Reference platform · v1 in active development
A UK retail bank you can run — without being one.
Malai is a complete reference platform for prospective bank operators: a banking core, customer portal, marketing surface, and infrastructure-as-code — wired together so you can evaluate the architecture, license what works, and commission what's missing.
For platform architects, security & compliance reviewers, and commercial buyers evaluating a modern UK banking platform.
How Malai Works
Four repositories. One coherent platform.
Each app is independently buildable and individually licensable. They share a single typed API contract and one design system.
-
malai-backend
Banking core
Banking-grade API with double-entry ledger, hash-chained audit log, idempotent mutations, and standards-based session auth. The piece bank technologists will read line-by-line.
-
malai-webapp
Customer portal
Typed single-page app with Confirmation of Payee, idempotent transfers, and the UK realism details — sort code formatting, Faster Payments microcopy, GBP throughout.
-
malai-website
Marketing surface
Static, SEO-strong B2B site (this site) hosting the architecture story, security posture, and the live demo entry point. Pre-rendered HTML; interactive islands only where they earn it.
-
malai-infra
Infrastructure-as-code
Per-environment Terraform footprint covering network, container platform, managed database, secret store, and CDN. A fresh environment stands up in minutes from a clean cloud account.

Three ways in.

For platform architects
A complete cloud-native platform you can read end-to-end: enforced module boundaries, a typed API contract, double-entry ledger, three-pillar observability, and infrastructure-as-code that spins up a fresh environment in minutes.
