Most backends were designed for a world where humans read every line of code before it shipped. Today, though, software is being written by developers and their agents together. Codebases are growing faster than any team can review them and the assumptions that used to hold everything together are quietly eroding. Convex was built to solve that. Convex is a reactive backend platform where correctness is the default, for humans and agents alike. Transactions are ACID so concurrent writes never corrupt data, everything is TypeScript end to end so a hallucinated field name is a build error not a production incident, and sync and caching are automatic so there's no glue code to subtly rot. The guarantees engineers used to enforce by reading every line, the platform enforces instead. We're a small, in-person team in San Francisco who care deeply about what we're building and who we're building it with. Application demands are changing faster than the infrastructure underneath them, and defining what the right platform looks like for this new world is still the domain of very talented humans. We want you to be one of them.

Cockroach Labs is the creator of CockroachDB, the most highly evolved cloud-native, distributed SQL database on the planet. We help companies of all sizes — and the apps they develop — scale fast, survive anything, and thrive everywhere.

Building for the cloud is easy. Building for the edge is still way harder than it should be. Source is changing that. We're building the data management stack for edge-first software — as simple and intuitive as the best cloud tooling, with data sovereignty baked in from the start. The edge era is here. We're building the infrastructure it runs on.

Launch apps, not prototypes. Switch seamlessly between AI prompting and visual editing to build scalable web and mobile apps exactly how you envision them.
