Custom Web & SaaS Application Development
In short
We design and ship full-stack web products and SaaS platforms your team owns outright — no per-seat licensing, no vendor lock-in. From multi-tenant architecture to billing and auth, built production-grade with a working demo before you pay.
Off-the-shelf SaaS forces your business to bend to someone else's product and pay per seat forever. A custom web or SaaS application is built around how you actually work, and you own the code, data and infrastructure outright. We deliver the whole stack — frontend, API, database, auth, billing and deployment — production-hardened and handed over cleanly.
What's included
- Full-stack delivery in Next.js, FastAPI or Astro with PostgreSQL, Redis, and clean REST or GraphQL APIs.
- Multi-tenant SaaS architecture, auth flows, billing integration, and role-based access out of the box.
- Production-hardened with Docker, Caddy, Cloudflare and systemd process management.
- Owned outright — source code, infrastructure and IP handed over, with no recurring license.
Proof
L&S Command Center — a custom platform with 50 data models and 380+ API endpoints, owned outright by the client.

Frequently asked questions
How much does custom web or SaaS application development cost?
Engagements are scoped per project rather than billed hourly, so you know the cost before work starts. A custom build is a one-time cost that becomes an asset you own, versus per-seat SaaS that recurs forever — over two to three years owning is usually cheaper. Start with the 1-Day Build for a concrete quote.
How long does it take to build a custom web application?
Simple tools can be live in days; a full-featured multi-tenant SaaS with billing, auth and integrations typically runs four to eight weeks depending on scope. A senior operator leads the build directly, and you see a working demo before you commit.
Do I own the application and its source code?
Yes — fully. You get the source code, repositories, infrastructure and all IP. We don't retain licenses or usage rights, and there's no per-seat fee. Owning it outright instead of renting it indefinitely is the entire point.
Next: Owned vs per-seat SaaS get a working demo before you pay
Ship a working demo before you pay a cent.
We scope it, build it, and hand you something live — within one business day. A $100 refundable deposit is all it takes to start. If the demo doesn't impress you, you owe us nothing.
