Devgrex vs Google Antigravity IDE

Devgrex is an AI-native development environment that combines an editor, autonomous agents, and model routing. Its Tab model offers context-aware multiline completions, partial acceptance, and ghost-text previews, with sub-100ms latency for local models. Agents can edit several files, run terminal commands in a sandbox, find and fix errors, and manage Git operations. Cloud Agents run on a cloud VM and can create GitHub or GitLab repositories, push branches, and open pull requests. Developers can use managed models from Anthropic, OpenAI, Google, and Moonshot, bring their own provider keys, or connect local models through Ollama and compatible servers. The environment also provides semantic codebase indexing and search, MCP connections to external tools, and compatibility with VS Code extensions, themes, keybindings, and settings. Privacy modes include local completions and offline operation, with automatic redaction before cloud requests. Its free plan includes local completions, agent chat, and offline mode. Devgrex was founded in 2025 and is based in Tallinn, Estonia.

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.
