flyteidl
IDL for Flyte Platform
Decision gist · record as of 2026-08-14
Yes, if you are building custom integrations with Flyte or need direct programmatic access to Flyte's backend API. Install it as a dependency of a higher-level Flyte client library (such as flyte-sdk) if you are a typical end user. The package is actively maintained, permissively licensed, has low install friction, and carries no known vulnerabilities.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.8 or later (supports up to 3.13); protobuf runtime is a dependency.
- Low friction install with a pure-wheel distribution.
- Actively maintained as of 2026-08-14 with regular releases; the project has 7203 stars and sits in the top 15000 PyPI packages by download volume.

What it is and what it does
Flyteidl is the core specification layer for Flyte, a workflow orchestration platform. It defines the protobuf message schemas and gRPC service interfaces that make up Flyte's backend API contract. The package contains auto-generated Python client code built from these protobuf definitions, along with the Golang clients for Flyte's administrative services.
Developers typically use flyteidl when they need to programmatically construct, serialize, or deserialize Flyte workflow specifications and API requests—either directly when building custom Flyte integrations, or indirectly through higher-level Flyte client libraries. The package depends on protobuf, googleapis-common-protos, and protoc-gen-openapiv2 to provide the runtime message handling and protocol support.
Use it for
- Building custom Flyte workflow specifications programmatically by constructing protobuf message objects.
- Integrating with Flyte's backend admin API to submit, monitor, or manage workflows and tasks.
- Developing Flyte plugins or extensions that need to interact with the platform's core data structures.
- Serializing and deserializing Flyte workflow definitions for storage or transmission.
- Generating or consuming Flyte API payloads in gRPC or REST contexts.
