GitHub Trending & AI Updates , June 23, 2026

Some open source projects and AI research worth noting today. From liquid glass UI on the web to agent workspace architecture.

1. AgentSpace , Human + Agent in One Workspace

HKUDS/AgentSpace (316 stars) , a framework that blurs the line between human and AI agent in a single workspace. The concept: it's not just agents working independently, but real-time collaboration between humans and multiple agents in the same environment.

What's the difference from other frameworks? AgentSpace focuses on a shared workspace , all agents and humans have access to the same resources, can see each other's work, and coordinate natively. This is relevant to the rising agent orchestration trend.

Status: ✅ Released, open source.

2. Liquid Glass UI , Apple-Style Glassmorphism on the Web

samasante/liquid-glass (229 stars) , a headless React lens that renders an Apple-style liquid glass effect on the web. Not your usual CSS glassmorphism , this is a real optical refraction effect, including distortion, chromatic aberration, and lighting reactive to mouse position.

From a technical perspective: the headless component approach means you can use this effect in any framework. Rendered via Canvas with a shader effect , not a CSS filter. For those building premium landing pages , an open source alternative for effects usually only found on Apple.com or Stripe.

Status: ✅ Released, open source.

3. Codex Orange Book , Comprehensive Guide to Codex CLI

bozhouDev/codex-orange-book (607 stars) , an open source guide from installation to practical case studies for OpenAI Codex CLI. Covers: environment setup, specific prompt engineering for Codex, editor integration, and real case studies.

For those still confused about how to maximize Codex: this is a solid reference, including a PDF download.

Status: ✅ Released, open source.

4. Swift Package Index Joins Apple

Swift Package Index (178 HN points) acquired by Apple. For the Swift ecosystem, this is a strong signal that Apple is serious about Swift as a server-side and cross-platform language , not just iOS. So far, Swift Package Index has been a search engine for Swift packages. Under Apple, it will most likely be integrated directly into Xcode and the Swift toolchain.

For Swift backend developers: expect improved package discovery and a more tightly integrated registry.

Status: ✅ Confirmed from the Swift Package Index blog.

5. Apache OpenOffice 4.2 , Release After 4 Years

Apache OpenOffice 4.2 released after almost 4 years without a major update. It is still used in government and educational institutions in Indonesia. Updates: PDF import/export improvement, ODF 1.4 compliance, and improved compatibility with newer Microsoft Office formats.

Status: ✅ Released.

6. Trending GitHub , Last 24 Hours

Several repos with significant growth:

• kanavtwtgg/birds.cafe (722 stars) , new project with explosive growth, needs further observation
• BohemiaInteractive/CWR (177 stars) , Arma Cold War Assault source code released. For the Arma modding community, this is big news
• Rhombus Language 1.0 (83pts HN) , new language from the Racket ecosystem. Scheme-like syntax with modern static typing

Conclusion

Today is a bit quieter compared to yesterday , but the signals are still interesting. AgentSpace gives a new perspective on human-agent collaboration, Liquid Glass shows that open source can catch up to Apple-grade visual quality.

We will monitor again tomorrow.
