Veridex vs PydanticAI

PydanticAI is the typed Python agent framework. If you're Python-shop, it's a strong default. Veridex is its TypeScript-first peer, with deeper governance.

Dimension	PydanticAI	Veridex
Language	Python	TypeScript / Node / Bun
Tool typing	Pydantic models	Zod schemas
Validation	First-class	First-class
Policy engine	Light	Priority-ordered rules + packs
Approvals	Manual	First-class verdict
Memory tiers	Out of scope	Four tiers + reconciler
Sandbox	Out of scope	Built-in
Audit	Logging	Hash-chained, signed bundles
Multi-tenancy	Out of scope	Control plane

Cross-language interop

PydanticAI exposes tools over HTTP/MCP; Veridex imports them via fromMcpServer or fromOpenAPI. Veridex exposes its own tools the same way for PydanticAI agents to consume.

import { fromMcpServer } from '@veridex/agents/transports';
 
const pythonTools = await fromMcpServer({
  url: 'https://python-services.example.com/mcp',
  auth: { tokenProvider },
  trust: 'imported',
});

The PEP enforces our safety guarantees regardless of source language.

Choose

Backend is Python-only and stays that way? PydanticAI.
TypeScript / Node / browser, or polyglot fleet? Veridex.
Compliance-heavy workflows in either ecosystem? Veridex + PydanticAI behind tools.
