Vantafin has three plans: Free, Pro, and Ultimate. The right choice depends on whether you need live data, AI tools, and API/WebSocket access, or whether delayed research data is enough. This guide compares them so you can decide quickly. You can always start free and upgrade later.

When Free is enough
Choose Free if you mainly want to:
- Research companies with profiles and SEC filings.
- Read market news and delayed quotes.
- Keep a single watchlist.
Free is a great way to explore the platform before deciding.
When to upgrade to Pro
Choose Pro if you want the full research and building toolkit:
- Live quotes across the app.
- AI Chat grounded in real filings and data.
- Alerts on price, filings, and news.
- Unlimited watchlists and the full screener.
- REST API and MCP server access.
Pro is billed monthly or annually; annual billing lowers the effective monthly price. See exact prices on pricing.
When to choose Ultimate
Choose Ultimate if you need:
- WebSocket streaming for real-time quotes, news, filings, and halts.
- The highest limits on API calls per minute, AI Chat questions, alert notifications, and file storage.
Ultimate is aimed at active developers and power users building on live data.
