AI IDE Comparison 2026: Antigravity vs Cursor vs Kiro vs Devin Desktop

The AI IDE Landscape Has Shifted: A 2026 Comparison of Antigravity, Cursor, Kiro, and Devin Desktop.

The first half of 2026 has reshaped the AI IDE space more than any previous period. Major acquisitions, full product rebrands, and a category-wide shift from request-based to credit-based pricing have changed the calculus for developers choosing their tools.

I recently updated my comparison article on Devlycan to reflect these changes, and I'd like to share a brief summary of what's new.

What Changed in the First Half of 2026

March 19, 2026 — Windsurf retired its credit system in favor of daily and weekly quotas. Pro pricing moved from $15 to $20, and a new $200 Max tier was introduced.

May 7, 2026 — AWS Kiro reached general availability, officially replacing Amazon Q Developer as the spec-driven IDE in the AWS ecosystem.

May 19, 2026 — Google launched Antigravity 2.0 at I/O 2026 with a standalone desktop app, CLI, and SDK. The AI Ultra tier was reduced to $100/month.

June 2, 2026 — Cognition rebranded Windsurf to "Devin Desktop" via an over-the-air update. The Cascade agent was replaced by Devin Local, with Cascade reaching end-of-life on July 1.

June 17, 2026 — AWS introduced a Kiro Pro Max tier at $100/month and released a native iOS app at AWS Summit NYC.

Key Takeaways from the Comparison

• Entry-level pricing has converged at $20/month across all four tools, but what each plan delivers varies significantly.
• Every IDE now uses a credit or quota system, making real cost dependent on which AI model you choose to run.
• Proprietary models have become a differentiator — Cursor's Composer 2.5, Devin Desktop's SWE-1.6, and Google's Gemini 3.5 each optimize for different workloads.
• Open standards are quietly converging — MCP, ACP, and AGENTS.md adoption is making agents increasingly portable across editors.

Who Should Use Which Tool

• Cursor remains the most balanced choice for everyday coding productivity.
• Antigravity suits teams exploring multi-agent automation within the Google/Gemini ecosystem.
• Kiro fits AWS-centric teams that value spec-driven workflows and compliance traceability.
• Devin Desktop excels at large codebases, agent-heavy workflows, and regulated industries requiring HIPAA, FedRAMP, or ITAR compliance.
