opencode and chat-ui share 8 technologies: MCP, @aws-sdk/credential-providers, Tailwind CSS, htmlparser2, Zod, satori, marked, and katex. Both are written in TypeScript.

- [anomalyco/opencode](https://seerepo.com/r/anomalyco/opencode): The open source coding agent.
- [huggingface/chat-ui](https://seerepo.com/r/huggingface/chat-ui): The open source codebase powering HuggingChat

- Size: Lines written by people and agents, without generated ones; code files, without tests.
- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
