SaaS Development

SaaS Product Development

From wireframe to live SaaS product — in as little as 8 weeks.

Building a SaaS product is fundamentally different from building a one-off application — it requires thinking about multi-tenancy, billing, onboarding, role-based access and long-term maintainability from the very first architectural decision. StackLab's SaaS practice covers the full lifecycle.

FAQs

How does StackLab deliver SaaS so quickly?

We use a small, accountable team with a proven architecture pattern for SaaS products — multi-tenant database design, pre-built auth and billing infrastructure, and a weekly delivery process that surfaces decisions early. No layers of project management between the client and the engineers building the product.

Do you handle hosting and DevOps?

Yes. We architect and deploy on AWS or Vercel, set up CI/CD pipelines, configure monitoring, and handle infrastructure scaling as part of the engagement.

Can we own the code at the end?

Yes — all code is fully owned by the client. We do not use proprietary frameworks or license-locked components. You have full access to the repository and can take it to any team afterwards.

Do you build both web and mobile SaaS?

Yes. We deliver web-based SaaS with React/Next.js and mobile companions with React Native, either as part of an initial build or as a subsequent phase.
