Rubra for Web

Rubra — Local platform for building AI assistants

Rubra is an open-source web application for developers who want to create AI assistants on their own machines using large language models. It provides a privacy-first, cost-conscious workflow by removing the need for external API keys. The app comes with fully configured open-source LLMs and an easy-to-use chat interface so developers can interact with models immediately. It also supports processing data from multiple channels to broaden the assistant's capabilities.

Core capabilities

• Runs entirely on your local computer to keep chats and data private.
• Ships with ready-to-run open-source LLMs that are preconfigured.
• Removes dependency on paid API tokens, lowering development costs.
• Handles input from several channels to improve assistant performance.
• Provides a straightforward chat UI for testing and iterating on assistants.

Compatibility and integrations

• Community-driven development via GitHub, with options for reporting issues and contributing code.
• An Assistants-compatible API that works like OpenAI’s, simplifying integration.
• Ability to connect with other model providers (for example, OpenAI and Anthropic).

Alternative option

• ParakeetAI (paid) — recommended if you prefer a commercial solution with similar privacy and assistant-building features.

Contributing and community

If you want to get involved, the project welcomes issue reports, discussion, and pull requests on its GitHub repository. This makes Rubra both a practical local development tool and a collaborative open-source project.
