OpenCode scores 12 points higher. OpenCode leads on maintenance and adoption and docs.
What this does not tell you
Scores are percentiles of public GitHub signals. Nobody here tested these tools hands-on, so the higher score is not a verdict on which suits your project. Yellow marks the higher value.
Which one fits you
From measured data and licences, not from testing.
Pick OpenCode if
- Recent activity and releases matter most to you (maintenance 76).
- You want the more widely adopted option (adoption 95).
- You want the higher README docs score (docs 22 vs 10).
- You want the tool whose automated scan found no issues.
Pick Codex if
- No measured signal where it leads all the others.

Why different labels?
A label partly reflects how much of each tool is visible and scannable, not only how risky it is. A tool without a lockfile cannot get a dependency check.
- OpenCode: no issues found
- Codex: 4 critical-severity known vulnerabilities in runtime dependencies (OSV)

Questions about OpenCode vs Codex
Answers use this week's StackGrade data.
OpenCode or Codex: which scores higher on StackGrade?
OpenCode scores 12 points higher in Week 45: OpenCode 70, Codex 58 out of 100. The score combines maintenance, adoption and docs (percentiles of public GitHub signals): OpenCode 76, 95 and 22; Codex 74, 74 and 10. Community (20% weight) is not measured yet. It is not a hands-on test, so a higher score does not say which tool suits your project.
Is OpenCode or Codex safer to use?
Safety labels from the automated scan of 2 Nov 2026: OpenCode: No issues found, no issues found in this week’s scan; Codex: Caution, 4 critical-severity known vulnerabilities in runtime dependencies (OSV). It is an automated scan, not a manual audit.
Which is more widely used, OpenCode or Codex?
By GitHub stars: OpenCode 223,907, Codex 132,785. Adoption score (percentile among all 52 tracked tools): OpenCode 95, Codex 74. Stars are one public signal and do not measure real-world use.
