ThiersLabs

Open-source software lab - the Netherlands

This is ThiersLabs.A lab for fast desktop tools. cross-platform apps. compression codecs. custom typefaces. things built from scratch. open-source software.

ThiersLabs is a small, independent open-source lab by Sam Thiers. Every project is built from scratch, free to download and explained in the open - most of them with a live demo you can try right in your browser.

Featured projects

All projects

SAT-ZIP

Fast desktop archiver with its own codec

A Windows archiver powered by a custom high-throughput LZ codec whose decompression beats LZ4. Reads and writes .satz, .zip, .7z, .tar and .tar.xz, integrates into the Explorer right-click menu and ships with a built-in benchmark lab.

  • C++
  • AVX2
  • Dear ImGui
  • CMake
  • Inno Setup

SAT-OBELISK

A small sponge-based cryptosystem

Built on one 384-bit permutation: authenticated encryption, hashing, key derivation, key wrapping and file encryption. A research and teaching project, not a replacement for audited crypto.

  • Python
  • Cryptography

How the lab works

  1. 01

    Open source

    Public projects live on GitHub under open licenses. Read the code, learn from it, build on it.

  2. 02

    Try it first

    Live demos run in your browser: compress a file with SAT-ZIP or hash a message with SAT-OBELISK, no install needed.

  3. 03

    Free to use

    Downloads are free, with no accounts and no ads. If something helps you, a coffee on Ko-fi keeps the lab running.

  4. 04

    Built in the open

    Even this site is part of the lab: a static site, its own API and a phone app to run it all.
