Barge is a shell script allowing you to run an Ocean network by orchestrating all [core components](/components) locally with Docker and Docker Compose. Extensively used by Ocean developers to develop and test Ocean core components locally, and the [quickest way](/setup/quickstart/) to get a full Ocean network up and running.
Plecos is a Python tool to check metadata (a JSON file) to see if it conforms to the [OEP-8 schema](https://github.com/oceanprotocol/OEPs/tree/master/8). It wraps the [jsonschema](https://github.com/Julian/jsonschema) validator. Aquarius uses Plecos for checking metadata and other Ocean Protocol software will probably use it in the future.
The [Ocean Protocol Faucet Server](https://github.com/oceanprotocol/faucet) is a microservice that allows users to request Ether for a particular Ethereum network (e.g. the Nile Testnet). It is [deployed in multiple networks](/tutorials/get-ether-and-ocean-tokens/#get-ether), and started by default when using [Barge](#barge).
Submarine is based on [BlockScout](https://github.com/poanetwork/blockscout) (by [POA](https://poa.network/)), an open source blockchain explorer for EVM-based blockchain networks. We use our own [fork of BlockScout](https://github.com/oceanprotocol/blockscout).
The Ocean Token Bridge between the Ethereum Mainnet and the Pacific Network allows anyone with Ocean Tokens to move them from the Ethereum Mainnet to the Pacific Network.
There are a few Ocean Protocol command-line interfaces (CLIs). All of them were under development at the time of writing, so you may have issues with using them.
The IPFS protocol is integrated into the Ocean Protocol stack in various places. For this, we run and maintain our own IPFS node and gateway with a custom frontpage for simple adding of files to that IPFS node.
