Hi, I’m Janos, the creator of PromptFast. Every developer building with AI faces the same bottleneck: testing a prompt requires running an entire pipeline. Change one word in your system prompt, spin up your environment, wait through multiple API calls, dig through logs, repeat. For multi-agent systems, this loop can take minutes - for hours of iteration work. PromptFast is a subscription-based...

Hi, I’m Janos, the creator of TryYourPrompt. New release is live! I’ve just shipped a fresh update with two big improvements: Token usage & cost display – You can now see exactly how many tokens your request used and what it costs, right inside the app. Dynamic variables in prompts – Inject custom variables into your prompts and make them more flexible, dynamic, and context-aware. The idea came...

Hi, I’m Janos, the creator of TryYourPrompt. The idea came while working on multi-agent AI applications, where even a tiny prompt adjustment meant re-running the entire system. I’d spend more time waiting for API calls and debugging orchestration than actually improving the logic. That constant friction made me realize how much creative and technical energy was being wasted. I wanted to change...
