I've heard this claimed dozens of times. I wonder if anyone at Github can confirm this theory and maybe give insight into why they haven't just done this?
Github has a decade of positive reputation to deal out, I don't see Grok or OpenAI jumping in and competing with that.
Easy enough to run from another CI or automated system.
But, the wrangler CLI isn't that much of a step up. Biggest items are installing the CLI and having the CloudFlare API token available in a secure manner.
Otherwise I reckon they’d have cloned GitHub already; possibly with a “Mirror to CodexHub? Free usage reset”.
