Step 01
The thesis — build, don’t buy
The whole idea in one line. Once you can drive Claude Code, you stop waiting for a SaaS feature and build the exact view you need.
Guide · Build vs Buy
I replaced 7 SaaS tools with one app I built.
Software stopped being something you buy — it became something you build. "The Hub" is a single Next.js app that replaces seven separate SaaS products: content, accounting, health, automation monitoring, subscriptions, travel, and meetings. Every dashboard is a thin UI over one database table and one data source, with an LLM doing the messy parsing a paid product would normally charge you for. This guide walks the repeatable architecture so you can build your own in an afternoon.

Prerequisites
What you need before you start
01 · Claude Code
Drove every dashboard, schema, and integration module in this guide.
02 · Next.js 16 + React 19
One app, App Router. Each dashboard is one route folder under src/app/.
03 · Supabase
Postgres + storage + auth backing for every dashboard. Service-role key server-side only.
04 · OpenRouter
One HTTP endpoint, swappable models. Cheap model to extract, stronger model to generate.
05 · API keys per source
Only for the dashboards you build: IMAP, Garmin, n8n, Apify, logo.dev, etc.

Step 02
The repeatable 5-part architecture
This is the core lesson. Every dashboard follows the same five parts — learn it once, ship a new dashboard in an afternoon.
