I would be willing to support a free and open-source Hardcover because in that case, even if the platform failed, the code itself wouldn't simply vanish. Others could learn from it, build upon it, or even fork it. My investment would then contribute to a lasting, tangible resource. Furthermore, freeing and opening the source code would foster a community around the platform, increasing transparency and potentially leading to valuable contributions. It aligns with the open knowledge ideals many of us appreciate.
I will definitely not put money into yet another non-free and closed source platform; effort, maybe. Money, never.

Is there any updates on this ? I am curious to know how far have you got 😊

I am so pumped for this!

We have a dozen or so things to complete before this is done. Making progress!

Yay! Excited to have the opportunity to contribute (assuming I’m decent at React by the time it’s open sourced)!

Please Open source it all. API and all. The rationale behind this is I’m interested in making an epub reader and would love for it to automatically update my progress. Also while the website is great the iOS app needs work. It’s slow when moving from one screen to another sometimes asks for re-authentication when logging in it will notify that it’s already logged in I can tell this is NOT a native app possible react native or some such

We absolutely want to do this before the end of 2024!

This is one we're heavily considering. We might end up open sourcing only the front-end but keeping the API private. One of the difficult parts is the data to work with it locally. We think that could work by having a staging API that people work with locally that has removed all private information (private notes, non-publicly saved books).

We'd very much like to make this public and allow people to submit pull requests. If anyone would be interested in being an early beta tester of this let us know. When/if we do this we'd like to do it right, and that means having a great initial experience.
