Is there a free TradingView alternative?
Yes. Narwhal Free includes 3,000 successful requests per month, commercial app use and both REST and hosted MCP access. A single key connects your own interface to observations and economic release dates.
Does the Charting Library include market data?
No. TradingView's documentation says you must supply a datafeed. Advanced Charts is free for public websites, while Trading Platform has licensing fees. Decide separately how to draw charts and how to obtain the underlying observations.
What changes in my application?
Replace the request URL and authentication, then map the JSON response into your application's fields. The examples use standard fetch in JavaScript and requests in Python, so integration fits an ordinary HTTP client. Keep your key on the server and carry the response's units, dates and missing values into your display or calculations.
What happens at Narwhal's monthly limit?
The shared cap applies to successful REST and MCP requests together. There are no automatic overage charges. Basic includes 100,000 monthly requests; quotas reset each month even when you pay yearly.
