Cold start in
17 milliseconds.

We combine Google's state-of-the-art V8 JavaScript engine, process-level snapshots, and Rust to speed up everything from cold start to runtime performance.


Handle data and use external APIs, easily.

Blueboat comes with support for encoding, parsing, and transforming different kinds of data, and provides native access to popular external services. All built-in and implemented in Rust, so you don't have to pull in heavy third-party JavaScript libraries.

Secure and efficient multi-tenancy.

Apps are isolated from each other with multiple layers of security: V8 isolates, user and process boundaries, and seccomp. With efficient copy-on-write fork() on Linux, we are able to reduce multi-tenancy overhead to a minimum.
