Software and data for people who manage their own money

StockMarketStack is a catalogue of 3 market data APIs, charting platforms, portfolio trackers, backtesting frameworks and trade journals. Every card is filled in against a fixed schema, so the comparison tables are generated from the same fields you read on the card — and 0 of them were tested with our own keys rather than summarised from a vendor’s landing page.

No brokers, no robo-advisors, no stock picks. Tools only.

Everything with an MCP server

Which market data providers and research tools can an LLM call directly? Nobody else tracks this, so we do.
