Nomos Cloud
Nomos Cloud is the hosted platform for domain-driven API generation and agent execution auditing. It makes AI systems auditable and debuggable via append-only decision traces.
The Short Version
Every AI agent takes actions. Most leave no trace of why. Nomos Cloud is an agent execution gateway that emits “chains of truth”—append-only, queryable decision traces that capture not just what happened, but why it was allowed. Think of it as event sourcing for AI: every intent, directive, policy evaluation, and approval becomes a permanent, auditable record.
The Problem
The industry is waking up to context graphs—the idea that the most valuable thing you can store isn’t the AI’s chain-of-thought, but the decision context: who requested it, what policy approved it, what precedent justified it, and what artifacts it produced.
Most agent systems either:
- Have no audit trail at all
- Log raw text that’s impossible to query
- Lose context when sessions end
Nomos captures the decision graph as first-class data, making every agent action traceable back to its authorization and forward to its consequences.
Our Approach
Event-Sourced Architecture
Nomos is built on event sourcing principles: every change is captured as an immutable event. This means:
- Deterministic replay: Rebuild any state by replaying events
- Local-first: Work offline, sync when connected
- Full auditability: Every decision is traceable
Core Concepts: Intents → Directives → Events
The data model follows a clear flow:
- Intents: What the user or agent wants to do
- Directives: What actions are permitted based on policy
- Events: What actually happened, with full context
This isn’t a blockchain—there’s no global consensus. Instead, Nomos models many overlapping, queryable chains by workspace, run, timeline, correlation, or entity.
Stories, Not Logs
A normal audit log is a crime against human attention. Nomos stores templates and variables, rendering human-readable stories on the read path:
“Sarah asked: Who owes us money? Agent queried Xero. Found 12 overdue invoices totaling £47,230. Agent drafted reminders. Finance approved. Messages sent.”
The raw structured trace remains canonical—stories are just a view. This avoids persisting PII-heavy narratives while keeping the audit trail complete.
How It Works
OpenAPI/MCP Generation from Domain Models
Define business domains in a typed, validated format. Nomos generates:
- REST APIs with OpenAPI specs
- SDKs in multiple languages
- CLI tools
- MCP tools for AI agent integration
Everything compiles from the domain model, eliminating drift between documentation, API, and implementation.
Cloudflare-Native Hosting
Built entirely on Cloudflare primitives:
- Workers: HTTP APIs
- Durable Objects: Per-timeline sequencing
- R2: Immutable ledger storage
- Queues: Async indexing
- Workflows: Heavy derivations
- D1: Query indexes
Every tenant gets logically isolated storage. Compute scales to zero. No Kubernetes to manage.
Adapters for Everything
The SDK includes adapters that transform existing telemetry into Nomos entries:
- OpenTelemetry spans become events with correlation preserved
- OpenAI and Anthropic tool calls become directives
- MCP tool invocations become policy-checked directives
You don’t rewrite your agent—you instrument it with a few lines.
Product Features
@nomos/router-sdk
The open-source TypeScript SDK: entry schema definitions, ID generation (UUIDv7 for time-sortable IDs), story template helpers, safe redaction utilities, and adapters. MIT-licensed.
Nomos Cloud Service
The managed service: ingest API, query API, story rendering, web dashboard, and all compliance/enterprise features. Customers get a workspace URL, drop in the SDK, and start capturing traces immediately.
Web Dashboard
Timeline visualization showing entries as a scrollable, zoomable graph. Story view rendering human-readable narratives. Chain explorer for following correlation links. Entity history showing all actions affecting a specific customer/account/resource.
Who It’s For
AI Agent Developers
Anyone building autonomous systems needs to understand what their agents did and why, debug unexpected behavior, and demonstrate compliance. Nomos gives them a single place to capture and query decision traces across their entire agent fleet.
Regulated Industries
Finance, healthcare, legal, and government need audit trails that survive legal scrutiny. Nomos provides tamper-evident logs, cryptographic proofs, and the ability to reconstruct exactly what happened at any point.
Enterprise AI Teams
Large organizations deploying AI across multiple teams need centralized visibility: which agents are running, what actions they’re taking, which policies are being applied. Nomos is the control plane for enterprise AI governance.
Business Model
The Neo4j Model
The underlying technology—the ledger schema, the SDK, the adapters—is fully open-source under a permissive license. Anyone can run Nomos on their own infrastructure.
The business model is convenience: businesses pay for hosted infrastructure, compliance guarantees, a web dashboard with visualizations, and enterprise features they don’t want to build themselves.
Pricing
- Free Tier: Generous limits for hobbyists and startups
- Usage-Based: Pay for entries stored and queries executed
- Enterprise: SOC 2, SSO, RBAC, custom retention, dedicated support
Compliance & Certifications
For regulated industries: SOC 2 Type II certification, GDPR data processing agreements, HIPAA BAAs for healthcare, and custom data residency options. Tamper-evident hash chaining with cryptographic proofs available for audit.
