Developer Assistance Tools

Developer Assistance Tools (CelesBox) is a suite of 37 developer utilities in seven categories: data, text, API, security, media, diagrams and dev. It runs entirely in the browser. There is no backend and no account: every tool does its work on your machine, and the site is designed so that no data leaves the browser.

• Getting started: what the product is and how to open a tool.
• Tools: the seven categories and every tool in them.
• Self-hosting: the offline package and the container image.
• Feature switches: leaving feature modules out of a build.
• Security and privacy: what the site does to keep your data in the browser.
