Llamafile

79/100open sourceexplicit relation

Llamafile by Mozilla packages a complete LLM — model weights, inference engine, and OpenAI-compatible API server — into a single executable file that runs on Mac, Windows, Linux, FreeBSD, and OpenBSD with no installation. Built on llama.cpp and Cosmopolitan Libc for cross-platform portability, it delivers GPU-accelerated inference when available and falls back to optimized CPU execution. Supports GGUF models with a built-in web chat UI and REST API for integration.

100% free and open-source under the Apache-2.0 license ($0 software licensing fee, 20k+★ on GitHub). Created by Mozilla Ocho and Justine Tunney, Llamafile packages open-weight LLMs into single-file Actually Portable Executables (APE) that run locally on Linux, macOS, Windows, FreeBSD, NetBSD, and OpenBSD with zero dependencies (no Python, no CUDA toolkit). Features an embedded OpenAI-compatible HTTP server, web chat UI, and automatic GPU acceleration (Metal, CUDA, ROCm). Users pay $0 in software fees, relying solely on local device hardware.Review →

PrivateGPT

82/100open sourceexplicit relation

PrivateGPT enables fully private document interaction using GPT-powered RAG without any data leaving your machine. Ingest documents (PDF, DOCX, TXT, and more) and chat with them using local LLMs via Ollama or remote providers. Built on LlamaIndex with Qdrant vector storage. 57,200+ GitHub stars, Apache 2.0 licensed. The go-to solution for air-gapped environments, regulated industries, and anyone who needs document Q&A without cloud data exposure.

100% free and open-source under the Apache-2.0 license ($0 software cost). PrivateGPT by Zylon is an air-gapped, privacy-first local RAG platform and OpenAI-compatible API built on FastAPI, LlamaIndex, and embedded Qdrant vector storage. Enables local document ingestion (PDF, DOCX, TXT, CSV, EPUB) and zero-data-leakage question answering via local LLMs (Ollama, llama.cpp) and local embeddings (HuggingFace BGE). Includes a built-in Gradio Workbench UI. Zero cloud subscriptions or token costs when run locally on private hardware.Review →

llm-d

open sourceexplicit relation

llm-d is an open-source Kubernetes-native stack for distributed LLM inference with cache-aware routing and disaggregated serving. It separates prefill and decode stages across different GPU pools for optimal resource utilization, routes requests to nodes with warm KV caches, and integrates with vLLM as the serving engine. Apache-2.0 licensed with 2,900+ GitHub stars.

Free and 100% open source under the Apache-2.0 license as a CNCF Sandbox project. llm-d delivers Kubernetes-native distributed LLM inference orchestration, prefill/decode disaggregation, prefix-cache aware routing, and multi-tiered KV-cache offloading on top of vLLM and SGLang with zero software licensing fees.
