Software craftsmanship taken to perfection.
Xorio is a Rust & STEM open-source collective. We craft innovative solutions in Rust and other safe languages — Kotlin, Go, Python, Flutter and Java — with collaboration and transparency at the core, focused on high-performance systems, robust web services and secure applications.
High-performance systems
Systems software in Rust — filesystems, distributed storage, encryption and OS-level tooling built for speed and safety.
Robust web services
Backends and APIs with gRPC, REST, tonic and serverless stacks — engineered to stay up and stay fast.
Secure applications
Security-first software: encrypted filesystems, cryptography, zeroized memory and safe-by-construction design.
Open-source collaboration
Everything is built in the open — public repos, public roadmaps, and contributors welcomed at every level.
Our best-known project is rencfs — an encrypted filesystem that mounts with FUSE, named Rust crate of the week in August 2024. Around it grew a whole family: SyncOxiders for cloud file sync and encryption, rfs for distributed filesystems, desktop and daemon frontends, Python bindings and more — 30+ projects, all listed in the gallery.
Learn
We organize several free and open-source courses because we want to be the mentors we didn't have — it's also one way we give back to the community. Join Discord and choose the courses you're interested in — details in the #courses channel.
Mentor
If you want to be a mentor and help others grow, you're among the right people. Join Discord — the #i-am-a-mentor channel explains how to get started.
Talks & coding challenges
Periodic in-person and online talks and coding challenges keep you up to date with the latest tech and sharpen problem-solving. Announced in channels like #coding-challenge; events are organized on Meetup with *Tech-RD (Star Tech RD Reloaded), and we build alongside Forge Baia Mare at their monthly meetup.
Many of our experiments have no contributors yet — you could be the first. If you want to ship a feature, mentor, or just learn in the open, there's a seat for you.
Forge Baia Mare
A free monthly meetup in Baia Mare for everyone who builds — developers, designers and makers alike. No speakers, no badges, no networking format: an open floor at BASE coworking where people pair up, bring the project they're stuck on and ship together. Build together. Learn together. Ship together. forgebaiamare.ro ↗
*Tech-RD — Star Tech RD Reloaded
A long-running Romanian tech community with regular talks on Rust, AI, DevOps, Flutter, algorithms and more — friends, beer, snacks and, most important, tech talks. Our own talks and coding challenges are announced through their events. startech-rd.io ↗ Meetup ↗
In 2024, Radu was the 5th most active GitHub user in Romania — and the first for Rust language.
