OpenStock open-sources real-time trading app

On May 25, RoundtableSpace pushed an open-source stock-market app called OpenStock into the retail-trader feed on X, with links to a live demo and GitHub. The pitch was simple: real-time market data, TradingView charts and no subscription wall. (github.com) What is verifiable from the project itself is broader than the social post. The GitHub repository describes OpenStock as “an open-source alternative to expensive market platforms,” and says it lets users track prices, set alerts and review company information. The live site describes it as “forever free.” (github.com) The repo also makes clear this is not just a front-end mockup. OpenStock is built with Next.js, uses MongoDB for persistence, Better Auth for authentication, Finnhub for market data and TradingView widgets for charts and market views, according to the project README. (github.com) A few details matter if you are trying to understand why traders noticed it: - Real-time data: The project says it uses Finnhub for market data. (github.com) - Charting: It uses TradingView widgets, which gives it a familiar chart layer for active market users. - Open-source license: The repository is under AGPL-3.0, which means anyone running a modified networked version must also release source code under the same license terms. - Traction: The GitHub page showed about 11.5K stars and 1.6K forks when checked, suggesting the project had already attracted a sizeable developer audience. That last point is important context. OpenStock was not a same-day code dump created only for a viral post. The repository was already public and had been active for months, with recent commits still landing as of about three weeks before May 25. (github.com) There are also limits to the “free Bloomberg for everyone” framing that often follows projects like this. The project materials describe OpenStock as a market-tracking platform, not a brokerage, and note that market data can be delayed depending on provider rules and configuration. In other words, the app’s promise is transparency and accessibility, but the exact data experience can still depend on upstream feeds. (gitee.com) The practical takeaway is narrower and more concrete: OpenStock packages live prices, alerts, company pages and TradingView-based charting into a public codebase that users can inspect, self-host or adapt. For retail traders, that is why the X post traveled. For developers, the more relevant fact is that the stack, license and deployment path are already visible. (github.com) If you want to follow what happens next, the two places to watch are the Open-Dev-Society/OpenStock GitHub repository for commits and issues, and the openstock-ods.vercel.app demo for feature changes.
