What became possible in your product with Astra that was not practical before?

Building a modern entertainment app with complex integrations, native apps (iOS in progress), and optimizing it for discoverability, all on the side while raising kids would not have been possible before tools like Astra.

Hey Product Hunt! 👋

I'm Lennart, creator of mosaic.

Like many of you, I love keeping track of the books I read, the games I play, and the movies and shows I watch.

But my collection was scattered across Letterboxd, Goodreads, Trakt, Steam, GOG, and more. Each service knew about one part of what I love — but none of them saw the whole picture.

So I built mosaic to be one beautiful home for my entire media collection.

What makes mosaic different:

Cross-media library — You cann see everything you love together, rather than in separate apps.

Import your existing collection — Bring in data from services like Steam, GOG, Epic, Goodreads, Letterboxd, Trakt and more.

Discover what's next — Follow the creators you love — actors, directors, authors, game studios and more — and get notified when their upcoming work is released.

A personal discovery engine — Explore new movies, shows, games and books across all four media types, based on what you're interested in. Loved a book? mosaic might recommend the movie to it. Enjoyed a game? Discover the accompanying series or book.

I built mosaic because I wanted more than a collection of disconnected lists. I wanted one place to see what I've experienced, what I'm enjoying now, and what's coming next.

I'd love to hear what you think! Which creators would you follow first, and what would make mosaic part of your daily media routine?
