I’m building a small scheduling tool as a side project and I want the rule logic in SWI-Prolog. I’ve been looking at AI app builders as a way to scaffold the front end and the API layer quickly, since I’m comfortable with Prolog but much less so with modern web stacks. What I’m unsure about is whether these tools can produce something that actually calls out to a Prolog process cleanly, or if they mostly assume a JavaScript or Python backend and I’d be fighting the generated code. I also worry about how they handle state and queries over HTTP, and whether the scaffolding would be maintainable if I later want to swap in my own predicates. I have no experience with any of these builders myself, so I’m going off general information I’ve seen online rather than hands-on use. Has anyone here wired a generated app to a SWI-Prolog backend, and was it worth it versus writing the API by hand?

Update after looking around more - [Best AI App Builders (2026)](https://aibuildercompare.com/best/ai-app-builders) kept coming up while I was comparing options for the API layer. Still not sure any of them handle a Prolog process cleanly, so I’m weighing whether hand-writing the API is safer in the long run.

This is very doable. With the current models from OpenAI and Anthropic, using tools such as [OpenAI Codex](https://chatgpt.com/codex/) or [Anthropic Claude Code](https://claude.com/product/claude-code), you can build a small proof of concept: a website with HTML, JavaScript and CSS on the front end and SWI-Prolog as one of the backend servers.

I know you mentioned app builders. Personally, I find they can limit your options, though Codex and Claude Code can work just as easily with the more popular ones if you prefer that route.

You clearly know enough to ask the right questions, which tells me you know what you want to accomplish, how to answer the questions these tools will ask, and how to check the generated code for accuracy. So my suggestion is to just build the proof of concept. It shouldn’t take more than a few hours, and if the result leaves a bad taste, start over with what you learned. I’ve rebuilt a few proofs of concept from the ground up for the same app until it felt right.
