The service is excellent in and of itself, but the support response and communication is equally as good.
Dear LS, Thank you for the review. We’re glad both the service and our support team have delivered a strong experience. Clear, responsive communication is just as important to us as reliable infrastructure. Warm regards, Customer Success Team
quick response, I just suggest to implement the API roatation inside the website that could be more quickly if some data could be leaked and patch it immediately
Dear Aqtis, Thank you for the review. We’re glad our team came across as friendly and understanding — we aim to keep support human, clear, and helpful. Warm regards, Customer Success Team

Dear Mike, Thank you for the review. Glad the Chainstack experience was useful and helped you understand how it works — if you have questions as you explore further, our team is here to help. Warm regards, Customer Success Team
Best Solana service. Growth plan has amazing CU quotas for buidlers! Support is best in class compared to other web3 Infra providers. Chainstack always replies me in minutes, not days (like Alchemy). For sure the most stable Ethereum beacon API with most accurate data!
Dear Jeremy, Thanks for the detailed feedback. Great to hear Solana performance has been strong for you, the Growth plan CU quotas fit your build needs, and our support response times have been consistently fast. Appreciate the note on Ethereum Beacon API data quality as well. Warm regards, Customer Success Team
I’ve been using Chainstack’s Geyser gRPC for streaming Solana data and it’s been rock‑solid. Setup was straightforward, the stream stayed stable during bursts, and latency was consistently low for our indexing pipeline. Docs + examples got us productive quickly, and support answered a couple of edge‑case questions fast.
Dear Alexey, Thanks for sharing this. Great to hear the Solana Geyser gRPC stream has been stable through bursts with consistently low latency, and that the docs/examples made setup quick. Appreciate the note on support helping with edge cases — we’ll keep investing in both performance and developer experience. Warm regards, Customer Success Team
Chainstack has been rock-solid for production: reliable endpoints, predictable performance, and clear docs. When things get tricky, support is responsive and actually helpful. It’s the kind of infra you stop worrying about.
Dear Aleksandar, Thank you for the review. We’re glad Chainstack has been reliable in production for you — predictable performance, clear documentation, and support that helps when things get complex is exactly what we aim to deliver. Warm regards, Customer Success Team
I have used Chainstack many times for my pet projects related to telegram bots, reading smart contracts through RPC, reading balances, and data indexing. Everything worked excellently everywhere, was cheap and stable.
Dear Kirill, Thank you for the feedback. Glad Chainstack has been dependable across your projects (RPC reads, balances, and indexing) and that you found it stable and cost-effective. Warm regards, Customer Success Team
Nodes started dropping connections, became unreliable to the point that they are now unusable. Was great before but not anymore. Their free allowance was good for developers but it is no longer worth the service unreliability headache. Already have issues with filters dropping, add to that random node disconnections, no thank you. As a developer, I have better things to do than trying to implement code workarounds for chainstack infrastructure limitations. Time to move on.

Our team is actively working on improving our infrastructure to address these very concerns, including connection stability and filter consistency. We understand how frustrating this can be, especially when you rely on our service for your development work.

Terrible quality, the RPC nodes work when testing but after they get your money, it all turns to trash. Performed terrible on the same benchmarks shortly after paying. Unreliable customer support, if you paid with crypto you basically get scammed.

I tried their 1 usd trial, and cancelled it soon after. Then i was charged today, and after downgrading i was told no refund and my plan is now downgraded from all benefits. So they bamboozle you into paying anyway, and getting none of the benefits. Would not recommend, oh and btw their RPC are slower than most competitors.

Absolutely garbage service quality, worse than free services. And when you ask for a refund, they'll tell you to downgrade the account to free tier, then tell you that you can't have a refund. Basically, they will rug you of your service access and money.
