Google's agent-first development platform for building and shipping software with AI agents
A desktop app, a full agentic IDE, a terminal-first CLI, editor extensions, and an SDK let you run Antigravity agents wherever you already work.
Group conversations into Projects and run several local agents at the same time, across multiple workspaces, rather than one at a time.
Agents produce designed artifacts such as plans and comprehensive verification tests so output can be reviewed, not just accepted.
Runs on Google's Gemini model line, including releases such as Gemini 4 Carbon, Gemini 4 Argon, and Gemini 3.8 Flash.

Revive legacy WPF and Silverlight apps as modern .NET web apps
Recompile existing Silverlight or WPF C#, VB and F# code into a WebAssembly app that runs in any modern browser, avoiding a costly rewrite.
OpenSilver 3.3 adds an AI-assisted drag-and-drop UI designer for building and editing XAML screens faster.
Host Blazor components directly inside XAML applications and integrate with MAUI Hybrid, plus mix in React or Angular where useful.
Keeps support for RIA Services, LightSwitch and common third-party controls so established business apps keep working.

#1Describe your idea in chat and Lovable turns it into a working app or website

Offers a more mature polished AI-native coding experience, but lacks Google's specific native multi-agent command center ecosystem.

Build working apps, websites, and AI agents by describing them

Enables rapid full-stack app building and deployment entirely in the cloud, but offers less granular local agentic control.
Deeply reads entire codebases to execute complex multi-file tasks, though integrated as an IDE plugin rather than standalone suite.
Delivers robust spec-driven engineering and autonomous verification workflows, though configured differently than Google's developer platform.
Cognition's autonomous software engineer that ships real pull requests
Free / Open-sourceOpen-source development environment running multiple CLI coding agents in isolated git worktrees, but requires manual setup.

Provides a seamless AI-driven IDE workflow with strong multi-file editing, but offers less specialized multi-agent orchestration control.
