openbq-org/OpenBB
OpenBB is a free, open-source platform that connects financial data from dozens of sources — stocks, crypto, economic indicators, and more — into one unified system that analysts, AI tools, and apps can all tap into at once. Think of it as a universal power strip for financial data, so teams don't have to wire up each data source separately for every tool they build.
§ 1 — why it matters
With 75,000+ stars on GitHub, OpenBB has become a go-to infrastructure layer for fintech builders, meaning any startup building AI-powered financial tools or research products can skip months of data plumbing work by building on top of it. For investors and founders, this signals a maturing ecosystem where the commodity layer of financial data access is being commoditized, shifting the competitive advantage toward what you build on top of the data rather than how you acquire it.
§ 3 — also rising in data & analytics this week

- NanmiCoder/MediaCrawlerMediaCrawler is a tool that automatically collects public posts, videos, and comments from seven major Chinese social media platforms — including TikTok's Chinese counterpart Douyin, Xiaohongshu (like China's Instagram), Bilibili (like YouTube), and Weibo (like Twitter/X). It handles the login process automatically and can search by keyword, pull specific posts, or scrape entire creator profiles, then export the data for analysis.+741 stars this week
