★ TOP MOVER
garrytan/gstackWATCHTypeScript▲ 365 /day★ 108,288

This repo packages 23 opinionated Claude Code tools used by Garry Tan (Y Combinator CEO) for software development. It's gaining traction because it offers a ready-made, CEO-level workflow for AI-assisted coding, covering roles from designer to QA. A caveat: it's tightly coupled to Claude Code and may not generalize to other AI assistants.

🤖 Agents & automation

fathah/hermes-desktopWATCHTypeScript▲ 232 /day★ 11,314

Hermes Desktop provides a local GUI for the Hermes AI agent, enabling users to interact with and manage the agent directly from their desktop. It's gaining traction due to the growing interest in local AI agents and the need for user-friendly interfaces. A caveat is that it depends on the Hermes agent backend, which may still be evolving.

garrytan/gbrainWATCHTypeScript▲ 221 /day★ 21,738

This repo implements an agent architecture inspired by OpenClaw and Hermes, focusing on structured reasoning and tool use. It's gaining traction due to Garry Tan's influence and the practical, opinionated design choices that simplify building autonomous agents. However, it's early-stage and may lack the robustness of more mature frameworks.

⚙️ Inference & serving

tashfeenahmed/freellmapiUSETypeScript▲ 345 /day★ 8,921

It aggregates free tiers from 16 LLM providers behind a single OpenAI-compatible endpoint, offering ~1.7B tokens/month at no cost. This is notable because it dramatically lowers the barrier for prototyping and experimentation with multiple models. However, it relies on free tiers which may have rate limits, availability issues, or be discontinued, making it unsuitable for production.

🔎 Retrieval & RAG

MemPalace/mempalaceUSEPython▲ 300 /day★ 55,045

MemPalace provides a persistent, long-term memory layer for LLMs, using ChromaDB for vector storage and MCP for context management. It's gaining traction due to its benchmarked performance and free, open-source nature, addressing a critical gap in AI memory. However, its reliance on ChromaDB may limit scalability for very large deployments.

Tooling & infra

JuliusBrussee/cavemanUSEJavaScript▲ 348 /day★ 70,269

This is a Claude Code skill that rewrites prompts in a terse, caveman-like style, reducing token usage by ~65% while maintaining output quality. It's gaining traction as a practical, humorous way to slash API costs and latency for LLM interactions, especially for repetitive or simple tasks. Caveat: effectiveness may degrade for complex, nuanced instructions where precision matters.
