terms

what you agree to, and what we owe you.

tl;dr

checking the g-code before you cut is your job, every time. that does not change when kerf leaves alpha.

  • we are not liable for a broken bit, a ruined piece or a damaged machine
  • your drawings and projects stay yours
  • it is free, and comes with no warranty

the machine is yours

kerf writes g-code. your router turns that into a cutter at speed and a gantry in motion. before you run a file, play the preview, check the depths and the feeds against your machine and your stock, and stay within reach of the stop.

we cannot see your setup, your bit, or the piece on the bed. software cannot know that a number is wrong for a machine it has never met, so the last check is yours, and so is what the cut does.

this is not a condition of the alpha that expires when the software settles. it is how a cam tool and a machine divide the work: it writes the file, you decide it is safe to run, and a broken bit, a ruined piece or a damaged machine is not something we answer for, in this version or any later one.

your work is yours

your drawings, your projects and the g-code kerf makes from them belong to you. we claim nothing over them, and we do not use them for anything.

what it costs

nothing today. paid plans may come later. kerf is built for hobbyists and makers, and that is the measure any plan has to pass.

no warranty

kerf is provided as it is, with no warranty of any kind, and we are not liable for damage to your stock, your bit, your machine, or anything that follows from using it. where the law does not allow that to be excluded, the limit is whatever you have paid us, which is nothing.

on top of that, and separately, it is alpha right now: it will break in ways that are our fault, and saying so is not a formality.

your account

one account per person. do not use kerf to break the law, and do not attack the service or anyone else's projects. an account doing that gets closed.

changes

these terms change as the product does, and the date below is when they last did. using kerf after a change means the new version is the one that applies.

last changed 27 july 2026. questions go to the feedback page, and privacy is the other half of this.
