Why We Build on Next.js, TypeScript, and PostgreSQL

Every framework decision is a bet on what will still be maintainable — by us or by whoever inherits the codebase — three years from now, not just what ships fastest this quarter. That's the filter behind standardizing on Next.js, TypeScript, and PostgreSQL rather than picking whatever's newest for each new engagement.

Next.js earns its place because it's one of the few frameworks that treats both rendering strategy and SEO as first-class concerns rather than afterthoughts. Server-side rendering and static generation are built in, not bolted on with a plugin, which matters directly for Core Web Vitals and crawlability — the two things a marketing site or e-commerce storefront can't afford to get wrong. Its App Router also makes it straightforward to keep most of a page server-rendered and add client-side interactivity only where a page genuinely needs it, which keeps JavaScript payloads — and therefore INP — under control by default rather than by discipline.

TypeScript's value shows up less on day one and more on day two hundred. A marketing site with thirty content-driven pages, or a directory with a schema spanning agencies, industries, and locations, has a lot of surface area for a typo or a mismatched field name to cause a silent bug. Catching that at compile time, before it reaches a client's production site, is worth the modest overhead of writing types — especially on a codebase more than one person will ever touch.

PostgreSQL is the choice for anything that needs real relational data — a directory, a contact form's submissions, an admin dashboard's authentication. It's mature, well-documented, handles relational integrity properly through foreign keys and constraints rather than leaving that enforcement to application code, and has a long enough track record that hosting, backups, and tooling are all solved problems rather than open questions. Building on Supabase specifically adds a managed Postgres instance with authentication and row-level security already wired together, which removes a meaningful amount of infrastructure work without giving up the ability to run direct SQL when a project genuinely needs it.

None of this is a claim that other stacks are wrong — plenty of good sites run on other combinations. It's a claim that switching frameworks per project, chasing whatever's trending, trades short-term novelty for long-term maintenance cost, and that a smaller set of tools we know deeply produces fewer surprises in production than a wider set we know shallowly.
