Ship Fast, Ship Right

MVP Development

Working software on a staging URL within days. Fixed price. Full code ownership. Built to survive real users — not just a demo.

The idea is there. The market is ready. But somewhere between concept and code, most MVPs stall. Agencies take months to start. Freelancers disappear. No-code tools hit a wall the moment requirements get specific. The MVP never ships.

OneChair builds MVPs in days and weeks, not months. On production-grade infrastructure. With a fixed price agreed before we write a line. And a live staging URL so you can see it happening in real time.

What an MVP Actually Is

The word gets misused constantly. An MVP is not a prototype. It is not a wireframe. It is not a Figma file.

Definition

Minimum Viable Product

The smallest version of a product that real users can actually use — with working authentication, real data storage, functioning core features, and enough security that you are not embarrassed to share it.

A prototype tests a concept. An MVP tests a market. The distinction matters because one is built with disposable materials and the other has to hold up when a real user creates an account and enters real data.

We build MVPs. Not prototypes dressed up as MVPs.

Timeline: Days to Weeks, Not Months

Here is what our actual build times look like:

  • Cody Yellowstone — AI-powered travel planning app with itinerary generation, map integration, and user accounts. 12 hours of build time.
  • WellChild — HIPAA-compliant pediatric healthcare booking platform with 116 screens, multi-provider scheduling, and a clinical admin dashboard. 27 hours.
  • Resource Center — Content platform with user authentication, categorisation, and search. 30 hours.

Elapsed calendar time — including scoping, building, QA, and deployment — typically ranges from 3 to 14 days depending on complexity. Not 3 months. Not a sprint cycle.

What Every MVP Delivery Includes

There are no stripped-down deliverables. Every MVP ships with the full package.

What You Get

01

Live Staging URL

Your project is live on a real URL from day two of the build. You can click through it, share it with stakeholders, and watch it grow. Not a static mockup — real, running software.

02

Full Source Code

Private GitHub repository delivered at handover. Every file, every commit. No partial deliveries, no "we'll send the backend later." Everything at once.

03

Deployment Docs

Step-by-step deployment documentation and a recorded walkthrough of the architecture. Your team can take this and run it independently — no dependency on us.

04

Support Window

Post-launch support period included. Bug fixes, deployment questions, infrastructure queries — covered. Because shipping is the start, not the end.

The Honest Case Against No-Code Tools

Lovable, Replit, Bolt, and similar tools are genuinely useful for exploring ideas. We are not dismissive of them. But they have hard limits that become expensive problems.

Where They Work Well

  • Testing whether a concept is worth pursuing
  • Building a demo to show investors before a product exists
  • Creating internal tools with simple, predictable data flows
  • Rapid prototyping before writing a spec

Where They Break Down

  • Complex authentication flows with multiple roles and permissions
  • Custom data models that do not fit a generic table structure
  • Third-party integrations beyond what a pre-built connector supports
  • Compliance requirements (HIPAA, GDPR, PCI DSS)
  • Performance at scale — no-code platforms are not optimised for volume
  • Anything requiring custom business logic in the backend

The pattern we see: a founder uses a no-code tool to get something on screen, it works well enough to attract early users, and then it hits a wall. The rebuild starts from scratch, and the time saved upfront is spent twice over in the rebuild.

If your MVP is genuinely just a prototype — a thing to show, not a thing to use — no-code tools are fine. If it is a thing real users will rely on, build it on production code from the start.

Fixed Pricing — Why It Matters for MVPs

The most common MVP horror story is scope creep. A quote comes in at $15,000. The project ends at $45,000. By that point, the budget is gone and the product still is not ready.

Fixed pricing removes this dynamic entirely. Before any work begins, we audit your requirements and issue a single number. That number does not change. If something takes longer than we planned, we absorb that cost — not you.

The audit is where the work happens. We ask the questions that surface complexity before it becomes an invoice. An accurate quote depends on accurate requirements, so we spend real time on this before committing to a number.

Built to Scale — Not to Be Replaced

We build MVPs on the same production stack we use for full custom software projects: Next.js or React, NestJS or FastAPI, PostgreSQL, TypeScript throughout. There is no throwaway layer to remove when you grow.

When your MVP gets traction and you need to add features, you add them. You do not rebuild. The architecture is extensible by design.

Many clients move from MVP delivery directly into a technical partnership for ongoing feature development. The transition is natural because the foundation is solid.

Real MVP Builds

Cody Yellowstone — AI Travel Planner

A consumer app that generates detailed travel itineraries using AI, with map integration, day-by-day planning, and shareable trip links. The founder needed a working product to test market interest before raising a seed round. Built in 12 hours. Live on a staging URL by the end of day one.

WellChild — Healthcare Booking MVP

A pediatric healthcare booking platform with multi-provider scheduling, parent-facing flows, and a clinical admin dashboard. The client needed HIPAA compliance from launch, not as a retrofit. Built in 27 hours. 116 screens. Compliance-ready from day one.

Common Questions

A prototype is used to test an idea — it is not designed to go to real users. An MVP is a working product with real functionality, real data handling, and real security. It is the smallest version of your product that a paying customer can actually use. Prototypes are quick to build and quick to break. MVPs are built to survive contact with real users.

Tools like Lovable, Replit, and Bolt are excellent for getting something on a screen quickly. They break at production scale: no-code and vibe-coded apps typically hit hard limits around authentication complexity, custom data models, third-party integrations, and compliance requirements. If you are exploring an idea, they are fine. If you are building something users will rely on, you need production code.

Our real build times: Cody Yellowstone (an AI travel planning app with itinerary generation, map integration, and user accounts) in 12 hours. WellChild (a HIPAA-compliant pediatric booking platform with 116 screens) in 27 hours. Resource Center (a content platform) in 30 hours. Most MVPs complete in 1–2 weeks of elapsed time.

Every MVP delivery includes: all source code in a private GitHub repository, deployment to a staging environment (live from day two of the build), production deployment documentation, a recorded walkthrough, and a post-launch support window. You own everything — no ongoing licence fees, no lock-in.

Yes. We build MVPs on the same production-grade stack we use for full custom software: Next.js, NestJS, PostgreSQL, TypeScript. There is no rebuild required when you grow. The architecture is designed to extend, not replace. Many clients move from MVP directly into a technical partnership engagement for ongoing feature development.
