Custom app development for founders who need exactly what they built
Web app development for startups, scale-ups, and founders who outgrew templates. Built on modern stacks (React, Next.js, TypeScript, Supabase), tested in production, handed to you clean.
250+ projects shipped
Who this is for
If any of this sounds like you, we should talk.
You tried no-code and hit the ceiling
Webflow, Bubble, or Zapier got you to v0.1. Now you need real business logic, custom integrations, and a codebase you can scale. Time for a developer.
You have a feature only a custom app can solve
Your workflow is unique. Off-the-shelf software does not fit. You need something purpose-built for how you actually work.
You are raising and investors want to see production code
Demo works. Unit economics work. Now you need a codebase that scales, is secure by default, and does not make the first engineer run screaming.
You have existing users and the app is slowing you down
V1 was a hack. It worked. Now it is fighting you. You need someone to stabilize the code, add the features your customers are asking for, and keep shipping.
What changes for you
Outcomes you can point to, not features you can ignore.
- A custom app that solves your exact problem, not a templated compromise.
- Production-grade code on modern stacks (React, Next.js, TypeScript, Supabase, Stripe).
- A codebase you own outright. No licensing, no lock-in, no surprises.
- An app that survives 10x growth without a complete rewrite.
- Clean handoff to your own team or a care plan to keep us on retainer.

- Fixed timeline and milestone breakdown
How an engagement works
From hello to handoff, step by step.
You book a discovery call
We talk through what you are building, why, and who is paying for it. We ask hard questions about scope and timeline.
You get a proposal within 48 hours
Fixed price, fixed timeline, fixed scope. Everything is written down. No surprises at sprint eight.
We build in 2-week sprints
Every sprint ends with a real feature on staging. You can click through it, use it, give feedback.
You get weekly demos and updates
Every Friday, a 15-minute demo of what shipped that week. Async written update. No vague status reports.
We launch and hand off
Deployed to production, docs written, repo handed over, 30 days of support. You decide what comes next.
Case study
SCRAPD Marketplace
- Problem
- A upcycled fashion marketplace founder had a Figma file and zero technical infrastructure. They needed a real platform where sellers could list inventory, customers could browse and buy, and they could take a cut of every transaction.
- What we built
- We built a multi-vendor marketplace on Next.js and Supabase with Stripe Connect for seller payouts, role-based access (seller, buyer, admin), and an admin dashboard for marketplace operations.
- Result
- Live, revenue-generating marketplace shipped from Figma to live customers in under 10 weeks. Sellers onboarding weekly. Real transactions flowing through Stripe Connect.
Why us
What you get with WitsCode that you don't get elsewhere.
We ship scalable production code, not startup theater
Error handling, logging, monitoring, database indexing, security. All the boring parts that separate a demo from something 1000 users can actually use.
Modern stack by default, boring by choice
React, Next.js, TypeScript, Supabase, Vercel. Proven patterns that let you hire senior engineers and ship fast. No framework roulette, no experimental stacks.
We respect your codebase and your roadmap
You own the code. You own the repo. You decide what happens next. We can hand off to your team, stay in a care plan, or disappear. Your call.
WitsCode rebuilt our Shopify store so it finally converts the traffic we were already getting. They understand speed and storytelling in equal measure, and the store has been a real growth lever since launch.
