Feedback from teams evaluating Chainstack alongside Alchemy for pricing, performance, and production RPC workloads.
I was already using Alchemy's API, but their pay-as-you-go pricing is too high for me. I decided to try Chainstack's monthly subscription, and so far, so good.
I am pretty happy with the Chainstack experience so far and will definitely think of keeping using it over Alchemy!
Both are definitely better than Alchemy nodes that I also tested
So far your service is showing transactions considerably faster than other options I've tried (publicnode, drpc, alchemy). You are beating the next best option by a median of 500ms. You also forward a higher percentage of landed transactions.
The Growth plan delivered exactly that. Fast, no gaps, no silent empty responses. The backfill completed cleanly.
