PromptPerf 2.0 - Find which AI wins for YOUR prompts. Test 100+ models free.

The Problem: You're using ChatGPT because everyone does. But is it actually the best AI for YOUR specific task? Maybe Claude writes better code. Maybe Llama is 10x cheaper and just as good. The Solution: PromptPerf lets you test your actual prompts across 100+ AI models simultaneously and shows you which one wins. ✨ What's New in 2.0: • 100+ models • Speed benchmarks • Ready-to-use templates • Save tests and re-run when models update

Hey Product Hunt! 👋

7 months ago I launched PromptPerf here and you gave me exactly the feedback I needed. Today I'm back with 2.0 — and I built everything you asked for.

Your feedback → What I built:

"Sadly no Gemini"

→ Now there's 100+ models: GPT-4o, Claude 3.5, Gemini 2.5, Llama 3.3, DeepSeek V3 & more

"API key friction"

→ Now you can try free without signup - see results instantly

"multi-model comparison"

→ Now compare 5 models side-by-side in one test

Special for PH: 50% off lifetime deal → $99 (normally $199)

I'd love to know: Which AI models are you using now vs 6 months ago? Has the landscape changed for you?

Thanks for shaping this product. Happy to answer any questions! 🚀

Tried PromptPerf today and honestly really liked it. It’s simple, quick to use, and actually helps you see which prompts work better without overthinking it. I’ve been doing a lot of prompt testing lately and this makes the process way easier. Nice work, excited to keep using it.
