OpenAI Codex
OpenAI Codex is included as part of your ChatGPT subscription and does not require a separate purchase. It is available across multiple plan levels, each with different usage limits.
ChatGPT Plus costs $20 per month and includes Codex with usage limits that allow about 30 to 150 local messages or 5 to 40 cloud tasks every 5 hours. This plan is best for developers working on a few focused coding sessions each week.
ChatGPT Pro costs $200 per month and provides significantly higher limits, allowing about 300 to 1,500 local messages or 50 to 400 cloud tasks every 5 hours. This plan suits developers who need Codex throughout their full workday across multiple projects.
Business, Education, and Enterprise plans include the same per-seat limits as Plus. However, plans with flexible pricing can purchase additional credits to go beyond included limits. For automatic pull request reviews on all repositories, flexible pricing is required.
Roo Code
Roo Code follows a flexible pricing approach that puts you in control of costs. The extension itself is completely free and open-source. You never pay subscription fees to use Roo Code.
The Cloud Free plan costs nothing and includes token usage tracking, the ability to follow tasks from anywhere, task sharing with others, early access to free AI models, and community support through Discord and Reddit.
For advanced users, Pro costs $20 per month plus $5 per hour for cloud tasks. This adds cloud agents like PR Reviewer, remote task control called Roomote Control, and paid support.
Team plans cost $99 monthly plus $5 per hour for cloud tasks. This includes unlimited team members with no per-seat charges, shared settings and rules, and centralized billing for the whole team.
You only pay for the AI API calls you make to providers like OpenAI or Claude based on their pricing.
