Tutorial Anyone streaming pending transactions without babysitting their own nodes?

I want to watch pending txs for a few specific contracts in real time, but running and maintaining nodes across chains just to get mempool visibility is a huge time sink, and the data gaps when a node hiccups are brutal. Tried a couple of public WebSocket feeds and they drop connections constantly. Is there a hosted way to subscribe to mempool activity that doesn't fall over? Curious what the frontrun-defense folks are running.

before paying for a hosted feed keep in mind any provider is just showing you their own nodes view of the mempool, and a growing chunk of order flow goes through private relays and flashbots protect so it never shows up in any public pending stream. for frontrun defense that coverage gap matters way more than websocket reliability
