Web Design Agencies in Los Angeles, California: Marketing Sites, Web Applications, and Six Firms to Compare

Published Read 7 min read

Contents: 6 sections

The Los Angeles addresses in this group run from Flower and Figueroa streets downtown to Center Drive, Camden Avenue, and West Washington Boulevard. Three of the six firms also list offices outside the city: Black Flag Creative in Irvine and Sacramento, Bop Design in San Diego and Orange County, and CodeVix in Bulgaria and North Macedonia. Between them, the firms describe B2B marketing, digital marketing, interface design, and custom web application development, which makes the first question for a Los Angeles buyer a practical one: are you building a website, a piece of software, or both?

Marketing Site or Web Application: Scoping a Los Angeles Project

Which one are you building?

A marketing site explains and persuades. Its pages describe what you offer, answer questions, and ask the visitor to call, buy, or get in touch, and your own staff may edit it through a content management system. A web application is software that people use: they sign in, enter or look up information, and complete tasks, such as booking, ordering, tracking, or managing an account.

Some projects need both. A company with a customer portal still needs public pages that explain the product, and a marketing site can grow features, such as a quote calculator or a members’ area, that behave like an application. Before you speak to firms, write down what a signed-in user should be able to do, if anything. That list helps a firm judge what kind of team your project needs, which a page count alone does not show.

Among the Los Angeles firms here, CodeVix describes itself as a “Los Angeles-based web development company building custom websites, web applications & AI solutions,” and Black Flag Creative lists web development and UI/UX design alongside custom websites.

Interface design and design systems

When a project includes application screens, the design work goes beyond page layouts. Black Flag Creative lists UI/UX design and design systems among its services and says an engagement “may include strategy, information architecture, UX and UI design, prototyping, design systems, custom development, integrations, testing, and launch support.”

If a firm proposes a design system for your project, ask what it will contain, such as reusable components, type and color rules, and written guidance on how each piece is used, and in which tool you will receive it. Ask how designs will be handed to the developers, whether you will see clickable prototypes before development starts, and whether the designers stay involved while the screens are being built.

Phones, browsers, and app stores

Ask early where people will use what you are building. A responsive website adjusts its layout to the screen it is viewed on, and Black Flag Creative lists responsive web design among its services. A web application runs in a browser, on a computer or a phone. An app that people install from an app store is a separate piece of work, released through the stores rather than through your website. If a firm suggests building for more than one of these, ask which parts of the work would be shared between them and which would be built more than once.

Custom code: what you receive and who looks after it

Ask where the source code will be stored and whether the repository will be in your organization’s name, and what documentation and tests you will receive with it. Ask which outside services the application will depend on, such as payment, email, mapping, or hosting providers, and whether those accounts will be opened in your name.

If a firm offers AI features, as CodeVix does, ask which outside service runs them, what information from your users would be sent to it, and how its running costs would be billed.

Plan a first release

Keeping the first version small can make an application easier to price and to test. Ask each firm to separate what must work on launch day from what can follow in a second phase, and to price the phases separately. Then ask how the firm would decide what moves into the second phase if time or budget runs short.

Testing and launch

Black Flag Creative’s description of an engagement ends with testing and launch support, and both belong in the written agreement. Ask which browsers and devices the firm will test on, whether testing includes accessibility checks, and how you will report problems you find during your own review. Then ask what happens after launch: for how long the firm will fix problems in its own work without an extra charge, and how later requests for changes will be scoped and priced.

The marketing site around an application

A web application still needs public pages, and several Los Angeles firms on this page describe marketing work alongside web design. Bop Design calls itself “a B2B marketing agency with a knowledgeable team of design, branding, and marketing experts,” Coalition Technologies lists website design with SEO, PPC, social media, and email marketing, and SPINX Digital lists website design, web development, and digital marketing. NEWMEDIA describes itself as a Los Angeles web design agency. If your application and your marketing site will be built by different firms, ask each one how the two will share a design, and which firm will own the pages where the two meet, such as sign-up and log-in.

How Firms Are Listed

Firms appear in alphabetical order, which is not a ranking. A firm is included when its own website gives a Los Angeles address and lists website design or web development among its services, and when that website could be opened for checking. The list does not cover every web design firm in Los Angeles. Addresses, phone numbers, and service descriptions come from each firm’s website and were checked in September 2026. Where a firm’s website gives no single Los Angeles phone number, the listing shows the email the firm publishes.
