+ + + Instant Queries by Default + +
++ Try Gigabugs, our 1.2 million row bug tracker. +
++ Sync engines enable instant UI by downloading data to the client + before it's needed. All read and writes are local and synced + with the server in the background. +
++ But there's a catch: almost all realistic apps have + way too much data to download ahead of time. There are usually + complex permissions too — not all users can read and write all + data. +
++ We created Zero to solve these problems and bring the performance of + sync to the entire web. +
+Try it out right now.
++ Our Gigabugs demo has 1.2 million rows, and loads in less than + 2 seconds. +
+ +How it Works
+ +
+ Zero has two parts: a client and a server.
++ The server runs in the cloud and maintains a sync-optimized + replica of your Postgres database. +
++ On the client, you get an API that looks like an embedded + database, but to which you can issue arbitrary “hybrid queries” + that span the entire database, including the server. +
++ Behind the scenes, Zero synchronizes query results continuously to + a client-side persistent cache. This cache is used automatically + for future queries whenever possible. +

+Our Users Say
+Check out what our users have to say about Zero.
+ ++ Zero completely changed how we think about real-time. The + query-driven sync is genius — our app feels instant now. +
++ We tried building our own sync layer. Should've just used + Zero from day one. Saved us months of development time. +
++ The permission system is incredibly powerful. We can finally + give users real-time collaboration without worrying about data + leaks. +
++ Local-first with Zero means our app works offline and syncs + seamlessly. Our users don't even notice when their + connection drops. +
++ The developer experience is top-notch. Write queries, get + reactive updates. It's that simple. +
++ Zero handles the hard parts of sync so we can focus on + building features. The performance gains are unreal. +
