The tool you never
got round to building.

The tracker your team keeps rebuilding in a spreadsheet. The booking form the website is missing. Describe it in a sentence, try it in a preview, and put it live when you are happy.

Describe it, try it, publish it

It shows you a plan before it writes code and a working preview before anything goes live. Publishing is your button.

You

We track jobs in a spreadsheet and it's a mess. I want a page the office can update and each fitter can check on their phone. Overdue at the top. Photos when a job's done.

With developers or without

No developers? Kaer builds the tool, hosts it on a kaer.dev address and changes it when you ask. Have a team and a GitHub repository? It opens a pull request instead.

No engineers on staff

Hosted for you, changed when you ask.

You never need to see the code, though the files are there if you want them. Ask for changes in a sentence.

You have a development team

A pull request your engineers review.

It reads the codebase first and opens a pull request on GitHub. Nothing merges until someone presses Merge.

What people build first

Usually the spreadsheet everyone has outgrown.

  3. Totting up the week in a calculatorA report page that is always current
  4. The app a contractor built and leftFixed, documented and handed back

Common questions

Can Kaer turn a spreadsheet into an internal tool?
Yes. Attach the spreadsheet as .xlsx, .csv or .tsv, say who uses it and what they need to do, and Kaer builds a working tool you can try in a preview, without anyone writing code.
Does anything go live before I say so?
No. Kaer shows you a plan before it writes code and a working preview before anything goes live. Publishing is your button.
Where does the finished tool live?
Kaer can host it on a kaer.dev address. If you have developers, it can instead open a GitHub pull request for them to review.
