Summary
Yes. The practical answer for most early-stage teams is to start on a shared or pay-as-you-go Solana RPC plan that includes WebSocket support and predictable request pricing, then move specific high-traffic workloads to a dedicated node only when you can measure the bottleneck. OnFinality offers Solana RPC API access and dedicated node options so you can scale the same endpoint setup as usage grows.
Budget is rarely the real constraint. The real constraint is matching your workload shape (read-heavy dApp, indexer, trading bot, or wallet backend) to the right plan tier, then avoiding over-provisioning before you have traffic. This article walks through how to evaluate Solana RPC providers on cost, method coverage, WebSocket behavior, and failover so you can pick a plan that fits a startup budget without painting yourself into a corner.
Solana RPC is one of the few infrastructure line items a startup can genuinely right-size from day one. You do not need the same endpoint for a wallet backend, a read-heavy dApp, and a trading bot. The trick is to match the plan tier to the workload, not to the size of the team.
This page answers the budget question directly, then gives you a way to evaluate providers so you do not overpay early or get stuck later when traffic grows.
Quick recommendation
If you are pre-revenue or early, start with a shared or pay-as-you-go Solana RPC plan that includes HTTP and WebSocket, then isolate anything that needs consistent throughput onto a dedicated node once you can measure it. OnFinality offers both tiers for Solana, so you can keep the same endpoint shape and move workloads between them without rewriting your client.
Use this as a starting rule:
| Your situation | Sensible starting tier | Why |
|---|---|---|
| Prototype, hackathon, internal tooling | Shared / public RPC | Lowest cost, fine for low request volume |
| Early dApp with real users, read-heavy | Shared RPC with a paid plan | Predictable billing, WebSocket included |
Indexer, backfill, or heavy getProgramAccounts | Dedicated node | Sustained throughput without competing for shared capacity |
| Trading bot or latency-sensitive path | Dedicated node | Consistent connection and no noisy-neighbor effects |
| Wallet or custody backend | Shared RPC + dedicated failover | Redundancy matters more than raw speed |
If you are unsure, start shared and instrument your request mix for two weeks. The data will tell you whether you need a dedicated node far more reliably than a guess will.
What actually drives Solana RPC cost
Solana pricing is not just "requests per month." Providers price on a mix of factors, and knowing which ones apply to you prevents surprise bills.
- Request volume and method weight. A
getLatestBlockhashcall and agetProgramAccountsscan are not equal. Heavy methods often cost more or are rate-limited differently. - Compute units (CU). Solana RPC providers frequently meter by compute units rather than raw call count, because some methods do far more work than others.
- WebSocket subscriptions. Persistent subscriptions (
accountSubscribe,logsSubscribe,slotSubscribe) hold server resources and are priced or limited separately from HTTP calls. - Archive and historical data. If you query old slots or transactions, you may need an archive-capable node, which sits in a different tier than a standard node.
- Dedicated capacity. A dedicated node is a fixed monthly cost rather than a metered one, which is easier to budget but only makes sense above a certain utilization.
For a startup, the goal is to keep the metered tier as long as it is cheaper than a dedicated node at your actual usage, then switch cleanly when it is not. Check current RPC pricing for the tiers that apply to your workload.
Evaluating providers without over-engineering it
You do not need a 40-row scorecard. You need to answer five questions that map directly to startup risk.
| Evaluation area | What to confirm | Startup risk if ignored |
|---|---|---|
| Method coverage | getProgramAccounts, getSignaturesForAddress, simulateTransaction, token and metadata calls | A cheap plan that blocks the one method your app depends on |
| WebSocket support | wss:// endpoint, subscription limits, reconnect behavior | Real-time features break under load |
| Transport | HTTP and WS on the same provider | You end up stitching two vendors together |
| Failover | Second endpoint or provider for redundancy | One outage takes your app down |
| Billing model | Metered vs fixed, overage rules | A viral moment turns into an unexpected invoice |
OnFinality supports HTTP and WebSocket for Solana, which means you can run standard JSON-RPC calls and subscriptions against the same provider instead of splitting your stack. See the Solana RPC API page for endpoint details.
Connecting to a Solana RPC endpoint
Once you have a plan, the connection itself is straightforward. Solana clients take an HTTP URL for standard calls and a WebSocket URL for subscriptions.
# Standard JSON-RPC call over HTTP
curl https://solana.api.onfinality.io/public \
-X POST -H "Content-Type: application/json" \
-d '{
"jsonrpc": "2.0",
"id": 1,
"method": "getLatestBlockhash",
"params": [{"commitment": "confirmed"}]
}'
In a JavaScript client such as @solana/web3.js, you point the connection at your endpoint and pass a commitment level that matches your consistency needs:
import { Connection, PublicKey } from "@solana/web3.js";
const connection = new Connection(
"https://solana.api.onfinality.io/public",
"confirmed"
);
const slot = await connection.getSlot();
console.log("Current slot:", slot);
For real-time updates, use the WebSocket endpoint rather than polling:
const ws = new WebSocket("wss://solana.api.onfinality.io/public-ws");
ws.onopen = () => {
ws.send(JSON.stringify({
jsonrpc: "2.0",
id: 1,
method: "logsSubscribe",
params: [{ mentions: ["<PROGRAM_ID>"] }, { commitment: "confirmed" }]
}));
};
ws.onmessage = (event) => {
const data = JSON.parse(event.data);
// handle log notification
};
Replace the program ID with your own. If you are testing before mainnet, use the Solana Devnet network page to get the matching endpoint and configuration.
Where startups overspend on Solana RPC
The most common budget mistakes are not about picking the wrong provider. They are about picking the wrong tier for the workload.
- Buying a dedicated node before measuring. A dedicated node is a fixed cost. If your traffic is bursty and low, a metered shared plan is almost always cheaper.
- Polling instead of subscribing. Polling
getSlotorgetSignaturesForAddressin a loop burns compute units fast. WebSocket subscriptions are usually far more efficient for change detection. - Ignoring method weight. A single unbounded
getProgramAccountscall can cost more than thousands of light calls. Add filters and usedataSlicewhere possible. - No failover plan. Running a single endpoint is a single point of failure. Even a cheap secondary endpoint is worth it for anything user-facing.
- Skipping commitment tuning. Using
finalizedeverywhere is safer but slower and can increase retries. Match commitment to the feature.
When to move from shared RPC to a dedicated node
Shared RPC is not a compromise you have to outgrow immediately. It is the correct default until one of these signals appears:
- Your p95 latency becomes inconsistent during peak hours.
- You hit rate limits or CU caps on heavy methods regularly.
- You run an indexer or backfill job that needs sustained throughput.
- You need archive data or specific method guarantees.
- You want predictable fixed monthly cost instead of metered billing.
When those signals show up, move only the affected workload to a dedicated node and keep the rest on shared RPC. This hybrid approach keeps costs low while protecting the parts of your app that need consistent capacity.
A simple monitoring setup
You cannot right-size a plan without measuring it. A minimal probe that checks latency and error rate is enough to make the shared-versus-dedicated decision.
# Lightweight health probe for a Solana RPC endpoint
for i in 1 2 3; do
curl -s -o /dev/null -w "%{http_code} %{time_total}s\n" \
https://solana.api.onfinality.io/public \
-X POST -H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","id":1,"method":"getHealth"}'
done
Track three numbers over time: error rate, p95 latency, and compute units consumed per day. When compute units approach the point where a dedicated node would be cheaper, switch. Until then, stay metered.
Key Takeaways
- Start on a shared or pay-as-you-go Solana RPC plan and move only specific workloads to a dedicated node when you can measure the need.
- Cost is driven by method weight, compute units, WebSocket subscriptions, archive access, and whether capacity is metered or fixed.
- Confirm method coverage, WebSocket support, transport, failover, and billing model before committing to a provider.
- OnFinality supports HTTP and WebSocket for Solana, so you can keep standard calls and subscriptions on one provider.
- Instrument error rate, p95 latency, and compute unit usage before upgrading tiers.
- Review RPC pricing and supported RPC networks to compare what fits your workload.
Frequently Asked Questions
Is a free or public Solana RPC endpoint enough for a startup? For prototypes and internal tools, yes. For anything user-facing with real traffic, a paid shared plan gives you more predictable limits and WebSocket support, which a public endpoint typically does not guarantee.
Do I need a dedicated Solana node from day one? Usually not. A dedicated node is a fixed cost that makes sense once your sustained usage or latency requirements exceed what a shared plan handles comfortably. Measure first.
Why does Solana RPC pricing use compute units instead of request counts? Because methods vary widely in cost. Metering by compute units reflects the actual work a call performs, so light calls and heavy scans are not priced the same.
Can I use the same provider for HTTP and WebSocket? Yes. OnFinality provides both HTTP and WebSocket endpoints for Solana, which avoids stitching two vendors together for standard calls and subscriptions.
How do I test before mainnet? Use the Solana Devnet network page to get a testnet endpoint and validate your client configuration before switching to mainnet.
