Introduction

Welcome to the Ark documentation.

What Ark is​

Ark is a middleware framework that bridges legacy platforms and modern solutions, so banking organisations can integrate them without a full digital transformation.

It pairs a composable, modular architecture with prebuilt connectors that automate workflows, optimise operational efficiency, and improve customer experience — with a particular focus on helping mutual banks deleverage their core banking systems onto modern infrastructure.

How this site is organised​

  • Concepts — high-level explanations of how Ark fits together, written from the outside in. Start with Multi-tenant, multi-connector.
  • Guides — per-element walkthroughs: Ark Platform, Ark Flows, the Business Rules Engine, and each connector.
  • Architecture — the architecture set under docs/architecture/ in the repo, surfaced here as its own section.
  • API Reference — interactive reference generated from the OpenAPI specs in openapi/bundle/.
  • Changelog — release notes, by version.
