How Much Does Web App Development Cost in 2026?

A web application usually costs between $5,000 and $30,000 for a first release, depending on features, users and integrations. A focused MVP, portal or internal tool often lands between $8,000 and $30,000. Smaller pieces, such as a single integration or automation, can cost a few hundred to a few thousand dollars.

Web app costs at a glance

Project	Typical starting price	Typical timeline
Code audit of an existing or AI-built app	$390	5 business days
Single integration (e.g. form to CRM, Stripe checkout)	From $590	About 1 week
Two-way sync between systems	From $1,490	2 to 4 weeks
Production hardening of an AI-built prototype	From $1,490	2 to 4 weeks
Custom platform with user accounts	From $4,990	6 to 12 weeks
Web application MVP, portal or internal tool	From $5,990 (most $8,000 to $30,000)	8 to 14 weeks

What the research says: For context, the median pay for software developers in the US was $64.44 an hour in May 2025, before benefits and overheads. Hiring an in-house developer is a long-term cost, while a project team is paid for the work. (Source: US Bureau of Labor Statistics.)

What drives the cost of a web app?

1. Number of features. Each screen, workflow and rule adds design, build and testing time.
2. User roles and permissions. Admins, staff and customers seeing different things adds complexity and security work.
3. Integrations. Payments, CRMs, ERPs and email platforms each need building and testing.
4. Data and reporting. Dashboards, exports and complex calculations take time to get right.
5. Design. A custom interface costs more than a standard admin layout, but is easier for customers to use.
6. Quality and security. Testing, access control and monitoring are essential for anything handling customer data.

Build vs buy: when custom software is worth it

Before building, check whether existing software does 80% of what you need. Custom software makes sense when your process is a competitive advantage, off-the-shelf tools force costly workarounds, or you need to connect systems in a specific way. Our guide to build vs buy walks through the decision.

How to keep a web app budget under control

1. Define the smallest first release that solves the core problem.
2. List must-have features separately from nice-to-haves.
3. Agree user roles and permissions early.
4. Plan integrations up front, with access to each system’s API documentation.
5. Budget for hosting, monitoring and ongoing improvements after launch.

From our projects: Many founders now arrive with an app built in an AI tool. We start with a $390 code audit to find security and stability issues before deciding whether to harden it or rebuild. See AI prototype to production.
