Renue Co., Ltd. Releases "Code Damon," an Interactive UI to Use Claude Code from a Browser
Renue Co., Ltd. has released "Code Damon," an interactive UI that allows users to access Anthropic's AI coding agent "Claude Code" directly from their browser. This aims to democratize AI coding by making it more accessible to both engineers and non-engineers, overcoming the barriers of CLI-based tools through a user-friendly interface with character avatars and voice input/output.

Renue Co., Ltd. (Headquarters: Tokyo, Representative Director: Yusuke Yamamoto, hereinafter "renue") announced on GitHub in April 2026 the release of "Code Damon," an interactive UI that enables the use of Anthropic's AI coding agent "Claude Code" from a browser.
While Claude Code has become popular as a CLI-based tool, the workflow constrained by terminal operations has hindered its integration into daily work and its expansion to non-engineers. This product re-designs Claude Code as an interactive browser experience, adding character avatars and voice input/output to make collaboration with AI more approachable.
## 01 Overview of Code Damon
Code Damon is an interactive UI that allows users to utilize Claude Code from a browser. It was released on GitHub in April 2026.
Claude Code is a CLI tool used from the terminal, but this product enables its use in a browser. Users can complete code consultations, generation, and modification directly on their familiar browser screen. Functionally, it is exactly the same as Claude Code, using Claude Code directly as its engine without its own AI model or intermediate server. This product's role is solely to refresh the UI.
It features Zundamon, the official character of the Tohoku Zunko and Zundamon Project, as an avatar. The AI's response status is conveyed through the character's expressions, creating a more engaging conversational experience.
It also supports voice input and output, allowing users to speak and consult without stopping their hands, and listen to responses read aloud. Parallel work, such as coding while reading documents, is possible.
It can be used free of charge by both individuals and corporations. Users can obtain the source code from GitHub and start using it in a short time. It is easy for members unfamiliar with terminal operations to handle, promoting AI utilization across the entire team.
## 02 Background and Purpose of Development
Anthropic's Claude Code has rapidly gained popularity as an AI coding agent. It consistently supports code generation, refactoring, and test creation, boosting development productivity. However, using Claude Code requires terminal operations. While a command-line input style is efficient for those accustomed to it, it creates a psychological barrier for those unfamiliar.
The main window used for daily work is the browser. Most of a day's tasks, such as email, Slack, documents, and design tools, are performed in the browser. The situation where only Claude Code exists in an external terminal is not a natural workflow. Seconds of friction caused by switching windows accumulate, hindering the formation of a culture where AI is used regularly.
When expanding AI utilization to the entire team, this unnatural workflow impedes adoption. It makes it difficult for non-engineer members to interact casually, entrenching a structure where only a few heavy users benefit.
renue defined this situation as the "last mile problem in transitioning AI from a tool to a partner." The purpose of this product is to elevate the use of Claude Code into an "everyday browser-based experience."
In addition to browser integration, interactivity has been enhanced with two elements: characters and voice. Conversations with AI become closer to interacting with a partner rather than mere command responses. Claude Code is a groundbreaking product that allows even non-engineers to develop applications, and in Japan, where the IT talent shortage is severe, it is expected to handle many administrative and PC tasks. However, it has primarily been offered through engineer-oriented interfaces like Terminal and PowerShell, and although desktop apps exist, it remains a solution with high barriers to entry for non-engineers.
By incorporating Zundamon's image and voice into the UI, it provides an experience where users can easily talk to a cutting-edge AI agent and ask for app creation or administrative tasks.
In the short term, it aims to improve usability for individual developers, and in the medium term, to boost overall team AI utilization. It also presents a new value axis: the fun of the development experience.
## 03 Traditional Challenges
Disruption of Workflow by CLI
For users who conduct most of their daily work in a browser, the effort required to switch to the terminal every time they consult AI reduces usage frequency. For developers juggling multiple projects, constantly switching between the terminal and browser leads to accumulated context-switching costs. The moment an idea strikes, AI
