Agents supported
Local-first isn't a feature. It's the product.
No cloud. No egress.
All memory lives in local SQLite. Your codebase never leaves your machine — not to OpenAI, not to Anthropic, not to us.
Zero API keys.
Nexus doesn't add another key to rotate. It wires into Claude Code, Cursor, and Codex's existing auth. No new credentials.
One install. Every agent.
npm i -g nexus-prime. Then nexus-prime setup claude. Done. Repeat for Cursor, Codex, Windsurf. 30 seconds per agent.
Verifiable cryptography.
Ed25519 signed license JWTs. Verified offline, every session. No network call to check your license.
62% token reduction
Cut our Claude Code token spend by 62% in the first week. Our agents stopped re-reading our entire codebase on every session.
