It's a split decision.
Choose AnythingLLM for a local-first assistant on macOS, Windows, Linux, or Android, with document chat, meeting summaries, and an advertised developer API. Choose Open WebUI for a self-hosted web workspace that connects named local and cloud model providers, supports Python extensions, and can run air-gapped. Neither is a universal winner: AnythingLLM centers on a local app, while Open WebUI gives teams a broader model-connection and deployment layer. Check exact licenses and export paths before standardizing.

02Pricing at real usage
AnythingLLM’s free local app requires no account or API key, and its homepage says there are no token limits for on-device use. Its paid plans are for private instances: Basic is $50/month and includes a custom subdomain plus a bring-your-own LLM API key; Pro is $99/month with priority resources and a 72-hour support SLA. Enterprise pricing is custom and includes on-premise deployment, SSO, RBAC, and custom integrations. Annual prices aren’t listed.
Open WebUI lists a $0-forever self-hosted tier with no seat or request limits. Branding changes above 50 users in a rolling 30-day window require an enterprise agreement. Supporter is $60 per seat per year; monthly pricing is not listed. Enterprise is custom, and Terminals and Tether require an enterprise license. Budget separately for compute and any connected model provider. Ask how private-instance billing scales with seats and resources.
03API, SDKs and integration
AnythingLLM advertises a developer API and custom tool builder for extending workflows. Its features include document chat and web search, and its meeting assistant works with any meeting platform. The product pages don’t name an API protocol, SDK language, or CLI, so validate the API contract and support expectations before building a production integration.
Open WebUI connects to Ollama, OpenAI, Anthropic, and compatible services. Its extension path is Python pipelines and code, and its toolkit includes voice, vision, retrieval, generation, and search. The docs are linked from the product site, but its product pages don’t name a separate SDK or CLI. Both products have community resources; Open WebUI also offers a library for sharing prompts, models, tools, and functions. For either product, confirm authentication, versioning, and upgrade compatibility against the docs before making an integration a dependency.
04Open source, self-hosting and lock-in
Both products are open source and self-hostable, but the product pages don’t identify their license names. Check the current license text before redistributing, modifying, or embedding either in a commercial product.
AnythingLLM runs as a local desktop app on macOS, Windows, and Linux, with an Android app and a self-hosted multi-user option. Its Enterprise plan adds on-premise deployment. Open WebUI can run on your hardware, in your cloud, or in an air-gapped environment, giving operators more explicit deployment choices.
Neither vendor publishes a data-export guarantee on its product pages. Before committing, ask how to export conversations, documents, configurations, and user data, and what formats are supported. Model portability is clearer: Open WebUI connects to several named providers, while AnythingLLM emphasizes local models and its developer API.
Questions people ask
Which is better for a fully local AI setup?
AnythingLLM is the more direct fit for an individual workstation: its desktop app runs locally, supports local models, and keeps document processing on-device. Open WebUI can also run on local hardware, but its main distinction is a self-hosted interface connecting local or cloud models.
Can Open WebUI connect to cloud models?
Yes. Open WebUI lists connections to OpenAI, Anthropic, and compatible services, alongside Ollama. That lets operators use local and cloud models through one interface. Account for the connected provider’s own pricing and limits when estimating production costs.
Does AnythingLLM have a developer API?
AnythingLLM advertises a developer API and custom tool builder for workflows. Its product pages don’t name a protocol, SDK, or CLI, so developers should review the docs and confirm the API’s authentication, versioning, and support terms before relying on it.
Which is better for an air-gapped deployment?
Open WebUI explicitly lists air-gapped deployment, making it the clearer option when that requirement is part of the architecture. AnythingLLM offers local use and an Enterprise on-premise deployment option, but its product pages don’t specifically describe an air-gapped mode.
