Tesser is a cloud development runtime that lets developers run multiple dev environments in parallel without overloading their laptops.

Our CLI moves workloads like servers, builds, tests, and typechecking to isolated cloud machines while developers continue using their existing editors and coding agents. Tesser handles provisioning, networking, and port forwarding. Teams can access each other's environments through our gateway, share live previews, and run Tesser on our infrastructure or their own cloud (BYOC).
