As scaling dApps enter NEAR’s mainnet, an issue may arise: how do they quickly and efficiently access state from our deployed smart contracts, and cut out the cruft? Contracts may grow to have complex data structures and querying the network RPC may not be the optimal way to access state data. The NEAR Indexer is a micro-framework specifically designed to handle real-time events on the blockchain, allowing to capture and index streams of blocks in a customized manner. With the NEAR Indexer, developers can perform both high-level data aggregation and low-level introspection of blockchain events.
For those searching to not build their own indexer, Neardata provides a hosted stream of blocks as a direct replacement for the deprecated NEAR Lake.

​
How It Works

The NEAR Indexer works by running a node and processing blocks as they are added to the blockchain. The framework provides a stream of blocks, allowing developers to subscribe and process these blocks in real-time.
Learn how to run it following the tutorial.

Comparison with NEAR Lake Framework

NEAR Lake deprecated as of March 24, 2026. The comparison below is kept for historical context. For new projects, see Neardata as a drop-in replacement for NEAR Lake.
Comparing to NEAR Lake Framework in terms of latency the NEAR Indexer is significantly faster as it reads data directly from the blockchain the same way as RPC nodes do.
