Gerrit User Summit 2026: Code review in the agentic era

Posted on by

In two weeks, the Gerrit community is heading back to where it all started.

On 9–10 November, Gerrit User Summit 2026 will take place at Google’s campus in Sunnyvale, California. Gerrit Code Review was born at Google in Silicon Valley, and the last summit Google hosted was organised by Gerrit’s and JGit’s founder, Shawn Pearce, ten years ago.

The summit is free, open to anyone who registers, and hosted by Google in cooperation with GerritForge and the Gerrit community. Two days of talks, demos and conversations with the people who build, run and depend on Gerrit at scale, plus a morning of jj talks and a three-day hackathon hosted and organised by NVIDIA straight afterwards.

The full agenda is now live. Here’s what’s on each day, and why this year’s programme is one not to be missed.

Code review in the age of agents

AI coding agents are writing more code than ever. Someone – or something – still has to review it, validate it and ship it safely.

That question runs right through this year’s programme. Speakers from Google, NVIDIA, ACME Gating, GitLab and GerritForge are tackling how code review holds up when agents join the team: keeping agentic coding safe, managing load when automated traffic spikes, and scaling Git storage for workloads nobody planned for five years ago.

Alongside that, the summit keeps what the community values most: deep technical sessions from the maintainers themselves, real-world stories from teams running Gerrit in production, and plenty of time to talk to the people behind the code.

Day One – Nov 9: Core Architecture, Scaling, and Agentic Workflows

Day one is about Gerrit itself: what’s new, what’s next, and how the teams running it at scale keep it fast.

Luca Milanesio (GerritForge) opens with the latest highlights from the release, and later lays out how Gerrit and JGit are being rebuilt for AI-era storage. Monty Taylor – who helped launch OpenStack and designed the workflows that became Zuul and OpenDev – makes the case for keeping agentic coding safe with the human collaboration tools we already trust. In the afternoon, Hudson River Trading, NVIDIA and GitLab share what they’ve learned running Git and Gerrit under serious load.

  • 5:30 PM: Social and networking

Doors open at 8:45 AM for registration.

Day Two – Nov 10: jj mini-summit and the future of Git scalability

Day two opens with a morning of jj and version control talks, co-hosted with the Jujutsu community, before turning to scaling for the AI era.

Google engineers share how they’re bringing jj into everyday workflows, from a VS Code extension to an open-source commit cloud. Daniele Sassoli and Emily Shaffer show what it takes to add native jj support to Gerrit. After lunch, Zuul creator Jim Blair joins Luca Milanesio on AI development at scale, and Shane McIntosh from the University of Waterloo presents research on keeping Git fast under AI workloads.

The summit closes with an open Q&A with the maintainers – your chance to ask the people steering Gerrit’s future anything you like.

  • 9:45 AM: jj VS Code extension at Google – Kevin Liao, Google
  • 10:15 AM: Version control and code formatting – Danny Hooper, Google
  • 10:45 AM: Where does your metadata live? – Patrick Hiesel, Google
  • 11:30 AM: Bridging the gap: adding native jj support to a Git-based SCM – Daniele Sassoli, GerritForge, and Emily Shaffer, Google

  • 4:05 PM: How to stack changes like a pro – Jacek Centkowski, SoftwareMill
  • 4:20 PM: Q&A with the maintainers
  • 5:20 PM: Social and networking

Doors open at 9:00 AM.

Stay on for the NVIDIA hackathon, 11–13 November

Straight after the summit, NVIDIA is hosting three days of hacking at its Santa Clara offices. This year there’s one shared goal: making partial clones a practical replacement for Git LFS across the Git and Gerrit ecosystem.

If you develop Git or Gerrit, maintain Git infrastructure, or have run LFS or partial clones in production, your experience is wanted. Spots are limited – email gerrit-hackathon-2026@nvidia.com to reserve one.

Join us in Sunnyvale

Whether you run Gerrit for thousands of developers, contribute to the project, or are working out how code review fits into an AI-driven workflow, this is the room to be in. Seats are limited, so if you’re planning to travel, now’s the time to lock it in.
