I was in the same situation, and considered https://keygen.sh, but realized implementing one myself is probably faster than trying to integrate a third-party platform. So, I ended up creating my own system, quite simple, in Node.js + MongoDB, and then I can add whatever integrations I need (currently I only needed Paddle). - Source: Hacker News / 24 days ago

I run https://keygen.sh. I don't share revenue figures anymore, but it's very profitable these days. I'm still (mostly) solo on it (I currently have a couple firms/consultants helping me push a handful of projects forward right now), but I'm evaluating this year whether or not I want to continue going solo; lots of work to do, and I can only do so much. - Source: Hacker News / 8 months ago

Long term HN user @ezekg also runs this https://keygen.sh/ if that might suit your needs (i.e. If you want to separate out licensing logic from the payment logic). - Source: Hacker News / 11 months ago

Keygen | Front-end Engineer | Full- or part-time | Remote (US only) | https://keygen.sh Keygen is an open, source-available software licensing and distribution API built and run by myself. I'm a bit stretched thin in terms of front-end and support.

2. Next, we need to creat a valid JWT for GitHub OAuth. The values used here are expected by GitHub including the profile image, access token (this is fake but in a similar structure), user email and name (in the spread ...user) and the sub which is the mock GitHub id. For more information on GitHub OAuth, check out the docs. - Source: dev.to / 10 months ago

Select GitHub from the available Sources and select the default connect option Connect using OAuth. You can find more details on GitHub OAuth here. - Source: dev.to / about 1 year ago

Create a new GitHub application for authentication and generate a Client ID and Client Secret by following this documentation. - Source: dev.to / over 1 year ago

The first thing that we need to do is to read Github's documentation and find the endpoint we need to make a request to. Per the documentation, we find out that the endpoint is a POST request to https://github.com/login/oauth/access_token. We also find out that the post request takes in 3 input parameters. client_id,client_secret and code. All of which we got from my previous tutorial. - Source: dev.to / almost 2 years ago
