One Surface, All Agents: Raven generates DAGs and orchestrates multiple specialized agents for complex tasks.
Raven is The Harness of Harnesses—a self-evolving multi-agent orchestration ecosystem. As a Host Agent, it brings specialized agents together through one unified surface to delegate tasks, coordinate execution, and integrate results. Its long-term vision is to extend this orchestration across devices, environments, and domains.
Built on EverMind’s self-evolving harness engine and powered by EverOS, Raven preserves context across sessions and continuously improves agent harnesses and collaborative workflows.
Built-in Agents: Raven-Research, Raven-Code, Raven-Design, and Raven-Oncall support research, coding, visual design, and unattended workflow automation.
Raven is pre-alpha. Interfaces and configuration may change quickly.
Raven's Performance on the Multi-Agent Orchestration Benchmark
Raven's modular architecture is designed for harness self-evolution and subagent creation. Its four built-in agents deliver state-of-the-art (SOTA) performance in their respective domains, combining reusable harness components with domain-specific tools, skills, and agent loops. Raven can delegate a focused task to a single agent or orchestrate multiple agents within a shared workflow. The harness they share is refined by the Raven Evolver, a separate tool that consumes Raven as a library and evaluates candidate harness changes against benchmarks; it develops the agents rather than running inside them.
All four agents are built in and ready for orchestration out of the box.
Raven-Research enables autonomous deep research for complex questions, literature reviews, and technical analysis. It delivers clear, structured reports with traceable sources, helping users understand unfamiliar domains, compare alternatives, and make informed decisions.

Raven-Code enables agentic software development, turning requirements into working, tested code. It supports feature implementation, debugging, refactoring, data processing, and data analysis, helping users build new capabilities, resolve issues, and improve code quality while following their project's conventions.

Raven-Code tops on DataAgentBench for data analysis (2026-08-24 Live)
Raven-Design performs visual design, turning ideas and content into polished visual deliverables. It creates PowerPoint slide decks, brand assets, charts, diagrams, and web interfaces, refining layout, typography, and visual consistency to help users communicate clearly and bring their ideas to life.
Raven-Design tops on PresentBench for slide generation

Raven-Oncall enables unattended workflow automation for experimentation, optimization, and continuous monitoring. It autonomously manages workflows from start to completion, sustaining progress over hours or overnight, delivering results, and involving users only when human judgment is needed.
Raven-Oncall significantly outperforms Claude Code on both quality and cost for AI4AI tasks
Raven-Oncall significantly outperforms Claude Code on both success rate and cost for AI4S tasks

Raven can connect to and orchestrate agents via ACP, CLI, or OpenAI-compatible APIs, with presets for 13 third-party agents to simplify setup, task delegation, and coordination across shared workflows. Try these agents in Raven through a unified interface!
Linux, macOS, or WSL2:
curl -fsSL https://raven.evermind.ai/install.sh | bashNative Windows PowerShell:
irm https://raven.evermind.ai/install.ps1 | iexWindows PowerShell 5.1 may reject the redirect. Use the direct installer URL instead:
irm https://raw.githubusercontent.com/EverMind-AI/Raven/refs/heads/main/install.ps1 | iexOr install from a source checkout, to develop against the code or to run what has not been released yet:
git clone https://github.com/EverMind-AI/Raven.git
cd Raven
./install.shRun as a file, install.sh installs that checkout in editable mode: raven and
its bundled plugins link back to your tree, and the TUI bundle and the served
page are built from it. A piped run installs the published wheel even from
inside a clone, so that a one-line install never picks up whatever a working
tree happens to contain. Set RAVEN_LOCAL_SRC=<dir> to force the editable
install through a pipe.
The agent products ship with raven itself: a wheel carries the agents/
product tree and copies it out to your raven home on first use, and a source
checkout reads the tree in place. Setup asks about each product and registers
the ones you take up, on the model it is tuned for or on this raven's LLM.
See agents/README.md.
