# Deploy a PFN

{% hint style="info" %}
**Do I have to run a PFN?**\
If you do not wish to run a PFN, but still want to interact with the Aptos blockchain, you can use the REST API provided by the Aptos Labs’ PFNs (see [Aptos APIs](https://aptos.dev/en/build/apis)). Note, however, that Aptos Labs-provided PFNs have rate limits, which can impede your development. If you want to avoid such rate limits, you can deploy your own PFN and synchronize with the Aptos blockchain directly.

Select the guide for the deployment method you prefer:

**Choose a network**\
These guides default to deploying a PFN in the Aptos mainnet network, but they can easily be used to do the same in other networks (e.g., devnet or testnet network). To do so, check out the desired network branch and use the `genesis.blob` and `waypoint.txt` node files for the respective branches: [mainnet](https://aptos.dev/en/network/nodes/configure/node-files-all-networks/node-files-mainnet), [devnet](https://aptos.dev/en/network/nodes/configure/node-files-all-networks/node-files-devnet), and [testnet](https://aptos.dev/en/network/nodes/configure/node-files-all-networks/node-files-testnet).
