About PastiBeres
PastiBeres is a set of everyday tools built so small jobs get finished without extra apps, without accounts, and without uploading files.

Why it exists
Many online tools ask you to upload documents to servers you know nothing about. For internal files, contracts, or customer photos, that is an unnecessary risk.
We build tools that lean on modern browser capabilities — Canvas, Web APIs, WebAssembly — so processing happens on your own device.
Who is behind it
PastiBeres is built and maintained by PT Semesta Multitekno Indonesia, an internet service provider and network solutions company based in Banyuwangi, East Java.
That network operations experience is why the subnet planner — and the other browser-side tools here — exist.
Where it is going
Our focus is not tool count, but tools people actually use: fast, honest about limits, and storing nothing they do not need to.
Telling us which tool you need genuinely shapes what gets built next.
