Top IT Service Providers for PHP in the USA

943 IT service providers ranked by rating, review volume and listing quality.

PHP remains one of the most widely deployed languages on the web, and a large share of the world's existing sites and applications run on it — including most WordPress, Drupal and Magento installations. Firms listing PHP are often maintaining and extending systems that already exist rather than starting new ones.

That makes the relevant question about the specific codebase rather than the language. Ask which framework and which version: a modern Laravel or Symfony application and a bespoke PHP system written a decade ago are different jobs requiring different people. For legacy work, ask what the upgrade path looks like and what it costs, because an unsupported PHP version is a security problem with a deadline.

Want your company here?

Between them, the 600 best-ranked of these 943 IT service providers cover web development (576), android (377), iOS app (353) and web design (350). They also list work in California, New York, Washington and Georgia. 597 of them have written a profile you can read before you get in touch.

We list more than 900 IT service providers in the USA listed for PHP development. The order comes from what each firm publishes and what has been verified about it, never from payment — at the top right now: Savas Labs, Square63 and Untold Studio.

Before you shortlist, check

Which framework they use, and whether it is a current, supported version
Code review and automated tests, not only manual checks
Hosting and upgrade plans for future PHP versions
That you own the code and can move it to another team

How is this ranking worked out?

The order comes from what each firm publishes and what has been verified about it, and never from payment:

Profile completeness: the details a buyer needs to judge a firm — what it does, who it serves, how it prices, who it has worked for
Earned trust: verification, awards and the other checks a firm has actually passed
Client reviews, where they exist: the rating is smoothed, so one five-star review cannot outrank a firm with a hundred good ones, and volume counts with diminishing returns

Client reviews are still rare across this catalogue, so on most lists today the order is set by the first two. A firm near the top is the best-documented and best-verified one we hold, which is not the same claim as the best one to hire. Use the list to build a shortlist, then check the firms yourself.

Sponsored listings are labelled and shown apart from this list. How rankings work

Only firms whose profile names the USA are counted here, so a firm that lists a town but no country is not yet included.

Where else can I look?

The same list elsewhere: UK (728) · India (669) · Germany (258) · Ukraine (191).

Other specialisms in the USA: e-commerce (1,539) · Android app development (1,530) · iOS app development (1,452) · UI/UX design (1,355) · JavaScript development (762).
