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.
Do I need WebSocket RPC or is HTTP enough?
HTTP is enough for many read and write flows. WebSockets help when an app needs live subscriptions, events, new blocks, or near-real-time updates.
What to check next
Document which screens or jobs need live updates and test reconnect behavior under network changes.
Common mistake
Do not add WebSockets just because they sound advanced; they add state, retries, and monitoring requirements.
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.
