Web application development services, websites included
You have a product people use every week, or an internal tool your team lives in. A Lead and a Senior with AI agents build it for USD 16,000–17,600 a month, and you meet them before you commit.

What does web application development mean?
Web application development builds software that runs in the browser and behind a login: accounts, roles, data, workflows and the server that holds them, as opposed to a brochure website. Our small senior team designs the screens, writes the backend and the frontend, and ships through a gated release pipeline, in your repositories.
The screens are designed and checked at 1440 and 390 pixels, with automated accessibility checks on the critical flows.
What a web application costs, and what moves the price
Start from the sheet above: a Lead and a Senior for one month, 160 hours each, are USD 16,000–17,600. That is a new web application with two people. It is an example, not a quote, and the number moves with how many people the product needs and for how long.
Two people are enough when we have access from day one: the repositories, the environments, CI/CD, the cloud and one decision-maker. An application that already exists takes three or four, because someone has to learn the code first: a Lead and three Seniors are USD 30,400–33,600 a month. Behind change boards and tickets it takes more, with a timeline we state up front.

What you get from a web application build
- A web application on mainstream stacks: our published products use TypeScript with Next.js and React on Postgres, or a server-rendered modular monolith.
- Accounts and sign-in where the product needs them, with roles that decide what each kind of user can do.
- Screens designed in Figma and approved before they are built, then checked with axe in light, dark, forced colours and zoom.
- Tests in your CI, and releases where production runs exactly the build that was tested, with data migrations done before the new version takes traffic.
- All code and intellectual property are yours from day 1, and we sign an NDA before the call if you ask.
Websites, as a section of web application work
A marketing website is a smaller job of the same kind. As an example, one Senior developer for a 160-hour month plus a Senior designer for 40 hours is USD 9,000–10,000. Designers are priced on the same seniority table as engineers.
Our proof for websites is partial: two public sites, nine pages on a Cloudflare Worker and a public site built in three days. We publish no search, traffic or conversion results for any site.

What we have shown, and what we have not
Every claim is on its case page with its dates. Strong means built end to end with figures; Partial means a smaller or weaker proof, stated as such.
GovTech & enterprise coordination. Read the case
Strong A web portal on Next.js 16, React 19 and Postgres 18: 12 business areas, 43 screens designed at 1440 and 390 pixels, and every release a signed build.
Not shown: No usage figures are published.
Partial Its public site: 9 pages on a Cloudflare Worker.
Not shown: No search or traffic results.
AI marketing / MarTech. Read the case

Not shown: No uptime, user or revenue figures are published.
Housing & credit / PropTech. Read the case
Strong A server-rendered TypeScript web product: the public site, a family portal and staff consoles, with about 290 approved frames.
Not shown: We make no claim about launch, users or revenue.
Partial A public site live in 3 days, with every push live in under 90 seconds.
Not shown: Not presented as an indexed site. No search results are published.
Work we have not shown. Not in our published case studies: e-commerce stores and modernization of legacy applications. For those, ask us before assuming.
The rates behind every example
Engineers and designers are priced on the same seniority table, per hour worked. Add or remove people as the work changes; the arithmetic stays the same.

Frequently asked questions
What does web application development mean?
Building software that runs in the browser and behind a login, with accounts, roles, data and workflows, instead of a brochure website. We build the screens, the backend and the release pipeline, in your repositories.
How much does it cost to develop a web application?
A Lead and a Senior for a 160-hour month cost USD 16,000–17,600 at the published hourly rates. That is an example, not a quote. If the scope is open, Discovery (USD 7,000) comes first and ends with a backlog you can price.
How much does it cost to hire a web developer?
A Senior is USD 45–50 an hour, so 160 hours is USD 7,200–8,000 a month. A Mid is USD 35–40 and a Lead or Architect USD 55–60. They work in English or Spanish, in your tools, and you interview them before they start.
How much does a website cost?
As an example, one Senior developer for a 160-hour month plus a Senior designer for 40 hours is USD 9,000–10,000, at the published rates. It is an example, not a quote or a fixed price.
Do your web applications work on phones?
Yes, as responsive web applications: we design and check the screens at 390 pixels as well as 1440. That is not a native app.
Do you build native mobile apps?
Yes, as mobile app development: a senior team builds the app together with its web and backend, at the same rates. Our published mobile work is Autonomah's mobile app, and Discovery is where native or cross-platform is settled.
Can you work on a web application that already exists?
Yes. An existing application takes three or four people, because someone has to learn the code first: a Lead and three Seniors are USD 30,400–33,600 a month, as an example. Inside a company with change boards and tickets it takes more people and a timeline we state up front. We have no published case of modernizing a legacy application, so ask us before assuming.
Who owns the code?
You do, from day 1, together with the design files. We sign an NDA before the call if you ask.
What happens after delivery?
A change of the same size swaps a backlog item at no cost. New scope is quoted at the published rate before it is done. Defects found within 30 days of delivery are fixed at no cost.
