Web App Development

Affordable Web App Development

Senior-quality web apps without the senior-agency price tag. Our AI-assisted vibe coding workflow cuts the boilerplate hours that inflate most development quotes — passing the savings to you.

Where the Cost of Web Development Actually Goes

Traditional development agencies bill $150-$250/hour for work that is largely repetitive: setting up auth boilerplate, writing CRUD endpoints, building standard form components, configuring deployment pipelines. This work follows the same patterns on every project — it's not creative problem-solving, it's scaffolding. Our AI-assisted workflow handles this category of work in a fraction of the time. The scaffolding that used to take three days takes three hours. Senior engineers review and refine every output, but the raw clock time — and therefore the cost to you — drops dramatically.

Hourly billing creates a structural misalignment between what you want (a finished product) and what the vendor invoices (time spent). A slow engineer who rewrites a component three times bills more than a fast engineer who gets it right the first time. We don't bill hourly. We quote fixed prices for fixed scopes. If we scope incorrectly and the work takes longer than estimated, that's our problem, not yours — you pay what was quoted.

Affordable doesn't mean offshore. Low-rate offshore development often has a hidden cost: communication overhead, timezone delays, and rework from misunderstood requirements. We've seen clients spend $8,000 on offshore work and then pay $12,000 to have it rebuilt. Our projects are done by senior engineers who speak your language, work in your timezone, and understand what 'launch this before Monday' actually means.

Our Approach to Affordable web app development

Every project follows our 4-step vibe-coding process — AI handles the boilerplate, senior engineers handle the craft. From idea to live product in 3–7 days for MVPs.

01

Tight Scope Definition

Affordable development starts with a tight scope. We run a discovery session to identify the 20% of features that deliver 80% of the value, define clear acceptance criteria, and quote based on that scope — not a wish list.

02

AI-Assisted Scaffolding

We use AI to generate auth systems, API routes, form validation, and data table components at a fraction of the time it would take to hand-code them. Senior engineers review every line — the AI handles the pattern, the engineer handles the judgment.

03

Pre-Built Starter Infrastructure

Every Greta project starts from a battle-tested Next.js starter with auth, database migrations, Stripe integration, email, and deployment already wired up. You're not paying for us to configure Supabase from scratch for the 50th time.

04

Fixed-Price Invoicing

The price we quote before the project is the price on the invoice. Scope changes require a written change order with a new fixed price. No invoice surprises, no timesheet disputes, no 'that took longer than expected' conversations.

What You Get

Every affordable web app development engagement includes these deliverables — scoped before we start, delivered before we invoice.

  • Authentication system (email, OAuth, or magic link)
  • Core data model with PostgreSQL migrations
  • 3-5 key application screens with responsive design
  • Server actions or API routes for core business logic
  • Stripe payment or subscription integration (if in scope)
  • Production deployment on Vercel with custom domain
  • Error monitoring via Sentry
  • Source code in your GitHub repository
  • Basic documentation: how to run locally and how to deploy
  • 2-week post-launch bug-fix support

Tech Stack We Use

Affordable doesn't mean cut-rate tooling. We build on the same stack for every budget: Next.js 15, React 19, TypeScript strict mode, Supabase, Stripe, Tailwind CSS, and Vercel. What changes with budget is scope — the number of screens, integrations, and custom features — not the quality of the underlying engineering or the care taken with the architecture.

Case Study

SEO Pilot — Under $10K, Generated $40K+ in Pipeline

The founders of SEO Pilot had a precise brief: a content research and publishing tool for SEO writers, with a free tier and a paid upgrade. They'd been quoted $45,000 by one agency and $32,000 by another. Both quotes included six weeks of timeline. Greta scoped the MVP tightly — auth, a research workspace, a content editor, a publishing queue, and Stripe checkout — and delivered for under $10,000 in 5 business days. Within 90 days of launch, the tool had generated over $40,000 in pipeline from inbound signups attracted by the content the tool itself helped produce. The ROI conversation was straightforward.

Frequently Asked Questions

What does the $4,000 MVP tier actually include?

Auth (email and one OAuth provider), a core PostgreSQL data model with migrations, 3 application screens responsive across desktop and mobile, server-side business logic, production deployment on Vercel, and a 2-week bug-fix window. Stripe payments and additional screens are priced as additions.

How do you keep costs low without sacrificing quality?

Our AI-assisted development workflow handles boilerplate generation at a fraction of the time it would take to hand-code. We also start from a pre-built starter kit so you're not paying us to configure Supabase auth or set up ESLint from scratch. The savings come from efficiency, not shortcuts.

Is there a risk that cheap development means technical debt?

There is with some providers. At Greta, the same engineers who build your product are the ones who would have to maintain it — so we have a direct incentive to write clean code. TypeScript strict mode, Zod validation, and ESLint run in CI on every commit. We don't ship what doesn't pass.

How do you compare in cost to offshore development?

Low-rate offshore development quotes $5,000-$8,000 for work that takes 3-4 months and often requires expensive rework. Our $4,000-$5,000 projects take 3-7 days. The total cost of an offshore project — including rework and the 3-month delay — is typically higher than our fixed price.

What if my project scope grows after we start?

Scope additions are welcome but require a written change order before work starts. We quote the addition at a fixed price, you approve, and we add it to the timeline. There's no hidden cost to asking — only if you say yes.

Do you offer payment plans?

Standard payment is 50% upfront and 50% on delivery. For projects over $8,000 we can discuss milestone-based payment with three installments. Contact hello@greta.agency to discuss.

How do I know I'm getting what I paid for?

You have access to the GitHub repository and staging environment throughout the project. You can run your own Lighthouse audit, review the code, or share the staging link with your technical advisor at any point. We welcome scrutiny.
