This blog highlights the 21 best AI coding tools in 2025, including AI assistants, IDEs, and more.

AI coding (or vibe coding as many call it today) remains an important aspect of software development in 2025. Gartner suggests that 80% of app activity will use no-code in 2025, up from 25% in 2020. The rise is worth noting, and it makes sense to act on it. Modern AI assistants can autocomplete code snippets, generate entire functions, translate code between languages, find and fix bugs, write documentation, and much more. Here's a detailed look at 21 of the best AI coding tools in 2025.
