Products

The tooling behind our speed.

We build on our own in-house products, an advantage most consultancies don't have: client work starts at speed, on foundations we trust because we live on them.

01 / Full-stack template

Onyx

In production use on every engagement

A proven starting point, so client work begins at product speed, not from scratch. Every engagement hardens it further.

02 / Product management suite

Quartz

Runs every JXD engagement

Issues link to the commits that close them, notes link to the decisions they record, and clients see the same view we do.

03 / Data compliance framework

Garnet

Runs the policies on this site

Policies as maintained artefacts with owners, history, and evidence, mapped to real systems instead of a PDF nobody reads.

04 / AI simulation engine

Sapphire

Runs our own architecture decisions

Simulated engineering teams stress a decision before you make it: which stack fits your team, what breaks at scale, and which assumptions fail first.

05 / REST client and test suite

Amber

Tests every API we ship

A REST client built on Markdown: requests are version-controlled, diffable, and executable, so the collection you explore an API with doubles as its test suite in CI.

06 / Open-source CMS

Stet

Self-host it, or run it on our cloud

Marketing adds a field in the interface and the developer's editor autocompletes it seconds later. Marketing deletes one and the build stays green.

07 / Open source

Built for us, released for everyone.

When the official tooling falls short, we build our own and publish it. MIT licensed, maintained, and tested in CI. More on the way.

Companies House SDK@jxdltd/companies-house

A typed TypeScript SDK for the Companies House Public Data API. All 34 endpoints, zero dependencies, generated from a curated OpenAPI 3.1 spec and verified against the live API daily.
