# Tapeboard > A professional-grade market terminal that runs in the browser. Free to start, transparent methodology, no $24,000/year subscription. Tapeboard is a professional-grade market terminal for retail traders, individual investors, finance students, and anyone who needs institutional-grade market intelligence without the institutional-grade bill. Twelve modules — real-time scanner, charts with 50+ indicators, macro economic data, SEC filings, insider trades, short squeeze leaderboard, crypto order books, forex, bonds, options chains, news, and an economic calendar — run in a single browser tab. Differentiator: Tapeboard publishes the full methodology behind every score and metric, sources are cited inline, and the free tier covers most retail use cases — at a fraction of the cost of a professional terminal subscription. ## Public data products Full data products updated daily and intended for both human and AI consumption.
