Google Antigravity IDE vs Hyperlane

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.

Hyperlane is a free desktop IDE built on the VS Code engine for running coding agents in parallel. Each agent works in a separate Git worktree, and the product describes running four agents on four tasks at once. It supports a catalog of coding agents, any CLI-based agent and agents that speak ACP. The editor includes language server support, extensions, terminals, source control, multi-cursor editing, snippets and refactoring. An agent’s branch can be opened for pull request review alongside its checks, description, diff and thread. Other listed tools include project search, a three-way merge conflict editor, an HTTP client, design mode, Prettier formatting and Vitest support. VS Code settings, keybindings, themes and extensions carry over. Hyperlane says source files are processed locally and are not intentionally collected, stored or accessed by the maker; content sent to AI services goes directly to the chosen provider. Desktop telemetry may include usage, device, operating-system, error and crash data, designed to exclude source files. It is free to download for macOS, Windows and Linux.
