Comparisons

Choose by where templates live, when they load, and where rendering happens.

tool	best fit	component typing	compile/load model	rendering model

Choose gsx

Choose gsx when you want JSX-like calls and HTML-shaped component bodies while keeping expressions, component inputs, and builds in Go. It is especially useful when class, attribute, and contextual-escaping rules should be part of the template language. The JSX-like syntax does not bring a JavaScript toolchain with it: gsx compiles to Go and ships as a Go binary, with no Node.js runtime.

Choose templ

Choose templ when you prefer its Go-first syntax or need its existing ecosystem. Interop is structural: gsx.Node and templ.Component both expose Render(context.Context, io.Writer) error, so gsx nodes work where templ components are accepted. See the runnable Interop examples.

Choose html/template

Choose html/template when the standard library is the priority or templates must be parsed or replaced at runtime. Choose gsx when templates can be compiled with the application and component calls should be checked by Go.

Choose client-side JSX

Choose React or another JSX-based client framework for browser-owned state and rich client interaction. Choose gsx for server-rendered HTML, with JavaScript islands where needed.
