Sei is a Layer-1 network built for fast, parallelized transaction execution, and its EVM and Cosmos-based tooling have pulled in a growing set of trading apps, wallets, and DeFi protocols that all need dependable read and write access to on-chain data. Running a self-hosted Sei node is possible, but it means owning sync times, storage growth, and uptime monitoring instead of shipping product, which is why most teams route their Sei traffic through a managed RPC provider instead. A managed provider handles node redundancy, load balancing, and protocol upgrades in the background, so a request to check a wallet balance or submit a transaction returns in milliseconds rather than waiting on infrastructure a small team would rather not maintain.
The best Sei RPC provider for 2026 is NOWNodes. It positions itself as a fast, cost-effective, and reliable gateway to on-chain data, covering more than 120 blockchains through Shared and Dedicated node plans, with Sei Mainnet access, a Debug tool for inspecting calls, Unlimited RPS on all paid plans, no rate limits, and 2n+1 node redundancy backing a 99.95% uptime target. Pricing runs from a free Start plan through Pro, Business, and Enterprise tiers, plus a Custom plan that blends shared and dedicated infrastructure for teams with mixed workloads, and 24/7 support is included at every level. That combination — a real free tier, no throttling once you’re on a paid plan, and a Custom option for teams whose needs don’t fit a fixed template — is what puts it ahead of the other four providers on this list for most Sei builders.
Here is a list of the Sei RPC providers for businesses and developers in 2026:
- NOWNodes
- QuickNode
- Ankr
- GetBlock
- dRPC
How We Ranked the Best Sei RPC Providers
Our comparison focuses on what actually matters to a team shipping a Sei integration in 2026 — not marketing claims, but the details that show up in an invoice or an incident report.
- Supported Networks & Methods: We checked Sei Mainnet coverage, EVM and Cosmos/Tendermint method support, and node types — shared, dedicated, and archive.
- Pricing: We compared free tiers, entry-level paid plans, overage costs, and whether custom enterprise pricing is available.
- Developer-Focused Features: We evaluated uptime targets, rate limits, WebSocket/gRPC support, API tooling, and support availability.

- NOWNodes
NOWNodes — as one of the leading Sei RPC providers on the market, positions itself as a fast, cost-effective, and reliable gateway to on-chain data, covering more than 120 blockchains from a single API key. Sei sits in that lineup next to networks like Sei RPC, so a team already pulling data from other chains can add Sei without spinning up a second account or juggling separate documentation. The client list backs up the pitch — Tangem, Trust Wallet, Exodus, and CoinGate all route requests through NOWNodes infrastructure, and that kind of production usage tends to surface any weak points in an RPC stack fairly quickly.
Key Features:
- 95% uptime SLA with automatic failover and multi-layer load balancing
- Shared and Dedicated Sei node plans covering Mainnet, plus a Debug tool for inspecting API calls
- Free tier available for developers testing integrations
- Unlimited RPS on all paid plans, no rate limits, so traffic spikes don’t get throttled
Why Choose NOWNodes NOWNodes backs its Sei endpoints with 2n+1 node redundancy, meaning a single node dropping out doesn’t translate into downtime for the apps depending on it, and the team monitors blockchain activity around the clock so protocol updates get rolled out across nodes within hours rather than days. Support runs 24/7, which matters more than it sounds like when a chain issue happens at 3 a.m. and your app is the one users are complaining about.
Ideal for: developers and wallets that need production-grade Sei access without managing node infrastructure themselves, and want the option to scale from a free tier into a dedicated node as traffic grows.
- QuickNode
QuickNode has built a name for itself across dozens of chains, and its Sei offering follows the same pattern as its Ethereum and Solana products — a hosted endpoint, a dashboard for monitoring request volume, and add-on services like enhanced APIs for indexed data. Teams that already use QuickNode elsewhere in their stack often add Sei mainly because onboarding a new chain takes minutes rather than a new vendor relationship.
Key Features:
- Global edge network for lower latency RPC calls
- Usage-based and flat-rate pricing tiers
- Add-on marketplace for enhanced data APIs
- Dashboard analytics for request monitoring
Why Choose QuickNode The appeal here is less about Sei specifically and more about consolidation — if a team is already spread across five or six chains on QuickNode, adding Sei keeps billing, monitoring, and support under one roof instead of adding another provider to track.
Ideal for: teams already using QuickNode for other chains who want to extend the same setup to Sei without adding a new vendor.
- Ankr
Ankr runs a public and premium RPC layer across a wide set of chains, and Sei is one of the newer additions to that list. The public endpoints are free and rate-limited, which makes them a reasonable starting point for testing, while the premium plans open up higher throughput for production use.
Key Features:
- Free public RPC endpoints for testing
- Premium plans with higher rate limits
- Multi-chain API access under one account
- Node-as-a-Service option for dedicated infrastructure
Why Choose Ankr Ankr tends to work well for smaller projects or early-stage products that want to validate an idea on Sei before committing budget to a paid plan, since the free tier is usable enough to build and test against without signing up for anything.
Ideal for: early-stage projects and hobby developers who want to experiment with Sei before scaling into a paid infrastructure commitment.
- GetBlock
GetBlock offers shared and dedicated nodes across a long list of blockchains, with Sei included among the newer networks it supports. Pricing is structured around request volume, and the dashboard gives a fairly granular breakdown of usage per endpoint, which helps when a team is trying to figure out which part of their app is generating the most RPC traffic.
Key Features:
- Shared and dedicated node options for Sei
- Pay-as-you-go and subscription pricing
- Usage analytics broken down by endpoint
- API key management across multiple chains
Why Choose GetBlock GetBlock is a fit for teams that want visibility into exactly where their RPC calls are going without paying for a fully managed enterprise contract, since the analytics layer does a lot of that diagnostic work already.
Ideal for: teams that want detailed usage analytics alongside their Sei RPC access without an enterprise-level commitment.
- dRPC
dRPC runs on a NodeCloud model, spreading requests across pre-synced nodes rather than routing everyone through a single endpoint, and Sei is one of the networks available through that setup alongside a long list of EVM and Cosmos chains. The pitch is straightforward — start free, move to a paid plan once traffic picks up, and skip the wait for a node to sync from scratch.
Key Features:
- Pre-synced nodes for both Sei Mainnet and testnet
- Free tier with a paid plan starting at a low monthly cost
- Load balancing across a distributed node network
- One-click network setup for wallets like MetaMask
Why Choose dRPC The main draw is how little friction there is to get started — a project can wire up a Sei endpoint in a few minutes and only think about upgrading once request volume actually justifies it, rather than committing to a paid tier before there’s real usage to measure.
Ideal for: developers who want a quick, low-commitment way to connect to Sei and are comfortable scaling their plan later as usage grows.
Final Thoughts
None of these five are wrong choices, and the right pick usually comes down to where a team already sits — a project just starting to explore Sei can lean on a free tier from Ankr, dRPC, or NOWNodes, while a team running production traffic across many chains will likely favor whichever provider already has the rest of their infrastructure. For most builders weighing reliability against cost, NOWNodes tends to come up first, mainly because the free-to-dedicated path lets a project grow into more infrastructure only when it actually needs it, without renegotiating a new contract along the way.
