What Is Chainstack Ethereum RPC?
Chainstack lets developers create Ethereum RPC endpoints without running their own node. Apps can use those endpoints to query blockchain data, call smart contracts, send transactions and connect to Ethereum mainnet or testnets.
Chainstack’s Ethereum page describes its product as geo-balanced Ethereum RPC infrastructure built for consistent performance worldwide. It also supports both Global Nodes and Dedicated Nodes, so teams can start free and upgrade when traffic or reliability needs grow.
Chainstack Free Tier Snapshot
| Feature | Chainstack Developer Plan |
|---|---|
| Monthly price | $0/month |
| Included requests | 3,000,000 |
| Throughput | 25 requests/second |
| Nodes | 1 |
| WebSockets | Included |
| Support | Community support |
| Credit card | Not required |
| Trial limit | No time limit, no trial |
Chainstack measures usage in request units. Its Ethereum page lists a full node request as 1 request unit and an archive node request as 2 request units. That makes it easier to estimate usage compared with providers that use more abstract credit systems.
Why Developers Choose Chainstack
- Free plan with no trial limit
- 3 million monthly requests
- WebSocket endpoint support
- No credit card required
- Simple pricing compared with compute-unit systems
- Global Node and Dedicated Node upgrade paths
- Ethereum mainnet and testnet support
Main Limitations
Chainstack’s free tier is clean, but it is smaller than some credit-heavy plans from providers such as Alchemy or Infura. The Developer plan is best for prototypes, low-traffic tools and early-stage apps.
Teams that need archive data, dedicated nodes, higher throughput, Debug and Trace APIs, enterprise support or guaranteed production performance should compare the paid Growth, Pro, Business or Enterprise plans.
Best Use Cases
Chainstack is best for:
- Ethereum dApp prototypes
- Wallet testing
- DeFi dashboards
- Smart contract scripts
- WebSocket-based event monitoring
- Developers who want a free endpoint without a short trial clock
It is less ideal as the only RPC provider for high-volume production systems. Serious apps should use monitoring, retries and backup providers.
Chainstack vs Alchemy and Infura
Chainstack is strongest when you want a simple, predictable free tier. Alchemy is better for teams that want broader developer APIs and dashboard tooling. Infura is better for developers who prefer a long-running Ethereum infrastructure brand with a daily free credit model.
If you only need a stable free Ethereum RPC endpoint to build and test, Chainstack is one of the cleanest choices.
Final Verdict
Chainstack is a top free Ethereum RPC provider in 2026 because its Developer plan is easy to understand: $0/month, 3 million monthly requests, 25 RPS, 1 node and WebSockets. It is not the largest free allowance, but it is one of the clearest free plans for developers who want to build without committing to a paid tier.
