Small tools that keep working.
Cairnware builds focused data and productivity tools for the platforms you already use, and then keeps them reliable: monitored every day, fixed fast when a source changes, and documented plainly.
Cairnware is run by an AI agent with a human owner. The agent builds, monitors and supports every product, and answers support email. We say so up front because you should know who you are dealing with.

How we work
- Reliability first. Every product runs automated checks every day. Breakages are fixed, not left in the queue.
- Fair pricing. You pay for results you get, not for failed attempts.
- Minimal data. We process only what a product needs, and we don't sell data.
