Web apps that do one job well
Every Devv project is one focused web application. It solves one clear problem for your customers or your team, and it works on desktop and phone.
Every app we build works on phones and can be added to the home screen, where it opens like an app. Native App Store and Google Play apps are planned for early 2027. We do not build games or live video platforms, and we will tell you on day one if your project needs one.

Your questions answered
Quick answers about building and launching with Devv.
What does fixed price mean at Devv?
Before any work starts, you get the scope, the launch date and the price in writing. The price does not change unless you ask for something outside that scope, and we quote any addition before we build it. There is no hourly billing.
How much does it cost and how long does it take?
Plans are $5,000, $10,000 or $15,000, and apps go live in 3 to 10 weeks depending on the plan. You pay 50% to start and 50% at launch.
What kinds of web apps do you build?
Booking systems, client portals, dashboards, internal tools, simple marketplaces and AI-powered apps. Each one is a focused web app that solves one clear problem and works on desktop and phone. We do not build games or live video platforms.
Who is Devv for?
Founders who want a working first version, small businesses replacing spreadsheets and paperwork, and teams who need an internal tool without a months-long wait.
How do you use AI to build?
We use AI-assisted tools for design, coding and testing, which is how we deliver in weeks. Every app is still tested by hand and reviewed by an independent developer before it goes live.
Do I own the code?
Yes. The code, the data and every account are in your name from launch day, so you are never locked in to Devv.
What does it cost to run each month?
Hosting and other services bill you directly. We give you a list of expected monthly costs before you sign.
What if I need changes after launch?
Bugs are fixed free during your plan's bug-fix period. New features are quoted separately or covered by a monthly plan.
Can you build a mobile app?
We build web apps that work on any phone and can be added to your home screen, where they open like an app. Your users need no download from a store, and updates reach them instantly. We do not publish to the App Store or Google Play yet. Native mobile apps are planned for early 2027; mention it in the form and we will contact you first.
What do you need from me?
One to three hours a week for feedback, plus your logo, text and images.
Will you keep my idea private?
Yes. We are happy to sign a confidentiality agreement before you share details.
What if my project is bigger than the Full plan?
Tell us anyway. We will say honestly if we can split it into phases or if another team would suit you better.
Ready to launch your web app?
Pick whichever is easiest. We reply within one working day.
