How to Choose a Coding Agents Tool
Key criteria to evaluate when comparing Coding Agents solutions:
About GitHub Copilot
GitHub Copilot is the most widely deployed AI coding assistant in the world, integrated natively into VS Code, JetBrains, Visual Studio, GitHub.com, GitHub Mobile, and GitHub CLI. It provides inline code suggestions, Copilot Chat, agent mode (multi-step file edits), code review automation, and customer-tunable models for Enterprise customers.
As of 2026, Copilot ships in five tiers — Free, Pro ($10/mo), Pro+ ($39/mo), Business ($19/user/mo), and Enterprise ($39/user/mo, plus required GitHub Enterprise Cloud at $21/user/mo for $60 total). Microsoft's IP indemnification on Business and above is a major enterprise differentiator. Copilot Enterprise can index an organization's codebase for tailored suggestions and supports fine-tuned custom private models.
GitHub announced that all Copilot plans transition to usage-based billing on June 1, 2026 — every plan includes a monthly allotment of GitHub AI Credits, with code completions and Next Edit suggestions remaining unmetered. The shift moves Copilot closer to API-style pricing for power users and away from flat per-seat costs.
About Google Antigravity
Google Antigravity is Google's agentic development platform, announced alongside Gemini 3 in late 2025. Built as a modified VS Code fork, Antigravity combines a traditional AI-powered editor with a Manager View for orchestrating multiple autonomous agents working in parallel across workspaces. Agents can plan, execute, and verify complex tasks across editor, terminal, and browser environments. The platform achieved 76.2% on the SWE-bench Verified benchmark, demonstrating strong code generation capabilities. Antigravity supports Gemini 3 Pro, Deep Think, and Flash models, plus third-party models including Claude, making it flexible for developers who want to use different AI providers. Currently available in preview for personal Gmail accounts on Mac, Windows, and Linux, Antigravity is free during the preview phase but expected to introduce paid tiers. Google AI Pro subscribers ($20/month) and AI Ultra subscribers ($250/month) receive higher rate limits, with rate limits refreshing every 5 hours for Pro users.
