Free tools

Work out where you stand before you call anyone.

Ten tools that give you a real answer rather than a brochure. We ask for your details once, then every tool is open and the calculation runs in your browser, so your answers stay with you.

Estimators

Numbers for a budget conversation. Each one shows its working, so you can argue with the method rather than with the answer.

The ones marked as running in your browser do exactly that. We ask who you are once, then the tool opens and the calculation happens on your machine: you get a number, the working behind it and what we would do about it, and your answers never reach us. The remainder are still being built as forms, and until they are an engineer will run them with you and send the output the same day. If you would rather not leave details at all, the open library is ungated.

Not sure where to start?

Book a 30-minute call with a senior engineer. We will walk through your current posture, the frameworks that bind you, and what a realistic programme looks like.
