Raven is an open-source ai agents project by EverMind-AI (EverMind-AI/Raven on GitHub). It has 5,303 GitHub stars and 152 forks, is released under the Apache-2.0 license, and was last updated on GitHub on 8 October 2026.
Pick a substantial, ongoing objective — a product launch, a codebase, a research program — rather than a one-off question.
Use the one-line installer for your platform, or the container route if you prefer nothing on the host but Git and Docker.
Configure the built-in agents and connect any third-party agents you already use.
Start the WebUI with raven web and give Raven its first task from the composer, with skills, playbooks, knowledge and memory attached.
Ships Raven-Research, Raven-Code, Raven-Design and Raven-Oncall agents covering research, engineering, design and operations work.
Agents improve through a runtime self-evolution loop — the project's RSI focus — with persistent memory across tasks.
External agents plug into the same ecosystem, so existing agents join the shared memory and playbooks instead of being replaced.
A browser WebUI (with a task composer exposing skills, playbooks, knowledge and memory) plus a terminal interface.
The showcase documents complete end-to-end work: a game development project, an RSI run and a full product launch executed by Raven.
One-line script installs, a container route needing only Git and Docker, and editable source-checkout installs for development.
Clone Raven if you want a source checkout; most users use the installer in the next step.
git clone https://github.com/EverMind-AI/Raven.git
cd RavenRun the official installer on Linux, macOS or WSL2 (a PowerShell route is documented for Windows).
curl -fsSL https://raven.evermind.ai/install.sh | bashStart Raven's web interface in the background and open it in your browser.

# Opens the WebUI; stop it later with: raven web --stopRaven is maintained by EverMind-AI, part of the EverMind ecosystem.
Yes — it is open source under the Apache-2.0 license. You pay for the models your agents call.
Raven's agents drive LLMs, so you need model access through the providers you configure; Raven itself charges nothing.
Those are frameworks for assembling agent teams in code; Raven is a persistent, productized ecosystem — built-in agents, shared memory, a WebUI, and a self-evolution loop — that also connects external agents.
Run the one-line installer, then raven web, and delegate your first task from the composer.
