Key Features	• Local Codex CLI coding agent that runs on the developer’s computer • Install options documented for Mac, Linux, Windows, npm, Homebrew, and GitHub release binaries • IDE path for VS Code, Cursor, and Windsurf plus a Codex Web path for cloud-based agent work	• AI-powered browser automation via natural language • Custom ChatBrowserUse LLMs (BU Mini / BU Max) • Skill APIs — turn any website into a REST endpoint

✓Official README confirms local CLI, IDE, desktop-style, and Codex Web workflow options
✓Fits teams already using ChatGPT plans or OpenAI APIs for engineering work
✓Strong candidate for testable, issue-sized tasks where CI and human review can catch mistakes

✗OpenAI homepage and pricing page were blocked by JavaScript/cookie challenge, so plan limits and prices require manual verification
✗Generated code still needs review, tests, and security checks before merge
✗Broad repository permissions or deployment access would be risky without admin controls and audit policy

✓Combines open-source experimentation with paid cloud infrastructure
✓Useful when a website has no API and an agent must click, type, extract, or submit forms
✓Pricing exposes concurrency, credits, and task limits clearly enough for prototype planning
✓Stealth/proxy features are differentiated versus plain Playwright scripts

✗Browser automation is inherently brittle when target sites change UI or block bots
✗Stealth and CAPTCHA features can raise compliance concerns depending on use case
✗Cloud pricing can rise quickly for long-running sessions or high task volume
✗No direct MCP support was confirmed from fetched pages, so integration may require API glue
