Alchemy is one of the best Ethereum RPC providers for developers who want a free, reliable starting point for Web3 apps. It is especially useful for wallets, DeFi dashboards, NFT tools, analytics scripts and backend services that need Ethereum data without running a self-hosted node.
Quick answer: Alchemy is the best overall free Ethereum RPC provider in our main ranking because its free tier includes Node API access, full archive data, Smart WebSockets, analytics and several developer APIs.

What Is Alchemy Ethereum RPC?
Alchemy’s Node API gives developers low-level blockchain access through Ethereum-compatible JSON-RPC methods. That means an app can read balances, fetch blocks, call smart contracts, track logs, estimate gas or submit signed transactions through an Alchemy endpoint.
Alchemy also supports many other networks, but its Ethereum RPC product is one of the most common entry points for developers building on Ethereum mainnet or testnets such as Sepolia.
Alchemy Free Tier Snapshot
| Feature | Alchemy Free Tier |
|---|---|
| Base compute units | 30 million |
| Apps | 5 |
| Ethereum Node API | Included |
| Full archive data | Included |
| Smart WebSockets | Included |
| NFT, Transfers and Token APIs | Included |
| Debug API | Not included |
| Trace API | Not included |
| Support | Email support |
Alchemy uses compute units instead of counting every request equally. A simple request such as checking the latest block is lighter than a heavy log query. This is useful because Ethereum apps often mix small reads with more expensive data calls.
Why Developers Choose Alchemy
- Strong free tier for prototypes and small apps
- Clean dashboard and usage analytics
- Ethereum JSON-RPC support through the Node API
- Smart WebSockets for live data workflows
- Archive data on the free tier
- Extra APIs for NFTs, token data and transfers
- Easy upgrade path when an app grows
Main Limitations
Alchemy’s free plan is generous, but it is not unlimited. Developers who need heavy transaction tracing, advanced debugging, dedicated support, higher throughput or guaranteed service-level commitments may need a paid plan.
The biggest free-tier limitation is that Debug API and Trace API access are not included. That matters for analytics teams, block explorers, advanced DeFi monitoring tools and developers investigating complex transaction execution.
Best Use Cases
Alchemy is best for:
- Ethereum dApp frontends
- Wallet prototypes
- NFT dashboards
- DeFi analytics tools
- Smart contract scripts
- Event monitoring with WebSockets
- Small production apps with sensible retry logic
It is less ideal as the only RPC dependency for high-volume production systems. Serious apps should use monitoring, retries and backup RPC providers.
Final Verdict
Alchemy is the best free Ethereum RPC provider for most developers in 2026. Its free tier is practical, its dashboard is easy to use, and its Ethereum tooling goes beyond a basic RPC URL. The main reason to upgrade is scale: once an app needs tracing, deeper support or higher traffic capacity, the paid tiers become more relevant.
