## Basics

Learn the basics of Flyte, covering all the core concepts around tasks and apps.

### [Flyte 2](https://www.union.ai/docs/v2/flyte/user-guide/overview/page.md)

Build AI workflows in pure Python with built-in durability, reproducibility, and recovery.

### [Quickstart](https://www.union.ai/docs/v2/flyte/user-guide/quickstart/page.md)

Install the SDK and run your first workflow locally in a few minutes.

### [Core concepts](https://www.union.ai/docs/v2/flyte/user-guide/core-concepts/page.md)

The building blocks of every Flyte program: TaskEnvironments, tasks, runs, actions, and apps.

### [Run modes](https://www.union.ai/docs/v2/flyte/user-guide/run-modes/page.md)

Run the same task code locally, on a devbox, or on a remote cluster.

## Tasks

Build durable, scalable, and reproducible batch workloads.

### [Configure tasks](https://www.union.ai/docs/v2/flyte/user-guide/task-configuration/page.md)

Define `TaskEnvironment`s for container images, resources, secrets, caching, retries, and more; use triggers for schedules.

### [Build tasks](https://www.union.ai/docs/v2/flyte/user-guide/task-programming/page.md)

Compose tasks with fanout, parallelism, error handling, traces, files, and DataFrames.

### [Run and deploy tasks](https://www.union.ai/docs/v2/flyte/user-guide/task-deployment/page.md)

Use `flyte run` for iteration or `flyte deploy` to register a stable task version.

## Apps

Create long-running services to host dashboards, APIs, and model endpoints.

### [Configure apps](https://www.union.ai/docs/v2/flyte/user-guide/configure-apps/page.md)

Define `AppEnvironment`s with ports, autoscaling, custom domains, and authentication.

### [Build apps](https://www.union.ai/docs/v2/flyte/user-guide/build-apps/page.md)

Build dashboards, REST APIs, and model endpoints with FastAPI, Streamlit, vLLM, and more.

### [Native app integrations](https://www.union.ai/docs/v2/flyte/user-guide/native-app-integrations/page.md)

Use pre-built environments for popular frameworks like Streamlit, FastAPI, vLLM, and SGLang.

### [Serve and deploy apps](https://www.union.ai/docs/v2/flyte/user-guide/serve-and-deploy-apps/page.md)

Use `flyte serve` for fast iteration or `flyte deploy` for production deployments.

## Agents

Build durable, self-healing agents using tasks and apps as building blocks.

### [Build agents](https://www.union.ai/docs/v2/flyte/user-guide/build-agent/page.md)

Implement ReAct, Plan-and-Execute, and other agent patterns with full observability.

### [Agent framework integrations](https://www.union.ai/docs/v2/flyte/user-guide/agent-framework-integrations/page.md)

Integrate with third-party agent frameworks like LangGraph, PydanticAI, and OpenAI Agents SDK.

### [Sandboxing](https://www.union.ai/docs/v2/flyte/user-guide/sandboxing/page.md)

Safely execute LLM-generated code with workflow sandboxes or ephemeral containers.

### [Build an MCP](https://www.union.ai/docs/v2/flyte/user-guide/build-mcp/page.md)

Serve Model Context Protocol servers for AI assistants to interact with, hosted on Flyte.

## Advanced guides

Organize your codebase, optimize performance for production, and migrate from
other workflow orchestrators.

### [Project patterns](https://www.union.ai/docs/v2/flyte/user-guide/project-patterns/page.md)

Patterns for BYO images, monorepos with uv, CI/CD, and multi-team resource management.

### [Run scaling](https://www.union.ai/docs/v2/flyte/user-guide/run-scaling/page.md)

Tune task overhead, batching, reusable containers, and fanout to scale your workflows.

### [Advanced project](https://www.union.ai/docs/v2/flyte/user-guide/advanced-project/page.md)

An advanced guide for building an LLM reporting agent on Flyte.

### [Migration](https://www.union.ai/docs/v2/flyte/user-guide/migration/page.md)

Port a Flyte 1 codebase to Flyte 2, or map Airflow concepts to their Flyte 2 equivalents.
