Via Open Source Universal Integration Layer Connects AI Tools to Shared Context Bus

Via is a new open source project positioned as a universal integration layer for AI tools. It connects multiple AI tools — including Claude, Cursor, Windsurf, ChatGPT, LangChain, and others — to a shared context, task, and memory bus. This means your work-in-progress, conversation history, and task state persist across different tools, sessions, and machines.

Key Details

• Shared bus architecture: Via provides a centralized context, task, and memory bus that all connected AI tools can read from and write to.
• Supported tools (from source): Claude, Cursor, Windsurf, ChatGPT, LangChain, and every other AI tool — the “every other” suggests broad extensibility, but only these are named.
• Persistence across boundaries: Work follows you across every tool, every session, and every machine. This hints at cloud or local sync capability, though no specifics are given in the source.
• Open source release: The project is available now, announced on r/LocalLLaMA. Exact license, repository URL, installation commands, and version are not provided in the source text.

What This Means for Developers

If you’re using multiple AI coding agents (e.g., Cursor for editing, Claude for code review, and LangChain for orchestration), Via aims to eliminate the friction of re-explaining context or transferring tasks manually. Instead of copying chat history or exporting project state, Via acts as a universal backbone that synchronizes context across all your AI tools. This is particularly relevant for teams or individuals who switch between different AI assistants depending on the task.

Who It’s For

Developers who regularly use multiple AI coding agents and want a unified context that persists across sessions and tools.
