You could consider open source coding harnesses (I quite like Pi especially its customisability) as a middle ground and alternative.
And for what it's worth, Codex is still open source under Apache 2.0. Claude Code is closed-source.
Doesn’t matter if you’re using an open harness if the model is still cloud-based and closed!
