Platform capability

We build web apps on Next.js and React.

Next.js is the framework behind most of what we ship: SaaS platforms, dashboards, storefronts, and content sites. React and TypeScript on the front, a typed Postgres database on the back, deployed on Vercel.

In production
Talk about a web build

Can Foundri build our web app on Next.js and React?

Yes. Next.js and React are our default web stack. We build full-stack web applications and SaaS platforms in TypeScript, with server-rendered React on the front end, API routes and server functions on the back, and a typed Postgres database. We deploy on Vercel with a preview build on every change, and you get the repository, the docs, and a clean handoff. It is a modern, well-supported stack with a deep hiring pool, so nothing we build locks you in.

This is our default web stack, in production across client work and our own products. It is mature, well supported, and easy to hire for, which is exactly why we reach for it first.

Two shapes a web build takes

Most web work is one of two things, and they carry different risks. We settle which one you are building before we start.

Full-stack product

App

A real application with accounts, a database, and logic that has to be right.

Language
TypeScript, React, and the Next.js App Router
How it ships
Deployed on Vercel with a Postgres database and a preview URL on every pull request.

What it gives you

  • Server-rendered React with the App Router
  • API routes and server actions
  • Typed Postgres through an ORM (Drizzle or Prisma)
  • Auth, payments (Stripe), and email (Resend) wired in
  • Background jobs and scheduled tasks

What you can do with it

  • Multi-tenant SaaS platforms
  • Dashboards and internal tools
  • Storefronts with cart and checkout
  • Anything with users, data, and real logic

Pick this when

You are building a product, not a brochure. Accounts, a database, and logic that has to hold up.

Content and marketing site

Site

A fast, findable site backed by markdown or a headless CMS, that plugs into your product later.

Language
TypeScript, React, and Next.js
How it ships
Statically and incrementally rendered, deployed on Vercel.

What it gives you

  • Markdown/MDX or a headless CMS
  • Static generation and incremental revalidation
  • Structured data and SEO built in
  • Analytics and forms

What you can do with it

  • Marketing sites that load fast and rank
  • Blogs and documentation
  • Campaign landing pages

Pick this when

You need something fast, findable, and easy to update, and it should share a codebase with your product.

What we build on this stack

  • SaaS platforms and multi-tenant products
  • Customer dashboards and internal tools
  • Storefronts with cart, checkout, and payments
  • Marketing and content sites that plug into the product
  • APIs and backends that serve web and mobile from one place
  • AI features wired into the product

Our approach

We pick boring, well-supported tools on purpose. Next.js, React, TypeScript, Postgres, and Vercel are proven, documented, and easy to hire for, so your product is fast to build now and cheap to maintain later. We keep the codebase typed end to end, ship behind preview URLs so you see every change before it goes live, and hand you a repository you fully own.

How a web build runs

  1. 1

    Scope and shape

    We pressure-test the idea, cut it to the core that proves the point, and agree on scope and a plan.

  2. 2

    Design in the open

    Product and UX design you can react to early, not a reveal at the end.

  3. 3

    Build in weekly slices

    Working software every week behind a preview URL, so feedback lands while it is still cheap to act on.

  4. 4

    Launch on Vercel

    Go live with monitoring, backups, and a database ready for real traffic.

  5. 5

    Own it or grow it

    Take the clean repo to your own team, or keep us on to build the next thing.

What to know before you build

No stack is free of tradeoffs. Here is where Next.js asks something of you, said plainly.

It rewards a real backend
Next.js shines when there is a database and server logic behind it. For a pure static brochure with no product behind it, it can be more than you need, and we will say so.
Server rendering has sharp edges
The App Router, server components, and caching are powerful but have a learning curve. Holding that is our job, not yours, which is why we keep the patterns consistent.
Vercel is our default, not a lock-in
We deploy on Vercel because it fits Next.js best. If you need another host or your own cloud, including AWS, we can target it, with some tradeoffs we will walk you through.
The ecosystem moves fast
React and Next.js move quickly. We stay on well-supported versions and avoid bleeding-edge features likely to churn, so upgrades stay boring.

Next.js & React questions, answered

Is Next.js a good choice for a SaaS product?
Yes. It is one of the most common stacks for modern SaaS, and it is our default. You get server-rendered React, API routes, a typed database, and a deep hiring pool, so the product is fast to build and easy to maintain.
Do we own the code?
Completely. You get the repository, the docs, and a clean handoff. Nothing is locked to us.
What database do you use?
PostgreSQL by default, through a typed ORM like Drizzle or Prisma. It is reliable, well understood, and runs anywhere.
Can you take over an existing Next.js or React app?
Yes. We join in-progress projects and rebuilds regularly. We review the existing code first and tell you honestly what shape it is in.
Does it have to be hosted on Vercel?
No. Vercel is our default because it fits Next.js best, but we can deploy to other hosts or your own cloud, including AWS, when that is a requirement.
Can this be the backend for our mobile app?
Yes. We regularly build a Next.js API and admin that serve both a web app and native mobile apps from one backend.
