Recent projects include the University of Toronto Scarborough's Human Geography department and Link21, a regional rail planning initiative. Kalamuna also runs an admissions diagnostic for colleges that want to fix where prospective students drop off.

The company has publicly endorsed the UN Open Source Principles, which tells you something about how it thinks about the tools it builds with.

Today State Creative builds custom sites on WordPress, Drupal, and Laravel for financial firms, professional services, and retailers. Ongoing WordPress maintenance and security work is a large part of the business.

A good fit for organizations that want the same team handling both the build and the years of upkeep that follow.

Frequently Asked Questions

How much does web development cost in San Francisco?

It depends on the build type. A template or CMS marketing site sits at the low end. Custom application work with a full engineering team costs far more. Bay Area rates run above the national average, so ask for a written scope before comparing quotes.

How long does a website project take?

Usually two to four months. Discovery and design often take as long as the code. Content is the most common delay. Sites that need custom integrations, migrations, or accessibility review run longer.

Who owns the code and the accounts after launch?

Ask before you sign. Some agencies hand over the repository, domain, and hosting logins. Others keep the site on a proprietary platform you cannot move. Ownership terms decide how easy it is to switch agencies later.

Do San Francisco web developers also handle SEO?

Sometimes, but not always. Many firms cover technical setup like site speed, structured data, and clean URLs. Ongoing search work is often a separate retainer. Confirm what is in scope so nothing falls between the two contracts.

What is the difference between a web design agency and a web development firm?

Design shapes it, development builds it. Design covers layout, brand, and user experience. Development covers code, databases, and integrations. Most Bay Area shops do both, though one side is usually stronger.

Is a local agency worth paying more for?

Often yes for complex work. In-person workshops help when many stakeholders are involved. For a straightforward marketing site, a remote team can do the same job. Ask whether engineering is in house or subcontracted.

What should I get before the project starts?

A scope document and a timeline. It should name deliverables, review rounds, and what counts as out of scope. Change requests are where budgets grow. Get the hourly rate for extra work in writing.

Types of Web Development Services in San Francisco

Custom Web Application Development. Software built for a specific business process, not a template. Common for startups, SaaS products, and internal tools. Usually the most expensive category of work.

CMS Website Development. Sites built on WordPress or Drupal so staff can edit pages without a developer. The default choice for nonprofits, universities, and professional services.

E-Commerce Development. Shopify, WooCommerce, and custom storefronts with payment and inventory integration. Product data and shipping rules drive most of the cost.

Front-End and UX Work. Interface build, design systems, and accessibility remediation. Matters most for sites with a lot of traffic or a required compliance standard.

API and Systems Integration. Connecting a site to a CRM, ERP, payment processor, or donor database. This is where fixed-price quotes usually break down.

Mobile and Cross-Platform Apps. iOS and Android builds, often paired with a web back end. Several Bay Area firms handle both under one contract.

Maintenance and Support Retainers. Security patches, plugin updates, backups, and small changes after launch. Priced monthly and easy to overlook during procurement.

Staff Augmentation. Hiring vetted engineers into your own team instead of outsourcing a project. Useful when you have a product manager but no engineers.

How to Choose a Web Development Company in San Francisco

Match the firm to your project size. A studio that builds nonprofit sites is not the right fit for a payments platform. The reverse is also true, and it gets expensive.

Ask who writes the code. Some agencies subcontract development overseas. That is not automatically bad, but it changes communication and time zones. Get an answer before you sign.

Check the platform, not just the portfolio. A beautiful site you cannot edit becomes a liability by year two. Ask which CMS they recommend and why.

Get post-launch terms in writing. Support hours, response times, and who holds the hosting account all belong in the contract. Verbal promises fade after handoff.

Talk to two references with similar projects. Ask about budget changes, missed dates, and how the team handled problems. Logo walls tell you very little on their own.
