AI Tools You Can Use in Visual Studio Code Besides GitHub Copilot

This article was originally published on freeCodeCamp, a popular developer learning platform

AI tools have become quite popular recently. Developers use these tools to help generate ideas, create simple code examples, and so on.

In 2023, ChatGPT and other Large Language Models found their way into many of our toolkits. And we can use them to be more productive and save time on repetitive tasks.

In this article, you’ll discover other helpful tools besides GitHub Copilot.

Before we discuss alternatives, let’s go over what GitHub Copilot is and what it does.

What is GitHub Copilot?

GitHub Copilot helps developers write code more quickly and efficiently. It’s a tool developed by GitHub and OpenAI that employs a strong AI and Codex.

GitHub Copilot works with a variety of code editors, including Visual Studio Code, NeoVim, and JetBrains.

GitHub Copilot uses machine learning. It doesn’t autocomplete – it suggests entire code snippets as you work in your text editor. It can also help you debug and refactor old code. The goal is to improve coding efficiency, decrease time spent on repetitive tasks, and increase productivity.

But GitHub Copilot has a downside: after the trial period, it costs $10 per month, which some users may consider too high.

So now let’s look at some alternatives which are free to use.

Snyk (DeepCode)

Synk, formerly known as DeepCode, is a tool that helps you keep your code safe. It works directly with your project file or repository, making it simple for teams to find and fix any security issues in their code, dependencies, containers, and infrastructure.

Synk (DeepCode) Homepage
Synk(DeepCode) Homepage

Use Cases

  • Ideal for early-stage security reviews.
  • Effective bug detection and resolution.

Features of Snyk

  • Scans your code early in development to help it pass security reviews. This helps avoid costly fixes later in the development cycle.
  • Scans for vulnerabilities and presents results with security issues.
  • Finds possible bugs in your code, helping you catch and fix issues early.
  • Suggests how to make your code run better.
  • Gets smarter by learning from different code examples. It gives better suggestions over time using algorithms.

Limitations of Synk

While Snyk is powerful too, it has a couple of limitations as well. First, it examines whole codebases, which could demand significant computing power, affecting the performance.

To help mitigate this issue, you can break down large codebases into smaller, manageable modules.

Also, there might be a bit of a learning curve for developers to understand how to get the most out of the tool.

But your team can offer training sessions or documentation to help you and other developers better understand how to use Synk effectively. Also, encourage your team to provide support resources, such as forums or documentation, to address common issues and questions.


Using Synk in Visual Studio Code for individual code security testing is entirely free. This allows for checking your code’s security before deploying it to production.

To collaborate within a team or for business purposes, upgrading the plan is necessary. You can find more information about the pricing plan here.

How to set up Snyk in Visual Studio Code

To set up Snyk, select the “View” option in your text to reveal a dropdown menu.

Select the “view” option in the editor

Then click on the “Extensions” option in that dropdown, and it will take you to the Visual Studio Code Marketplace.

In the marketplace,  type “Synk Security” and hit enter, then go ahead and install it.


How to authenticate in Snyk

After you’ve installed Snyk, you’ll need to authenticate.

Click on the Synk icon in your editor. This will take you to the authentication page.

Click on the button to authenticate and connect. Once you’re authenticated, go back to your editor. That’s it!

After completing this step, you can now use Snyk to examine, understand, and analyze your code before sending it in for production.

Example use case

To scan for possible vulnerabilities in the project file, just click on the sync icon on the left panel. This will analyze the code and highlight any potential issues that need attention.

If you take a closer look, you’ll see some letters indicating how vulnerable codes are.

  • “H” means it’s really high and needs fixing ASAP.
  • “M” means it’s at the maximum vulnerability level.
  • “L” means it’s at a low vulnerability level.

If you click on a vulnerability, you’ll get suggestions on how to fix it, which are displayed on the right side of the editor.

Use Cases for Cody AI

  • Facilitating creativity in tasks and brainstorming.
  • Resolving common issues with digital tools.
  • Strengthening teamwork through quick information sharing.

Features of CodyAI

  • Provides immediate responses to inquiries.
  • Allows you to upload various data types to build a customized knowledge base.
  • Cody’s responses all have adequate source citations.
  • Can help with email authoring, document translation, and marketing material generation.
  • Assists teams in using digital technologies to diagnose and resolve problems.
  • Based on previous encounters and contextual history, it makes suggestions and thoughts.

Limitations of Cody AI

As with any tool, there are limitations. First of all, the search capability of the AI isn’t as powerful. It analyzes user queries using available information. As a result, the AI may give answers that lack your desired depth or specificity at times.

Also, Cody AI Bots can’t do math or handle tables well. This means the AI might not give accurate answers when dealing with numbers or complex data.

Lastly, Cody AI Bots can’t understand pictures, diagrams, or anything visual in documents. It only uses text to come up with responses, so it’s not great at dealing with visual elements.

To help mitigate these issues, make sure you’re as clear and specific as possible when formulating your queries to help Cody better understand your intentions.

You can also break down complex questions into simpler components to improve the chances of accurate responses.


Installing Cody in your integrated development environment is free for personal use. However, for professionals or businesses looking to leverage Cody’s capabilities, an upgrade is required.

How to set up Cody in Visual Studio Code

First, select the “View” option in your text editor to reveal a dropdown menu as shown above.

Click “Extensions”, and it will take you to the Visual Studio Code Marketplace.

In the marketplace, type “Cody” and hit enter, then go ahead and install it.

Installing Cody AI
Cody Plugin

Now that the installation is complete, you can begin utilizing Cody in your editor.

Use cases

  • Speeding up Software Development: Facilitates faster and more efficient code writing.
  • Ensuring Code Consistency: Maintains a consistent coding style among different team members.

Features of Tabnine

  • Learns from the code you type and adjusts its suggestions to match your coding style.
  • Cares about your privacy. It only learns from open-source and permissive code, so you always own your code.

  • Makes coding easier by giving smart suggestions, and helping developers save time.
  • It works well with popular code editors like Visual Studio code. Developers can use it in their coding environments.

Limitations of Tabnine

Tabnine learns from how you code over time, so it might take a little time to match your coding style. It helps if you actively use the tool and provide consistent input to help it learn your coding style faster.

Tabnine also suggests code, but it doesn’t create entire sections. While this may seem like a limitation, it’s actually best for code quality.

Finally, it might suggest code that is not quite right. Developers should double-check the suggestions for accuracy. To help Tabnine suggest better code, you can regularly review and accept/reject suggestions to fine-tune its understanding of your preferences.

You should also always double-check the suggested code for correctness and adherence to coding standards before finalizing it.


Installation comes at no monthly cost, making it free. However, for larger organizations, it’s recommended to consider upgrading. Upgraded plans for larger organizations provide unlimited user access while prioritizing security and privacy.

How to set up Tabnine in Visual Studio Code

To begin, select the “View” option in your text editor to reveal a dropdown menu as shown above.

Click “Extensions” and it will take you to the Visual Studio Code Marketplace.

In the marketplace, type “Tabnine” and hit enter, then go ahead and install it.
