AI plugin runtime compatibility map
Catalog read · 1,169 plugins · 16 runtimes
Of the 1,169 packaged plugins in the HOL catalog, 1,023 declare at least one agent runtime and 526 (51.4% of those) declare two or more. The most common pair is Claude Code and Codex, declared together by 367 plugins.
Which runtimes share plugins
Read across a row. Each cell counts the plugins that declare both runtimes, and the percentage is the share of the row runtime’s plugins that also declare the column runtime. The map shows the 10 runtimes with at least 10 plugins.

How we counted
- We read every packaged plugin in the HOL catalog on . MCP servers and skills listed on their own are not included.
- A plugin counts for every runtime its listing declares. Spellings of the same runtime are merged, for example Gemini CLI and Antigravity CLI, or Kimi and Kimi Code.
- Generic labels such as MCP, agent skills and standalone name a format, not a runtime, so they are left out.
- 146 plugins declare no runtime. They count toward the catalog total and nowhere else.
- These are declarations, not install tests. A plugin that names a runtime may still need setup there, so check the listing before you install.
- The State of agent plugins report reads the catalog on its own date, so its runtime figures can differ from this page.
Questions about runtime compatibility
Which AI agent runtime has the most plugins?
Claude Code: 710 of the 1,169 packaged plugins in the HOL catalog declare it, followed by Codex with 552.
How many plugins work in both Claude Code and Codex?
367 plugins declare both, the most common pair in the catalog. That is 51.7% of the 710 plugins that declare Claude Code.
How many AI plugins support more than one runtime?
526 of the 1,023 plugins that declare a runtime declare two or more (51.4%). The other 497 declare one.
Does a declared runtime mean the plugin was tested there?
No. The counts come from what each listing declares. HOL does not install every plugin in every runtime it names, so check the listing and its manifest for the runtime you use before you install.
