suds-py3
Lightweight SOAP client
Decision gist · record as of 2026-08-14
Yes, if you need to consume SOAP web services in Python 3 and can accept a library that has not been released since 2021. The package is stable, has no dependencies, and the repository remains active. Not recommended if you require active feature development or support for cutting-edge SOAP/WS-Security standards, or if you are building new services (use modern REST/gRPC alternatives instead).AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Low install friction with no runtime dependencies.
- Repository is active with recent commits (last commit 2026-04-13), though the package itself has not been released since 2021-11-15.
- Suitable for stable SOAP integration work where active development is not required.

What it is and what it does
suds-py3 is a SOAP client for Python 3 that lets you call web services by loading their WSDL definitions at runtime. Rather than generating code upfront, it reads the service schema on the fly and exposes service methods as Python objects, supporting multiple SOAP binding styles (Document/Literal, RPC/Literal, RPC/Encoded) and basic HTTP authentication. The library handles type objectification, enumerations, and unicode transparently.
It is a maintained fork of the original Suds library, which is no longer actively developed. The package has no external runtime dependencies, making it lightweight to install. It is used for integrating with legacy SOAP-based web services and systems that still rely on WSDL-driven service discovery.
Use it for
- Calling legacy SOAP web services from Python 3 applications without code generation
- Integrating with enterprise systems (Java, .NET WCF) that expose WSDL-based SOAP endpoints
- Rapid prototyping against WSDL services where schema changes frequently
- Adding HTTP Basic authentication to SOAP service calls
- Inspecting and debugging WSDL service definitions at runtime
