About TLS
Working with developer and design work no longer requires installing heavy desktop software — TLS runs entirely in your browser, instantly. Everything happens client-side, which means your files and data never leave your machine. The interface is intentionally minimal so you can focus on the task instead of learning the tool. It pairs naturally with the other developer utilities here when you need to chain a quick workflow.
