Operational infrastructure / for small teams
You wrote the programs.
Now put them to work.
Fat Controller turns scripts, services, watchers, and automations into real operational processes — running where they belong, visible and coordinated for your whole team.
Run anywhere. See everything. Keep it moving.

All nodes healthy.
Queued on Alpha-Mac.
Done. No issues.
A script is not an operation.
A useful program still depends on its author remembering to run it, watching it while it runs, knowing where it lives, interpreting its failures, and telling everyone else what happened.
Fat Controller changes that.
02
The program runs where the program belongs.
Maybe that's a Windows workstation with the network access nobody else has. Maybe it's a Mac mini quietly running overnight. Fat Controller coordinates the operation without forcing the workload to move somewhere unnatural.

The firepower of a technology department. Without the department.
Fat Controller gives small teams scheduling, shared jobs, machine visibility, secrets, and coordination — without forcing them to become a platform department.
05
An engineer who understands how Fat Controller works.
Describe an operation in plain terms and have the Engineer help turn your programs, schedules, and machines into something coherent.
The Engineer
Any issues with Daily Pricing this week?
All runs succeeded. One start was 2 minutes late Tuesday — nothing critical.
Today
A real, repository-grounded product assistant — explains how Fat Controller works, walks through configuration, troubleshoots what you're seeing.
Direction
Increasingly helping understand and operate jobs, machines, dependencies, and state — not just answering questions about them.
06
People. Programs. Agents.
People
Stay in control. Decide what runs, get told when it matters.
Programs
Do the repeatable work, reliably, without someone standing over them.
Agents
Participate alongside the team — another operator on the grid, not a separate system.
Underneath, Fat Controller coordinates through Vesper — Calapi's shared communications fabric. You'll never need to think about it to run your operation.
Serious machinery. A little personality.
Personality Packs
Once the operation is running, the control room can wear a different face. The portrait, the voice, the daily quote — the machinery underneath doesn't change.
Showing built-in catalog data.
Start with one program. Put it in motion.
You don't need to re-architect anything. Point Fat Controller at the one script you keep meaning to babysit, and stop babysitting it.
