Web App & SaaS Development
Custom web applications and SaaS products — from MVP to production-ready platform. React, Laravel, Node.js, and AI integrations.
Web app and SaaS development builds custom web applications — dashboards, portals, subscription platforms and APIs — with authentication, billing and scalable architecture. Projects typically range from $6,000 for an MVP to $26,250+ for a full SaaS platform, depending on features and integrations. ReStartWeb AI has built custom web apps since 2016.
We build web applications that solve real business problems. Whether you're validating an idea with an MVP or scaling a SaaS product to thousands of users, we deliver clean architecture, comprehensive API coverage, and production-grade reliability.

How We Work
Product Discovery
We translate your idea into a technical specification: user stories, data models, API contracts, and infrastructure plan. No ambiguity before code is written.
UX & Architecture
Figma prototypes for all user flows + technical architecture document. Database schema, API structure, and third-party service selection finalized.
Iterative Development
Two-week sprints with weekly demos. Feature-by-feature delivery so you can give feedback early and adjust scope before it's expensive to change.
Launch & Scale
Production deployment, load testing, monitoring setup (Sentry, Datadog), user documentation, and ongoing development retainer.
