Google kills AI coding agent Jules as Antigravity gets a plugin marketplace

What this is about

On October 29, 2026, Google announced two things for its developer AI. First, Jules, an AI agent that handles coding tasks on its own in the background in the cloud, will be shut down on December 31. Second, Google Antigravity, the newer "agent-centric" development platform, is launching a plugin marketplace. According to the main source, Google's reason for the shutdown is to consolidate its work on AI coding agents in one product. Lessons from Jules are meant to flow into Antigravity and other projects.

Timeline and what Jules users should do

• Until November 11: Sessions continue as normal.
• From November 11: Jules is read-only (you can view, but not work).
• December 31: The service ends.

You can export settings, environment variables (configuration values passed to programs), scheduled tasks, connected repositories (places where code is stored), the "memory" and logs of past work to local folders. The export may contain secrets such as passwords; the team warns you not to share the folder or put it in repositories. Code, branches and pull requests stay on GitHub. According to the source, the time and time zone of the deadlines aren't stated, so you should act early.

According to The Verge, Google said the benefit of automatic background execution will be built into Antigravity. Whether Jules histories or settings will be carried over automatically isn't settled.

What Jules was

According to Crypto Briefing, Jules connected to GitHub repositories; the agent handled things like bug fixes and feature requests on its own in virtual machines in Google Cloud rather than on your own computer. There was a free tier of 15 tasks per day, with a maximum of 3 running at once. Jules launched in late 2024 as a Google Labs experiment, got a public beta in May 2025 and became generally available in August 2025. Google hasn't published user numbers for this short life, so it's unclear how many developers are affected. According to Crypto Briefing, no equivalent of the free tier has been announced for Antigravity. The source describes early reactions on social media as mixed, but not hostile.

Antigravity and the plugin marketplace

Antigravity was unveiled in November 2025 and reached version 2.0 at Google I/O 2026. It has evolved into a tool that coordinates multiple agents and supports things like desktop management and scheduled tasks. Background execution was seen as the missing piece.

The marketplace is a directory from which you can install Google and third-party plugins with a click, in the Antigravity app and the command-line version. A plugin can contain up to five building blocks: skills (task workflows), MCP servers (connections between the AI and external services), rules, hooks (processes that run automatically at certain points) and custom agents. Until now, you had to write per-repository configuration files by hand.

Named integrations include Google Calendar, Docs, Drive, Sheets and Slides, as well as Atlassian (Jira), Canva, Figma, Dropbox, monday.com, Stripe, Datadog, Databricks, CrowdStrike, SentinelOne and Unity. The rollout is gradual, so not everyone will see the marketplace right away. The announcement doesn't mention pricing or plans.

In practice, and a word of caution

The author of the main source recommends opening the plugin list under "Customizations" in Antigravity, installing just one plugin at first (for example Sheets) and testing with read-only tasks, such as having it summarize a spreadsheet without changing it. Before installing, you can also ask the AI to list which skills, MCP servers, hooks and agents a plugin brings along and which write or delete actions it allows. With company accounts, check your internal policies first.

In an opinion piece, How-To Geek concludes that Antigravity beats coding with Claude if you work like a project manager: use plan mode, review plans and steer agents in the Manager view. Without oversight, the agent falls into error loops.

Our take

The end of Jules fits a pattern: Google is consolidating its coding offerings under Antigravity. According to Tech Times, Gemini CLI was already shut down in June for Free, AI Pro and Ultra users and replaced by the closed-source Antigravity CLI, with a free limit of about 20 requests per day instead of 1,000. If you build on Google tools, you should expect short product cycles. Pricing, limits and whether all Jules features will carry over remain open questions.
