The stack
“React made it easier to structure the interface and connect it to the live simulation state, while keeping the project maintainable as more systems were added.” — the maker, Sep 2026 ↗
“Supabase provided a simple way to add real-time presence without building and maintaining a separate backend, which was ideal for a mostly static web project.” — the maker, Jul 2026 ↗
“I chose Codex for its strong repository awareness and its ability to investigate bugs, modify code, run checks, and prepare focused pull requests.” — the maker, Sep 2026 ↗
“What mattered most was its ability to inspect the repository, run commands, follow dependencies across multiple files, and handle larger coding tasks from the terminal.” — the maker, Jul 2026 ↗
“The main reason was having AI assistance directly inside the editor, with enough project context to make useful changes without constantly copying files into a chat.” — the maker, Jul 2026 ↗
