You can now manage and upload your own reaction library. Just go to the home page and open the Reactions tab.

You can upload reactions for personal use or publish them for everyone. To save space and bandwidth, only MP4/WebM videos are allowed - but if you have a GIF, you can convert it directly in your browser. The same applies to images: only WebP is supported, with built-in conversion available.

Each reaction can have up to 15 tags and a description to improve search. If you're publishing reactions for others, please use tools like Google Reverse Image Search to add as much context and relevant tags as possible so your content is easy to find.

One reason I built this “last feature” is because I've personally collected a lot of reactions and needed a better way to organize them. Reactions are a core part of internet culture, and having full control over them can be a real advantage. There's also the issue of Tenor potentially shutting down, and the alternatives are either uncertain or not great. Long-term, there's potential for heahy to offer an API and become one of those alternatives.

That said, the reactions feature is still raw and largely untested. I'm releasing it early so people can try it out. Over the next few days, I'll be fixing bugs, filling in missing features, and integrating it into heahy's posting flow. Depending on feedback, an API might follow.

You might also notice a “Tip” button - yes, that's intentional. Supporting content creators is part of the long-term plan, and reactions will likely be one of the first areas to get it. If you publish early, there's a chance it could pay off later.

Anyway, give it a try - upload your own reactions, save favorites, or publish something for everyone to use.
