Why Nomos

Built for clarity, designed for AI

Nomos is the first backend framework designed from the ground up for AI-assisted development, combining predictable patterns with automatic safety.

Filepath-Based APIs

Your file structure IS your API. LLMs understand this pattern natively. No configuration files, no magic, no surprises.

Sandboxed Plugins

LLM-generated code runs in isolation first. Automatic validation before production. Enable with confidence, disable instantly.

Full Observability

Every decision traced. Every request logged. Every plugin execution measured. Debug with data, not guesswork.

Features

Batteries included, not opinions imposed

Everything you need to build production backends, with the flexibility to customize anything.

Authorization System

Policy-based access control with full audit trails. Every decision includes evidence and rationale. Built for compliance and debugging.

Admin UI

Pre-built interface with SSR and client-side hydration. Auto-generated CRUD from your APIs. Customizable components, accessible by default.

Self-Documenting APIs

OpenAPI specs generated from your file structure. Built-in API explorer and testing UI. Types stay in sync automatically.

Plugin Architecture

Hooks without the legacy. Sandbox validation before enabling. Runtime integrity checks. Community marketplace ready.

Observability & Diagnostics

Request tracing, performance metrics, decision artifacts. Everything logged and queryable from day one.

Database & ORM

Prisma integrated by default. Automatic migrations. Schema-first or code-first. Multi-database support.

AI-Native Development

LLMs read your structure. You keep control.

Nomos is designed so that AI can understand and extend your code safely, while you maintain full visibility and control.

Predictable Structure

File organization defines API behavior. No hidden configuration. LLMs trained on GitHub understand this pattern intuitively.

Automatic Validation

Plugins run in sandbox first. Security checks, dependency resolution, and integrity verification happen automatically before anything touches production.

Always Auditable

Every authorization decision, every plugin execution, every API call is traced with full context. You know exactly what happened and why.

Built With Nomos

Complete production applications. One LLM prompt each.

These aren't demos. They're real platforms, each generated from a single prompt and running in production. Click to explore.

Each platform was generated from a single detailed prompt, refined through LLM iterations, and validated in Nomos's sandbox before deployment. View the prompts and iterations in each project's repository.
