Show HN: Waylou / a multi-provider CLI coding agent / fork of Gemini CLI

Waylou ACE CLI, an open-source AI coding assistant forked from Google Gemini CLI, launches with multi-provider support for Gemini, OpenAI, Anthropic, Ollama, and DeepSeek models. The tool enables autonomous operation, model team routing, and secure execution, aiming to provide a unified terminal interface for developers.

Your terminal. Your models. Your rules. Waylou ACE CLI is an open-source AI coding assistant that runs directly in your terminal. It connects to multiple AI models — Gemini, OpenAI, Anthropic, Ollama, DeepSeek — through a single, unified interface. Forked from Google Gemini CLI, Waylou extends the foundation with multi-provider support, autonomous operation, and an architecture designed for extensibility. Status:Active development. Core functionality works. Provider layer and CLI features are under heavy development. Contributions welcome. | Capability | Waylou ACE CLI | Gemini CLI | |---|---|---| | Multi-provider Gemini, OpenAI, Claude, local | ✅ | ❌ | | BYOK — Bring Your Own Key | ✅ | ❌ | | Provider orchestration & team routing | ✅ | ❌ | | Headless / autonomous mode | ✅ | ✅ | | MCP Model Context Protocol | ✅ | ✅ | | ACE compliance specification | ✅ | ❌ | | VS Code companion | ✅ | ❌ | | Apache 2.0 open source | ✅ | ✅ | Install globally npm install -g @waylou/cli Or run instantly npx @waylou/cli Launch waylou Use any model, any provider. Swap mid-session. Route tasks to the right model based on capability, speed, or cost. Supported providers: Google Gemini — Gemini 2.5, 3.0 1M token context OpenAI — GPT-4, GPT-4o Anthropic — Claude 3.5, Claude 4 Ollama — Local models Llama, Mistral, Gemma DeepSeek — DeepSeek V3, R1 Form teams of models with different roles — architect, coder, reviewer. The orchestrator distributes tasks using configurable strategies capability-best, round-robin, parallel-vote . The Agentic Coding Environment specification standardizes agent behavior across three compliance levels: CORE — File operations, shell commands, web fetch STANDARD — MCP integration, checkpointing, sandbox, memory ENTERPRISE — Policy engine, audit logging, team orchestration Run in CI/CD pipelines, scripts, and automated workflows: waylou -p "Review this PR and summarize the changes" --output-format json Semantic code search combining vector embeddings SQLite-vec with AST analysis Tree-sitter for precise, relevant context retrieval. Secure execution via macOS Seatbelt, Docker, or Podman. - Node.js 20+ - npm 9+ npm install -g @waylou/cli git clone https://github.com/helis-d/waylou.git cd waylou npm install npm run build node run.js Set your provider API keys: export GEMINI API KEY="your-key" Google Gemini export OPENAI API KEY="your-key" OpenAI export ANTHROPIC API KEY="your-key" Anthropic export DEEPSEEK API KEY="your-key" DeepSeek For local models, install Ollama https://ollama.com and run: waylou --provider ollama CLI Ink/React UI │ ▼ Core Engine Agent Loop, Tools, Prompts │ ▼ Provider Layer Gemini | OpenAI | Anthropic | Ollama | DeepSeek │ ▼ AI APIs See ARCHITECTURE.md /helis-d/waylou/blob/main/ARCHITECTURE.md for the full system design. | Package | Description | |---|---| @waylou/cli | Terminal UI & CLI binary | @waylou/cli-core | Core agent logic, tools, prompts | @waylou/cli-provider | Multi-AI provider abstraction | @waylou/ace-spec | ACE specification & validation | @waylou/autonomous-engine | Headless / autonomous operation | @waylou/context-engine | Vector & AST semantic search | @waylou/sandbox | Secure execution environment | @waylou/cli-sdk | Public SDK for extensions | See ROADMAP.md /helis-d/waylou/blob/main/ROADMAP.md for planned features and priorities.
