Centrion.
Building the foundations of software.

Centrion develops browser engines, programming language tools, local decision systems, and Linux infrastructure. We work on the layers that other software depends on.

Explore five projects, each with its own purpose, implementation, and development status. Start with the problem you want to solve.

CENTRION / SELECTED WORK

Centrion Projects

Browser engines, developer tools, and products built around real problems.

5 selected projects

Featured project · Browser engine

Slate Engine

One of Centrion's most ambitious engineering projects: an independent, experimental browser engine built in Rust. Slate brings together custom HTML and CSS parsing, DOM and layout systems, SlaterMonkey JavaScript integration, network security policies, and offscreen rendering behind an inspectable engine API. Dedicated lifecycle, rendering, and conformance tests underpin an effort spanning language runtimes, graphics, and web standards. It demonstrates Centrion's ability to tackle the foundations of the web, from source markup to rendered pixels.

Language & compiler

Phage

An experimental programming language with its own parser, typed intermediate representation, diagnostics, and command-line tools. The toolchain checks and interprets a supported language subset, while a Cranelift backend lowers typed functions for JIT compilation.

Machine learning & decision systems

UDI Kernel

A local decision runtime built in Rust with Python training tools. UDI Kernel turns typed task definitions and JSON inputs into structured decisions, scores, and rankings through ONNX Runtime. Confidence thresholds, out-of-distribution signals, fallback decisions, and configurable policies connect model predictions to application behavior.

Local virtual machines

Capsule

A command-line tool for repeatable local Linux virtual machines. It creates QEMU-backed environments with cloud-init and managed SSH access, then supports snapshots, cloning, and portable archives for moving development environments between machines.

Container infrastructure

Cask

A Linux container runtime and local daemon built around runc and OCI images. Its command-line interface handles image pulls, container lifecycles, networking, logs, and resource configuration through a dedicated daemon protocol.
