Custom SaaS and web apps, built on a modern TypeScript stack.
When a marketing site isn't enough, we build the product. Stacklumen ships custom SaaS and web applications on a modern TypeScript stack — Next.js or Astro on the front, Supabase / Postgres and Stripe underneath, with auth, admin tooling, and observability built in from day one. Deployed to Cloudflare or Vercel, handed over with the knowledge to run it.

01 Who it's for
- You're building a product, portal, or internal tool — not just a website.
- You need auth, billing, a database, and admin tooling done right.
- You want a maintainable, type-safe stack rather than no-code lock-in.
- You're a founder or team ready to invest in real engineering.
02 What's included
- Next.js or Astro + TypeScript front end
- Supabase / Postgres database with Stripe billing
- Authentication, admin tooling, and observability
- Cloudflare or Vercel deployment and CI
- Knowledge transfer plus 60 days of post-launch support
03 How it works
- Discover. We map the product, data model, and must-have flows.
- Design. We design the UX and architecture before writing code.
- Build. We ship in iterations — auth, billing, core features, admin.
- Launch. We deploy, hand over the keys, and support you for 60 days.
04 The fine print
Good to know
Ongoing feature work after launch is best handled on a monthly retainer. The build gets you to a solid v1; the retainer keeps it growing.
