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 analyze 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.

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 analyze 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.

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 toward 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 or­ga­ni­za­tions.

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 char­ac­ter­ized 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.

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-centered de­vel­op­ment en­vi­ron­ment rather than an ad­di­tion­al plugin for their existing in­te­grat­ed de­vel­op­ment en­vi­ron­ment (IDE). Devin offers a free entry-level plan, while key features and higher usage limits are reserved for paid plan.

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.

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.

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 spe­cial­ized 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.

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 analyze 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.

Aider

Aider is an open-source tool for AI-supported pair pro­gram­ming in the terminal. It works directly with local Git repos­i­to­ries and can analyze 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.

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, analyze 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.
