Top 7 GitHub Copilot Alternatives


GitHub Copilot is probably the best tool to solve all your coding problems, but have you ever considered its alternatives?

In fact, using alternatives would be better for overcoming many shortcomings of GitHub Copilot.

Some great GitHub Copilot alternatives include Tabnine, Captain Stack, GPT-CC, Code Whisperer, CodeGeeX, and IntelliCode, which provide greater access to coding features.

Read on to discover more about GitHub Copilot and some of its worthy alternatives.

What Is GitHub Copilot And How Does It Work?

GitHub Copilot is a code generation tool developed by the collaboration of GitHub and OpenAI, which started in 2021.

It is designed to help developers write code more efficiently by providing intelligent suggestions and completing code snippets.

Copilot uses OpenAI’s GPT-3 architecture to generate responses, but the reactions are limited to coding activities, including;

  • Boilerplate Code: It helps generate templates, so coders need not start a project from scratch.
  • Debugging: it can detect coding errors and report them to the user with suggestions.
  • Writing Tests: It helps generate test cases and assertions for various functions.
  • Complete Code Snippets: It completes missing or incomplete codes based on the code’s context and your requirement.

If you are wondering, Copilot uses a machine learning model trained on a large corpus of open-source code to generate code snippets in various programming languages.

For now, it works as a plugin for Visual Studio Code (an integrated development environment) but as an independent tool.

Why Look For GitHub Copilot Alternatives?

Although quite helpful, GitHub Copilot is not free from shortcomings.

Here are a few reasons why you should consider GitHubCopilot alternatives.

Top 7 GitHub Copilot Alternatives

Here are a few popular recommendations for GitHub Copilot alternatives.

1. Tabine

Tabnine is an AI technology that assists with predicting and suggesting codes based on context and syntax.

Formerly known as Codota, it is among the first code-completing tools which complete code and enables training your private AI model.

Trained with a machine learning algorithm, it helps with a variety of tasks, including;

  • Whole line code completions
  • Full function code completions
  • Natural Language to code

Tabnine and Copilot use AI to suggest codes, so they are not significantly different.

However, Tabnine only uses open-source code with permissive licenses, which Copilot does not.

Here is how Tabnine fares to Copilot.

Tabnine offers both a free and a paid plan ($12 /mo).Copilot only offers a paid plan ($10 /mo and $100 /year).
It uses open-source code with permissive licenses and never trained with public model.It may copy from various online resources, including stackoverflow, posing copyright issues.
It offers self-hosting capabilities via VPC or on-premises deployment.It does not offer self-hosting feature but OpenAI server.
It may be limited in completing large chunk of codes or function.It comes quite handy in completing large chunks of code and even whole functions.

2. Captain Stack

Captain Stack is an open-source VSCode plugin that combines the features of both Copilot and Stack Overflow and provides relevant code suggestions.

Did you know GitHub was an inspiration behind the creation of Captain Stack?

However, Captain Stack uses Google to populate its knowledge base, unlike Copilot, which depends on a large data corpus. Captain Stack submits your query to Google, retrieves answers from Stack Overflow and Github Gist, and auto-completes them to provide an accurate response.

You can easily access the CaptainStack information on Visual Studio Marketplace to learn how to install and use it.

Here is how Captain Stack fares to Copilot.

Captain StackCopilot
Captain Stack is completely free for use.Copilot only offers a paid plan ($10 /mo and $100 /year).
It generates knowledge from Google and sites like Stack overflow, GitHub Gist.It generates knowledge from Stack overflow and GPT database.
It is quite updated than GPT’s knowledgebase.Copilot uses GPT-3.5 which is not yet updated.

3. GPT-Code-Clippy (GTP-CC)

GPT-Code-Clippy (GPT-CC) is an open-source version of GitHub Copilot based on GPT-3 architecture called GPT-Codex.

It was created by EleutherAI, a community-led organization focused on developing large-scale language models.

As an AI assistant tool, it provides code suggestions and completion and performs coding activities based on the data fine-tuned on publicly available code from GitHub.

GitHub Copilot alternatives
Although similar to Copilot, GPT-Code-Clippy was initially developed to help researchers study sizeable deep-learning models.

The code for AI Clippy is written in Python and is based on the Hugging Face Transformers library, which provides an easy-to-use interface for building and training language models.

Because it is trained on GPT-2 and Neo models, it has not been trained on billions of lines of public code and parameters like Copilot.

Here is how GPT-Code-Clippy (GPT-CC) and Copilot differ from each other;

GPT ClippyCopilot
It is completely free for use.Copilot only offers a paid plan ($10 /mo and $100 /year).
It uses the GPT-2 and Neo model, trained for text generation, sentiment analysis, and Q&A models.It uses GPT-3 architecture designed as an AI assistant for various tasks.
It is an open-source model that anyone can download and use via GitHub or use an a plugin for VSCode extension.It is only available as a plugin for VSCode extension.
The training scripts are based on the Flax Causal Language Modelling script accessible on Huggingface.The training script lies entirely on GPT architecture with no exclusive access to it.

4. IntelliCode

Intellicode is a set of AI-assisted development tools created as an experiment by Microsoft.

It aims to improve the productivity and efficiency of developers by providing relevant and accurate coding suggestions.

However, it is trained on selected GitHub projects and is available only as a Microsoft product for Visual Studio.

It applies machine learning algorithms to analyze existing codebases and provide autocomplete suggestions, code snippets, and intelligent code formatting options based on the code’s context.

The most attractive feature of IntelliCode is team completion, which proves beneficial for organizations with a Microsoft-based architecture to collaborate.

Here is how Intellicode differs from GitHub Copilot;

It is completely free for use.Copilot only offers a paid plan ($10 /mo and $100 /year).
It is a Microsoft tool that integrates with its own development tools like Visual Studio Code and Visual Studio.It is a standalone tool that integrates with Visual Studio Code and other code editors through plugins.
