Codex + InstaCloud

Codex is OpenAI's open-source coding CLI. It runs locally with sandboxed file and shell access, and ships bindings for VS Code, Cursor, and Windsurf so you can drop into the same agent from any editor. Run `npx -y insta setup agent` once and the insta CLI plus the InstaCloud agent skill are installed for every coding agent on your machine — any OS, any shell. From the first prompt it knows how to create projects, add postgres, storage, and compute, pull secrets into .env, branch a full environment per feature, and deploy.

    One prompt installs the insta CLI, MCP, and agent skill, and creates your project.

  3. 3

    Develop your project

    Ask Codex to build and deploy an app on InstaCloud

    prompt

    Build a todo app with Postgres for the data, then deploy it on InstaCloud and send me the live URL

Example Prompts

  • Ship this repo and send me the live URL

  • This app needs a database, set one up and connect it

  • The deploy just failed, figure out why and fix it

  • Upgrade the app to 2 vCPUs before tomorrow's launch

  • Branch the whole environment so I can try this migration safely

  • Run three agents on this project without them stepping on each other

  • Promote the preview branch to main

  • Pull the project secrets into .env so I can run it locally
