Rather than selling a bundled subscription, it asks you to plug in your own API key and then talks directly to the provider, which usually works out far cheaper than a flat monthly chatbot plan for moderate users. Because the connection goes straight to the model provider, replies tend to arrive quickly and you are not queued behind other users on a shared account. A model selector lets you jump between a frontier model for hard questions and a cheaper one for routine drafting, and you can adjust the system prompt so the assistant keeps your preferred tone, language or output format. Beyond plain text, Chatworm handles multimodal tasks: it can read text out loud, analyse an image you upload, and generate pictures with models that support it. The client is open source and runs in the browser, and because history lives with your own account, you stay in control of your data and costs. **Pricing & Plans:** The Chatworm client is free; you pay the model provider directly for the API tokens you use, so cost depends on your own usage rather than a fixed subscription. - **Bring your own API key:** Add your own OpenAI (or compatible) API key and chat with no monthly subscription — you pay only for what the model uses. - **Model switching:** Switch between available language models, including GPT-4-class and cheaper options, from a single dropdown. - **Customizable AI behaviour:** Edit the system prompt and settings so the assistant matches your tone, language or task. - **Voice, vision and image tools:** Have replies read aloud, send images for analysis, and generate images with supported models. - **Open-source client:** The client is open source and runs in the browser, so you keep control of your keys and conversations. **Strengths:** No monthly subscription — you pay only for the tokens your model actually consumes; Direct API connection typically means faster responses than shared hosted chatbots; Open-source client you can inspect or self-host; Text-to-speech, image analysis and image generation in one interface **Limitations:** You must sign up with and manage an API key from a model provider; Costs vary with usage and can be hard to predict without monitoring; The public demo page needs JavaScript, so a browser with JS enabled is required [Profile (Markdown)](https://openaitools.app/tool/chatworm.md) ## 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 [Profile (Markdown)](https://openaitools.app/tool/open-webui.md) ## Frequently Asked Questions ### How do Chatworm and Open WebUI compare in monthly traffic?
