When You Need an App, Not a Website.
Logins. Customer-specific data. Workflows that a form and a spreadsheet cannot hold. The moment your business crosses that line, most web agencies hand you off to somebody else. I build on both sides of it: marketing sites on Astro, applications on Next.js and Supabase, one partner accountable for both.
What I Actually Build When a Site Is Not Enough
Client portals and dashboards
The moment your customers need to log in and see their own data, you have left website territory. I build the portal: auth, per-user views, and the reporting behind it, wired to the systems you already run.
Auth and user data on Supabase
Supabase gives you a real Postgres database, authentication, and row-level security without inventing a backend from scratch. Your data stays queryable, portable, and yours, not locked in a SaaS tool that almost fits.
Next.js application architecture
For interfaces that are genuinely interactive, dashboards, multi-step workflows, internal tools, Next.js is the right tool. I use it where an application is the honest requirement, not as a default for pages that should be plain HTML.
Deciding which side of the line you are on
Half the value is the call itself: what belongs in the app, and what stays on the fast Astro marketing site. One partner across both means nothing gets built on the wrong side, and the two stay wired together.
My Take: The Expensive Mistake Is Building One With the Other's Tools
Businesses get sold apps when they need websites, and websites when they need apps. Both errors are expensive in the same way: an app built from website tools becomes plugin duct tape that breaks under real users, and a marketing site built like an app is slow for no reason. The fix is drawing the line deliberately. Your marketing site stays a fast hand-coded Astro build, and the application gets a real database and real auth instead of five SaaS subscriptions that almost fit.

The client reporting dashboard, in pilot
The worked example is the application I am building for my own clients: a reporting dashboard on exactly this stack, Next.js on the front, Supabase holding the data, where clients log in and see their leads, sources, and spend in one place instead of a monthly PDF.
Honest framing: it is in pilot with active clients today, not a polished product with a testimonial page. I am telling you about it because it is current proof that I ship on this stack, and I will publish it properly when it has earned a case study.

Everything I run is tracked and reported against the numbers your leadership team already cares about: qualified pipeline, cost per opportunity, closed-won revenue. You get a live dashboard plus a reporting cadence we set up front, so you see what was done, what it moved, and what it cost. And when a channel can't earn its budget, I say so.
Not sure if you need a site or an app? That's the call to book.
