Best Developer Reference Sites
Documentation and Q&A judged on how fast it answers the actual question
Every site here is judged on how quickly it gets a working developer from "I have a specific question" to a correct, current answer. Documentation accuracy is checked against the current stable release of whatever it documents, not an archived snapshot. Search and findability matter as much as the content itself, since a correct answer buried three clicks deep loses to a slightly thinner answer that surfaces immediately.

Leading the list
Rank 01Editor’s pick
MDN Web Docs
Mozilla · founded 2005
The single most trusted reference for how a browser actually behaves, maintained with a rigor most vendor documentation still does not match.
95.6/100 Top 49 score—No changeRank 02Editor’s pick
Stack Overflow
Stack Exchange · founded 2008
Traffic has genuinely dropped as AI coding assistants answer more first-pass questions directly, but the accumulated answer archive is still what those assistants were largely trained on.

GitHub
Microsoft · founded 2008
Became the de facto identity layer for software developers almost by accident — a portfolio, a resume and a collaboration tool that outgrew its original pull-request feature entirely.

Dev.to
Forem · developer blogging

Questions
About this ranking
Why does Stack Overflow rank second despite declining new-question traffic?
The accumulated archive of peer-reviewed answers still scores near the top on documentation accuracy and search, even as new-question volume declines.
Is a site’s traffic a factor in its score?
No — traffic is shown for context only. Accuracy, findability and ad density decide the ranking.
Why isn’t ChatGPT or an AI assistant on this list?
AI assistants are covered separately in the AI Tools category. This list is specifically browser-based reference sites.
How is "ad density" judged for a free reference site?
By measuring ads-per-scroll and interstitial frequency directly, not simply noting whether advertising is present at all.
