Let the idea
evolve

I lost motivation
Seek external feedback
Release fast
Follow KISS
Keep it simple, stupid
Don't overengineer
Values
Accessibility
Collaboration
Empowerment
Lower the learning curve
Encourage Sharing & Discovery
Stay in flow
So, what is CodeSandbox today?
And how does it work?

2. No parallelization
3. No support for emitting module
- .vue => {.css, .js, .js}
4. No chained loaders
- sass => css => css modules

Single click fork
Start in single click
No configuration
Share with a link
Customizable devtools
But for git repositories
Live collaboration
Every branch is shared
Every branch is shared
Every branch is shared
Clicking "Fork" creates new branch
Clicking "Fork" creates new branch
Every branch is backed by a VM
/:owner/:repo/main
/:owner/:repo/feature/branch
Every VM is backed by a URL
/:owner/:repo/main
/:owner/:repo/feature/branch
But you can use any editor you like
with live collaboration!
