This is the final day of a week of Wave 10 updates, and it contains everything that isn’t Planning Mode or the Windsurf Browser.

On the enterprise side:

• Europe cluster: A datacenter in Frankfurt for our European enterprise customers that guarantees that all data processing and data retention stays within EU borders.
• Cascade in PCW: We have extended our percentage of code written (PCW) metric to also track suggestions accepted from Cascade.

And on the UX side:

• Browse past conversations without leaving the current one
• Refreshed visuals for Cascade’s code item citations and file pointers
• Interactivity with the Cascade terminal
• Cascade code-blocks match Windsurf theming
• Legacy chat mode removed from the Windsurf Editor

Cascade in PCW

Percentage of Code Written (PCW) is one of our most trusted metrics. It measures, at a character-level attribution, what fraction of the code that was committed to the codebase originally came from AI vs human. It accounts for edits and deletions in between suggestion acceptances and commits. The beauty of this metric is that it cannot be gamed. Providing fewer suggestions means a lower PCW. Providing worse suggestions that get edited or deleted means a lower PCW. Providing shorter suggestions to have more “absolute acceptances” often means a lower PCW. PCW is not a direct measure of productivity improvements, but is a directionally accurate proxy that our customers could trust.

Until this Wave, we were only measuring PCW for Tab suggestions (i.e. code coming from Tab vs not-Tab). In this Wave, our PCW metric also includes Cascade edits, giving a more holistic and representative view on the value driven by the overall Windsurf platform:

Europe Cluster

We want every enterprise to be able to use what we build, even given various rules and laws around security and compliance. That is why we made sure that our products are HIPAA compliant (for healthcare). Why we built the Hybrid deployment for secure data retention (for regulated industries in general). Why we put the work to receive FedRAMP High and IL5 authorization (for government and defense).

In this Wave, we are launching our Europe cluster, based in Frankfurt, Germany, for our European enterprise customers. It comes fully functional on day one with the Windsurf Editor and Plugins, with all data processing and retention happening within EU borders (and also using Germany-based third party model inference). This cluster may occasionally lag the core cluster based in the US when it comes to new feature availability, but we are dedicated to making this the best solution possible for our European customers. We already support over 100 large European enterprises, and look forward to expanding our support to the larger European market.

UX Improvements

Even as we introduce new cutting edge paradigms like Planning Mode and surfaces like the Browser, we always look for opportunities to improve the UX of our overall platform.

In this Wave, we made browsing past conversations much more easy and intuitive:

We also added added some visual polish throughout, such as file-type based icons for at-mentions and inline citations, and code blocks matching the overall Editor’s syntax highlighting to help with visual differentiation from the monocolor text:

When Cascade runs terminal commands, you can now interact with that inline terminal, which is especially helpful when executing the terminal command fully requires interactivity:

Finally, we’ve finally sunset Legacy mode in the Windsurf Editor, as everyone was (rightfully) using the agentic Write and Chat modes.

Concluding Thoughts

That’s a wrap on Wave 10! With extending flow awareness to planning and the browser, we are only continuing to expand the frontier of possibility with the overall Windsurf platform. And with a number of enterprise and UX features, we continue to strengthen the core offering.

Surf’s up!
