About Flyte
Flyte is an open-source workflow orchestration platform designed for building AI, ML, and agentic workflows. Users write production-ready pipelines in pure Python without requiring a domain-specific language, enabling local development and testing before cloud deployment. The platform supports dynamic workflow execution, infrastructure-aware orchestration, and self-healing capabilities with automatic retries and failure recovery. Flyte is built for AI labs, Fortune 500 companies, and ML teams who need scalable, fault-tolerant workflows. The platform combines durable-by-default execution, built-in caching and versioning for reproducibility, and the ability to adapt workflows at runtime. One limitation is that Flyte 2's distributed execution mode requires Union.ai's enterprise platform, while the open-source version currently supports local execution.
