   Project mention: 9router: route Claude Code, Cursor, or Copilot through whichever free tier you've got | dev.to | 2026-05-09

   I was crawling GitHub trending for AI infra projects when I came across decolua/9router. It's the most thoughtful "stretch your free tiers" project I've seen for AI coding tools — and it does a few things I hadn't seen combined before. Worth a 60-second rundown for anyone burning through Cursor/Claude/Copilot budgets faster than they'd like.

7. obsidian-smart-connections

   6 26 5,095 9.7 JavaScript

   Find related notes and excerpts while writing. Your link building copilot displays relevant content in graph + list view. A local embedding model powers semantic search. Zero setup. No API key.

   

   Project mention: Think with your second brain: a proper Claude Code harness for Obsidian | dev.to | 2026-05-20

   Smart Connections (repo) is the dominant Obsidian-AI plugin and does RAG over the vault. The harness uses Smart Connections' embedding cache as a secondary signal in Hybrid Mode, not as the primary retrieval mechanism.

    Project mention: Ask HN: What are tools you have made for yourself since the advent of AI | news.ycombinator.com | 2026-06-08

    Most of it has been to maximize productivity with AI

    1) Use chatgpt pro from codex cli, opencode, claude etc as you can't get it via API. This has been the biggest boost in productivity for me as I don't have to copy and paste.

    https://github.com/agentify-sh/desktop

    2) A small gate to make sure any agent cannot run destructive rm -rf or git reset --hard commands, it has saved me many many times

    https://github.com/agentify-sh/safeexec

    3) For mac users, summarizes and speaks out loud after codex finishes a turn

    https://github.com/agentify-sh/speak

12. IntelliNode

    GitHub: GeminiWithFiles

20. gemini-plugin-cc

    19 1 44 8.7 JavaScript

    Use Gemini from Claude Code to review code or delegate tasks.

    

    Project mention: Show HN: I adapted codex-plugin-cc's design for Gemini CLI's ACP | news.ycombinator.com | 2026-03-31

    This started as a protocol / adapter exercise. codex-plugin-cc made me want the same kind of Claude Code integration for Gemini, so I built one.

    https://github.com/abiswas97/gemini-plugin-cc

    The repo is derived from openai/codex-plugin-cc, but the runtime layer is different: this plugin talks directly to Gemini CLI in ACP mode instead of Codex app-server.

    In practice, the Gemini side here is much more session-oriented:

21. removebanana

    20 1 41 4.4 JavaScript

    🍌 Remove invisible AI watermarks from Google Gemini images — npm package

    

    Project mention: Remove invisible AI watermarks from Gemini images using reverse alpha math | news.ycombinator.com | 2026-03-10

22. deliberation

    21 1 41 - JavaScript

    Ask Codex, Gemini/Antigravity, Grok (xAI), and 400+ more models through OpenRouter including Qwen, Kimi, DeepSeek for second opinions or arbiter-mediated consensus inside Claude Code.

    

    Project mention: Meet Deliberation: 400+ models is easy, knowing which ones earn a place is hard. | dev.to | 2026-06-03

    Deliberation is open source, it works in the agent you already use, and most of the models are ones you already pay for. It ships in the agent-plugins marketplace and as a standalone MCP server on npm (@antonbabenko/deliberation-mcp). Source, and a star button I would genuinely appreciate, are at github.com/antonbabenko/deliberation. Install it, point GPT and Claude at each other, and let me know where it breaks. The cheapest review still happens before you execute - just make sure every reviewer in the room is worth the wait and the cost.

23. Shiori-v1

    22 1 37 - JavaScript

    Open-source AI study companion — Google Classroom sync, Gemini AI plans, SRS flashcards, GPA predictor, AI quiz, MCP server for Claude Code. Try demo at shiori-v1.vercel.app
