The Cylch Framework

One codebase. Every platform.

Cylch (Cymraeg for "circle") is our in-house cross-platform framework - a single, modular codebase written in C# and TypeScript that ships to web, mobile, and desktop without the rebuild.

Battle-hardened in real-world production since 2021, Cylch has powered everything from rapid prototypes to complex enterprise platforms. Most of the client and partner work you see across this site was built on Cylch, or a partner-licensed variant - and we keep refining it with every release, guided by feedback from real deployments.

Out of the box, Cylch arrives pre-loaded with the engineering best practices, design patterns, and tooling our teams rely on - so you get clean, maintainable, standards-led code without the groundwork.

bolt

Go to market sooner

Reusable modules and proven patterns cut development time - and cost - without cutting corners.

sync_alt

One source of truth

Write once, deploy to web, iOS, Android, Windows, macOS, and Linux from a single maintainable codebase.

handshake

Built by developers, for developers

Cylch is written by the same engineers who ship our client work - shaped by production reality, not theory.

account_tree

Make Cylch your own

Extend Cylch into a framework tailored to your agency. We already help partner teams build on its proven foundation, accelerate delivery, and launch products under their own brand.

devices

Cross-platform by design

Reach every screen from one codebase - web, native iOS & Android, and native Windows, macOS, and Linux desktops. A wider audience, one source of truth.
verified_user

Secure from day one

Authentication, authorisation, and data protection are built in, not bolted on - with configurable security options designed for GDPR compliance from the start.
fingerprint

SSO with confidence

SAML, OpenID Connect, or OAuth2 - Cylch makes single sign-on and identity management plug-and-play, so users sign in seamlessly with Microsoft, Apple, Google, and more.
rocket_launch

Prototype to production

Turn a proof of concept into a full product without a rewrite. Cylch scales from first prototype to enterprise deployment on the same foundation.
extension

Modular and maintainable

A modular architecture that grows with you. Swap, extend, or replace components without destabilising the platform - your codebase stays clean as your product grows.
military_tech

Proven under fire

In production since 2021 across client and partner builds - prototypes, enterprise platforms, and everything between. Refined by real-world feedback, not guesswork.
