Agentis Requirements: What You Need Before You Install

The short answer

Agentis runs as a pnpm monorepo on Node ≥ 20.10. That's the entire hard requirement. It ships with embedded SQLite, a bundled offline ONNX embedding model, and a content-addressed local asset store — so it boots and serves the full Brain (memory formation, semantic recall, knowledge bases) with zero external services and zero API keys. A model runtime is the one thing you attach afterward, and even that has a local option.

What's bundled vs. what you configure

Every row above works out of the box. Nothing in this table requires an account, a credit card, or an internet connection on first boot.

What you'll want to add — and when

Agentis boots complete, but an empty workspace can't think yet. The one thing you attach next is a model runtime: a CLI harness (Claude Code, Codex, Cursor), a local model, or any OpenAI-compatible HTTP endpoint. Everything else below is genuinely optional, added only when you need it:

Storage and platform notes

SQLite is single-writer by design — this is an intentional choice for a local-first, single-tenant operator deployment, not a scaling shortcut you'll hit later. Plan disk space around two things that grow over time: the SQLite database itself, and the content-addressed asset store under AGENTIS_ASSETS_DIR, which holds every image, document, and generated artifact your agents produce (deduplicated, so re-generating the same output twice costs nothing extra).

Agentis runs on Windows, macOS, and Linux. The examples throughout these docs use POSIX shell syntax; swap in the PowerShell equivalent if that's your environment.
