## Decision facts: open-webui

- **Adopt for:** Suitable for developers working with large language models who require a user-friendly interface and support for multiple APIs including Ollama and OpenAI.

## Choose when

### Choose ai-gateway if…

- ai-gateway is primarily Go; open-webui is Python.
- License: ai-gateway is Apache-2.0, open-webui is Other.
- Tags unique to ai-gateway: ai-gateway, ai-infrastructure, guardrails, litellm.
- Also covers Computer Vision.
- ai-gateway ships Docker support for self-hosted deployment.

### Choose open-webui if…

- open-webui is primarily Python; ai-gateway is Go.
- License: open-webui is Other, ai-gateway is Apache-2.0.
- Tags unique to open-webui: ai, openai, self-hosted.
- When you need to integrate multiple AI services, such as Ollama and OpenAI, into a unified user interface.

## When NOT to use ai-gateway

- 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 open-webui

- When looking for tooling that exclusively supports APIs other than Ollama and OpenAI, as these are specific areas of focus for open-webui.
- If the requirement is a highly specialized interface tailored to specific tasks rather than a general AI interaction platform.
