Whale Alert alternative for large bitcoin transaction data

Whale Alert is a real-time large-transaction feed: it streams big transfers across many blockchains as they happen, with exchange attribution, and publishes the well-known alerts on social media. Its dashboard has a free tier and a paid Alerts and Analytics plan around $29.95 per month, and its API is aimed at trading firms, with real-time transaction data and about 30 days of history; specific API tier pricing is quoted on request. If you want a ready-made, push-style feed of whale moves across many chains, Whale Alert does that well.

The reason a team looks for a Whale Alert alternative is usually control and history. You may want to define what a whale is yourself, in BTC or dollars, go back further than a rolling 30-day window, or run the data through SQL rather than react to a fixed feed. BitcoinDatabase is that layer for Bitcoin: the fully-indexed chain over a REST API, SQL and webhooks, where you set your own large-transaction threshold, label both ends to strip out exchange shuffles, and rebuild the entire history of big moves rather than a recent slice. It is Bitcoin-native and query-first rather than a multi-chain broadcast feed, on usage-based paid plans, and everything is informational on-chain data, not a trading signal or investment advice.
