R0Y (pronounced "Roy") is a no-code financial studio where you describe the analysis you want in plain English and it builds interactive investing dashboards instantly. Ask for "a momentum backtest on NVDA vs. SPY over 3 years" or "macro correlation between rate hikes and emerging market ETF drawdowns" and R0Y assembles a live, interactive system with real data from hundreds of millions of data points — no SQL, no Python, no Bloomberg terminal required. The platform connects to market data, economic indicators, and financial databases to generate projections, strategy models, and backtesting frameworks on demand. Dashboards are shareable with team-specific customization, making it useful for investment clubs, family offices, and individual traders who want institutional-grade analysis without the institutional-grade tooling cost. It's free to start with a freemium model. Launched on Product Hunt this week and hit the top three on launch day. The interface is built on React with KlineCharts for financial visualization, Supabase for backend, and Google's generative AI — a surprisingly capable technical stack for what appears to be an early-stage indie project.

Reviewer scorecard
“Natural language to working financial dashboards with real data is a workflow most analysts spend days setting up. If the data sources are solid and the backtest logic is sound, this is legitimately useful. The free tier makes it easy to evaluate before committing.”
“Built-in vectorizer modules mean less glue code. GraphQL API is intuitive. Self-hosting option is a huge plus.”
“AI-generated backtests with 'hundreds of millions of data points' is exactly the kind of marketing language that hides survivorship bias and look-ahead bias. Any serious investor knows that a backtest is easy to generate and almost meaningless without rigorous methodology — this could give beginners false confidence in bad strategies.”
“Open source and self-hostable gives you an exit strategy. The module system is genuinely innovative.”
“Democratizing quantitative finance is a decade-long trend that's now accelerating rapidly. R0Y is part of a wave that will eventually let retail investors run the kind of macro analysis that hedge funds pay analysts six figures to produce. The direction is right even if early versions are imperfect.”
“Multi-modal vectors and generative search point to where databases are heading. Weaviate is building for that future.”
“The ability to generate a shareable interactive dashboard from a natural language prompt is genuinely exciting for anyone who writes financial content or manages a Substack portfolio tracker. No more fighting with Sheets or Notion embeds.”
