This tool might be expensive for production use, as other buyers say, however, after working with it, it’s a great deal for building MVPs, prototypes, and proof-of-concepts.

I use DiaFlow to rapidly develop an AI backend with multiple LLMs and RAG flows. I can send a JSON payload to a DiaFlow webhook, process it through my custom flow(s), and send the output back to my REST API. That's what I was looking for. Now I can use Wordpress as frontend and develop my MVP as Wordpress plugin.

DiaFlow supports about 12 model providers, including OpenAI, all also BYOK.

I can use six providers on credits—no need for separate subscriptions. That saves me at least $100/month in subscriptions. That makes it a better deal for me than N8N for RAD and occasional experiments.

The team are working to bring down the usage cost.

DiaFlow built-in support for vector storage, databases, and lets me design complex multi-step workflows no-code (though there’s a Python component). Many tools limit you to two steps (unless you pay extra)—this one doesn’t.

I can change the entire backend in 10 minutes. Adding an LLM is 5 minutes work. Writing the prompt is most of the work. The entire backend is no-code, and the interface is practical. Easy to work with.

I hope the team succeed in bringing down the usage cost. That might convince more people to acquire the tool.

In itself, the tool is exactly what I was looking for the past few months, an N8N type app LTD, so I can have a monthly budget to experiment with AI online and learn how it works.

If you're a developer and want to develop a quick RAD backend for your Golden Idea, work out some sudden inspiration, or would just love to scout out AI and LLM's and learn how they work, without the technical overhead, this is the right tool for you.
