I'm sure this will surprise no one--San Jose is the top city in the US for web developers. A Zippia study looked at web developer salaries, available jobs, and cost of living to determine the best spot for a job. Despite our astronomical cost of living, San Jose still came in first with 2,930 available jobs, an average entry-level salary of $63,320 (#1), and an average salary of $107,500 (#1).
The runner up was Seattle followed by Framingham (?), Austin, and San Francisco.
