How this list is ordered. Specifiction scores each tool on how fully its maker documents it, whether its prices are published, where the research puts it, the platforms it runs on and whether it can be tried for free (how we rank). Makers can also buy a numbered place (how Specifiction is paid for).

Check which inputs and outputs fit your task, and whether you want generation available from a terminal or inside an editor. Free-plan availability and paid-from pricing provide further comparison points. Nx, quicktype and Stainless are among the options, alongside TypeSpec and OpenAPI Generator. Weigh the listed language support and workflow features against the kind of code or starter structure you need to produce.
