GitHub Copilot vs Tabnine: Key Differences

GitHub Copilot and Tabnine are two popular AI-powered code completion tools that aim to enhance developers' productivity. Both tools leverage powerful AI models to suggest relevant code snippets while typing, reducing the time spent on repetitive tasks. However, they differ in certain aspects, making them suitable for varying development scenarios.

GitHub Copilot is trained on public GitHub repositories, while Tabnine uses a proprietary large language model trained on a curated selection of high-quality public code repositories. In terms of privacy and security, GitHub Copilot uses OpenAI's secure cloud-based solution, while Tabnine offers both cloud-based and on-premises solutions for enterprise environments.

GitHub Copilot supports a wide range of programming languages, while Tabnine has a focus on popular languages like Python, JavaScript, TypeScript, Ruby, Go, C, and C++. Pricing-wise, GitHub Copilot offers a free trial and then charges per user per month, while Tabnine has a free version and a paid version with additional features. Both tools provide integrations with various IDEs, enhancing the development experience. The best choice between GitHub Copilot and Tabnine depends on the specific requirements and preferences of the developer or organization.


Tabnine and GitHub Copilot are both AI-powered code completion tools designed to enhance the efficiency of coding. They leverage advanced AI models to offer real-time suggestions and minimize the likelihood of errors. GitHub Copilot is primarily trained on a vast corpus of public GitHub repositories, empowering it with a comprehensive understanding of code patterns and a broad language reach.

In contrast, Tabnine utilizes a large language model (LLM) trained on a curated selection of high-quality public code repositories. This focused training allows Tabnine to generate more contextually relevant suggestions and ensure the safety and security of its outputs. Additionally, Tabnine offers a unique feature: a local AI model that enables offline use, enhancing its versatility and appeal in specific use cases.

Training Data

The training data for Tabnine's large language model (LLM) is a key differentiator. Unlike GitHub Copilot, which trains on public GitHub repositories using OpenAI's Codex model, Tabnine uses a proprietary LLM trained on a carefully selected dataset of code repositories. This dataset is vetted to ensure high quality, robustness, security, and compliance with open-source licensing standards. This results in Tabnine generating safer, more suitable output for enterprise environments. Additionally, Tabnine offers a local AI model, allowing you to use it offline, providing greater control over usage and data privacy, especially for sensitive use cases within your proprietary code repositories.

Privacy and Security

Tabnine and GitHub Copilot employ robust security measures to protect user data. GitHub Copilot leverages GitHub's secure cloud infrastructure, while Tabnine offers both cloud-based and on-premises solutions. Both tools prioritize data privacy and adhere to industry-standard security practices.

Conversely, Tabnine's proprietary LLM undergoes rigorous training on vetted, high-quality code repositories, ensuring that its output meets stringent security requirements. This vetting process involves selecting code repositories with proven quality and security standards. The use of permissive open-source licenses further enhances the security of Tabnine's output, making it suitable for enterprise environments.

Language Support

Tabnine stands out with its extensive language support, catering to a wide range of developers. Unlike GitHub Copilot, which is primarily tailored to GitHub repositories, Tabnine's capabilities extend beyond the GitHub ecosystem. It supports an impressive array of programming languages and frameworks, including Angular, C, C++, Go, HTML/CSS, Java, JavaScript, Kotlin, Node.js, Perl, PHP, Python, React, Ruby, Rust, and Swift. This versatility makes Tabnine an indispensable tool for developers working with diverse codebases.

Test Code Quality

Tabnine excels in providing context-aware code suggestions tailored to the organization's best practices. Its proprietary LLM integrates seamlessly with visual Studio Code, IntelliJ IDEA, Sublime, Atom, and other popular IDEs.

GitHub Copilot, on the other hand, shines in its deep understanding of code patterns, thanks to its extensive training on public GitHub repositories. With its tight integration with GitHub, Copilot offers broad language support and is an ideal choice for developers working primarily with GitHub repositories. By leveraging the power of AI, both Tabnine and GitHub Copilot empower developers to write better code, making them valuable tools for software development teams.


GitHub Copilot and Tabnine both have pros and cons respectively. Which is better for your coding journey does depend on your needs and resources. Hopefully it’s helpful and see you next time.
