The most important GitHub Copilot alternatives compared

GitHub Copilot was launched as a technical preview in June 2021 and has been generally available as an AI code generator since June 2022. It was developed to provide code completion suggestions directly in IDEs such as Visual Studio Code or JetBrains editors and to support programming tasks. In addition to autocomplete and chat, Copilot now also offers agentic functions such as Agent Mode in IDEs and a coding agent for pull request workflows. Nonetheless, there are now many AI websites, AI editors and coding agents that can be a useful GitHub Copilot alternative depending on the use case – whether for more general tasks, different workflows or varying requirements for data protection and functionality.

All details are correct as of June 2026.

Claude Code

Claude Code is an AI-powered coding assistant from Anthropic that has been publicly available since May 2025. Unlike classic autocomplete tools or a simple GitHub Copilot alternative, Claude Code is more agentic. The tool can analyse codebases, edit files, execute terminal commands, run tests and carry out development tasks across multiple files. Claude Code is therefore particularly suitable for developers who want to handle more complex tasks such as bug fixes, refactoring, implementing features or code reviews directly in the project context, and who are looking for a powerful alternative to GitHub Copilot.

It can be used in the terminal, in IDEs such as VS Code and JetBrains, as well as in other Claude environments, and is particularly interesting when you want an AI tool or a strong GitHub Copilot alternative not just to suggest individual lines of code, but to actively work on larger tasks in the repository as an alternative to GitHub Copilot.

Advantages Disadvantages
Strong focus on agentic coding workflows and complex tasks Less of a classic autocomplete tool than Copilot
Can analyse codebases, modify files and run tests Requires careful review of the proposed changes
Well suited for refactoring, bug fixes and larger project tasks Usage and feature set depend on Claude access and environment

ChatGPT / Codex

ChatGPT from OpenAI has been available since November 2022 and has become one of the world’s best-known AI assistants. With access to powerful models such as GPT-4 and later versions, ChatGPT can generate text, write and explain code, solve problems and support conversational research, making it a flexible GitHub Copilot alternative for a wide range of coding tasks.

Its coding agent can analyse codebases, edit files, run commands and tests, fix bugs, refactor code and help implement new features. This makes it a practical option for teams that need broader development support beyond code completion alone.

Advantages Disadvantages
Very versatile for text, code, analysis and research Data protection and data processing can be critical depending on how it is used
Strong performance on complex tasks and logical reasoning ChatGPT itself is not a classic IDE autocomplete tool
Large community and many integrations available Usage limits and range of features depend on the package

Gemini Code Assist

Gemini Code Assist is Google’s AI-powered coding assistant and therefore the more suitable GitHub Copilot alternative than the general Gemini chat product. While Gemini is mainly used as a versatile AI assistant for text, research, analysis and simple programming questions, Gemini Code Assist is specifically geared towards development workflows. The tool supports developers in VS Code, JetBrains IDEs and Android Studio with code completion, code generation, unit tests, debugging, documentation and context-related questions about their own project, and is often used as an alternative to GitHub Copilot in everyday coding.

Compared with GitHub Copilot, Gemini Code Assist is particularly strong for teams already working heavily in the Google ecosystem, for example with Google Cloud, Firebase, BigQuery or Android Studio. The enterprise version can also be tailored to private code repositories so that suggestions are more closely aligned with internal libraries, APIs and coding standards, making it a compelling GitHub Copilot alternative for many organisations.

Advantages Disadvantages
Support for VS Code, JetBrains IDEs and Android Studio Usage is closely tied to the Google ecosystem
Enterprise version can tailor suggestions more closely based on private code repositories Data protection aspects can be critical for some companies
Helps with code completion, code generation, tests, debugging and documentation Less flexible outside Google-centred workflows

Tabnine

Tabnine is an AI-powered code assistant that has been available since 2018. The company behind today’s Tabnine was founded in 2013 and was originally known as Codota. At the end of 2019, Codota acquired Tabnine and initially ran both products in parallel, before Codota was continued under the name Tabnine in May 2021. The assistant offers intelligent code completions and support for many IDEs such as VS Code or JetBrains products. Most users rely on Tabnine to get fast, context-aware and secure code suggestions without necessarily having to send data to the cloud. Tabnine offers strong data protection options as well as on-prem and air-gapped deployments.

Compared with GitHub Copilot, Tabnine is characterised by its stronger focus on data protection, local control and performance on simple autocomplete tasks, while Copilot generally offers more extensive natural-language-to-code generation and deeper integration into GitHub workflows instead.

Advantages Disadvantages
Very fast and precise code completion Less strong when it comes to complex architecture or design tasks
Support for local models and strong data protection Focus more on autocomplete than on explanations
Broad IDE support (VS Code, JetBrains) Advanced features require a paid package

Devin (formerly Windsurf)

Devin Desktop (formerly Windsurf) is an AI-powered code editor and combines classic code completion with AI chat, project context and agentic functions directly in the software. This allows Devin Desktop not only to suggest individual lines of code, but also to support larger tasks within a codebase.

This GitHub Copilot alternative stands out for its close integration of the editor, AI chat and project context. It is particularly suitable for developers who want an AI-centred development environment rather than an additional plugin for their existing integrated development environment (IDE). Devin offers a free entry-level package, while key features and higher usage limits are reserved for paid packages.

Advantages Disadvantages
AI-native editor with deep project context Less deeply integrated into DevOps and GitHub workflows
Good support for many programming languages Free package with limited agent quotas and restricted model selection
Combination of autocomplete and AI chat For very large projects, performance, context limits and costs can become a factor

Kiro (formerly Amazon Q Developer)

Kiro is AWS’s from-the-ground-up agentic, spec-driven development environment. Instead of relying on classic plugin-based autocomplete, Kiro uses structured specifications, automated hooks and sub-agents for multi-step development tasks and is closely tied to the AWS ecosystem. This makes the tool particularly suitable for developers working with AWS services and cloud infrastructure, for example for serverless functions, API integrations or cloud workloads.

Kiro is replacing Amazon Q Developer. New registrations for Q Developer have been unavailable since 15 May 2026, and support is due to end on 30 April 2027. Developers choosing a tool now should therefore consider Kiro instead. Kiro remains primarily focused on AWS-based development, whereas GitHub Copilot supports a broader range of coding environments and use cases.

Advantages Disadvantages
Modern, agentic, spec-driven approach with up-to-date coding models Less versatile outside the AWS stack
Excellent AWS integration plus security and best-practice guidance Migration from Q Developer required
Structured specifications, hooks and sub-agents for complex tasks General code generation weaker than with Copilot

Sourcegraph Cody

Sourcegraph Cody is an AI code assistant offered by Sourcegraph which, since its launch, has established itself as a cross-repository assistant for development teams. Cody uses AI to provide not only inline completions but also code navigation, intelligent search, refactoring suggestions and documentation generation. Users particularly value Cody in a team context when it comes to understanding large codebases or maintaining consistent coding standards.

With Cody, the focus is less on simple autocomplete suggestions and more on deep code-understanding features and advanced assistance, especially in enterprise environments with complex repositories.

Advantages Disadvantages
Strong understanding of large codebases Often oversized for small projects
Very good code search and context analysis Greater complexity and longer onboarding time
Particularly suitable for team and enterprise setups Resource-intensive with large repositories

Cursor

Cursor is an AI-powered code editor built around an AI-first development experience. Rather than functioning solely as a plugin for an existing integrated development environment (IDE), it combines AI-powered code completion, chat and specialised editing commands directly within the editor. Cursor is particularly suited to developers who are willing to switch to a new development environment in exchange for deeply integrated AI support, including codebase navigation, inline edits and multi-file changes. Compared with GitHub Copilot, Cursor is therefore less of an add-on for an existing IDE and more of a complete AI-focused code editor.

Advantages Disadvantages
AI-first editor with deep project context Steeper learning curve than classic IDE plugins
Well suited for refactoring and cross-project tasks Fewer integrations than established IDEs
Close integration of editor and AI features Smaller community than GitHub Copilot

Cline

Cline evolved from the former Claude-Dev project and is now a model-agnostic, open-source coding agent. Unlike traditional autocomplete tools, Cline is designed for more complex agentic development tasks. It can analyse project files, write and edit code, run terminal commands, use browser tools and present each proposed action for approval. This makes it particularly useful for fixing bugs, refactoring code, implementing features and making coordinated changes across multiple files.

One of Cline’s main advantages is its flexibility. It supports a range of AI models and providers, so developers are not tied to a single model ecosystem. However, its ability to make extensive changes also means that proposed file edits and terminal commands need to be reviewed carefully.

Advantages Disadvantages
Strong focus on agentic coding workflows and complex tasks Less of a classic autocomplete tool than Copilot
Can analyse codebases, modify files and run tests Requires careful review of the proposed changes
Well suited for refactoring, bug fixes and larger project tasks No own model – API costs when using external providers are variable and potentially high

Aider

Aider is an open-source tool for AI-supported pair programming in the terminal. It works directly with local Git repositories and can analyse existing codebases, edit files, store changes as commits and, where required, include tests or linting processes. Aider is particularly suitable for developers who prefer to stay in their usual development environment but want to carry out more complex coding tasks such as bug fixes, refactorings or feature implementations with AI support.

One advantage is the flexible choice of models. Aider can be connected to various AI models and providers, including local models. At the same time, the tool is more suitable for technically experienced users, as installation, API integration and working in the terminal require more personal responsibility than with a classic IDE plugin or a more straightforward GitHub Copilot alternative.

Advantages Disadvantages
Works directly in local Git repositories More suitable for technically experienced users
Flexible choice of models, including different providers or local models Setup and API integration require more personal responsibility
Can edit files, commit changes and include tests Terminal-based workflow is less beginner-friendly than IDE plugins

JetBrains AI Assistant / Junie

JetBrains AI Assistant is an AI-powered coding assistant for JetBrains integrated development environments (IDEs), including IntelliJ IDEA, PyCharm, WebStorm, PhpStorm, Rider and GoLand. It is built directly into the development environment and can help developers generate and explain code, refactor existing code, create unit tests and documentation, and draft commit messages and pull request summaries. It also provides context-aware chat, inline assistance and agentic features for multi-step development tasks.

JetBrains AI Assistant is complemented by Junie, JetBrains’ AI coding agent. Junie is designed for more complex tasks and can plan work, analyse project files, write and edit code, run terminal commands and tests, and make coordinated changes across multiple files.

GitHub Copilot supports a broader range of editors and GitHub workflows, while JetBrains AI Assistant stands out for its close integration with JetBrains IDE features, project context and established development workflows. However, it is less suitable for teams that mainly work with VS Code or other development environments.

Advantages Disadvantages
Very tight integration into JetBrains IDEs Less relevant for teams outside the JetBrains ecosystem
Supports code generation, refactoring, tests, documentation and commit messages Range of functions depends on IDE, model access and subscription
Junie can plan and execute multi-step coding tasks Not as usable across different editors as a typical GitHub Copilot alternative
