What a one-person company does, and does not do
Descarty is run by its founder, who builds and sells the product alone.
What we do
We publish the price. You can try the product free for 14 days. You pay monthly and can cancel in any month. The developer replies to you by email within two business days.
What we don't do
No visits, no on-site work, no building it for you. The one exception is the one-month onboarding, online, where we build your first job together.
If Descarty went away
The engine, Dagu, is open source under GPL-3.0. The instructions you wrote in words stay on your computer as YAML files. When the Kitewell license expires, you can no longer run workflows in Kitewell.
What we build
Kitewell The runtime for AI agents
Software that replays the steps AI learned by doing a job once. When a screen changes, AI relearns only the steps that no longer match. It runs on your own PCs and servers.

About Dagu
Dagu, open source
Kitewell runs on Dagu, the open-source workflow engine Descarty develops. Anyone can read the source code to see how the engine works.
- License
- GPL-3.0
- Public since
- 2022
You can check what is inside
The engine's source code is public on GitHub. Before adopting it, anyone can check how it works and where it keeps data.
Your instructions stay with you
The instructions you write in words stay on your computer as YAML files, in a form people can read.
Dagu is a workflow engine that runs workflows defined in YAML. It is a single executable and needs no database. It combines scripts, commands, containers, SSH operations on servers, and more, and runs them on schedule.
Automation that the people who know the work can keep.

If a security incident occurs, we promptly investigate its cause, minimize the damage, and work to prevent it from recurring.
