Best API Documentation Tools

In software development, documentation is like the broccoli of the meal — not always the most exciting part, but it’s essential for a healthy project.

Like how broccoli can be cooked in many different ways to make it more palatable, many tools are available to make the documentation less of a chore and more of a delight.

This article’ll explore the benefits of using these tools and how they can turn your documentation from a bland, forgettable side dish into a mouth-watering main course.

So grab your forks, and let’s dig in!

1. Docusaurus

This is developed by Meta. You can create really nice-looking documentation websites super fast.

It can also be used to build static websites. You can take a look here for some inspiration.

To create a website, Just run the following command.

npx create-docusaurus@latest my-website classic

It supports markdown files. You can write both blogs and docs with this tool.

You can also customize the look and feel using the configuration options of Docusaurus

This is based on React. So if you are already familiar with ReactJS then, it will help a lot!

5. Redoc

Redocly is another OpenAPI documentation generator tool. It’s like Swagger but with a better interface (In my opinion).


You can provide an open API file, and it will auto-generate the documentation and provide you with some boilerplate code as well!


ReDoc Interactive Demo


  • It has a VS code extension

  • Tons of customization.

  • Direct integration with OpenAPI


  • It’s not completely free. It has paid versions as well.

In fact, it will add an example code snipped automatically! Also, it provides you a nice dashboard with statistics.

But it has both free and paid plans, So choose accordingly!




Documenting code may never be as fun as binge-watching your favorite TV show, but with the right tools, it can be almost as enjoyable as ordering a pizza.

So don’t let documentation be the Brussels sprouts of your software project — spice it up with some humor, creativity, and a good documentation tool.

Who knows, you may even discover that you have a hidden talent for technical writing. And if not, at least you’ll have some well-documented code and a satisfied appetite.

Happy coding, and bon appétit! I hope you learned something new today!
