# Streaming

Real-time on-chain data is the lifeblood of modern Web3 applications. We offer a suite of powerful streaming solutions, each tailored to a specific use case—from simple frontend notifications to the high-throughput, low-latency demands of MEV searchers and trading bots.

Streaming data from Solana requires a high-bandwidth Internet connection and a fast client environment. Frequent disconnections are a sign of a weak client setup. See our [Streaming Troubleshooting Checklist](https://docs.triton.one/chains/solana/streaming/streaming-troubleshooting-checklist) for helpful tips.

#### Dragon's Mouth (gRPC)

**The fastest way to get real-time on-chain data.** Dragon's Mouth is a gRPC interface powered by Geyser, streaming account and transaction updates directly from Solana validators.

* **Best for:** Backend applications, high-frequency trading bots, MEV searchers, and any system where milliseconds matter.
* **Key Feature:** Provides **intra-slot updates**, delivering data up to 400ms faster than standard WebSockets by showing you state changes as they happen, not just at the end of a slot.
* **Note:** gRPC is not supported in web browsers and is intended for server-to-server communication.

#### Whirligig (WebSockets)

**A better, faster, stronger WebSocket.** Whirligig is a high-performance, drop-in replacement for Solana's standard WebSocket API, built on top of our Dragon's Mouth gRPC streams.

* **Best for:** Web3 frontends, real-time user interfaces, and easily upgrading existing applications that already use WebSockets.
* **Key Feature:** Offers the same **intra-slot update** advantages as gRPC but over a browser-compatible WebSocket connection, making your dApp feel significantly more responsive.

#### Fumarole (Reliable Streams)

**A persistent, "never miss an event" streaming solution.** Fumarole is designed for applications where guaranteed data delivery is absolutely critical.

* **Best for:** Accounting systems, compliance tools, analytics platforms, and any application that needs a complete and verifiable history of events.
* **Key Feature:** Allows your client to disconnect and reconnect to the stream at a later time, automatically backfilling any data that was missed. It also supports horizontal scaling via consumer groups.
