OPENCOVEN · PERSISTENT AI FAMILIARS
Named familiars with memory, tools, identity, and continuity — running locally, inside your projects, on your terms.
Claude Code · Anthropic 
Codex · OpenAI + more adapter-ready Familiars keep a name, role, memory, and place in the work across every session.
Coven keeps execution bounded to explicit projects and tools. Not a harness — the layer beneath.
Codex, Claude Code, CastCodes, dashboards, and docs built to fit together.
Open framework, inspectable architecture, practical extension points — yours to modify.
Architecture
Coven sits between every supported agent CLI and the project you're actually working in. Commands flow down, output and memory flow up, and every boundary is explicit.

Pick any node to inspect how it fits into the runtime.
How It Works
Memory, sessions, harnesses, and tools are the four moving parts. Each tab is a working preview of how that piece behaves in a real Coven session.
Memory
Project context, decisions, and preferences accumulate per familiar across sessions. Step through the timeline on the right to see how a familiar's working memory grows from one session to the next.
Sessions
Each harness run is a session record bound to a directory and a familiar. Filter the list on the right to see how Coven tracks running, idle, and archived work — all visible, never abandoned.
Harnesses
Codex, Claude Code, and any future harness plug in through the same neutral interface. Click a harness on the right to see how it shows up inside the runtime.
Tools
The tool gateway mediates filesystem, git, shell, and web access. Pick a tool category to see the contract Coven enforces before that tool ever runs.
Compare
Same agent CLIs, different runtime around them. Pick a row to see how each option actually behaves.

Cross-session memory
Raw harnesses lose state when the chat ends; most other tools save chat history but not curated working memory per familiar. Coven stores explicit notes that persist and surface in the next session.
Live Demo
Watch the runtime check harnesses, launch a familiar, detach, list sessions, and resume. Use the pause control to stop at any step.
Quick Start
Coven runs locally inside the projects you already have. Verify, start, and resume — memory persists across every session.
01 · Verify
npx @opencoven/cli doctor Checks your environment and detects supported harnesses — Codex, Claude Code, and more.
02 · Start a session
coven run claude "fix the failing tests" Launches a project-scoped session through Coven's managed PTY, bound to the current working directory.
03 · Resume anywhere
coven sessions Interactive browser to rejoin, summon, archive, or view logs — work picks up where you left off.
Ecosystem
OpenCoven turns AI from a blank chatbox into a durable workspace: familiars with memory and tools, local runtime control, open dashboards, desktop surfaces, and an ecosystem builders can inspect, customize, and own.
