Best AI agents for engineers

Working software engineers and tech leads.

Engineering is the category where AI agents have crossed the line from "interesting demo" to "would not give it up." The right pick depends on whether you want an in-editor copilot, an overnight autonomous agent, or an issue-to-PR pipeline running off GitHub.

This page is the shortlist we use day-to-day, with the trade-offs spelled out plainly.
