Java vs. OCaml vs. Objective-C vs. Windmill Comparison Chart

OCaml is a general-purpose, industrial-strength programming language with an emphasis on expressiveness and safety. OCaml’s powerful type system means more bugs are caught at compile time, and large, complex codebases are easier to maintain. This makes it a good language for running critical code. At the same time, sophisticated inference makes the type system unobtrusive, creating a smooth developer experience. One is a bytecode compiler which generates small, portable executables and is very fast. The other is a native code compiler that produces more efficient machine code; its performance matches the highest standards of modern compilers. OCaml has great support for the most popular editors. VS Code is recommended for beginners, and for power users there is deep integration with Vim and Emacs. OCaml has a rich and dynamic community and best-in-class tooling.

​Windmill is an open source developer platform and workflow engine that transforms scripts into auto-generated UIs, APIs, and cron jobs, enabling the composition of workflows or data pipelines for building complex, data-intensive applications with ease. Supporting various languages, Windmill allows users to write and deploy software up to ten times faster, operating with high reliability and observability on a self-hostable job orchestrator. It features auto-generated user interfaces based on script parameters, a low-code app editor for creating custom UIs, and a flow editor for constructing workflows using a drag-and-drop interface. Windmill manages dependencies automatically, offers robust permissioning and monitoring, and provides various triggers including webhooks, schedules, CLI, Slack, and emails. Users can develop scripts locally with their preferred code editors, preview them, and deploy using the CLI.
