# Index onchain data with Subgraphs

> Goldsky backwards-compatible subgraph indexing offers higher reliability, faster queries, webhooks, and custom EVM chain support.

Goldsky provides a fully backwards-compatible subgraph indexing service. The core of the indexing uses exactly the same WASM processing layer, but in addition, Goldsky offers:

* a rewritten RPC layer, autoscaling query layer, and storage optimizations that both:
  * improve reliability (99.9%+ uptime)
  * improve performance (up to 6x faster)
* webhooks out of the box for notifications, messaging, and other push-based use cases
* support for custom EVM chains so you can index your own rollup or private blockchain
