I've been building an open-source framework called Akan.js and wanted to share it here, partly because I'd like feedback from people who care about how these things are licensed and structured, not just whether they're shiny. The problem it targets: for a single feature, you usually end up maintaining something like 8 separate layers. Schema, query, service, API, fetch client, types, state, UI props. Codegen tools and AI assistants can produce all of those quickly. What none of them do well is keep the 8 in sync when you change one thing three weeks later. The web version and the mobile version drift apart, and you find out in production. Akan.js takes a convention-over-configuration approach to that. You declare a feature once: export class ProductInput extends via((field) => ({ name: field(String), })) {} and the framework derives the schema, type, API contract, fetch client, state, and UI prop from that one declaration, for web, iOS, Android, and the server. Change the declaration and the derived layers move with it. The conventions are doing the work, which is also why it stays legible to coding agents. There's less surface area for them to get wrong. Some honest details: It's Bun-first. That's a deliberate constraint, not a hedge. If you're on Node this is not a drop-in. Native iOS/Android is a Capacitor shell, not a from-scratch native renderer. I'm not going to pretend otherwise. What I did add at the framework level is page transitions (stack, fade, bottom-up, scale) so navigation doesn't feel like a website trapped in a webview. It's early for outside contributors. I've run it on internal projects and a handful of client deployments over about five years. What I'd genuinely like from here: Tell me where the architecture is wrong. Whether the single-declaration model holds up outside the cases I built it for. And if anyone has kept web and mobile in sync by hand and has opinions about where this breaks, I want to hear them before more people depend on it. Happy to answer anything!
