RPC Providers

Introduction
Solana makes use of independent nodes which have the responsibility of working to confirm programs and outputs of programs on one of the three Solana clusters, Devnet, Testnet or Mainnet Beta. A cluster is made up of a set of validators that work to confirm transactions. These are owned and operated by individuals. These nodes are also responsible for storing data and transaction history which is shared amongst the nodes. A node can become a validator node if it is being used to vote on valid blocks and if SOL is delegated to the validator identity it can become a leader node. This is the link to the information on how to become a validator.
Not all nodes can become leader nodes or vote to confirm blocks. They still serve the other functionalities of validator nodes, but since they cannot vote they are primarily used to respond to requests on the blockchain. These are RPC nodes. RPC stands for remote procedure call, and these RPC nodes are used to send transactions through the blockchain.
Solana maintains three public API nodes, one for each cluster which are Devnet, Mainnet Beta, and Testnet. These API nodes are what allow users to connect to the cluster. To connect to Devnet users can look at:
https://api.devnet.solana.com
This is the node for Devnet, and it is rate limited.
In the Mainnet Beta cluster, many developers choose to use their own private RPC node to take advantage of higher rate limits not avalible to them from Solana's public API nodes.
For Mainnet Beta in the picture above, from the Solana Docs, we can view the rate limits from using the mainnet api node.
We will proceed to define two types of RPC nodes and then present you with several options. We recommend you choose one based on your project's needs.
Archive and Nonarchive Nodes
We can divide nodes into two different categories. The first one we will look at are the Archive nodes. These can store information of previous blocks. In the case of these archival nodes, we can leverage having access to all previous blocks in several ways. Some of the advantages include being able to view an address's balance history and view any state in the history. Due to the high system requirements of running a full historical node, having private nodes available with this feature is highly beneficial.
Unlike archival nodes, a non-archive node, or just a regular node, will only have access to some of the previous blocks, which is upwards of 100 blocks. We previously mentioned that running an archival node has intensive requirements, but even a non-archive node can become hard to manage. For this reason, users often choose a private RPC provider. Most use cases involving private RPCs in Solana usually revolve around Mainnet-beta uses since this involves real SOL tokens, and there is a higher chance of being rate limited.
RPCs Available
The following section includes multiple RPC providers.
Note This list is in alphabetical order. Please choose the RPC provider that best suits your project's needs. If we are missing a provider, let us know in our discord or submit a PR.
Alchemy
Alchemy offers a free plan with a rate limit of 12 million transactions per month. Their plan is to keep it free for the first 500 people who sign up to use it. Once you sign up, you will have access to the private RPC they provide.
From this image you will notice they have a request counter which is setup to help you confirm your RPC is working.

Their dashboard also allows you to test the RPC through several methods such as using the public address of your wallet which you can get from your terminal with:
solana address
// output
DZCjxxxxxxxxx
And input it into their tester with getbalance option chosen for the following result which includes the token balance and time taken to respond:
