Page	What you'll find
Indexing Overview	Accessing and processing blockchain data efficiently is crucial for building responsive dApps, wallets, analytics tools, and other off-chain services on Ergo.
Explorer Stack	Explorer-style deployments are indexer stacks, not node replacements.
Explorer API	One of the simplest ways to access indexed Ergo blockchain data for your dApp or service is by utilizing the public APIs provided by blockchain explorers.
Node API (Direct)	Another approach to accessing blockchain data is to run your own Ergo node and query its REST API directly from your application.
Custom Indexer	For many production dApps and services on Ergo, building a custom off-chain indexer provides the optimal balance of performance, query flexibility, and control over data.
