Citadel
Local-first personal app hub: one host app running isolated mini-apps like Smart Notes, Gym Tracker, and more.
Citadel screens (8)
Overview
Citadel is a local-first app hub designed to run multiple personal tools under one roof while keeping each app isolated. It uses a single Next.js host with per-app SQLite databases, per-app storage roots, deny-by-default permissions, and audit logging. The result is a practical “apps inside an app” setup where new modules can ship quickly without losing safety boundaries.
Problem
Personal tools are easy to build but hard to keep organized. Citadel explores a host-app pattern where each utility can move quickly without sharing more data or permissions than it should.
Outcome
A working local-first app platform that shows how small tools can be bundled without turning into one tangled product.
