After using this tool across many projects, here are 15 use cases that have paid for the subscription many times over.
Real experience with AI tools
When I first started using AI coding tools — OpenClaw and Hermes Agent — every bug sent me straight to a search engine. I'd paste error messages into Chinese AI models and get back answers that sounded right but didn't work. The suggestions kept piling up. None of them fixed the actual problem.
Then I tried Claude for debugging. The difference wasn't smarter answers — it was better logic. Chinese models would give me a single solution with no explanation. Claude walked through why the error happened, what the fix actually changed, and what I should check if the fix didn't work. That last part saved me the most time.
Chinese AI has improved a lot since then — several generations of models later, the answers are much better. But that experience taught me something: the best AI tool is the one that explains its reasoning, not the one that sounds most confident.

Example prompts that work
Copy any of these into StackBlitz and adapt to your context:
Spin up a Next.js project
Create a Vue + TypeScript starter
How to get the most out of StackBlitz
Start with the highest-volume task. Pick the use case you'll do most often, and perfect that prompt first.
Build a prompt library. Save your best prompts in a doc. Reuse across team members.
Add context every time. "I'm a [role] doing [task] for [audience]" gets better results than a bare request.
Iterate, don't settle. The first response is rarely the best. Ask for 3 variations and pick.
Combine with another tool. StackBlitz + a search/voice/image tool usually beats either alone.
What StackBlitz is not great at
Real-time information (use a search tool for current data)
Tasks requiring deep domain expertise you don't have
High-stakes decisions without human verification
Anything that needs the latest data from the web
