How to use this guide
Turn the topic into a decision note.
Use this before you put app traffic on a public endpoint or a paid RPC plan. The useful output is a short workload note, not a vendor logo.
List reads, writes, logs, WebSockets, archive/debug calls, retries, and burst traffic before comparing plans.
Look for the metric that will break first: compute units, RPS, method support, support response, or fallback coverage.
Write down who owns provider alerts, status checks, migration, and the backup endpoint before users depend on it.
What is an archive node?
An archive node stores historical blockchain state so apps can query older balances, contracts, and state transitions that normal endpoints may not keep.
What to check next
Confirm whether your provider includes archive methods on the chain and plan you expect to use.
Common mistake
Do not assume every RPC plan can answer old state queries just because it supports current balances.
What to do after this guide
Compare at least two relevant products, open the source links, and write down the owner for pricing, support, compliance, security, accounting, or launch questions. The best tool depends on those constraints, not on a generic ranking.
