The Context Database for AI Agents

OpenViking (ov)

OpenViking unifies agent memory, knowledge RAG, and skills in one self-evolving context layer — organized like a filesystem, deployed inside your own environment. Open-source core, with a private-delivery Enterprise edition for teams that need licensing, controls, and support.

Context, treated as infrastructure

Agents outgrow prompt stuffing and fragmented vector stores. ov gives them one consistent way to read, write, and retrieve everything they know.

01

One filesystem for context

Memory, knowledge, and skills live as files under viking:// paths — a single namespace instead of scattered stores and glue code.

02

Tiered loading, fewer tokens

Context loads in layers — abstract, overview, details — so agents read only what the task needs and token spend stays flat as knowledge grows.

03

Memory that compounds

Sessions distill into durable memory automatically. On the LoCoMo benchmark, agent accuracy rises from 57% to 80% — agents get smarter with use.

Data boundary

Your context never leaves your environment

Licensing verifies an ES256-signed lease locally — no agent content is sent to us. The only thing that crosses the boundary is a minimal, preference-gated operational signal.

Stays local: agent context, indexes, raw content, queries.
Leaves (minimal, opt-in): license key + optional operational telemetry.
