#1 Claude Mar 28
JWT vs session-based auth tradeoffs
JWTs are stateless and scale horizontally, but revocation is hard without a blocklist. Sessions require server-side state but allow instant invalidation. For your use case with multiple services, JWT with short expiry + refresh tokens is the standard approach.
#2 Claude Mar 28
Refactor auth middleware implementation
Extract token validation into a pure function. Compose middleware: rateLimiter → tokenExtractor → claimsValidator → permissionsGuard. Each step returns either a validated context or throws typed errors.
#3 ChatGPT Mar 29
Unit tests for auth middleware
Use Jest with custom matchers for auth errors. Mock the token validator at the module boundary. Test each middleware in isolation, then integration-test the composed chain with a mock Express app.
#4 Gemini Mar 30
Security audit checklist
Checklist: token expiry enforced, HttpOnly cookies, CORS policy locked, refresh token rotation, secrets in env vars only, audit log on failed auth attempts.

Your data stays on your machine.

NODUS is built on a local-first principle. Everything you capture is stored in your browser's local storage — never uploaded, never shared, never mined.

🔒

All data stored locally

Captures, tags, notes, chains, and projects live exclusively in your browser's local storage. Nothing leaves your device unless you explicitly export it.

🕵

No account, no tracking

NODUS requires no login and stores no personal information. Optional anonymous telemetry is off by default — it collects no conversation content, no identity, and is fully auditable in the source code.

💾

PRO backup is encrypted

PRO's optional backup feature uses AES-256-GCM encryption with a password you set. The encrypted file is only readable with your key — not by us.

🚫

What we never do

No reading of your conversation content, no capturing of what you save, no third-party data sharing, no advertising SDK. Telemetry is anonymous, opt-in, and auditable in the source code.

Open Core

Built in the open.

NODUS core is MIT licensed. You can read the source, fork it, and contribute. PRO features are commercial add-ons that fund ongoing development.
