Ask HN: Recommended technographic API?

[Poomba]

Does anyone know of any good technographic APIs? I run a dev consultancy and basically want to know what tech stack they currently use (ie what they use for CI/CD or security), so it can help me prepare when i talk to a prospect. I know Builtwith is the leader in this space but i feel its lacking a bit when it comes to finding tech that isnt front end or JS focused.

I’ve tried using the Anthropic API but most of the time it seems to give me hallucinated results (based on the results for companies I know their tech stack)

Ideally something that doesnt cost an arm and an leg :)

Why doesn’t Claude work for this? Especially if you pass the HTML/JS scripts.

If you want an API, options include Bloomberry and Wappalyzer.

Just give the page to chatgpt and ask what they use. Give them as much info as you can.

I have tried that but 1) it hallucinated a lot of technologies as I mentioned and 2) it only detects the front end stuff not backend

See the reply up above. You can't just expect LLMs to give you good answers if you're not providing lots of context to it. Also, make sure you give it guardrails. Like say you can't only infer it from the JS scripts on their website, external AJAX calls, job postings posted directly on their website, their Github profile, and engineering blog... Otherwise you're gonna get lots of made up stuff :)

Besides the context, ask it to specify how it knows a given tech is being used.

I just realized this whole thread is an ad. haha. GFY
