Tools that sell code usually put a platform between you and the buyer, take a cut, and work only where Stripe does. RepoAccess is one Cloudflare Worker on your own account. A buyer pays with the provider you already use, types their GitHub username, and is invited to the team holding the repo. A refund or chargeback revokes it and cancels a pending invite. Core is AGPL with Stripe. Pro adds Paddle, Lemon Squeezy, Gumroad, Razorpay and Telegram Stars. No OAuth, no server, free Workers tier.
