## Open WebUI

Open WebUI is an open-source, self-hosted interface for working with AI models. Instead of renting access to a single vendor's chatbot, you run the interface on your own hardware or cloud tenancy, then connect whatever models you want: local runtimes such as Ollama, OpenAI-compatible endpoints, Anthropic, or a mix of local and remote. Everything a team produces — conversations, prompts, models, skills and tools — stays in an environment you administer.

The platform has grown well beyond a chat window. Retrieval-augmented generation, web search, document understanding, voice input and output, and vision are built in, and Python tools, functions and pipelines let developers script custom behaviour and share it. On the operations side it offers enterprise features such as SSO, role-based access control, audit logs, data residency options, and on-premises, hybrid or fully air-gapped deployment for regulated environments. White-labeling and custom branding are also available for organizations that want their own look.

Open WebUI is distributed free of charge under an open-source license and can be installed with a single pip or Docker command, with no account required to get running. A separate enterprise offering is available for organizations that want commercial support, compliance guarantees and managed rollout help, which is quoted on contact. A large community maintains a public hub of prompts, models, tools and functions, so much of what teams need is already shared and ready to install.

**Pricing & Plans:** The core platform is free and open source, installable via pip or Docker with no account required. An enterprise tier with support, compliance and deployment assistance is quoted on contact.

- **Any Model, Any Endpoint:** Connect local runtimes like Ollama alongside OpenAI-compatible and Anthropic APIs, and switch between them inside one interface.
- **Retrieval and Search Built In:** RAG over your own documents, web search and citation-aware answers come standard, so responses are grounded in real sources.
- **Python Tools, Functions and Pipelines:** Extend the platform with Python code to add custom tooling, preprocessing, and multi-step pipelines, then share them with others.
- **Enterprise Controls:** SSO, RBAC, audit logs, data residency, and on-premises, hybrid or air-gapped deployment for organisations with strict requirements.
- **Community Hub:** Browse and install prompts, models, skills and tools contributed by hundreds of thousands of community members.

**Strengths:** Free and open source with no account needed to install; Works with local and cloud models through a single interface; Strong privacy posture: your data and models stay on your infrastructure; Extensive enterprise features including SSO, RBAC and audit logs

**Limitations:** Self-hosting requires you to handle servers, updates and backups; Some enterprise capabilities and support sit behind a paid, quote-based tier; Feature depth means a learning curve for non-technical administrators; Local model performance depends heavily on your own hardware

## PromptMage

PromptMage is an open-source Python framework built to simplify the development of complex, multi-step applications powered by large language models. Rather than treating prompts as throwaway strings scattered through code, it makes prompts first-class citizens with built-in version control, so teams can track changes, compare iterations, and collaborate on the exact wording that drives their application.

The framework centers on a workflow that mirrors how good LLM apps actually get built. You define and iterate on prompts inside an integrated playground, evaluate them with manual and automatic testing, and then expose the resulting logic through an automatically generated FastAPI backend. That combination means the same artifact you prototype in is the one you deploy, cutting the drift between experimentation and production.

PromptMage is designed as a self-hosted solution, which suits teams that want prompt and data handling to stay within their own infrastructure. It is aimed at both small teams and larger enterprises, and the project positions itself as a pragmatic answer to the gap in LLM workflow management. Because it is self-hosted and open source, there is no per-seat fee for the framework itself, though the LLM providers your application calls are billed separately. The project documentation carries an explicit warning that PromptMage is in alpha state and under active development, so APIs and features may change at any time.

**Pricing & Plans:** Free and open source. PromptMage is a self-hosted framework with no listed subscription or per-seat pricing; you pay only for the LLM APIs and infrastructure your application uses.

- **Integrated version control for prompts:** Treat prompts as first-class artifacts with built-in versioning, so you can track how each prompt evolves and collaborate with teammates without losing earlier iterations.
- **Interactive prompt playground:** Test, compare, and refine prompts in an intuitive playground built into your workflow, enabling rapid iteration rather than ad-hoc copy-paste testing.
- **Auto-generated FastAPI API:** Prompts and workflows defined in PromptMage are exposed through an automatically generated FastAPI backend for straightforward integration and deployment.
- **Evaluation and testing mode:** Assess prompt quality with manual and automatic testing before shipping, so you know how a change affects output reliability across scenarios.
- **Self-hosted deployment:** Run the whole framework on your own laptop or server, keeping prompts, workflows, and data inside infrastructure you control.
- **Typed, Pythonic building:** Type hints are used throughout for automatic inference and validation, reducing boilerplate when composing multi-step LLM logic.

**Strengths:** Free and open source, with no vendor lock-in; Self-hosted, so prompts and data stay in your own infrastructure; Bundles version control, a playground, testing, and API generation in one framework; FastAPI auto-generation removes boilerplate between prototype and deployment

**Limitations:** Explicitly labeled alpha, so the API and features may change without notice; Self-hosted only — you need to run and maintain the server yourself; Requires Python and LLM API experience to get real value; Documentation, while solid, is still maturing alongside the framework
