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.

Verify and clean email lists before you hit send
Every address is classified as Deliverable, Undeliverable, Risky or Unknown, so you know exactly why a contact should be kept, throttled or dropped.
Detects the address types that quietly wreck campaigns, including spam traps, role accounts, catch-all domains and disposable inboxes.
Upload a list in the client area and download a cleaned file in Excel XLSX, CSV or TXT while keeping your original row order.
Verify addresses in real time on signup or import with documented examples for Go, Java, PHP, Python and .NET.

#1
Offers a more mature polished AI-native coding experience, but lacks Google's specific native multi-agent command center ecosystem.

Enables rapid full-stack app building and deployment entirely in the cloud, but offers less granular local agentic control.
All-in-one customer platform for email, SMS, CRM, and automation
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.


AI-native cold email platform for scaling outbound without limits

Email marketing with AI send-time optimization to lift opens
Provides a seamless AI-driven IDE workflow with strong multi-file editing, but offers less specialized multi-agent orchestration control.

SpecialistAI-powered terminal and agentic software factory for development teams
