GitHub Copilot
GitHub Copilot dominates Reddit discussions across r/programming and r/webdev as industry-standard AI coding assistant powered by OpenAI Codex (GPT-3.5/4 architecture), delivering inline code suggestions directly in VS Code, JetBrains, Neovim, and Visual Studio with context awareness from current file and limited surrounding files—Reddit consensus establishes Copilot as most reliable autocomplete with strongest VS Code integration despite $10/month cost versus free alternatives. Developers consistently praise Copilot for "saving time on boilerplate code" and "autocomplete that reads your mind when it works," though Reddit users warn "be careful, Copilot can make you lazy—verify everything it suggests" due to occasional outdated patterns or subtle bugs requiring human review before accepting suggestions blindly.
