## A11Y Boost

A11Y Boost is built around a simple premise: accessibility gets easier when the people writing markup and drawing interfaces actually understand it. Rather than selling an enterprise audit suite, the project focuses on education, pairing a regularly updated news feed and a library of practical articles with small, purpose-built utilities that catch common mistakes early in the build process.

The most prominent tool is a heading structure checker. It inspects the h1-to-h6 outline of any page so authors can confirm their document hierarchy is logical, which is one of the most frequent causes of screen-reader confusion and audit failures. It is offered in two forms: a Chrome browser extension for checking pages in the browser as you work, and a web portal version for quick URL-based inspections.

Beyond tooling, A11Y Boost positions itself as a community hub rather than a product vendor. It is proudly made in Australia, publishes an accessibility statement for its own site, and openly invites sponsors and contributors to get involved through its contact page and GitHub. Everything currently listed on the site is free to use.

**Pricing & Plans:** All listed content and tools are free. The site is supported by sponsors and contributors rather than paid subscriptions; there is no published paid tier.

- **Heading structure checker (extension) - A Chrome extension t:** Heading structure checker (extension) - A Chrome extension that inspects the heading outline of the page you are currently viewing, so structural problems surface during development rather than in a late-stage audit.
- **Heading check web portal - A browser-based version of the sa:** Heading check web portal - A browser-based version of the same checker that takes a URL and visualizes the h1-h6 hierarchy, useful for reviewing pages you did not build yourself.
- **Accessibility news feed - A curated stream of updates from t:** Accessibility news feed - A curated stream of updates from the accessibility world, helping practitioners keep pace with standards changes, tooling, and community discussion.
- **In-depth article library - Longer-form guidance and explaine:** In-depth article library - Longer-form guidance and explainers that translate accessibility principles into decisions developers and designers can act on.
- **Open and community-supported - Source and issue tracking are:** Open and community-supported - Source and issue tracking are handled on GitHub, and the project openly recruits sponsors and contributors.

**Strengths:** Completely free to use, with no account or seat limits required; Narrow, well-scoped tools that solve one recurring problem cleanly; Education-first approach that explains the why, not just the what; Actively maintained and community-supported, with recent content and open GitHub development

**Limitations:** The tool set is intentionally small, so it does not replace a full accessibility auditing suite; Content and tooling are oriented toward heading and semantic structure rather than visual contrast or interaction testing; Coverage of news and articles is most useful to English-speaking practitioners

## 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
