Show HN: Prompteus – Visual workflow builder for shipping better AI features

We built Prompteus to help devs build and manage AI features without the mess — no more prompt spaghetti or scattered "hardcoded" AI API calls.

Design workflows visually, deploy as APIs, and get built-in caching, logging, rate limits, and model orchestration (OpenAI, Anthropic, Mistral, etc.).

It’s like Zapier for LLMs — but dev-friendly. Free up to 50k requests/month.
