In order to improve the efficiency when using the computer, I’m sure you have installed many efficiency tools, such as uTools, Raycast, Alfre, etc.

For program developers, in addition to some system operation enhancements, there are more requirements such as JSON formatting / conversion to XML / YAML, BASE64 coding and decoding, testing regular expressions, JWT parser / generator, timestamp conversion, text comparison / extraction / encryption and decryption / escaping, HTTP testing, etc. And He3 Universal Development Toolkit can do almost everything in one software!

He3 Universal Development Toolbox - A collection of free programming aids
As we know, most developers will search online for various “online tools” when they need such tools, or download small software with corresponding functions to find many solutions. However, He3 (Helium 3) Toolbox is a desktop application that is a “development gadget collection” for developers, and it is almost a “one for all”! It’s a one-stop shop for all your needs, so you don’t have to go looking for tools for temporary needs, which is very convenient. The interface of He3 is beautiful and the experience is very good.

“The He3 Development Toolbox is completely free and cross-platform for Windows, Mac, and Linux. It has more than 400 useful tools for program development, including JSON, YAML, date and time, text, image, color, coding, encryption and decryption, network, programming, web page, and other categories.

Whether you’re a front-end or back-end engineer, or even if you’re not a developer but a productivity-focused office user, the He3 toolkit includes many tools that are useful for office workers in various industries and can easily improve productivity, saving time from going around temporarily to find tools or plugins.

Clean interface, efficiency first, excellent experience!
Compared with many similar tools, the UI of He3 Toolbox is relatively beautiful and simple enough to be comfortable, and it also provides very convenient shortcut keys to call out the interface anytime and anywhere, and supports “fuzzy search”, so you can quickly find the tools you need.

One click to call out He3 Toolbox
By default, press Alt + Space (Windows) or Option + Space (Mac) to immediately bring up the He3 Toolbox. Press Ctrl+K (Win) or ⌘+K (Mac) for a quick search. (All shortcuts can be changed in the settings)

Convenient fuzzy search + efficient preview of results
Even though the categories are clear, it is not easy to find what you need among hundreds of tools. he3 Toolbox provides a very useful and smart “fuzzy search” function, you only need to enter some keywords, it will intelligently list the relevant gadgets to help you solve the problem as fast as possible.

In addition, many tools also provide a search list “preview results” function, such as query IP address, view the current timestamp, color generator and other tools, it will be displayed directly in the search list, you do not even have to open the tool to see the results directly.

Smart clipboard recognition + auto-fill
One of the highlights of He3 is that it intelligently recognizes the contents of the clipboard. For example, when you copy a BASE64 encoded string and then open the “BASE64 decoding” tool, it will automatically read the contents of the clipboard and fill in the decoding for you; when you copy a string of JSON code, open He3 and it will automatically recommend some JSON related tools and so on.

Customize home page, drag and drop to adjust sorting, favorite
Because of the large number of tools included, He3 also provides users with a “personalized home page” that shows the most recently used, most frequently used, and favorite tools, making it easier for you to find them more quickly to use.
