## Choose when

### Choose willow if…

- willow is primarily C; LocalAI is Go.
- License: willow is Apache-2.0, LocalAI is MIT.
- Tags unique to willow: alexa, deep-learning, echo, esp-adf.
- Also covers Inference & Serving.

### Choose LocalAI if…

- LocalAI is primarily Go; willow is C.
- License: LocalAI is MIT, willow is Apache-2.0.
- Pricing: As an open-source project under the MIT license, it is free to use and distribute..
- Tags unique to LocalAI: agents, ai, api, audio-generation.
- Also covers Computer Vision.
- Use LocalAI when you need model flexibility, as it can run different types of models (LLMs, computer vision, speech & audio) on any type of hardware.

## When NOT to use willow

- Last GitHub push was 148 days ago (slowing maintenance, Feb 13, 2026). Validate activity before betting a new project on willow.
- Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic.
- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.

## When NOT to use LocalAI

- Avoid LocalAI if you need to leverage GPU-specific optimizations for performance acceleration as it promotes no-GPU usage, potentially sacrificing speed for accessibility.
- Do not use LocalAI where specific language runtime environments are required that do not align with Go (the language in which LocalAI is written).
