Flyte is a structured programming and distributed processing platform that enables highly concurrent, scalable, and maintainable workflows for Machine Learning and Data Processing. It is a fabric that connects disparate computation backends using a type-safe data dependency graph. It records all changes to a pipeline, making it possible to rewind time. It also stores
a history of all executions and provides an intuitive UI, CLI, and REST/gRPC API to interact with the computation.
Flyte is more than a workflow engine -- it uses workflow as a core concept, and task (a single unit of execution) as a top-level concept. Multiple tasks arranged in a data
producer-consumer order creates a workflow.
Workflows and Tasks can be written in any language, with out-of-the-box support for Python, Java and Scala.
Flyte was designed to manage the complexity that arises in Data and ML teams and ensure they keep up their high velocity of delivering business impacting features. One way it achieves this is by separating
the control-plane from the user-plane. Thus, every organization can offer Flyte as a service to their end-users where the service is managed by folks who are more infrastructure-focused, while the users use the intuitive interface of Flytekit.
- Kubernetes-Native Workflow Automation Platform
- Ergonomic SDK's in Python, Java & Scala
- Versioned, Auditable & Reproducible Pipelines
- Data Aware and Strongly Typed
- Resource Aware and deployed to scale with your organization
With Docker installed and Flytectl installed, run the following command:
flytectl sandbox startThis creates a local Flyte sandbox. Once the sandbox is ready, you should see the following message: Flyte is ready! Flyte UI is available at http://localhost:30081/console.
Visit http://localhost:30081/console to view the Flyte dashboard.
Here is a quick visual tour of the console:

- Used at Scale in production by 500+ on one deployment. Used in production at multiple firms. Proved to scale to more than 1 million executions, and 40+ million containers
- Data Aware and Resource Aware (Allows organizations to separate concerns - users can use the API, platforms/infra teams can manage the deployments and scaling)
- Enables collaboration across your organization by:
- Executing distributed data pipelines/workflows
- Making it easy to stitch together workflows from different teams and domain experts and share them across teams
- Comparing results of training workflows over time and across pipelines
- Simplifying the complexity of multi-step, multi-owner workflows
- Get Started quickly -- start locally and scale to the cloud instantly
- gRPC / REST interface to define and execute tasks and workflows
- Typesafe construction of pipelines -- each task has an interface characterized by its input and output, so illegal construction of pipelines fails during declaration, rather than at runtime
- Supports multiple data types for machine learning and data processing pipelines, such as Blobs (images, arbitrary files), Directories, Schema (columnar structured data), collections, maps, etc.
- Memoization and Lineage tracking
- Provides logging and observability
- Workflow features:
- Start with one task, convert to a pipeline, attach multiple schedules, trigger using a programmatic API, or on-demand
- Parallel step execution
- Extensible backend to add customized plugin experience (with simplified user experience)
- Branching
- Workflow of workflows - subworkflows (a workflow can be embedded within one node of the top-level workflow)
- Distributed remote child workflows (a remote workflow can be triggered and statically verified at compile time)
- Array Tasks (map a function over a large dataset -- ensures controlled execution of thousands of containers)
- Dynamic workflows creation and execution with runtime type safety
- Flytekit plugins with first-class support in Python
- Arbitrary Flytekit-less containers tasks (RawContainer)
- Guaranteed reproducibility of pipelines via:
- Multi-cloud support (AWS, GCP, and others)
- No single point of failure, and is resilient by design
- Automated notifications to Slack, Email, and Pagerduty
- Multi K8s cluster support
- Out of the box support to run Spark jobs on K8s, Hive queries, etc.
- Snappy Console & Golang CLI (Flytectl)
- Written in Golang and optimized for jobs that run for a long period of time.
- Grafana templates (user/system observability)
- Deploy with Helm and Kustomize
- Containers
- K8s Pods
- AWS Batch ArrayJobs
- K8s Pod Arrays
- K8s Spark (native Pyspark and Java/Scala)
- AWS Athena
- Qubole Hive
- Presto Queries
- Distributed Pytorch (K8s Native) -- Pytorch Operator
- Sagemaker (builtin algorithms & custom models)
- Distributed Tensorflow (K8s Native)
- Papermill notebook execution (Python and Spark)
- Type safe and data checking for Pandas dataframe using Pandera
- Versioned datastores using DoltHub and Dolt
- Use SQLAlchemy to query any relational database
- Build your own plugins that use library containers
- Snowflake queries

We run a suite of tests to ensure that basic functionality and a subset of the integrations work across a variety of release versions. Those tests are run in a cluster where specific versions of the Flyte components (such as flyteconsole, flyteadmin, datacatalog, and flytepropeller) are installed, including the released versions and also the latest versions in the case of the nighly runs.
The table below has different release versions as the columns and the result of each test suite as rows:
| workflow group | nightly | v0.19.1 | v0.19.0 | v0.18.2 |

Flyte is a Community Driven and Community Owned Software. It is managed using a steering committee and encourages collaboration. The community has a long roadmap for Flyte, but they know that there might be some other interesting ideas, extensions or additions that you may want to propose. This is done usually starting with a
- Github Issue - We maintain issues for all repos in the main flyte repo.
- Writing down your proposal using a Documented RFC process
For small changes, RFCs are not required, but for larger changes, RFC's are encouraged. You are welcome to drop into the Slack channel and talk to the community, if you want to test the waters, before proposing.
Here are some resources to help you learn more about Flyte.
