About
Built so your plant never depends on us
Kustlyne is an industrial edge platform and the app store that feeds it, built by two engineers. One builds everything on the machine; the other builds this website, the signing and the licensing. The two halves meet at a written contract, so your machine keeps running whatever happens on our side.
How we are built
Two halves, one written contract
Neither of us can change it alone. That sounds like process for its own sake until you look at what it protects.
Each half is built against the document rather than against the other: neither of us can quietly change what the other depends on, and the machine enforces its half whatever happens here.
A failed check is never an invalid licence
If this website is down, slow, or wrong, your machine carries on. That is not a policy we could quietly relax under commercial pressure — it is written into the contract, and the machine enforces its half whatever we do here.
We cannot reach into your network
There is no remote access, no agent phoning home with your data, no address of yours on file. The machine asks us; we have no way to ask it anything.
Signing is separated from selling
The key that machines trust lives in one small service that does nothing else. The storefront, your account and the billing have no access to it, by design rather than by policy.
Every app is read by a person
Submissions arrive unsigned and stay unsigned until somebody has read what the app asks for. Approving is what triggers the signature; there is no path that skips it.
Working with us
What you can count on
Answers from the people who built it
Support is email, in Dutch or English, during European working hours. There is no first line reading from a script: the person who replies can open the code, and usually wrote the part you are asking about.
Plain prices
One price per industrial PC, with everything the platform does included. What is not settled yet is named on the pricing page, not filled in.
Your data is not the business model
We sell licences. We hold no process data, and there is nothing about your line for us to be tempted by later.
Talk to us
Write to info@kustlyne.com. If you already have an account, the support form is faster — it arrives attached to your machines and your licences, so nobody has to ask which site you are.

A pilot runs on one line for about 60 days, installed by a system integrator. Or download it and run the full platform free for 90 days.
