Devin vs Google Antigravity (2026)
Updated March 9, 2026
Overview
Devin by Cognition is the first fully autonomous AI software engineer. It can plan, write code, debug, deploy, and handle entire development tasks from start to finish using its own code editor, terminal, and browser. Devin works alongside human engineers on real-world codebases, handling tasks like bug fixes, feature implementations, and codebase migrations with minimal human intervention.
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.
- Fully autonomous software engineer
- Plans, codes, tests, and deploys
- Slack and IDE integration
- Parallel task execution
- Full development environment access
- 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
- Dramatically reduced pricing makes AI coding accessible at USD 20/month
- Strong performance on routine tasks—bug fixes, tests, and glue code
- Autonomous operation through Slack reduces context switching
- Proven ROI with companies like Nubank reporting 20x cost savings
Cons
- Completes only 15 percent of complex tasks without human help
- Gets stuck in technical dead-ends requiring intervention
- Cannot handle integration conflicts or unclear decision points
- Tasks take much longer than expected—days instead of hours for straightforward work
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
