17 Free Tools to Learn the Basics of Coding
These 15 tools are great resources for anyone looking to learn to code on a budget.
Table of Contents
As a new entrepreneur or startup founder, you may not have the budget to hire web or software developers to create and maintain your business’s website, app and other technical aspects of your business. Luckily, there are free tools that can help you learn coding so you can take your computer programming into your own hands. And while basic mathematical skills help, you don’t have to be a technology whiz to learn coding to benefit your business.

The benefits of learning coding
Here are a few ways coding knowledge can improve your business.
Provides data insights
Today’s businesses use desktop and mobile applications for accounting, marketing, appointment booking, sales management, human resources, payroll and more. The problem is that few of these apps talk to each other. They contain valuable business data, but you never see it all in one place. With coding, data analysis can be integrated into your software, from platform to platform, so you can collect all of your important data in one place to make informed decisions.
Saves time and money
Having the ability to code (or use no-code platforms) lets you integrate your apps so they work together, thereby saving you and your staff time and money and streamlining the customer experience. As a business owner with coding knowledge, you’ll have a new way to contribute to your company, as well as better problem-solving skills to fix internal issues as they arise without needing to hire a freelance developer or another employee.
Enhances decision-making
Even with a basic understanding of coding and the underpinnings of your websites and apps, you will have an improved understanding of the data and technology your enterprise relies on. This knowledge gives you an edge in the modern business world and a leg up when making important business decisions about your tech products.
No-code development sites
If you’re not interested in doing the coding yourself, check out the growing number of “no-code” development sites. You can add 360-degree views of your products with Scapic, create workflows and automate processes with Parabola, build mobile apps with Bubble, and get spreadsheets and databases to talk to each other with Airtable. You don’t have to learn a line of code to use any of these tools, yet your company will benefit.
No-code and low-code website development sites such as Wix, Webflow and Squarespace allow you to create advanced design layouts and interactions without any need for programming skills. See our Wix review for more information, and learn more in our overview of the best website builders.
