The 5 Best Sui RPC Providers in 2026: gRPC, GraphQL, and Pricing Compared

The Sui Foundation switched off JSON-RPC on its own mainnet full nodes the week of July 27, 2026, and plans to remove the code entirely in mid-October 2026. That change landed on a busy network: DeFiLlama figures reported in July 2026 put Sui's DeFi TVL back above $1 billion, after a record $2.6 billion in October 2025. A Sui node provider runs the full nodes, indexers, and archival services your app reads from, so you can query and transact without syncing your own hardware. After the shutoff, the first question for any Sui RPC provider is whether it serves gRPC, GraphQL RPC, and archival data.

The best Sui node provider for multi-chain teams in 2026 is NOWNodes. It offers shared and dedicated Sui mainnet nodes with a gRPC API, a 99.95% uptime SLA, no RPS limits on paid plans, and 24/7 support with a stated three-minute first response. It fits wallets, payment processors, and explorers that run Sui alongside dozens of other chains. Teams that need Sui GraphQL RPC, testnet endpoints, or a permanent free tier will find a better match in QuickNode, Ankr, or BlockVision.

Here is a list of the top Sui RPC providers in 2026:

1. NOWNodes

2. QuickNode

How We Ranked the Best Sui Node Providers

Our editorial team evaluated each provider as a team migrating a production Sui app off JSON-RPC would. We checked the Sui Foundation's provider table, each vendor's Sui documentation, and each public pricing page.

• Network Coverage and Node Types. Which Sui interfaces and networks are served, and whether shared and dedicated nodes are both available.

• Performance and Reliability. Published uptime commitments, throughput limits, regional footprint, and failover behavior.

• Pricing and Support. Free tier terms, entry price, billing unit, and how quickly an engineer responds.

Sui RPC Provider Comparison Table

The table below compares all five Sui RPC providers on the features that matter most after the JSON-RPC deprecation.

Rates, supported chains, and limits change frequently. Verify current terms on each provider's official site before committing.

1. NOWNodes

Best for: multi-chain wallets and payment services that add Sui to an existing stack.

NOWNodes is a node infrastructure provider based in Tallinn, Estonia, covering more than 120 blockchains from one API key. Its sui rpc page lists shared and dedicated mainnet access alongside a gRPC API, the interface most teams now need after the JSON-RPC shutoff. Paid plans carry a 99.95% uptime SLA and no predefined RPS limits. It suits teams that already route Bitcoin, EVM, and other traffic through one vendor and want Sui on the same bill.

Network Coverage and Node Types. NOWNodes serves Sui mainnet on shared and dedicated infrastructure, with RPC and gRPC access. Testnet and GraphQL RPC are not listed, which rules the service out for teams building their frontend on Sui's GraphQL layer. NOWNodes also does not yet appear in the Sui Foundation's provider table, so confirm gRPC method coverage in a trial before migrating.

Performance and Reliability. Shared traffic runs through geo-distributed, load-balanced clusters in the US and EU, with automatic failover when a node drops, and dedicated nodes can go in any region. The company cites roughly 200 ms average response time and 15,000 transactions per second of platform throughput. Those are vendor figures, and the larger providers publish more independent benchmark data.

Pricing and Support. The free Start plan includes 100,000 requests, but it runs for one month and covers a limited set of networks. Paid tiers have flat pricing based on your plan, not compute usage. Pro starts at 1 million requests, and every request costs the same, whether it’s a gRPC call or a balance read. Support runs 24/7 on every plan with a stated three-minute first response.

2. QuickNode

Best for: teams that want gRPC, GraphQL, and archive data on Sui from a single endpoint.

QuickNode is a Miami-based blockchain API provider founded in 2017 that serves 80+ chains. On Sui it runs all three post-JSON-RPC interfaces. Archive queries route automatically to archive nodes when data falls outside the 14-epoch full node window. It fits product teams that want the complete Sui data stack from one account.

Network Coverage and Node Types. QuickNode serves gRPC on Sui mainnet and testnet, while GraphQL and archive access run on mainnet only. Archive data is reached through gRPC. Dedicated Clusters are reserved for the Enterprise plan.

Performance and Reliability. Sui mainnet endpoints run in the EU and US, but archive traffic is served from the US only. Throughput is capped per plan, from 15 RPS on the trial to 500 RPS on Business. Contractual uptime SLAs appear only on Enterprise.

Pricing and Support. The free option is a one-month trial with 10 million API credits. Paid plans start at $49 per month for 80 million credits. Credit multipliers vary by method and Sui gRPC data is metered separately, which makes bills harder to forecast than flat per-request pricing. Ticket support starts with a 24-hour response SLA on Build.

3. Ankr

Best for: teams that want cheap pay-per-call gRPC access to Sui.

Ankr has operated Web3 infrastructure since 2017 and runs its RPC service on a bare-metal network across many regions. The Sui Foundation lists Ankr with gRPC on mainnet and testnet, plus GraphQL RPC and archival service on mainnet. That puts it level with QuickNode on Sui interface coverage. It suits cost-conscious teams that prefer usage-based billing.

Network Coverage and Node Types. Ankr covers the full new Sui data stack, and its quickstart guide shows gRPC and GraphQL endpoints side by side. Shared endpoints are self-serve. Dedicated deployments go through the Enterprise sales track rather than a published price list.

Performance and Reliability. The Premium plan advertises 1,500 RPS, the highest published shared ceiling among the metered providers here. Freemium accounts stay on public rate limits and receive HTTP 429 errors when they exceed them. Ankr documents its service reliability terms in a dedicated SLA page.

Pricing and Support. Freemium gives 200 million API credits per month at no cost. Premium uses a prepaid balance at $0.10 per million credits, and a Sui HTTPS call costs 200 credits, or $20 per million requests. gRPC costs 10 credits per call plus $0.50 per GB of bandwidth, so payload size decides the real bill. Freemium users get community support, while Premium adds a support portal.

4. Triton One

Best for: DeFi protocols and indexers that need low-latency Sui streaming.

Triton One is best known for Solana infrastructure, but it was part of Sui's original validator set and supports only Solana, Sui, and Monad. On Sui it offers gRPC streaming, an archival service covering the ledger from genesis, and Walrus and Seal endpoints. Every feature is included on every account. It suits teams that care more about latency and engineer access than chain count.

Network Coverage and Node Types. Triton serves Sui mainnet and testnet on shared pools and dedicated bare-metal nodes in North America, Europe, and APAC. Its Sui gRPC streaming is still labeled beta. Triton's own page calls GraphQL "coming soon," while the Sui Foundation table lists it as live, so check before planning around it.

Performance and Reliability. Shared pools use GeoDNS routing, automatic failover, and cross-region backup pools. Triton markets 99.99% uptime, though that reads as a marketing figure rather than a published contractual SLA. Rate and connection limits are set per customer instead of per tier.

Pricing and Support. Triton has no free tier. Access starts with a $125 prepaid, non-refundable deposit valid for 12 months. Standard RPC and unary gRPC calls cost $10 per million plus $0.08 per GB of bandwidth. Every endpoint includes a direct channel to senior engineers instead of a ticket queue.

5. BlockVision

Best for: small Sui dApps that want a permanent free tier and low fixed pricing.

BlockVision is a Sui-focused data platform that also runs the SuiVision explorer. It pairs Sui RPC and gRPC nodes with an indexing API for coins, NFTs, and DeFi positions. Plans are fixed monthly subscriptions with published request counts. It fits early-stage Sui teams and dashboard builders who value indexed data over raw throughput.

Network Coverage and Node Types. The Sui Foundation lists BlockVision with gRPC on mainnet and testnet, but without GraphQL RPC or an archival service. Sui gRPC is excluded from the free plan, and the Sui Indexing API is available only on Pro. BlockVision does not publish a dedicated-node offer.

Performance and Reliability. Throughput is the main constraint. Sui rate limits run from 5 requests per second on Free to 40 on Pro, which is low for a busy trading frontend. BlockVision does not publish an uptime SLA in its rate-limit documentation.

Pricing and Support. Each Sui RPC or gRPC call costs a flat 50 compute units, which makes budgets easy to plan. The free plan gives 200,000 Sui requests per month with no time limit. Paid plans run $29 for 2 million requests, $99 for 12 million, and $199 for 40 million.

How to Choose a Sui RPC Provider

The JSON-RPC shutoff turned provider selection into a migration project. Work through these steps in order.

• Map your calls to gRPC or GraphQL. Sui's documentation points frontends and filtered historical queries to GraphQL, and streaming and ingestion to gRPC.

• Check the Sui Foundation provider table. It shows which interfaces each vendor has enabled per network.

• Confirm archival access if you read old data. Full nodes prune history, and gRPC does not fall back to archival data on its own.

• Price your real method mix. Credit-based plans can weight one Sui call at 50 or 200 units, so convert quotes into cost per million requests.

• Test throughput at your peak. A 40 RPS cap and a no-limit plan look identical at idle and very different during a token launch.

• Ask who answers at 3 a.m. Response targets range from minutes to 24 hours across these five vendors.

Editor's assessment: in 2026 the deciding factor is rarely raw speed; it is whether a provider already serves the exact Sui interfaces your migrated code calls. Pilot two providers with production-representative traffic before committing.
