Google Antigravity vs Tabnine (2026)
Updated March 10, 2026
Overview
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.
Tabnine is an AI code assistant focused on privacy and enterprise compliance. It offers code completions, chat, and code generation while keeping code private—models can run entirely on-premises or in a private cloud. Tabnine supports all major IDEs and programming languages, and differentiates with its zero data retention policy and SOC 2 Type II compliance, making it the go-to choice for regulated industries.
