Vibe coding and the growth of AI-powered coding platforms gave rise to yet another battleground among tech companies. 

In December, Google released Jules, an autonomous coding agent that can fix bugs asynchronously, as an experiment. However, during Google I/O, Google announced that Jules will now be available in beta. 

With the broader release of Jules, Google positions itself as a strong competitor against a rising number of AI coding assistants designed to write, check and fix code autonomously. 

Josh Woodward, vice president of Google Labs, told reporters in a briefing that Jules “will be available to help developers fix bugs, create tests, consult documentation all happening in the background.”

“People are describing apps into existence,” Woodward said. “This started out as an asynchronous coding agent with the idea that, what if you created a way where you could assign tasks to this agent for the things you didn’t want to do?”

Jules will be integrated into GitHub and uses Google’s Gemini 2.5 Pro. During the public beta phase, developers can access Jules for free but with usage limits. 

Asynchronous and parallel

Jules works asynchronously, allowing developers to assign it a task while they work separately on something else. It runs tasks inside a virtual mac...
