The evidence

Our standard, in public.

qb is a C++20 actor framework we build, run and answer for. Read the code before you decide whether to trust the people who write it.

Fork it, benchmark it, file an issue. Then bring us a system where “fast enough” has a number attached to it.

What we publish

github

qb

The framework. Share-nothing actors over a non-blocking I/O runtime, with native C++20 coroutines. The I/O layer stands alone if the actor engine is more than you need.

The protocols ship as separate repositories rather than inside the core, so a project takes only what it uses. Everything above is public, versioned, and running in production.

We maintain these under production load, which is also how we know what they cost to operate.
