Magnitude
An open-source inference server that automatically picks and runs the right AI model on your own hardware, so you can use AI coding assistants offline without cloud fees or API keys.

Description
Running AI models on your own computer usually means figuring out which model your laptop can actually handle, downloading gigabytes of files, and configuring a runtime by hand — a barrier that keeps a lot of people paying for cloud APIs even when they'd rather not. Magnitude tries to remove that barrier entirely.
Magnitude is an open-source inference server that profiles your machine's hardware (CPU, memory, bandwidth), recommends models it can actually run well, then downloads, configures, and manages them automatically — loading models on demand and unloading them when idle. It plugs directly into popular AI coding assistants like Claude Code, Cline, and Pi, letting them run against local models instead of a paid API. Released under Apache 2.0, it charges nothing, sends no data off the machine, and works fully offline once set up, at the cost of being limited by whatever hardware you actually have.
💬 Our review
The short version: if you want to run an AI coding assistant without an API bill or your prompts leaving your machine, Magnitude removes the usual local-inference setup headache — the tradeoff is you're capped by your own hardware, not a cloud GPU.
Ollama and llama.cpp are the closest comparisons and both are free too, but they leave hardware profiling and model selection to you — pick the wrong model size and you get an unusably slow response or an out-of-memory crash. LM Studio solves that with a polished desktop app, but it's built around a chat UI, not wiring straight into a coding assistant's backend. Magnitude's niche is specifically the integration layer: automatic hardware-aware model selection plumbed directly into Claude Code, Cline, and Pi, which matters most for someone who wants local inference working today rather than tuning it. Since it's free and open source either way, the real cost is entirely your own hardware's ceiling, not the software.
