Offline-first apps: why your downloader shouldn't need the cloud

A surprising number of apps require a live internet connection for tasks that have nothing to do with the internet — opening a previously downloaded file, viewing your own settings, browsing things you already saved. We build the opposite way by default.

Offline-first means the network is an enhancement, not a requirement

The core idea is simple: anything that doesn't strictly need a live connection shouldn't be blocked by a missing one. Your downloaded files should open instantly with no spinner waiting on a server that has nothing to do with opening a local file.

It's a better experience on good connections too

Offline-first apps tend to feel faster everywhere, not just offline, because they're not built around waiting for round-trips to a server for things that could be instant. A flaky train Wi-Fi connection and a fast home connection both benefit from an app that doesn't assume the network is always there and always fast.

It's also a privacy benefit

An app that can function fully offline for its core features is, by necessity, an app that isn't constantly phoning a server with your activity. There's a natural privacy upside to architecture that doesn't require checking in just to do something local.

Sync, when it exists, should be optional and visible

Where we do offer cloud sync (for backup or cross-device convenience), it's opt-in, not the default mechanism the app secretly depends on to function. You should be able to say no to sync and still have a fully working app.

The tradeoff is real engineering effort

Offline-first is genuinely harder to build than "just call the API every time." It means thinking through caching, local storage, and what happens when connectivity comes back, instead of assuming a constant connection. We think that effort is worth it because it's the difference between an app that respects your situation and one that assumes everyone has fast, unlimited, always-on internet — which isn't actually true for a large share of our users.

Good offline support is invisible when it's working. You only notice it the one time you needed it and it just worked.
