Seven exchanges,
one charting workspace

Trading across exchanges means juggling tabs

You have a Binance account and a Bybit account. Maybe Kraken for fiat rails, KuCoin for a long-tail alt, OKX because the futures market there is deeper. Each exchange has its own web interface, its own charts, its own quirks. You bounce between four browser tabs just to sanity-check a price.

Aggregator tools exist, but most of them pull their data through a third-party provider — which means extra latency, occasional mismatches with the exchange's own feed, and monthly bills for data you could be getting directly.

TabChart connects directly to each exchange

Each supported exchange exposes a public WebSocket API for market data. TabChart speaks to each of them directly — no proxy, no data aggregator, no API keys involved (public market data doesn't need them). When you pick an exchange in the app, you're getting the same feed the exchange serves to its own web frontend.

Switching exchanges is instant. Your chart tabs, indicators, and preferences stay intact — the app reconnects the feeds, the charts repopulate, and you're reading the new exchange's markets within a second.

Why "direct" actually matters

Most multi-exchange tools route through a data provider — CryptoCompare, CoinAPI, or their own aggregation server. That adds a hop, a caching layer, and a source of drift. On quiet markets you won't notice. On fast-moving ones, the aggregator's price and the exchange's own book can diverge by a few seconds.

When you're looking at a chart to decide whether to place an order on that exchange, you want to see what that exchange is actually showing its own users. Direct WebSocket connections make that the default.

What the multi-exchange workflow gets you

• One workspace, seven exchanges. No more switching between browser tabs. Switch exchanges in-app in a click.
• Direct WebSocket per exchange. No proxy, no aggregator, no API keys needed for charting.
• Same charts, same screener. The preset layouts and screener work identically across every supported exchange.
• Pair coverage follows the exchange. Whatever pairs the exchange lists, TabChart can chart. Long-tail alts included.
• No account required. Install, pick an exchange, start charting. Nothing to sign up for.
• Your data stays local. Connections are between your machine and the exchange. No TabChart-side analytics logging what you watch.
