GitLab Duo Code Suggestions vs Google Antigravity IDE

GitLab Duo Code Suggestions provides code completion and generation in supported editors. It can complete code blocks, help define function logic, generate tests, and suggest common patterns such as regular expressions. Supported editors include Visual Studio Code, GitLab Web IDE, Microsoft Visual Studio 2022, JetBrains IDEs, Neovim, and Eclipse; GitLab lists more than 14 supported languages, including C++, C#, Go, Java, JavaScript, Python, Rust, and TypeScript. The feature is available on the GitLab.com Free tier with GitLab Credits, and self-managed GitLab instances can use it through a secure connection to GitLab.com. GitLab says it does not train generative AI models and that private, non-public customer code stored in GitLab is not training data. Suggestions are scanned to help prevent sensitive information such as API keys or passwords from being shared. GitLab warns that high demand may degrade performance or cause unexpected downtime. GitLab Duo Pro is listed at $19 per user per month.

Google Antigravity IDE is an agentic development environment where software agents plan and execute tasks across an editor, terminal, and browser. Agent and Tab features include real-time code completion and helper suggestions, while asynchronous local agents can work in parallel across workspaces and codebases. Their deliverables can include Markdown plans, code diffs, architecture diagrams, images, and browser recordings; the browser agent can read dashboards, perform source-control actions, and test interfaces. Projects can use Git worktrees, scoped permissions and settings, and multiple folders. Agents are limited to project folders and request permission for terminal commands outside the sandbox on macOS and Linux, or for any terminal command on Windows. The standalone IDE supports macOS 12 or later, Windows 10 64-bit, and Linux meeting specified library minimums. Individuals have a free plan at free, with baseline Gemini access, unlimited Tab completions and Command requests, and basic weekly rate limits. Limits depend on plan and workload; enterprise customers are not supported for this IDE.
