Google Antigravity

Google Antigravity is Google's latest AI-first agentic development platform (November 2025), enabling autonomous agents to build software end-to-end. Powered by Gemini 3 Pro (Google's most powerful model) plus optional Claude Sonnet 4.5 and GPT-OSS. Through JoinBareng's shared subscription, stable access without throttling starts at Rp 75,000/slot.

Who it's for:
✅ Developers exploring multi-agent coding workflows
✅ Solo founders wanting autonomous agents to build MVPs
✅ Early-stage teams needing parallel task execution (frontend + backend + tests)
✅ AI enthusiasts wanting to try Gemini 3 Pro without free-tier rate limits

Key benefits:
✅ Gemini 3 Pro (Google's most powerful model)
✅ Claude Sonnet 4.5 + GPT-OSS optional
✅ Multi-agent parallel execution
✅ Integrated browser + terminal in IDE
✅ Agent Manager view to supervise multiple agents
✅ Artifact-based workflow (Task List, Walkthrough, Screenshot)

Antigravity vs Cursor / Claude Code:
Cursor focuses on single-agent pair-programming. Claude Code excels at terminal / CLI workflows. Antigravity focuses on multi-agent supervised work — run 3-5 agents in parallel on different modules, then review artifacts. Ideal for large projects needing decomposition.

Access & onboarding:
Once the group forms, JoinBareng admins invite your email to the Antigravity workspace. Download from antigravity.google, log in, select workspace. Activation within 1-2 business days after slots fill.

Important! Group access via JoinBareng uses Antigravity's official workspace invitation feature. Each member logs in with their own Google account — credentials are not shared.
