Open Source

30 years of UNIX. Time to give some back.

Alongside our commercial safety-critical systems work, we contribute to the open source community that shaped us. The projects listed here apply the same principles as our production systems: mathematical rigour, minimal dependencies, and code designed to prove its own correctness.

Deterministic Computing GPL-3.0

certifiable-bench

Performance benchmarking for deterministic ML — because 'fast' means nothing if you can't prove it's correct

Deterministic ML GPL-3.0

certifiable-harness

End-to-end test harness for deterministic ML — because 'it works on my machine' isn't certifiable

Deterministic ML GPL-3.0

certifiable-verify

Pipeline verification for the certifiable-* ecosystem — because 'we checked it manually' isn't certifiable

Open Source GPL-3.0

certifiable-monitor

Deterministic runtime monitoring — because 'the model drifted' isn't certifiable

Deterministic ML GPL-3.0

Certifiable Deploy

Deterministic model packaging and cryptographic attestation — because 'trust me, it's the right model' isn't certifiable

Deterministic ML GPL-3.0

Certifiable Quant

Deterministic model quantization with formal error certificates for safety-critical ML

Education MIT

C-From-Scratch

Learn to build safety-critical systems in C — mathematical rigour, not 'Hello World'

Deterministic ML GPL-3.0

Certifiable Data

Deterministic data pipelines for safety-critical ML — because 'we shuffled the data' isn't reproducible

Security Monitoring MIT

C-Sentinel

Semantic observability for UNIX systems — lightweight system probing with explainable risk scoring
