autobahn-python vs orpc
Python WebSocket and WAMP vs. TypeScript API toolkit
autobahn-python provides Python libraries for asynchronous WebSocket and WAMP applications, while orpc helps TypeScript teams define API contracts, implement server procedures, and make type-safe client calls. The main difference is protocol-focused networking in autobahn-python versus contract-first API development and integrations in orpc.
autobahn-python: Build WebSocket and WAMP Applications
A Python library for building asynchronous WebSocket clients and servers, plus WAMP applications with remote procedure calls and publish-subscribe messaging. It supports Twisted and asyncio and requires Python 3.11 or later.
orpc: Build End-to-End Type-Safe APIs
oRPC is a TypeScript toolkit for defining API contracts, implementing server procedures, and calling them with end-to-end type safety. It suits teams building TypeScript APIs that need OpenAPI compatibility and integrations with common frameworks and tools.

Key differences
- autobahn-python is written in Python and supports Twisted and asyncio; orpc is a TypeScript toolkit for API development.
- autobahn-python focuses on WebSocket messaging and routed WAMP RPC and publish-subscribe; orpc focuses on shared API contracts, server procedures, and type-safe clients.
- autobahn-python requires Python 3.11 or later and WAMP applications need a router; orpc offers packages for framework integrations, schema conversion, rate limiting, and observability.
- autobahn-python's repository metadata lists its license as NOASSERTION, while its README describes it as MIT licensed; orpc lists its license as MIT.
- autobahn-python has 2.5k stars and 770 forks; orpc has 7 stars and 5 forks, figures that offer limited evidence about adoption and maintenance.
Choose autobahn-python if you…
- need Python WebSocket clients or servers with message, frame, or streaming APIs.
- want WAMP RPC and publish-subscribe with Twisted or asyncio.
- need WebSocket options such as TLS, proxies, compression, or WAMP serialization choices.
Choose orpc if you…
- want shared TypeScript API contracts connecting server implementations and client calls.
- need OpenAPI compatibility or generation, or integrations with frameworks such as Next.js or NestJS.
- use Zod, Valibot, or ArkType and want to connect schemas to JSON Schema support.
