing before you join the waitlist.
Private beta, by invite.
Fractal Code is open to private beta accounts. Join the waitlist and your invite code comes through the Echofold newsletter.
Your machine or the cloud.
It runs on your own Windows machine, or on an encrypted cloud server set up for you so it keeps going around the clock.
It drives your AI tools.
Fractal Code isn't a model. It runs the AI tools you already pay for, like Claude Code and Codex, or open-source models you pay for as you go.
