Buy it once. Run it on your own machine.
Build Without Limits
Two desktop tools from Gattaca — one puts a whole team of AI coding agents to work, the other turns a plain-English description into a working tool that keeps your data. Works best with the agents you already pay for: Claude Code and Codex, plus hundreds of other models when you want them.
Runs on your machine · use Claude Code or Codex on the plan you already pay for, or bring your own API key · no account to create
Available now · the first tool
CodonTerminal
The cockpit that runs on top of the coding agents you already have. Point each pane at its own task and model, or hand the whole board a goal and let it work through the list on its own.
- Up to 10 agent sessions side by side — Claude Code and Codex together.
- A task board that runs itself, with a reviewer checking the work.
- A different task and model in every pane, switchable mid-conversation.
Works with Claude Code, which you install separately (it’s free) — and with OpenAI’s Codex CLI if you have it. CodonTerminal is the cockpit; they’re the engines it drives.
Yours to keep
Buy it once and the copy you download is yours. It keeps working even if we disappear — and it changes when you ask it to.
Runs on your machine
A native desktop app, not a web service. Your tools and their data stay on your own computer.
Your key or your subscription
Bring an OpenRouter key, an Anthropic key — or your existing Claude Pro/Max plan through Claude Code. Already run your own LiteLLM gateway? PromptDeck can point at that instead. No extra platform fee.
Nothing in the middle
No account to create, no telemetry by default, no Gattaca server in the loop. Only the prompt you run goes to the model you chose.
The gap
Powerful shouldn’t mean complicated.
The most capable AI tooling today comes wrapped in the most friction: cloud dashboards, per-seat subscriptions, config files, and a terminal juggling act — whether you code every day or never.
Gattaca packages that power as real desktop apps that just run — download, open, work. On your machine, on your terms. How far you take them is nobody's call but yours.
Available now · the second tool
PromptDeck
The tools you wish you had, without waiting on a developer. Six are already built in and open in one click: an invoice tracker, a client manager, a booking scheduler, an inventory tracker with reorder alerts, a lead tracker for your pipeline, and a builder that turns any description into a new one. Run the one you need, then change it just by describing the change — the rows you enter stay put between runs, totals are worked out on your own machine, and everything exports to Excel. Need something none of them covers? Describe it and keep it. Already have the data? Point it at a spreadsheet or your database and just ask — in plain English — and you get an answer worked out from your actual rows, with the numbers behind it shown underneath. And when you only need a quick one-off — summarize this, rewrite that — the same app runs prompts too, with eighteen ready-made ones included. It can also wear your business rather than ours: put in your logo, name and contact details once and they head every tool you keep, so the invoice or quote you print goes out on your own letterhead.
- Six ready-made tools open in one click: an invoice tracker, a client manager, a booking scheduler, an inventory tracker with reorder alerts, a lead tracker for your pipeline, and a builder for anything they don't cover. Useful in the first minute, and yours to keep.
- Your tools remember: rows you enter stay between runs, and you change a tool just by describing the change, with edits to saved data shown as a diff before anything is written.
- Everything you track rolls up into running totals worked out on your own machine, and exports to Excel or as a standalone file that opens in any browser.
Two tools, one question
Which one do I need?
They solve different problems. The quickest tell: are you writing software, or do you just want the tool that does the job?
Put a whole team of AI coding agents to work at once.
- Pick it if
- You build software and want to run several AI coding agents at once instead of babysitting one chat.
- What you make with it
- Real code, in your own repo — a grid of agents you point at tasks, plus a board that can run itself.
- Do you need to code?
- Yes. It drives coding agents across a real codebase — it's a developer's cockpit.
- What it needs to run
- Claude Code (free) on your machine, and a code project to work in. Add OpenAI's Codex and it shows up too.
- Runs on
- Windows and Linux, both on the current release. macOS isn't sold yet.
Describe a tool. Keep it. It remembers.
- Pick it if
- You don't code, but you keep wishing you had the right tool for the thing you do every week.
- What you make with it
- Working apps that keep their data. Six come built in — invoices, clients, bookings, stock, leads — and you can describe new ones. Or run quick one-off prompts.
- Do you need to code?
- No. You describe the tool in plain English and change it the same way.
- What it needs to run
- Your Claude Pro or Max subscription through Claude Code — no API key — or an OpenRouter key for other models.
- Runs on
- Windows. It's a portable app — download and run, no installer.
Plenty of people own both — CodonTerminal for building software, PromptDeck for running the business around it. Together they're $59 instead of $78. See what they cost →
The idea
Built for the ones who adapt.
Most software makes you work the way it was designed. These tools go the other way: you describe what you actually do, and they take that shape — then change again when the work does.
- Describe what changed and the tool changes — a new column, a new field, a different calculation.
- Your data comes with you. Rows you entered stay yours, and export to Excel or a standalone file whenever you want them elsewhere.
- Both tools are a one-time purchase today: $49 and $29, and the copy you download is yours to run.
- It keeps working without us — a real app on your machine, not a login to our servers.
- No account, no sign-up, no telemetry by default. It runs on your terms.
