How do I compile the generated scripts?

Use the 'zeroserve --pack' command; it automatically compiles .c files in the .zeroserve/scripts/ directory into eBPF objects using clang.

What are the main constraints for Zeroserve scripts?

Since they run as eBPF programs, they must avoid unbounded loops and recursion, keep stack usage minimal, and use provided SDK helpers for memory access.

Zeroserve is a zero-config, high-performance HTTPS server based on io_uring that supports scriptable request handling via eBPF.

Can these scripts handle JSON payloads?

Yes, the skill utilizes Zeroserve SDK helpers like zs_json_parse and zs_json_respond for efficient JSON manipulation within the eBPF environment.

Can I use this for reverse proxying?

Absolutely. The skill can generate logic to trigger zs_reverse_proxy based on specific request conditions like headers, paths, or query parameters.

API Development

Generates high-performance eBPF request-processing scripts in C for the Zeroserve HTTPS server.

About

This skill automates the creation of specialized C scripts for Zeroserve, a high-performance HTTP server leveraging io_uring and eBPF. It helps developers implement complex server-side logic like custom request routing, header manipulation, JSON parsing/generation, and reverse-proxying directly within the eBPF layer. By leveraging the Zeroserve SDK, the skill ensures that generated code adheres to strict eBPF constraints while providing advanced features like metadata templating and static file inspection for ultra-fast, scriptable edge logic.

Key Features

Supports JSON handling for structured data processing and dynamic responses
4 GitHub stars
Configures reverse-proxy behavior and script short-circuiting logic
Implements complex request/response logic including header and query param parsing
Optimizes scripts for eBPF constraints like stack limits and loop restrictions
Generates eBPF-compatible C code using the Zeroserve SDK

Use Cases

Implementing dynamic content templating or metadata-driven responses
Building custom authentication or request validation layers at the edge
Creating lightweight, high-performance API gateways with reverse-proxy capabilities
