 ## Summary
 
 [Sonic](https://github.com/valeriansaliou/sonic) is a super fast auto-suggestion engine built by the team at [crisp.chat](crisp.chat), a customer engagement platform. it is built in Rust and they officially support a javascript client, but if you want to use sonic via PHP, this is the library that you can look for.
