Built for Terminal Warriors & Senior Engineers
Every feature designed to eliminate context-switching and accelerate your delivery cycle.
Multi-Model Hot Swapping
Switch between Claude 3.7, DeepSeek R1, GPT-4o, and Gemini mid-task without resetting context. Bring your own keys or use Rayu-hosted credits.
$ rayu /model deepseek-r1Model Context Protocol (MCP)
Native JSON-RPC client for Model Context Protocol servers. Connect databases (Postgres, Redis), GitHub PRs, cloud providers, and browser automation.
mcp.call("postgres/query")Parallel Agent Swarms
Spawn subagents that work concurrently on frontend UI, backend endpoints, and test suites with shared memory and conflict resolution.
$ rayu spawn --agents=3Self-Healing Test Cycles
Runs pytest, bun test, or cargo test automatically. Captures compiler errors, diagnoses failures, and patches code until all tests pass 100%.
✓ 47 tests passed in 0.8sLocal & Air-Gapped Modes
Run 100% offline with local Ollama, LM Studio, or vLLM instances. No proprietary code ever touches a public cloud server.
$ rayu /connect ollamaPersistent Workspace Memory
Rayu records project architecture rules, custom linters, and past bug resolutions in local memory files, retaining context across team sessions.

Engineered from bare metal for zero lock-in, extreme speed, and full Model Context Protocol standard compliance.

Live Hosted Model Catalog
Copy a Rayu model ID directly into your API request and compare its current credit charges and capabilities.
This lists every globally enabled model. Your plan and API-key scope determine which models your key can invoke.
Built & Praised by Real Software Engineers
Real feedback from engineering leaders, founders, and students who ship code with Rayu CLI every day.
“What sets Rayu apart from OpenCode and the rest of the open-source field is per-agent model assignment — Gemini on frontend, Claude Sonnet on backend, DeepSeek R1 running the orchestrator.”
“It's cool that Cambodia gets to own a tool like this, instead of just reaching for Claude Code every time. The local CLI performance is unbelievable.”
“Genuinely fun to use, and faster than Claude Code or OpenCode at getting to a good result. The deterministic AST diffs save us hours every sprint.”
“It ships image and video generation built in, plus 600+ MCP tools, so our frontend engineers can stay inside one terminal for the whole development cycle.”
