Frequently Asked Questions
Flyte vs Spider Cloud: which should you choose?
Choose Flyte if you need a robust open-source orchestrator for complex, long-running ML pipelines and agentic workflows, with deep Python integration and scalable infrastructure. Choose Spider Cloud if your priority is fast, cost-effective web data extraction for AI agents and RAG pipelines, and you want a simple API without managing infrastructure.
Can Flyte be used for web scraping?
Flyte can orchestrate scraping tasks (e.g., using Python libraries) within its workflows, but it is not purpose-built for crawling. Spider Cloud is a dedicated scraping API.
Does Spider Cloud support dynamic workflows?
No, Spider Cloud is a request-response API. It does not offer workflow orchestration with dependencies, retries, or branching like Flyte does.
Which tool is easier to start with for a solo developer?
Spider Cloud is easier: sign up, get an API key, and call endpoints. Flyte requires Kubernetes setup and is better suited for teams with DevOps resources.
Can I run Flyte without Kubernetes?
Flyte officially requires Kubernetes for production. There is a local Devbox for development, but full features need a cluster.
What are the latest features of Spider Cloud in 2026?
Recent additions include Browser AI commands (Act, Extract, Observe) via WebSocket, a scraper catalog with 1,000+ examples, and data connectors to S3, GCS, Supabase.
Is Flyte free for commercial use?
Yes, Flyte is open-source under Apache 2.0, free for commercial use. Enterprise support adds cost.
Can Spider Cloud extract data from dynamic JavaScript sites?
Yes, Spider Cloud offers Browser Cloud with stealth anti-detection for JavaScript-heavy pages.
Which tool integrates with LangChain?
Spider Cloud integrates with LangChain (and many agent frameworks). Flyte does not have direct LangChain integration; it focuses on Python-based workflows.
