ClankerBend lets you build Codex Desktop plugins without rebuilding or re-signing Codex Desktop itself. It uses CDP to provide a more stable API for tasks such as transcript navigation, chat annotation, attaching a file to the prompt window, opening the side panel, and so on. YouTube demo (or click on the screenshot):
ClankerBend is an independent OneWill project compatible with OpenAI Codex Desktop on macOS. It is not affiliated with or endorsed by OpenAI (unless... 🥺).
You'll need macOS with Codex Desktop and nodejs. Then just:
npx clankerbendThat starts Codex Desktop with the default ClankerBend profile and bundled apps:
- ClankerID: switch between Codex accounts.
- VimNav: Vim-style transcript navigation, number rails, role jumps, search, and a side panel.
- Sticky Notes: select transcript text, click Add note, and the generated note will (1) create a markdown file and (2) attach itself to the current Codex prompt. Inspired by @zats.
ClankerBend writes runtime state outside the package:
- macOS:
~/Library/Application Support/OneWill/ClankerBend
Override with ONEWILL_CLANKERBEND_STATE_DIR.
Managed Codex account profiles live under the same state directory. The primary
profile remains your normal CODEX_HOME or ~/.codex; managed profiles get
their own codex-home and Electron user-data directories. You can start a
saved profile directly with:
npx clankerbend --account workClankerBend binds to 127.0.0.1 on an OS-assigned ephemeral port. The launcher
prints the exact host URL and bearer token, for example
Host: http://127.0.0.1:49152 and Token: ....
/clankerbend/* endpoints require a bearer token by default. For local protocol
debugging, you can set ONEWILL_CLANKERBEND_DISABLE_AUTH=1. Hosted app pages
receive the same bearer token from their app URL fragment and from a
host-injected HTML bootstrap so URL rewriting does not break app auth.
