Coding & data courses compared
Online coding, data science, DevOps and interview prep courses and bootcamps we've reviewed, compared on price and refunds.
This page is for people learning to code or work with data online, whether they're curious beginners, career changers aiming for a first tech job, or developers preparing for interviews or picking up DevOps and cloud skills. It covers low-cost subscription sites alongside full bootcamps with mentors. If you only want to try coding for a weekend, free courses and tutorials are a fine place to start before paying for anything.
Decide how you learn best. Some sites teach in the browser with short exercises, some use video, and some give you text lessons and real projects. Bootcamps add mentors, deadlines and career help, but cost thousands of dollars, and their job guarantees come with strict conditions. Check what the subscription includes, how renewals work, and the refund window, because several sites say fees are non-refundable.
Prices we saw ran from free tiers and about $14 a month to $99 to $299 a year for all-access memberships, and about $4,900 to $13,900 for bootcamps.
