The Stack Overflow Developer Survey is the largest annual study of the global developer community โ€” 49,000+ responses across 177 countries in 2025, its fifteenth year. JavaScript leads for the 13th year running, but Python surged +7 points โ€” the largest single-year jump โ€” cementing its dominance in AI, data science, and back-end development. The AI story sharpened further: 84% of developers now use or plan to use AI tools (up from 76% in 2024), with 47% using them daily. ChatGPT and GitHub Copilot remain market leaders, but Claude Code and Google Gemini have broken into the top tier. Below: language popularity, framework usage, salary by role, work environment, and the AI tooling shift.
