Flyte vs Prefect — Comparison

Flyte

Dynamic, resilient AI orchestration. 80M+ downloads.

The most intuitive, developer-loved way to orchestrate AI workflows in open source. Now available for local execution. Dynamically orchestrate complex, long-running, and agentic workflows with autoscaling and infrastructure awareness. Write workflows in actual Python, no need to learn a DSL. Write, test, and version workflows locally, then run them at scale. Build fault-tolerant, resilient workflows that retry automatically, pick up where they leave off, and make failures inconsequential. Build durable AI/ML pipelines and agents with OSS. Build and scale dynamic AI/ML workflows using Flyte’s open-source platform and community. Author in pure Python to provision and scale resources for workflows. Workflows can make on-the-fly decisions at runtime with real-time logic, conditions, and retries. Workflows can autonomously recover from failures and continue where they left off. Test and debug tasks in your local environment using the same Python SDK that runs in production on Kubernetes. The enterprise Flyte platform. Build scalable AI and agents in your cloud. Everything in Flyte 2 OSS, plus: Massive scale at 50k+ actions/run Massive scale and ultra-low latency to accelerate AI from experiment to production Orchestrate, deploy, and optimize AI/ML systems one unified platform. Serve performant agents and models with sub-second latency. Debug remote tasks, line-by-line, on the actual infrastructure where your tasks run. Reusable, warm-start containers Achieve task startup time of 100ms by eliminating cold starts. Get visibility into resource usage, data lineage, and versioning. Get dedicated help from a team of expert AI engineers. Build dynamic, self-healing workflows in open source. Our infra-aware platform orchestrates data, models, compute. Author dynamic, production workflows in pure Python. No DSL required. Develop and debug locally before deploying to production. Built-in caching and versioning ensure fast, repeatable runs. Render plots and visualize data with reports. Promote workflows to cloud or on-prem without infra complexities. Build truly agentic workflows with stateful execution with automatic failure recovery. Autoscale compute dynamically to match workload demand. Run Spark jobs on ephemeral clusters. Pytorch-native multi-node distributed training. Connect to Ray cluster to perform distributed model training and hyperparameter tuning. Best in class ML/AI experiment- and inference-time tracking. Orchestrate, ship, and scale AI systems from experiment to production. Union.ai’s platform accelerates teams through AI orchestration, training, real-time inference, and observability.
