Restate provides a distributed durable version of your everyday building blocks, letting you build a wide range of use cases: * [Workflows-as-Code](https://docs.restate.dev/use-cases/workflows) * [Microservice orchestration](https://docs.restate.dev/use-cases/microservice-orchestration) * [Event Processing](https://docs.restate.dev/use-cases/event-processing) * [Async Tasks](https://docs.restate.dev/use-cases/async-tasks) * [Agents, Stateful Actors, state machines, and much more](https://github.com/restatedev/examples) ## Get started with Restate 1. 🏎 [Follow the Quickstart](https://docs.restate.dev/get_started/quickstart) to get Restate up and running within 2 minutes! 1. 💡 [The Tour of Restate](https://docs.restate.dev/get_started/tour) walks you through the most important features of Restate. ## SDKs Restate supports the following SDKs: * [Typescript](https://github.com/restatedev/sdk-typescript) * [Java and Kotlin](https://github.com/restatedev/sdk-java) * [Python](https://github.com/restatedev/sdk-python) * [Go](https://github.com/restatedev/sdk-go) * [Rust](https://github.com/restatedev/sdk-rust) ## Install We offer pre-built binaries of the CLI and the server for MacOS and Linux. Have a look at the [Quickstart](https://docs.restate.dev/get_started/quickstart) or [installation instructions in the docs](https://docs.restate.dev/develop/local_dev). ### Install the server Install via Homebrew: ```bash brew install restatedev/tap/restate-server ``` Run via npx: ```bash npx @restatedev/restate-server ``` Run via docker: ```bash docker run --rm -p 8080:8080 -p 9070:9070 -p 9071:9071 \ --add-host=host.docker.internal:host-gateway docker.restate.dev/restatedev/restate:latest ``` ### Install the CLI Install via Homebrew: ```bash brew install restatedev/tap/restate ``` Install via npm: ```bash npm install --global @restatedev/restate ``` Run via npx: ```bash npx @restatedev/restate ``` You can also download the binaries from the [release page](https://github.com/restatedev/restate/releases) or our [download page](https://restate.dev/get-restate/). ## Community * 🤗️ Join our online community on [Discord](https://discord.gg/skW3AZ6uGd) or [Slack](https://join.slack.com/t/restatecommunity/shared_invite/zt-2v9gl005c-WBpr167o5XJZI1l7HWKImA) for help, sharing feedback and talking to the community. * 📖 [Check out our documentation](https://docs.restate.dev) to get started quickly! * 📣 [Follow us on Twitter](https://twitter.com/restatedev) for staying up to date. * 🙋 [Create a GitHub issue](https://github.com/restatedev/restate/issues) for requesting a new feature or reporting a problem. * 🏠 [Visit our GitHub org](https://github.com/restatedev) for exploring other repositories. ## Core primitives The basic primitives Restate offers to simplify application development are the following: * **Reliable Execution**: Restate guarantees code runs to completion. Failures result in retries that use the [Durable Execution mechanism](https://docs.restate.dev/concepts/durable_execution) to recover partial progress and prevent re-executing completed steps. * **Reliable Communication**: Services communicate with exactly-once semantics: whether it's [request-response, one-way messages, or scheduled tasks](https://docs.restate.dev/concepts/invocations). Restate reliably delivers messages and uses Durable Execution to ensure no losses or duplicates can happen. * **Durable Promises and Timers**: Register Promises/Futures and timers in Restate to make them resilient to failures (e.g. sleep, webhooks, timers). Restate can recover them across failures, processes, and time. * **Consistent State**: Implement [stateful entities](https://docs.restate.dev/concepts/services) with isolated K/V state per entity. Restate persists the K/V state updates together with the execution progress to ensure consistent state. Restate attaches the K/V state to the request on invocation, and writes it back upon completion. This is particularly efficient for FaaS deployments (stateful serverless, yay!). * **Suspending User Code**: long-running code suspends when awaiting on a Promise/Future and resumes when that promise is resolved. This is particularly useful in combination with serverless deployments. * **Observability & Introspection**: Restate includes a UI and CLI to inspect the [state of your application](https://docs.restate.dev/operate/introspection) across services and invocations. Restate automatically generates Open Telemetry traces for the interactions between handlers. ## Contributing We’re excited if you join the Restate community and start contributing! Whether it is feature requests, bug reports, ideas & feedback or PRs, we appreciate any and all contributions. We know that your time is precious and, therefore, deeply value any effort to contribute! Check out our [development guidelines](/docs/dev/development-guidelines.md) and [tips for local development](/docs/dev/local-development.md) to get started. ## Versions Restate follows [Semantic Versioning](https://semver.org/). You can safely upgrade from a Restate `x.y` to `x.(y+1)` release without performing any manual data migration, as Restate performs an automatic data migration for you.
