## 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 ax if…

- ax is primarily TypeScript; open-webui is Python.
- License: ax is Apache-2.0, open-webui is Other.
- Tags unique to ax: anthropic, claude, cohere, dspy.
- Also covers Vector Databases.

### Choose open-webui if…

- open-webui is primarily Python; ax is TypeScript.
- License: open-webui is Other, ax is Apache-2.0.
- Tags unique to open-webui: llm, 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 ax

- 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.
- Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate.

## 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.
