Description of 0xchange.me based on their post on devpost.com:

0xchange.me is a free and open relayer in the decentralized exchange ecosystem. The goal of 0xchange.me is to provide as many order offers as possible—whether in the form of niche token ICOs, other relayers (with their fees included), or anyone interested in making a trade without transaction fees.

The tool is built with Vue.js, a Google Material template called Vuetify, and the 0x.js library. Users can make, take, and search a constantly pruned database of valid 0x orders through a user interface and an API. Additionally, the team explored techniques for scraping the blockchain for partially filled but still valid orders to offer as many options as possible. In the future, the team hopes to increase the size of its databases by waiting for other relayers to make their order books public and finding other venues for scraping valid orders.
