JustScreener is a cryptocurrency market-monitoring platform that helps users identify notable price moves and trading conditions without choosing coins in advance. Every minute, it checks more than 7,100 trading pairs across 10 exchanges, around the clock, and can send matching alerts to a phone or desktop, or through Telegram. Users set conditions such as sharp price changes, open-interest spikes, unusual turnover, extreme funding rates, price levels, liquidations, or technical signals.

The service offers screeners and bots for price, open interest, funding, funding arbitrage, turnover, and custom criteria. Alerts include a coin-specific breakdown with market indicators, such as price and volume changes, funding, long-to-short balance, and comparisons with recent averages. JustScreener also provides market analytics and tools, including heatmaps, a Fear & Greed Index, DeFi information, exchange announcements, and calculators for liquidation price, funding, position size, futures profit and loss, and average entry. The platform offers seven days of free full access, followed by one alert per day at no charge.
