Reliability Tooling
Chaos & Verification Harnesses
Test harnesses for failure injection, shadow-traffic diffing, and cutover verification, generalized from engagement work.
We build on open source. We build it back
Every system we ship stands on open infrastructure. This registry documents how we engage with that ecosystem: the principles we follow, and the areas where tooling from our engagements is generalized and released.
Engagement Principles
How we participate
01Upstream First
Fixes and improvements to the libraries we depend on go back upstream, not into private forks that rot.
02Clean Licensing
Every dependency in a client system is license-audited. Releases from our own work ship under permissive licenses.
03Responsible Disclosure
Vulnerabilities we uncover during audits are reported privately to maintainers and disclosed on their timeline.
04Maintainer Support
We sponsor and contribute engineering time to the critical projects our production stacks are built on.
Release Pipeline
Tooling focus areas
Where client-funded engineering is generalized into reusable tooling, subject to IP agreements and security review before any public release.
Data Infrastructure
Streaming Pipeline Utilities
Connectors, schema-migration gates, and replay tooling for change-data-capture and event-stream pipelines.
Performance
Profiling & Benchmark Kits
Reproducible load-generation and flame-graph tooling used in our architectural audits, packaged for general use.
Maintain a project we should be supporting?
If your project sits in one of our production stacks, we would like to hear from you, for sponsorship, contribution, or coordinated security work.
