Overview

OpenViking organises everything an agent knows as a viking:// virtual filesystem of resources, memories and skills, browsed with ls, tree, read and grep, with search scoped to a subtree. Each directory carries generated summaries so agents read full content only when needed. The server needs Python 3.10+ plus an embedding model and a VLM; plugins cover Claude Code, Codex, Cursor and OpenClaw.

Who it is for: Teams wanting transparent, file-like memory shared across coding agents

Strengths

  • Memory is inspectable and editable as Markdown files under viking:// URIs
  • LoCoMo accuracy 80 to 83% for OpenClaw, Hermes and Claude Code at far fewer tokens
  • Python, Go and TypeScript SDKs plus HTTP API; multi-tenant accounts and ACLs
  • Hosted Studio playground at openviking.ai/studio; Railway one-click deploy

Weaknesses

  • AGPL-3.0 license
  • Needs both an embedding model and a vision-language model from a provider
  • Memory plugin installer is macOS/Linux only; Windows uses the beta desktop app
  • Benchmarks were run with Volcengine Doubao models

What it needs

  • no GPU
  • Docker + Compose
  • Models: Volcengine, OpenAI, Codex OAuth, Kimi, GLM
