Apibara is an open-source tool to stream and compose streams of on-chain data.
Ethereum StarknetApibara enables developers to stream on-chain data directly into their applications and power their backend infrastructure.
By connecting to blockchain data sources, it supports a broad range of data types, including events, transactions, and storage changes, enabling teams to build real-time, scalable backends without having to manage data indexing themselves.
With Apibara, you gain access to consistent, structured on-chain information across supported chains, letting you focus on application logic rather than data ingestion.
A full tutorial that gets a project indexing as quickly as possible, then explains what it built.
The defineIndexer function takes a stream definition and a handler. That pairing is the whole model.
Hooks fire at specific points in the indexing lifecycle. What each one is for, and when to reach for a plugin.
