Alchemy vs. Infura Comparison

Alchemy and Infura are two blockchain node providers that help web3 startups build dapps without running their own nodes.

Choosing the right blockchain node provider is a crucial step in the web3 development process, as you want to use a developer platform that offers the most cost-effective requests, the best tools, reliable service, accurate data, and the ability to scale on demand to grow with your project.

What is Alchemy?

Alchemy provides blockchain APIs and node infrastructure, supporting over 10 million end users and powering some of the world's top blockchain apps, including OpenSea, Trust Wallet, and 0x, and the largest web2 companies, such as Shopify and Adobe.

Alchemy offers a suite of developer tools to help developers build, debug, and ship products faster and monitor dashboards to track errors, user insights, and trends.

Alchemy is one of the biggest venture-backed startups in web3 with investors including Pantera, Coatue, A16z, Redpoint, Lightspeed, Coinbase, and some of the most accomplished individuals in tech, including Naval Ravikant, Peter Thiel, and Reid Hoffman.

Alchemy Supernode is the infrastructure engine that powers some of the world's top blockchain apps. It offers a one-line infrastructure API that does all the jobs of a single node and comes with the uptime, availability, and necessities to run a production application. The architecture uses dedicated distributed systems to power each node functionality and maintains real-time data correctness with a proprietary coordinator service.

‍
What is Infura?

Infura is another popular blockchain node provider offering APIs and developer tools for building on web3, focusing on Ethereum, Ethereum Layer 2s, Polygon, and IPFS.

Infura is owned by ConsenSys, a software development company founded by Joe Lubin, an original co-founder of Ethereum. ConsenSys also owns projects such as MetaMask, an Ethereum wallet, and Truffle, a blockchain development environment.

Infura uses a cloud architecture model, including syncing directly from object storage, a parity backend that runs in AWS Elastic Container Service (ECS), and a "Source of Truth" node that creates a snapshot of chain data and pushes it to an S3 bucket.

Next, we'll dive in deep on 9 key factors to consider when evaluating Alchemy and Inufra.

1. Supported Blockchains

When searching for a new node provider, companies should consider the networks supported by providers to ensure that they support their current app, the chains they want to expand to immediately, and the chains on the provider's roadmap.

Alchemy supports the following 8 blockchain networks:

• Ethereum

• Optimism

• Arbitrum

• Polygon PoS

• Starknet

• Solana

• Polygon zkEVM

• Base

• Astar (Polkadot)

Alchemy supports the following testnets:

• Goerli (Ethereum, Optimism, Arbitrum)

• Sepolia (Ethereum)

• Mumbai (Polygon)

Infura supports the following additional blockchains::

• Avalanche

• Aurora

• NEAR

• Palm

• Celo

• Linea

Alchemy and Infura both support multiple blockchains. Choosing one option versus the other should depend on whether either of them supports your primary and secondary expansion chains.

For example, Alchemy would be a good choice if you're looking for a Solana RPC provider, whereas Infura would be better if you want to build a dapp on Avalanche.

2. Node Latency

There are two kinds of blockchains latency. Block discovery latency is the amount of time a node provider uses to discover a new block, and request latency is the time difference between sending a blockchain request and receiving a response.

Alchemy engineers recently conducted a side-by-side comparison of Alchemy and Infura to measure request latency.

In this test, we queried eth_blockNumber and measured the time between the origination of the request and the receipt of the response on the Ethereum mainnet. We then aggregated and averaged this number across approximately 250 total queries, each at 15-minute intervals for Alchemy and Infura.

In our most recent test, August 12th, 2022 - August 15th, 2022, Alchemy averaged 39.96 ms, and Infura averaged 38.18 ms for the US East location.

While Infura's request latency is 4% faster than Alchemy's in this test, Alchemy's secondary infrastructure, such as synchronizing 30% of Ethereum nodes before confirming a block, offers web3 developers higher guarantees for data accuracy, node reliability, and scalability.

3. Data Accuracy

It is essential for node providers to provide users and dapps with accurate blockchain data, as incorrect information can negatively impact the web3 user experience:

1. Requests return different answers to the same question

2. Dapps retrieve incorrect transaction nonces

3. Users have a poor experience when tokens and NFTs appear incorrectly
   

In a recent data accuracy benchmarking experiment, we queried eth_blocknumber on the Ethereum mainnet over 1 million times in 24 hours and found that Infura returned 705 inaccurate block numbers, while Alchemy returned 0 inaccuracies.

Alchemy Supernode allows Alchemy's API to act as a single node, enabling 100% accuracy. This is achieved with an explicit consistency layer called Vox Nodi, a consensus algorithm that allows each node to vote on the data it receives, and the data is only returned to the user when it is accurate.

While Infura has 4% lower request latency than Alchemy, returning blockchain information faster at the expense of data accuracy can lead to a degraded web3 user experience.

4. Node Reliability

Node reliability is a measure of uptime, and it is an important category to compare when choosing a node provider because it directly impacts a dapp's ability to serve customers at any time of the day.

Alchemy and Infura both have highly reliable systems. However, when examining historical uptimes on each node provider's status page, we find that, on average, Alchemy's systems have better uptime. 

The node reliability status page shows the following comparisons for the Ethereum Mainnet from January 2022 to July 2022.

• January - Alchemy (100%) vs. Infura (100%)

• February - Alchemy (100%) vs. Infura (99.98%)

• March - Alchemy (100%) vs. Infura (99.97%)

• April - Alchemy (99.97%) vs. Infura (99.91%)

• May - Alchemy (100%) vs. Infura (100%)

• June - Alchemy (100%) vs. Infura (100%)

• July - Alchemy (99.92%) vs. Infura (99.99%)

In addition to overall uptime, there have been historical outages on Infura that have rendered many dapps including MetaMask wallets unusable, even though the main Ethereum network was operational.

In November 2020, Infura experienced a 7-hour outage that impacted millions of users due to a bug that affected their nodes running geth v1.9.9 and v1.9.13, two outdated versions of the geth node client. As recently as April 2022, Infura experienced a 3-hour outage due to an internal configuration change.

5. Pricing

Compared to Infura, Alchemy provides approximately 400% more free requests per month than Infura's free tier, does not cap Archive node access, and doesn't require users to add a credit card on file to access Layer 2s, and sidechains like Optimism, Polygon, and Arbitrum.
