The best no-code tools for beginners are the ones that you learn from and enable you to build something within a few hours at most. And don't worry about costs when you're starting out. Many no-code tools operate on a freemium model.
Here are two strategies for finding the right no-code tools to start your journey.
Strategy One: Build on what you already know
Start by looking at the tools you already use.
Already using Notion? Create a website with Notion and Super to hide the URL. Heavy Airtable user? Use Softr or Pory.io to turn a base into a website.
If you're active on social media, maybe now is the time to look at IFTTT or Zapier. Use these services to share your posts to other social platforms or create an archive. Another approach - Over the course of several days or a week, make a list of tedious manual tasks, like saving email attachments to Google Drive. With list in hand, search Zapier for services related to the tasks you wrote down. Start automating. You'll gain skills -- and save time that you can use for the second strategy for getting started with no-code.
Strategy Two: Start from Scratch
Make two lists.
List One: Tools that interest you
List Two: Ideas of what you would like to build
Now that you have your two lists, look to see which tools would enable you to make something -- not the whole thing -- related to what's on your idea list. Pick a no-code tool that appeals to you. Create an account. Watch or read a tutorial or two. Start building. Spend at most a few hours.
Whether you use one or both of these strategies, this experience will introduce you to concepts that will help you evaluate which tools are right for you moving forward.
Part of picking the best no-code tool is understanding how you think and process information. Until you start experimenting with tools, you're not going to know which no-code tools are the best ones for you. As you explore, you'll also come to understand what's possible and where there are limitations. This will be valuable information as you increase your skills and start building more complicated products and services.
