CodeLoom is a free, open-source desktop application that turns your workstation into a private, offline AI coding environment. Instead of locking you into a single model, it lets you orchestrate multiple open-source LLMs — Mistral, Llama, Phi, and more — as interchangeable threads, each assigned to a different cognitive task. Every inference runs locally on your hardware via backends like llama.cpp, ExLlama, and MLX, so your source code never leaves your machine. No cloud dependencies, no telemetry, no user accounts, and no subscription walls. The core value is its multi-weave architecture: you can spin up to five concurrent model sessions in one workspace, each with its own context and conversation history. Contextual Thread Fusion lets you chain model outputs — a small model drafts code, a larger one expands it — without copy-pasting. The Universal Model Manager imports models from Hugging Face, Ollama, or local GGUF/GPTQ files and automatically optimizes quantization (4-bit, 8-bit, FP16) based on your VRAM and RAM. For project-level context, Native File Looming indexes your codebase (up to 100k tokens) and distributes relevant slices across model threads. For team use, real-time collaborative editing shares a loom session over your local network via WebSocket — no internet required. Intelligent Prompt Looms let you create reusable templates that send the same code to multiple models for different analyses (security, performance, style) in one click. The interface is available in 12 languages, and the app runs on Windows (x64), macOS (Apple Silicon + Intel), and Linux (x64/ARM). The trade-off: you need decent hardware (16 GB RAM minimum, 6 GB VRAM recommended) and you won't get cloud-based collaboration or hosted models. CodeLoom sits in a niche between cloud assistants like GitHub Copilot and Continue.dev. It's not a Copilot replacement — there's no API, no cloud sync, and setup requires downloading models manually. But for developers who treat data privacy as non-negotiable and have the hardware to run local models, it's a genuinely capable option.
