Tips and best practices
Web app vs desktop app
Web app vs desktop app
- Use the Codex web app for fast ideation: architecture questions, debugging help, API examples, and implementation plans when you are away from your local environment.
- Use the Codex desktop app when you need execution: reading and editing repo files, running terminal commands, applying patches, and validating changes in the actual project workspace.
Hackathon workflow
Hackathon workflow
- Start in the web app to shape the MVP scope, pick the stack, and outline milestones.
- Move to the desktop app to implement features end-to-end, run checks, and iterate on real code quickly.
Prompting tips

- Give concrete constraints: framework, target file paths, expected API behavior, and acceptance criteria.
- Ask for small, testable increments and request verification steps after each change to keep delivery reliable.
