TinyFish Launches BigSet: An Open-Source Multi-Agent System That Builds Structured Live Datasets from Plain-English Descriptions

- TinyFish dropped BigSet, an open-source multi-agent system that turns plain-English prompts into structured CSVs. It’s not magic; it’s just Claude Sonnet inferring schemas and Qwen orchestrating parallel sub-agents to scrape the web. You type “YC companies hiring,” and it builds the table. No more writing brittle scrapers that break when a site changes its CSS. It’s self-hostable via Docker, uses TinyFetch for data, and caps sub-agents at 6 tool calls to prevent budget blowouts. Finally, a tool that automates the tedious parts of data engineering without requiring a PhD in regex. If you’re still manually copying Excel cells in 2026, you’re doing it wrong.
