# Fastest Programming websites

Canonical source: https://thefastestweb.site/fastest/programming

Publisher: TheFastestWeb

Programming resources, coding products and language-focused websites.

Public examples and embedded editors can affect loading; inspect blocking time as well as the overall score.

Scores are recorded Google PageSpeed Insights and Lighthouse lab measurements, not real-user Core Web Vitals certification. Compare the measured URL, device and test date. Historical scores do not establish current speed. Missing measurements are not zero. Total blocking time is not field interaction to next paint. Paid plans and sponsorship do not increase measured scores or organic leaderboard rank.
