Setup and context
March 2026 has been a whirlwind month for the AI-assisted development world. We saw Antigravity ship v1.20.3 with meaningful quality-of-life improvements, the AI IDE market undergo major consolidation, and Google AI Studio transform into a full-stack vibe coding platform.
At Antigravity Lab, we published over 275 articles this month covering everything from getting started guides to advanced agent orchestration patterns. In this monthly recap, we'll walk through the biggest developments from March, share our most-read articles, and look ahead to what April has in store.
Major Updates and News from March
Antigravity v1.20.3 (March 5)
The most significant Antigravity release this month brought several welcome improvements.
AGENTS.md support: Agent configuration rules can now be read from AGENTS.md in addition to GEMINI.md. This is a great step toward standardization for teams that work across multiple AI IDEs.
Auto-continue enabled by default: The setting that previously required manual opt-in is now on by default, allowing agents to complete tasks without interrupting you with continuation prompts.
Faster conversation loading: Long conversation histories now load noticeably faster, improving the day-to-day experience.

# Expected output: Antigravity v1.20.3

AI IDE Market Shakeups
March was eventful across the entire AI IDE landscape.
Cursor crosses $2B ARR: Cursor reached $2 billion in annualized recurring revenue in Q1 2026, solidifying its lead in the AI IDE market. JetBrains support also shipped in March, expanding beyond the VS Code ecosystem. See our Antigravity vs Cursor comparison for a detailed breakdown.
GitHub Copilot adds Jira integration: You can now assign a GitHub issue directly to Copilot, and it will autonomously write code, create a pull request, and respond to review feedback. Our article on Copilot Coding Agent vs Antigravity covers how the two tools compare.
Windsurf acquired by Cognition: In a surprising move, Cognition (the makers of Devin) acquired Windsurf for $250 million — just after Google recruited Windsurf's founders for $2.4 billion. The AI IDE space continues to consolidate rapidly.
Google AI Studio Goes Full-Stack
Google AI Studio received a major overhaul in March, enabling developers to build production-ready applications directly from prompts.
- Firebase integration: Cloud Firestore and Firebase Authentication are now built in
- Next.js support: Joins React and Angular as an officially supported framework
- Secrets Manager: Securely manage API keys from the Settings tab without hardcoding credentials
Google Stitch Multi-Screen Generation
Google's design tool Stitch also leveled up with its March 19 update. It now generates up to five interconnected screens simultaneously, automatically maps user journeys, and exports production-ready code to seven frameworks.

Key Takeaways from March
A few trends crystallized over the course of this month.
Multi-agent is becoming table stakes: GitHub Copilot, Cursor, Windsurf, and Antigravity are all shipping multi-agent capabilities. Antigravity's declarative approach through AGENTS.md offers a unique angle — letting developers define agent behavior through configuration rather than code.
Vibe coding is going mainstream: With Google AI Studio now supporting full-stack app generation and Stitch enabling multi-screen prototyping, the gap between "describe what you want" and "get a working app" is shrinking rapidly.
Credit management is a new developer skill: As usage-based pricing becomes the norm across AI IDEs, knowing how to optimize your credit consumption is becoming an essential part of the developer toolkit.

What to Watch in April
Next Antigravity Update
A stable release following v1.20.3 is expected in April. Watch for official Browser Sub-Agent support and deeper Gemini 3.1 Pro integration. You can get a head start with our Browser Sub-Agent Practical Guide.
Google I/O 2026 Teasers
While Google I/O typically takes place in May, April often brings preview announcements and teasers. Expect big reveals around Antigravity, Gemini, and AI Studio.
Continued AI IDE Consolidation
The ripple effects of Windsurf's acquisition will continue into April. As users look for new homes, expect heightened interest in both Antigravity and Cursor.
WWDC 2026 Leaks
Apple's WWDC 2026 is scheduled for June, but early information about Xcode 26 and iOS 26 SDK could surface in April. We'll be tracking any implications for Swift and SwiftUI development with Antigravity.
Summary
March 2026 was defined by the Antigravity v1.20.3 release, dramatic AI IDE market consolidation, and Google AI Studio's evolution into a full-stack development platform. Through over 275 articles, Antigravity Lab covered these developments as they unfolded.
In April, we'll continue delivering timely updates and practical tutorials in both Japanese and English. Our goal remains the same — helping you build better software with AI tools that keep getting more powerful.
