Tidewave Web: in-browser coding agent for Rails and Phoenix

Summary

Today, we’re introducing Tidewave Web for Rails and Phoenix: a coding agent that runs directly in the browser alongside your web application, in your own development environment, with full page and code context. Unlike traditional coding agents that require constant back-and-forth, Tidewave Web knows your UI state, understands your framework, and runs within your actual development environment. No more describing what’s on your screen, copying stacktraces, or losing context between tools. VIDEO Our key features are: Shared page context - Tidewave has direct access to your current UI state and automatically maps it to the corresponding controllers, views, and templates, eliminating the need to describe what you’re looking at or manually trace code paths Deep framework integration - Tidewave can execute code within your running Rails/Phoenix app, query your database, monitor logs, access documentation, and more, giving the agent the same developer tools that you have Collaborative browser testing - Tidewave builds complete features in your app and validates they work right there in the browser. Use our point and click inspector to suggest improvements and request changes Runs in your dev environment - Add one package to your Rails/Phoenix app, connect your existing GitHub Copilot or Anthropic account, and visit the /tidewave route from your web app in the browser You can try Tidewave Web for free. It’s all about the shared context Using traditional coding agents to build web features means constantly switching between tools. You see something in your browser that needs changing, switch to your editor to find the right template, then describe what you want to an AI that can’t see the web page. The agent says it’s finished. You refresh your browser and get a runtime exception. Back to the editor to explain the error. The agent fixes it. Back to the browser and now there’s a missing database migration. Back to the editor again. You become a constant translator for an age...
