Open Source

We publish parts of our low-latency I/O and real-time communication work as MIT-licensed open source packages at code.hybscloud.com.

Through these packages, developers can see how we design Go systems: keeping runtime behavior clear while building practical abstractions for real-time applications.

Focus

Our open source work is centered on three areas.

• Low-latency I/O and real-time communication
• Go components whose runtime behavior is visible in source code
• Systems programmability: explicit I/O results, resource lifecycle, buffer and queue pressure, completion handling, and protocol steps

Package Areas

Runtime Primitives

zcall, iofd, sock, and framer provide direct building blocks for syscalls, file descriptors, sockets, and message framing.

iobuf, lfq, spin, atomix, and dwcas support buffer reuse, lock-free queues, short-wait policy, and atomic state transitions.

Linux I/O and Runtime Composition

uring provides a pure Go interface to Linux 6.18+ io_uring. It keeps submission context, completion results, buffers, multishot state, and zero-copy notification state available to higher-level code.

Computation and Protocol Structure

iox, kont, cove, takt, and sess model I/O outcomes, suspended computation, context evidence, completion-driven system steps, and protocol steps.

For Developers

For developers evaluating a real-time project, this open source work is a practical way to understand our technical stack before a deeper conversation with us.

You can review the source code, evaluate the design, and see whether an open, Go-based real-time foundation fits your project, platform, or internal engineering direction.

The packages are building blocks and reference implementations. Real projects still need design, integration, and operational choices specific to the project.
