## Product

### Similarities

* **Subgraph compatibility**: Both Goldsky and Alchemy are fully compatible with the open source `graph-node` specificiation

### Differences

Goldsky provides additional value-add functionality on top of the standard subgraph experience:

* **[Tags](/subgraphs/tags)**: Hotswap subgraphs versions seamlessly, allowing for zero-downtime updates on your frontend
* **[Webhooks](/subgraphs/webhooks)**: Send real-time notifications from subgraph updates to a webhook, enabling advanced, push-based use cases
* **[Mirror connectivity](/mirror/sources/subgraphs)**: Stream your subgraph data into a database of your own for custom analytics and processing. This enables significant additional power and flexibility (eg. [cross-chain subgraphs](/subgraphs/guides/create-a-cross-chain-subgraph))
* **Load-balanced RPC network**: We use multiple RPC vendors with a variety of underlying node clients, leading to improved reliability and performance

## Pricing
