Languages & Frameworks tools

The long trends kept going in the last year, and the 2025 Stack Overflow developer survey put numbers on them. Python rose from 51% to 58% of respondents, TypeScript from 39% to 44%, Go from 13.6% to 16.5% and Rust from 12.7% to 14.9%. On the JavaScript side, React stayed the most used frontend framework and Next.js kept growing, while Bun, the runtime that competes with Node.js, grew its monthly npm downloads nearly eightfold. Tailwind CSS has become close to a default in the stacks listed here.

This list is ranked by how many Stackness members keep each language or framework in their stack. Because members list what they use rather than what they admire, it leans towards working stacks: a web app is usually TypeScript, React or Next.js and Tailwind CSS, and an API is often Python with FastAPI or Django, or Go. The top ten carry a twelve-week trend, the risers and fallers cover the last 30 days, and the history charts add npm downloads, survey shares and Stack Overflow question counts with their sources linked. The comparisons at the bottom, such as Go vs Rust and Bun vs Node.js, answer the most common which-one questions side by side.
