How Much Does a
Website or Web App Cost?
It Depends on Scope

Website cost comes down to what the site has to do. A marketing site and a logged-in web app are very different builds. We don't sell hours, we sell outcomes. Managed development starts from $75 per hour, and dedicated engineers run $50 to $150 per hour. A free build plan gives you one fixed price.

How We Work

Outcome-Based Pricing

We don't sell hours — we sell outcomes. Every engagement starts with a clear scope, defined deliverables, and upfront estimates so you know exactly what you're getting before work begins. Rates range from $50 to $150/hr depending on the seniority and specialization of the engineers on your project. You get full accountability, transparent progress, and a team that's committed to shipping results — not burning through a budget.

Scoped Upfront

Every project starts with clear deliverables, timeline estimates, and success criteria — before a single line of code is written.

Full Accountability

We own the outcome, not just the hours. Transparent progress updates, milestone reviews, and a commitment to shipping what we promised.

Flexible Engagement

Managed development with a dedicated team, or senior engineers embedded in yours. Scale up or down as your project evolves.

What Shapes Website Cost

The things that move a web project's budget most.

Site or Web App

Accounts, data and workflows make a web app a bigger build.

  • Marketing site
  • Customer portal
  • SaaS product
  • Internal tool

Page Templates

Unique layouts drive more of the cost than total page count.

  • Home and landing pages
  • Service pages
  • Blog
  • Case studies

Integrations

Each connected system adds work and testing.

  • CRMs
  • Payments
  • Booking
  • Analytics

Content and CMS

Who writes, migrates and edits content matters.

  • CMS setup
  • Content migration
  • Multi-language
  • Editorial workflow

Speed and SEO

Performance and search structure are built in, not bolted on.

  • Core Web Vitals
  • Structured data
  • Redirects
  • Metadata

Website Cost Questions

How much does a custom website cost?

It depends on the number of templates, your content, your integrations and whether you need logged-in features. Slashdev's managed development starts from $75 per hour, and dedicated engineers run $50 to $150 per hour. Our free build plan gives you a fixed price before any code is written.

What's the difference between a website and a web app?

A website mostly shows content. A web app has accounts, data and workflows, so it needs a backend, more testing and more ongoing care.

Do I need a custom build, or is a website builder enough?

If you need a simple marketing site, a builder may be enough. A custom build makes sense when speed, SEO, integrations or custom features matter to the business.

Do you redesign existing websites?

Yes. We can improve what's there or rebuild it, keeping your search rankings in mind with redirects and clean metadata.

What technology do you use?

Mostly Next.js and React on the front end, with Node or Laravel behind it, chosen to fit the project.
