What if you could write code that runs for years without having to worry about interruptions like server restarts or services failing?
Welcome to that world.
Introducing Tourbillon
The next-generation durable execution environment.
Sounds fake, but it's true. Your durable programs are exposed as gRPC and HTTP (OpenAPI) APIs. Simply download their schemas and build clients for any language you want, using tools like protoc, buf, or openapi-generator-cli.
Unlike other durable execution tools, Tourbillon makes it impossible to run into non-determinism issues at runtime that can lead to corrupted execution histories. Write durable programs in Starlark — the same language used by both Bazel from Google, and Buck2 from Meta — and enjoy the peace of mind.
Version your durable programs with git, connect the reposiory to tourbillon, and evolve your code without worrying about any in-flight durable processes. They'll continue executing the code they started on.
Download a single binary and get going. Enjoy the benefits of contract-first development using protobuf. Write beautiful code with Starlark and not just a bunch of interactions with an SDK. Tourbillon exports OpenTelemetry metrics, traces, and logs, so you can use your favorite APM tool to inspect your durable proceses and tourbillon.
