The site runs on Astro with Starlight and was built end-to-end using OpenCode wired through OpenRouter with DeepSeek V4 Pro, which the author frames as proof that a budget AI model stack can ship a complete project. Content is currently sparse, starting with a Content Creation category, with more planned, and the project is now soliciting community contributions via pull requests. ## Full article daily.dev links to this article rather than hosting it.
