Limits and method

23

Limitations and open questions

Known constraints and missing evidence from the collected pages.

The collected pages do not mention any competitor products. Evidence gaps include lack of detailed security certifications, uptime status, and specific customer counts. Open questions remain about the exact limits of Codex usage on each plan and the full scope of plugin integrations.

24

Sources, method, and limitations

Evidence inventory, collection method, provider use, and constraints.

This report is based on 4 rendered pages from openai.com/codex, collected via browser rendering on 2026-10-18. The static provider was blocked, and external proof search was used to verify pricing. Limitations include incomplete coverage of the site (4 of 15 pages) and reliance on marketing pages for some claims.
