Question 1

What is the difference between a shared and a dedicated node?

Accepted Answer

A shared node serves many customers from a common pool and bills by usage. A dedicated node is a private server reserved entirely for you, billed at a flat rate with no usage cap. Shared favors flexibility and low cost; dedicated favors performance, control, and isolation.

Question 2

What is a compute unit?

Accepted Answer

A compute unit is the usage metric for Shared Nodes. Different RPC methods cost different amounts of CU, with data-heavy calls costing more than simple reads. Your plan includes a monthly CU allowance, and Limitless and Dedicated Nodes remove CU counting entirely.

Question 3

When should I move off Shared Nodes?

Accepted Answer

Move when you regularly exhaust your CU allowance, hit the RPS ceiling, need archive or tracing methods continuously, or have compliance needs. If your volume is predictable, Limitless is usually the next step; if you need custom configuration or maximum performance, go to Dedicated.

Question 4

Is Limitless Node cheaper than a dedicated node?

Accepted Answer

Yes. Limitless Node provides isolated capacity and unlimited requests within an RPS tier at roughly five to ten times less than a comparable dedicated setup. The difference is the RPS ceiling, which most production workloads never actually reach.

Question 5

Can I change plans as my application grows?

Accepted Answer

Yes. Shared tiers upgrade instantly, Limitless tier changes take effect immediately with no lock-in, and a Dedicated Node can be resized before you hit a hardware ceiling, usually within the same billing cycle.
