Back in May, I launched PromptPerf on Product Hunt. Got 161 upvotes and some brutally honest feedback:
- "Sadly no Gemini"
- "API key friction"
- "Need multi-model comparison" — multiple users
I spent the last 7 months building exactly what they asked for. I had been informed that there is a 6 months wait period from ProductHunt before a relaunch hence I decided to make small changes over the period and monitor user behaviours.
What changed:
❌ Before: 3 OpenAI models only
✅ Now: 100+ models (GPT-4o, Claude, Gemini, Llama, DeepSeek)
❌ Before: Required API key to try
✅ Now: Works without signup — free trial
❌ Before: Test one model at a time
✅ Now: Compare 5 models side-by-side
What I learned:
Your first launch is research, not revenue
The comments matter more than upvotes
Building what users ask for > building what you think is cool
We're live on Product Hunt today. Would love your feedback or just an upvote if you think this is useful. Product Launch
