GitHub Trending — 2026-06-26
TL;DR
A varied day: TypeScript and Python dominate the top 10, with strong momentum behind AI-agent tooling (Google's design.md spec for visual identity, MinerU's document-to-LLM pipeline, and an AI-driven value-investing research framework). The biggest single-day gainer is mauriceboe/TREK, a self-hosted travel planner, followed by the Buffett/Munger-inspired Claude Code investing framework and Google's design spec — all three picked up over 1,000 stars today.
Top 10

2. google-labs-code/design.md (+2,319 stars today)
A format spec that lets coding agents understand and consistently apply a project's visual design system — essentially a "design contract" for AI-generated UI.
3. commaai/openpilot (+67 stars today)
An open-source operating system for robotics that powers driver-assistance features on 300+ supported car models.
4. kunchenguid/no-mistakes (+412 stars today)
