Google’s Jules Enters Developers’ Toolchains As AI Coding Agent Competition Heats Up
Google’s Jules enters developers’ toolchains as AI coding agent competition heats up, signaling a major shift in how coding tasks are managed. With a new command-line interface (CLI) and a public API, Jules is now designed to fit directly into developer environments, from terminals to CI/CD systems to everyday tools like Slack.

This move positions Google’s Jules as a more seamless assistant for developers, reducing context switching and making AI-driven coding part of daily workflows. As the race for AI coding dominance intensifies, Google is pushing Jules to stand out.
Jules Tools: Bringing AI Into The Developer Terminal
Until now, Jules was only accessible through its website and GitHub. That changes with Jules Tools, a CLI that lets developers run Jules directly inside their terminal. Instead of bouncing between web dashboards and GitHub repositories, coders can now delegate tasks to Jules in the same environment where they write and ship code.
“We want to reduce context switching for developers as much as possible,” explained Kathy Korevec, Director of Product at Google Labs.
Jules Vs. Gemini CLI: Two Different Approaches
Google already offers another AI coding tool, Gemini CLI, which also integrates into developer environments. Both tools rely on Google’s Gemini 2.5 Pro AI model, but they serve different needs.
-
Gemini CLI: Best for iterative collaboration, requiring back-and-forth with the developer.
-
Jules Tools: Built for tightly scoped tasks that can be executed independently once the user approves its plan.
Denise Kwan, Google’s senior developer advocate, explained in a Medium post that Jules was intentionally designed to be less interactive, running autonomously after task approval.
Why The Public API Matters
Beyond the CLI, Google has opened Jules’ API to the public. Previously, it was an internal-only resource. By making it available to developers, Google is encouraging deeper integrations into existing workflows. Developers can now embed Jules into their CI/CD pipelines, automation scripts, or even team collaboration tools where speed and efficiency are critical.
This change means Jules is no longer just a standalone coding agent — it’s becoming part of the toolchain muscle memory developers already rely on.
The Bigger Picture: AI Coding Agent Competition
With Jules entering developers’ toolchains, the AI coding agent space is getting more crowded and competitive. Microsoft’s GitHub Copilot, Anthropic’s Claude integrations, and startups building AI-first dev tools all want a slice of this emerging market.
Google’s strategy seems clear: embed AI coding deeply into developer habits before competitors do. By offering Jules in terminals, pipelines, and APIs, Google is betting that developers will embrace convenience and automation at scale.
