open-source Framework core in Zig
Zypher — A Web Framework Built for Control, Performance, and Clarity.
Inspired by Django. Powered by Zig. Designed for engineers who want to understand their stack.
Fast & predictable
Performance is a design constraint. Zypher favors fixed costs, clear lifetimes, and explicit behavior.
Explicit over magic
Routing, middleware, templates, and state are visible in code. Less guessing, more control.
Built with Zig
Zig’s approach to memory and compile-time capabilities enables a framework that’s small, sharp, and auditable.
Modular architecture
Bring what you need. Leave what you don’t. Zypher is designed to be extended without hiding the internals.
Readable by default
Zypher is built to be learned. The public API stays explicit, and the internals stay approachable for contributors.
const zy = @import("zypher");
pub fn main() !void {
var app = zy.App.init(.{ .allocator = zy.heap.page_allocator });
app.middleware(zy.middleware.requestId());
app.middleware(zy.middleware.logger(.{ .format = .common }));
app.get("/", struct {
pub fn handler(ctx: *zy.Context) !void {
try ctx.text(200, "Zypher says hello.");
}
}.handler);
try app.listen(.{ .port = 8080, .host = "0.0.0.0" });
