GitHub Copilot vs Google Antigravity (2026)
Updated April 29, 2026
Overview
GitHub Copilot is the most widely deployed AI coding assistant, integrated into VS Code, JetBrains, Visual Studio, and more. Five tiers: Free, Pro ($10/mo), Pro+ ($39/mo), Business ($19/user/mo), Enterprise ($39/user/mo). Moving to usage-based AI Credits billing on June 1, 2026.
Google Antigravity is Google's agentic development platform, with an agent-first IDE, a terminal CLI, and Antigravity 2.0 for running multiple coding agents in parallel.
Key features
Core capabilities each platform advertises.
- Inline suggestions and Next Edit across VS Code, JetBrains, Visual Studio, GitHub Mobile
- Agent mode for multi-step autonomous file edits
- Copilot Chat in IDE and on GitHub.com
- Code review automation in pull requests
- Enterprise: codebase indexing + fine-tuned private models
- Agent-first IDE with an agent manager and codebase-aware context
- Antigravity 2.0 for running multiple local agents in parallel
- Terminal CLI with background subagents
- Python SDK for prototyping custom agents
Strengths and tradeoffs
What each tool does well, and the limitations to keep in mind.
Pros
- Most broadly integrated AI coding assistant — works everywhere developers code
- Microsoft IP indemnification on Business+ tiers
- Strong enterprise security, SSO, and admin controls
- Codebase-wide indexing on Enterprise
- Mature, battle-tested at Fortune 500 scale
Cons
- Quality often trails purpose-built agents like Claude Code or Cursor
- Usage-based AI Credits (June 2026) make budgeting harder
- Enterprise total cost ($60/user/mo) is steep with required GitHub Enterprise Cloud
- Less aggressive on agentic / autonomous workflows than competitors
Pros
- Free individual plan with unlimited Tab completions and Command requests
- Works across an IDE, a terminal CLI, and a standalone agent manager
- Gemini models on every plan, with Claude Sonnet 5.5 and Opus 5.5 on paid plans
- Business plans include spend caps and centralized admin controls
Cons
- Rate limits are described by tier rather than published as specific numbers
- Claude models require Google AI Pro (non-trial) or higher
- Pro and Ultra are Google One bundles, so you pay for storage and other services too
- Model choice is limited to the models Google lists for each plan
What people are saying
Microsoft's commitment to defend customers against certain intellectual property claims related to Copilot output is a major reason we standardized on Business.
