Google will shut down Jules, its experimental coding agent, on December 31, 2026, and fold what it learned from the tool into Antigravity, its agent-first development platform. Jules users have until November 11, 2026, to finish active sessions, after which the service turns read-only for the rest of the year. Google announced the move on October 29, 2026, the same day Antigravity gained a new Plugin Marketplace for one-click add-ons.
The shutdown timeline
The wind-down follows a fixed timetable rather than an immediate switch-off. Users can keep working in Jules until November 11, 2026, and Google has provided an export option to save settings, session history, and project data before it closes. After that date, Jules becomes read-only.
Code is not at risk in the move, because Jules worked with repositories hosted on GitHub, where branches and pull requests already live. The deadline is therefore about sessions and settings, not source code. Google has not given a time of day for either cutoff, so users who leave the move until the final evening could run out of time.
What Jules was built to do
Google launched Jules in December 2024 as an asynchronous coding agent, a tool that could take on software jobs without a developer watching every step. Developers connected a GitHub repository and assigned tasks such as fixing bugs, writing code, updating dependencies, and creating tests. Jules then worked in the background and returned its changes for review.
The idea was to clear the backlog of jobs developers say they do not want to do, from routine maintenance to small feature work. Google described Jules as an experiment in how asynchronous agents could help teams ship faster. That experiment now ends as a standalone product, even though its approach survives inside a larger platform.
Antigravity gets a plugin marketplace
Antigravity is Google’s agent-first coding environment, and the Plugin Marketplace is its new central directory for discovering and installing add-ons. Each plugin bundles up to five parts that install and update together: skills, model context protocol servers, rules, hooks, and custom agents. The aim is to replace manual setup across separate configuration files with a single install.
Launch partners cover software delivery, design, data, and security, including Atlassian, Canva, CrowdStrike, Databricks, Datadog, Dropbox, Figma, monday.com, Ping Identity, SentinelOne, Stripe, and Unity. Google also lists its own plugins for Docs, Sheets, Slides, Drive, Calendar, Firebase, and the Gemini API. The marketplace is rolling out in both the Antigravity app and its command-line interface.
Developers can browse the catalog from the Customizations panel in the Antigravity app or install a plugin from the terminal. The move fits Google’s push to open its tools to outside services, also visible in its connected apps platform for Search and Gemini. For teams, an agent can reach tickets, designs, logs, and payments without leaving the coding environment.
Why It Matters
The shutdown matters most to developers who built Jules into a daily routine, because the November 11 cutoff leaves less than two weeks to finish active work. Teams that used Jules for backlog tasks must plan the move to Antigravity, test whether its background execution covers old workflows, and confirm exports are complete well before December 31.
More broadly, the move shows Google consolidating its coding agents rather than running parallel products. Antigravity gains the marketplace as Jules closes, giving Google one place to grow agent tooling instead of two. That echoes Google’s decision to let rival agents into Android Studio, where openness and one strong platform matter more than owning every tool.
Background
Jules arrived when coding agents were still proving themselves, and Antigravity has since grown into Google’s main home for agent-led development. Google says it is working on bringing Jules-style background tasks into Antigravity, but it has not given a date for that feature, so former Jules users should plan around what Antigravity offers today.
