## 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

## sidellama

sidellama is a small Chrome extension that turns your browser into a chat client for open-source language models. Rather than locking you into one provider, it connects to whatever model access you already have: a local Ollama server, a local LM Studio server, or open-source models hosted through Groq. The extension itself is lightweight (under a megabyte) and open source, with the code published on GitHub.

What makes it browser-augmented is page context. When you are reading an article or documentation, you can feed the visible text of that page into the conversation, or switch to HTML mode to share the page source — a developer-oriented option that is intentionally resource intensive and paired with a character limit so you do not blow past your context window. Web search augmentation adds live public data: type a query, choose DuckDuckGo or Brave as the source, and sidellama runs an asynchronous search to ground its answer.

A persona system lets you build and modify your own assistants. You can create, configure, and switch between different system prompts and custom instructions, so the same model can act as a coding helper, a summarizer, or a research companion depending on the persona you select. The listing shows version 0.0.1, last updated August 29, 2024, with a small but strongly positive rating base and no data collection declared by the developer.

**Pricing & Plans:** sidellama is free. There is no charge for the extension itself; you cover the cost of whichever model access you connect, such as your own local Ollama or LM Studio setup or a paid/limited Groq API tier.

- **Connect local or hosted open-source models:** Point sidellama at a local Ollama or LM Studio server, or use open-source models through Groq.
- **Page context augmentation:** Share the text of the page you are reading, or its HTML source in development mode, with a configurable character limit.
- **Custom personas:** Create and modify personal assistants with system prompts and custom instructions for different tasks.
- **Web search augmentation:** Run asynchronous searches through DuckDuckGo or Brave and answer questions using live public data.
- **Open-source codebase:** The extension is open source, with the code available in a public GitHub repository.

**Strengths:** Free and open source, with code on GitHub; Works with local Ollama and LM Studio servers for private use; Page context and web search grounding in one small extension; Custom personas via system prompts and custom instructions

**Limitations:** Last updated August 2024; feature set is intentionally minimal; Very small user base and only a couple of ratings; Web search augmentation is basic, not a full research pipeline; HTML mode is resource intensive and intended for development only
