Fix-labelled changes, file change frequency, ownership concentration and maintenance cadence, each computed from this repository's analyzed commit window. None of them is derived from stars, which is why they are allowed to disagree with the curve above.

Notes on openai/codex

How many stars does openai/codex have?
GitHub currently reports 124,128 stars for openai/codex. The chart itself is rebuilt from historical star data, which records star actions and not unstars, so it reads as an attention signal rather than a net star count.
What does recent star activity look like for codex?
gitdebt observed about 747 public star actions for openai/codex over the latest 90 days of archive coverage (about 618 in the latest 30). This is an approximate attention signal, not a net-star count, because unstars are not present. That's below its lifetime average activity pace, which is common for mature projects.
Is codex still active?
Public archive data shows about 618 star actions for openai/codex in the latest 30 days of coverage. For repository activity, use the commit heatmap, commit trend, and contributor charts on this page.
When was codex created?
openai/codex was created on April 13, 2025. The first public star activity observed for openai/codex is from Apr 2025.

Light and dark variants, alt text, and one provenance line. Provenance is text in your README, never baked into the image URL, so the chart stays cacheable.

Paste it into Claude Code, Cursor, Codex, or any coding agent with your checkout open. It carries the measured numbers, the exact snippets, and the rules — including replacing an existing star-history widget in place rather than stacking a second chart under it.
