Sponsor CodexStacks
CodexStacks is an independent directory of 244 OpenAI Codex plugins, skills and MCP connectors, refreshed every night from OpenAI's curated catalog and GitHub, plus a weekly email about what's new. If your tool works with Codex, these spots put it in front of developers while they're choosing what to install.
Straight talk: CodexStacks launched in October 2026. We don't have meaningful traffic or subscriber numbers yet, so we won't quote any. Launch prices are set low to match, and we'll share real numbers with sponsors as soon as we have them.
Newsletter sponsor
$49 per issue launch price
- One sponsor per issue, placed near the top of the weekly CodexStacks email
- Your logo or name, about 50 words of copy and one link
- Clearly labelled "Sponsor"
Featured listing
$79 per month launch price
- Your listing in the Featured spot at the top of the directory home page
- Labelled "Featured" everywhere it appears

Category-page sponsor
$29 per month per category launch price
- A sponsor block on one category page, for example Developer Tools or Productivity
- One sponsor per category at a time
- Clearly labelled "Sponsor"
The fine print
- Month to month, no long contracts. Newsletter slots are booked per issue.
- Paid placements never change our best lists, which follow a published rule, and never earn a "tested" label.
- We only sell placements to tools that work with Codex or help people who build with it, and we can say no.
- Independent directory, not affiliated with or endorsed by OpenAI.
