React, Supabase & Netlify SaaS Builds for UK Businesses
Building a SaaS product on the wrong stack wastes months and money. By Design UK combines React, Supabase, and Netlify into a production-ready architecture that scales from your first paying customer to thousands of concurrent users — all priced transparently, all delivered from our Enfield studio.

Why Is React, Supabase and Netlify the Right SaaS Stack for UK Founders?
This trio gives you a typed, component-driven frontend (React), an open-source Postgres backend with built-in auth and real-time subscriptions (Supabase), and globally distributed edge hosting with automatic CI/CD (Netlify) — without locking you into a single-vendor ecosystem. For UK founders under cost pressure, the stack eliminates expensive DevOps headcount in the early stages while remaining enterprise-ready when you scale. Our SaaS platform builds start from £18,000 and extend to £650,000+ for multi-tenant enterprise products, meaning the architecture fits every budget tier we serve.
What Does By Design UK Actually Build on This Stack?
We design, engineer, and launch full SaaS platforms — not MVPs cobbled together from no-code tools. A recent live example is Tackly.co.uk, a SaaS platform we built that now serves 25 distinct industries. Tackly demonstrates our ability to handle multi-industry data models, role-based access control via Supabase RLS policies, React dashboards with real-time updates, and zero-downtime deployments through Netlify pipelines. Every project we take on follows the same engineering discipline.
How Much Does a React and Supabase SaaS Platform Cost in the UK?
Costs depend on feature complexity, user-role requirements, and integration depth. Our fixed pricing tiers give you a clear starting point:
- Starter SaaS build — from £18,000 (core auth, single tenant, up to 10 screens)
- Growth SaaS build — from £45,000 (multi-tenant, billing integration, admin panel)
- Scale SaaS build — from £95,000 (API marketplace, analytics, enterprise SSO)
- Enterprise — from £150,000 to £650,000+ (bespoke architecture, dedicated infrastructure)
After launch, our monthly support plans from £797/month cover hosting management, Supabase database monitoring, security patches, and iterative feature releases — so your platform never stagnates.
What Is Included in a By Design UK SaaS Build?
Every engagement covers discovery and technical scoping, UI/UX design in Figma, React frontend development with TypeScript, Supabase schema design and RLS policy configuration, Netlify deployment pipeline setup, automated testing, and a structured handover with full documentation. We do not offshore development; your project is managed and built by our Enfield-based team, giving you a single point of accountability and direct phone access on 020 3951 4908.
How Long Does a UK SaaS Build Take with This Stack?
A starter-tier build typically ships in 10 to 16 weeks. Growth and Scale projects run 20 to 36 weeks depending on third-party integrations. Enterprise engagements are scoped individually. The Netlify and Supabase combination reduces infrastructure setup time significantly compared to AWS-native stacks, which is part of why our delivery timelines are competitive for a fully custom product.
