Silicon is an alternative to Carbon implemented in Rust.
Carbon is a wonderful tool to create a beautiful image of your source code.
But it is a web application, which brings the following disadvantages: - Cannot work without Internet & browser. - Doesn't work well with shell. (Although there is carbon-now-cli, its experience is not very good, especially when the network is not so good.)
However, Silicon doesn't have these problem. It's is implemented in Rust and can work without browser & Internet.
Silicon can render your source code one the fly while carbon-now-cli takes several seconds on it.
It's not as beautiful as Carbon...
