Cirkl Labs

We are a security research company, our website is cirkl.ai

We care a lot about privacy, so we are creating an antivirus that doesn't spy on you or give you annoying popups.

And we're creating a web browser that doesn't treat you like a product while keeping you safe from malware and trackers.

Nerdy stuff

Our favorite languages (in no specific order):

C++-Really fun, and it's quite splendid for low-level code, also multithreadding is easy peasy compared to C
Zig-Fun to learn, good for high-performance and low level control with enhanced safety
Kotlin-Really, REALLY nice with the Ktor framework, it makes API insanely easy (also mobile apps with KMP)
JS-Absolutely terrible but also amazing
TS-JS but with types ;) (still a pain)
Dart-Really nice, performant and simple language with a familiar syntax and easy to make APIs in and software in general.

Our favorite technologies

Anything from JetBrains-IntelliJ has saved my brain, CLion saved my legs
macOS-Beautiful UI, amazing stability (update: macOS 26 is horribly buggy and also really nice)
Linux-Amazing on the server, amazing on the Desktop

Things I hate with a burning passion:

VSCode-Electron is slow and VSCode is no exception, it's massive on a drive and in memory
Electron-people dont know how to properly optimize it, I hate electron apps but not Electron itself (usually)
People who say C++ is unsafe and Rust is better-I like both, please just leave it at both are good, both have up's and down's!
GTK (On windows)-GTK looks pretty, it's a shame it's an ABSOLUTE PAIN to get working on Windows! Oh, speaking of...
Windows—Terrible os, AI infested + most games do work on linux, thanks to valve! It also doesn't even look that good and its super buggy; I have no idea how people survive on Windows.
Me-I create Most of the problems I encounter.
Oracle-Breh, release the JS trademark already (Deno v. Oracle)

Things I love with the power of a thousand suns:

Note: The not all of the above languages in this section are in use at Cirkl, I just personaly like them ;)
