What do you like best about GitHub Copilot?Contextual Autocomplete: It suggests entire blocks of code, functions, and tests by analyzing your current file and open tabs. Boilerplate Reduction: It handles repetitive tasks like writing unit tests, regex, or standard API calls, allowing you to focus on logic. Natural Language to Code: You can write a comment describing what you want (e.g., // function to validate email using regex), and it will generate the implementation. Multi-language Support: It works across dozens of languages including Python, JavaScript, TypeScript, Ruby, Go, and Java. IDE Integration: It lives directly inside popular editors like VS Code, JetBrains, and Neovim, so there is no need to switch windows. Review collected by and hosted on G2.com.What do you dislike about GitHub Copilot?1. Inaccuracy and "Hallucinations" Code Quality: It often suggests code that is inefficient, outdated, or uses libraries that don't actually exist (hallucinations). Bugs: It can generate syntactically correct code that contains subtle logical errors, requiring you to spend more time debugging than if you had written it yourself. 2. Context Limitations Large Projects: It sometimes "forgets" logic established earlier in a file or fails to understand the broader architecture of a complex project. Proprietary Logic: It struggles with custom frameworks or internal business logic that wasn't part of its public training data. 3. Privacy and Security Data Training: Many users are concerned about their code being sent to GitHub's servers to train future models. As of early 2026, some users have expressed frustration over "automatic opt-in" policies for data collection. Vulnerabilities: There is a risk that the AI might suggest patterns that include known security vulnerabilities (like SQL injection) if they were prevalent in its training set.
