What is bbarit-oss?

bbarit-oss is a terminal-based AI coding assistant delivered as one self-contained Rust executable that requires no separate runtime. It works with more than fifteen LLM providers — including Anthropic, OpenAI, Google, OpenRouter, and local models through Ollama — covering over a thousand models from a single registry. The agent can read and write files, execute shell commands, search code semantically, retrieve web pages, and launch parallel sub-agents on its own. It includes 295 ready-made specialist personas spanning 30 fields, automatic cross-session memory that captures lasting facts, a per-project wiki for durable codebase knowledge, and support for MCP, LSP, and custom skills. A toggle lets it reuse MCP servers and skills already configured in Claude Code or Codex. You install it with one curl command on macOS or Linux, one PowerShell line on Windows, or grab a binary from GitHub releases. The code is MIT licensed and runs entirely on your hardware; nothing phones home.

FAQ

Does it phone home?

No, your API keys and code stay on your machine.

Is my code private?

Yes, your keys and code stay on your machine and go only to the provider you choose. It is fully self-hostable; nothing routes through the vendor.

How do I install it on Windows?

One line in PowerShell: irm https://bbarit.com/agent/install.ps1 | iex — installs to %LOCALAPPDATA%\Programs\bbarit-oss and adds to PATH.

Is it free?

The agent is free and open source (MIT). You only pay your own LLM provider or run a local model for $0.

Can I use it with a local model / offline?

Yes, point it at Ollama (/ollama) to run entirely on your machine with no API key and no data leaving your computer.

Which LLM providers are supported?

Anthropic Claude, OpenAI (GPT + Codex), Google Gemini/Vertex, OpenRouter, Groq, Mistral, Together, Fireworks, DeepSeek, Cerebras, Amazon Bedrock, GitHub Copilot, and local models via Ollama — 15+ providers, 1,000+ models.

Is it related to Pi?
