Cloudflare Workers RPC Now Enables Seamless Python and JavaScript Interop
irvinebroque · x · 2026-08-03
Cloudflare announced that its Workers RPC feature now supports cross-language calls, allowing developers to seamlessly invoke methods and share objects between Python and JavaScript.
Previously, getting programs written in different languages to communicate required building custom APIs or adopting serialization formats like protobuf. Now, the RPC system built into Workers automatically handles the translation between JS and Python without requiring additional dependencies or schema definitions, greatly simplifying cross-language workflows.
