Strong positioning! Simulating real users pre-launch is a big gap in AI QA/security workflows.
The PQL would be - create first scenario → run first simulation job → review results in dashboard, right?
If you build out usage-based plans, I have a couple of suggestions if you don't mind;
• Run 1–2 shadow-billing cycles before go-live so sim job counts and minutes align with what customers expect to see on invoices.
• Add a gentle in-app meter with 50/80/100% alerts and a one-click ‘lock spend’—protects trust while encouraging healthy upgrades.
Let me know what you think!
This is great, and congrats on the launch! Curious, do you have any plans to offer functionality for testing other AI apps/platforms outside of chatbots in the future? Our team is building a dynamic AI-generated roadmap for new business owners and have been looking for more tools to test out the variety of different prompts.
Awesome launch 🚀
Really well-designed product that's super easy to setup and use. "Models are temporary, evals are forever" as they say, and simulation is an emerging approach to AI application testing that's going to be a core workflow for builders.
Amazing job with the product! Looks like exactly what I would want for pen testing agents before pushing to prod :)
@wylans Thanks Wyatt, hopefully you get a chance to take it for a spin 🙏 Congrats on YC and the new startup!
It's been an incredible journey getting this out to prod. We've made millions of tiny decisions in crafting this tool, and I hope you'll all love it as much as we do.
Snowglobe solves a problem that I think every creator working with AI can relate to. I don't think understanding your bot's behavior has ever been easier.
On the technical/scale side, we encountered plenty of problems I can't wait to write about including
the state of serverless inference
scaling systems with complex AI/LLM pipelines
Dealing with huge reliability and fault tolerance issues
building ai tools into the dev ecosystem
Happy to field questions or help out!
So excited to finally launch Snowglobe today! Personally for me, we kept hearing from guardrails open source users how challenging it was to figure out what was working vs not for AI applications. Manually curated datasets never ended up giving the confidence needed to ship to prod. With Snowglobe, you can generate hundreds of realistic, simulated conversations and see how your application performs! Super excited to see how you test your AI apps!
Wonderful idea - it could be very tedious for UAT and stress testing... I hope it could be hassle free with your tool. Congrats on the launch!
