Sync Your Watch History Across Every Streaming Platform

Ever finish a show on Netflix and think, "Wait, did I already watch this on Hulu?" Or start a movie on your TV, only to realize you're halfway through it on your laptop? In the age of fragmented streaming, our viewing history is trapped in a dozen different silos. Keeping track of what you've watched—and where—has become its own annoying chore.

What if you could break those silos open? What if your watch history was just your history, no matter which app you used? That's the idea behind CrossWatch.

What It Does

CrossWatch is an open-source tool that automatically syncs your watch history across multiple streaming platforms. Think of it as a personal Trakt.tv, but running locally on your machine. It quietly works in the background, noticing when you finish an episode or a movie on one service and updating a central, unified database. This database can then be used to inform other platforms or simply to give you a single, complete view of everything you've watched.

Why It's Cool

The clever part isn't just the idea—it's the approach. CrossWatch is designed to be privacy-first. Your viewing data stays on your device; it's not sent to a central server. This is a huge win for anyone wary of handing over yet another slice of their personal data.

Technically, it's a neat piece of work. It likely uses a combination of browser extensions, local API listeners, or even screen-scraping techniques (responsibly) to detect playback events. The project is built to be extensible, meaning developers can contribute "connectors" for new streaming services without having to rewrite the core sync engine. It turns a universal problem into a modular, solvable one.

For developers, it's a fascinating case study in local automation, cross-application communication, and building a user-centric tool that respects privacy by design.

How to Try It

Ready to unify your watch history? Here's how to get started:

1. Head over to the CrossWatch GitHub repository.
2. Check the README.md for the latest installation instructions. You'll likely need to clone the repo and follow the setup steps for your operating system.
3. The project may require you to set up browser extensions or configure local services for each streaming platform you use.
4. Run the application, let it do its initial sync, and enjoy a unified watch history.

Since it's an active open-source project, make sure to read the docs carefully for any current limitations or supported platforms.

Final Thoughts

CrossWatch tackles a modern, first-world problem with an elegant, developer-friendly solution. It's the kind of tool you build because you're tired of the problem yourself. While it might require a bit of tinkering to set up (as most powerful local tools do), the payoff—a seamless, private, unified viewing history—is pretty compelling.

For other devs, it's not just a useful utility; it's inspiration. It shows how a bit of automation can glue together the fractured digital experiences we deal with daily. You might even fork it and adapt the core idea to sync other types of data trapped between apps.
