# Quickstart
## Try BigchainDB
Create a BigchainDB transaction and post it to a BigchainDB network in 20 seconds or less:
## Develop an App
To develop an app that talks to a BigchainDB network, you'll want a test network to test it against. The BigchainDB Test Network (or "Testnet") is a free-to-use, publicly-available BigchainDB network that you can test against. You can find out more about the BigchainDB Testnet on [the BigchainDB "Get Started" page](https://www.bigchaindb.com/developers/getstarted/#server).
Regardless of which BigchainDB network you use, you'll probably use one of the [BigchainDB drivers or tools](https://www.bigchaindb.com/getstarted/#drivers).
## Help Develop BigchainDB Server
