QuickNode alternatives

QuickNode's moat is a Marketplace of specialized add-ons layered on a shared node fleet. For the head-lag axis the two products that matter are Streams and the Solana gRPC add-on (Yellowstone-compatible Geyser). Streams is a push pipeline: blocks, receipts and traces flow through a JavaScript or Go filter function and land in a webhook or storage destination, with exactly-once delivery in finality order. Streams supports 81 chains including Ethereum, Solana, Bitcoin, Arbitrum, Base, Polygon and Avalanche. The Solana gRPC add-on exposes a Geyser plugin stream directly, which is the same interface Solana validators emit internally; that path bypasses the JSON-RPC serialization tax and is why Yellowstone consumers land trades faster than REST or WS pollers on Solana. Swap-specific decoding is delegated to Marketplace add-ons (0x Swap API, Metis Jupiter, Pump Fun API, Aerodrome, Velodrome), each billed separately. QuickNode wins for teams that want raw block-level control plus a Solana Geyser feed on one bill; teams that want a single decoded cross-chain DEX event stream have to compose several Marketplace SKUs, which raises integration and latency budget.
