AI IDE Comparison 2026: Antigravity vs Cursor vs Kiro vs Devin
A June 29, 2026 update compares four AI-powered integrated development environments (IDEs)—Antigravity, Cursor, Kiro, and Devin Desktop—and summarizes major product launches, rebrands, pricing shifts and platform availability during the first half of 2026. Notable changes include Google’s Antigravity 2.0 release, AWS Kiro reaching general availability and new tiers, Cognition rebranding Windsurf to Devin Desktop with an agent replacement and end-of-life schedule, and converging entry-level pricing and credit/quota billing across the category. The author highlights proprietary model differentiation (e.g., Cursor’s Composer 2.5, Devin’s SWE-1.6, Google’s Gemini 3.5) and mentions growing adoption of standards (MCP, ACP, AGENTS.md) making agent workflows more portable.
Major platform product updates and availability (Google Antigravity 2.0, AWS Kiro GA and new tiers) materially affect the LLM/IDE ecosystem, developer workflows, pricing models, and integration choices that can indirectly impact tooling and platform integrations across tech industries.

Choosing AI Coding Tools in 2026: Copilot vs Others
This article compares five AI-assisted developer tools in 2026 — GitHub Copilot, Cursor, Anthropic's Claude Code, AWS's Kiro, and Google Antigravity — highlighting differences in workflow focus, agent capabilities, and pricing. Copilot (GitHub/Microsoft) remains strong for inline completion and deep GitHub integration and now offers Agent Mode and a cloud-based Copilot Coding Agent that can run tasks via GitHub Actions. Cursor and Antigravity are editor-focused VSCode forks with multi-agent/background capabilities; Cursor emphasizes an editor-native Composer and Background Agents, while Antigravity (launched Nov 2025 with Gemini 3) centers on an Agent-First Manager Surface and multi-model support. Claude Code is a terminal-first tool with Hooks, Skills, MCP Server and Channels for automation. Kiro (AWS/Bedrock) differentiates itself with Spec-Driven Development and Agent Hooks. The author also provides a March 2026 pricing snapshot and scenario-based recommendations for different workflows.
Google Antigravity 2.0: Agent Harness Replaces IDE
Google announced Antigravity 2.0 at I/O 2026, shifting its developer strategy from an IDE-centric AI assistant to a single shared "agent harness" accessible via four surfaces: a desktop agent-first app, a rebuilt Antigravity CLI (in Go), an Antigravity SDK, and the Antigravity IDE. The harness centralizes agent execution so behavior improvements propagate across all surfaces. Key features include parallel agent orchestration, dynamic subagents, scheduled background tasks, and Managed Agents in the Gemini API that run stateful, resumable agents inside isolated Linux environments (pay-per-run pricing). The SDK enables on‑prem deployment for regulated environments. Antigravity is optimized for Google models (Gemini 3 Pro / 3.5 Flash) but supports Anthropic’s Claude Sonnet 4.5 and OpenAI’s GPT-OSS. Gemini CLI and Gemini Code Assist IDE extensions will stop serving requests on June 18, 2026. Google frames this as an architectural move to make Gemini the platform plumbing beneath third-party products.
Agentic IDEs Compared: Claude Code, Cursor, Windsurf
A 2026 hands-on comparison of three agentic IDEs — Claude Code, Cursor, and Windsurf — finds no single winner. Claude Code excels at terminal-native, autonomous multi-file refactors using MCP (Model Context Protocol) servers and scripting/CI integration. Cursor, a VSCode fork, leads on real-time autocomplete and inline edits but struggles with large cross-file agentic tasks. Windsurf adds governance (approval gates, audit logs) for compliance-focused teams, trading speed for auditability. Benchmarks show Claude Code completed 87% of a multi-file TypeScript refactor autonomously, Cursor 34%, and Windsurf 41%; all tools still required human review for edge cases.
