This is a public-clue stack estimate. It should not pretend to know private infrastructure, database choices, or internal service boundaries.
Start with a URL
The first output is an editable evidence pack, not a roast and not a scale score. This is the input Stack Scale Critic needed.
How it works
- 1.Validates and normalizes the public URL before any network request.
- 2.Fetches capped public HTML, response headers, scripts, assets, and cookies while revalidating redirects.
- 3.Matches direct site signals, then adds public web evidence through Gemini Google Search with a DuckDuckGo fallback.
- 4.Returns confidence-labeled technologies, evidence, caveats, unknowns, and next verification questions, with a 15-minute result cache.
