Comparison of the main development agents assisted by IA, their modes of integration and the uses to which everyone best responds.
In 2026, AI-assisted development was structured around two distinct approaches, which this overview compares. On the one hand, agents controlled from the terminal, designed to take care of long and multi-step tasks that are delegated before reviewing the result. On the other hand, development environments natively designed for AI, where assistance is integrated into each level of the editor, with agent sessions conducted in parallel and a shared context.
The comparison covers Devin, Windsurf, Cursor and Warp, focusing less on raw performance scores and more on the ways each tool works. The decisive criterion has shifted to the suitability for a given task, the cost of switching from one tool to another and the degree of control left to the developer.
On the economic front, the period is marked by strong pressure on prices, which makes the execution of coding agents accessible at much lower costs than those charged a year earlier, including via open-weight models.
