## 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 open-webui if…

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

### Choose deep-research if…

- deep-research is primarily JavaScript; open-webui is Python.
- License: deep-research is MIT, open-webui is Other.
- Tags unique to deep-research: anthropic, deep-research, deep-research-api, deepresearch.
- Also covers Vector Databases.
- deep-research ships Docker support for self-hosted deployment.

## 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.

## When NOT to use deep-research

- 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.
