Code with Claude Goes Global: London Today, Tokyo in June

Anthropic's Code with Claude developer conference runs in London today, May 19, the first time the company has taken the event outside the United States. A second stop follows in Tokyo on June 10. Both cities also get Extended days the following morning, aimed specifically at independent developers and early-stage founders who want more time with Anthropic's applied AI team. For a company that has spent much of the past year focused on enterprise deployments, the expansion signals a deliberate effort to keep its developer community close as the Claude platform grows more complex.

The San Francisco edition ran on May 6 and covered a broad range of capability demonstrations, including the multiagent orchestration features now in Claude's managed agents stack and the new agent view in Claude Code. London and Tokyo are expected to cover largely the same ground, with sessions running across three parallel tracks. The agenda was designed to let attendees self-select by technical depth rather than sitting through content pitched at a different level.

Three Tracks, One Day

The three programming tracks are Research, Claude Platform, and Claude Code. The Research track gives developers direct access to Anthropic engineers and researchers building the underlying models, covering topics like how model behavior is shaped by Constitutional AI training and what the current capability limits are for complex multi-step reasoning tasks. The Claude Platform track focuses on production-grade deployment: how teams are running agents reliably, what failure modes look like in practice, and how the managed agents infrastructure handles long-horizon tasks. The Claude Code track is the most operational, covering how engineering organizations are running Claude Code at scale, including the recently added agent view for managing multiple sessions from a single CLI interface.

The 1:1 office hours format is the element attendees have consistently said they find most valuable. Rather than a generic Q&A at the end of a session, office hours are scheduled blocks where developers working on specific integration problems can sit down with the Anthropic engineer most relevant to their use case. That format does not scale easily, which is part of why the Extended days exist: they provide more of that unstructured time for the indie developers and founders who may not have an enterprise support channel.

Why London and Tokyo Now

The timing of the international expansion reflects where Claude's developer base has grown. Anthropic has not published country-level usage breakdowns, but the company's recent partnership announcements tell part of the story. The PwC alliance, which includes rolling out Claude Code to a global workforce of hundreds of thousands of professionals, has a significant UK component. SAP's integration work spans European enterprise customers. In Japan, where Anthropic has been building local partnerships, there is demand for developer education that works in a Japanese-language context, including Japanese-language documentation and support channels.

The event format also reflects a tension Anthropic has been navigating as Claude becomes a platform rather than a product. Developers building on Claude Code need different things from developers building agentic workflows on the API, who need different things from researchers evaluating the model's capabilities. A single conference day in San Francisco served all of those audiences reasonably well when the developer community was smaller and more homogeneous. Three cities and two Extended days is a structure that acknowledges the community has grown too large and varied for one event to hold.

What to Watch From the Sessions

Anthropic has not pre-announced specific capability reveals for London or Tokyo, but past Code with Claude events have often served as the first public demonstration of features that go into general availability in the weeks that follow. The San Francisco edition introduced the agent view for Claude Code and showed early footage of the Dreaming memory system before those features shipped publicly. Developers watching the London livestream today should pay attention to anything shown in a research preview context rather than as a finished product.

The Extended days are arguably the more interesting experiment. A separate day designed specifically for independent developers and early-stage founders is a different kind of investment than a corporate developer conference. It suggests Anthropic is tracking the indie developer community as a meaningful part of its ecosystem, not just a funnel toward enterprise contracts. Given how much of Claude Code's early adoption came from individual developers building tools for themselves before enterprises noticed, that attention makes strategic sense.

Recordings from all sessions will be available after each event. For developers in time zones where the livestream is inconvenient, the recording library from London will be accessible before the Tokyo event, making it possible to watch and prepare specific questions before the June office hours.
