Ask HN: Decent Builtwith alternative for finding leads?

4•Poomba•4mo ago
Is there a cost-friendly Builtwith alternative that lets me find businesses that use a specific tech product? I find Builtwith a bit too expensive for my needs as it's $299 for 2 technologies, and I have 10+ I want find businesses for. And BuiltWith doesn't seem to have a lot of technologies I'm looking for either. I've tried Wappalyzer too, and though it's much less expensive, it also doesn't have data for a lot of niche technologies I'm targeting either.

For context, I own my own tech consulting business and want to find businesses that are trying to seriously start/expand an engineering team. I've already exhausted asking my network, existing clients, etc, and thinking of expanding now into more outbound stuff.

I was thinking of finding businesses that started using a particular Javascript framework or started using a "starter-level" devops product like BitBucket, as a way to find those businesses that are just beginning to scale their dev team

Are there any good alternatives out there? It feels like the type of tool that the HN crowd would be building...

Have you tried Bloomberry [1]? For instance, u can find companies that just started a Github organization profile or just started a self-hosted Gitlab instance (it scans DNS records for new instances). I think builtwith only focuses on front end facing technologies not backend.

[1] Disclaimer: this is an API product I built myself and recently launched at bloomberry.com

Poomba•4mo ago
never heard of it but will give it a try. but off the bat I need an UI not just an API
Poomba•4mo ago
[update] just signed up and very curious where the data comes from? I managed to find businesses that use Github which is incredibly useful for me. It is missing some Javascript frameworks like NextJS but i think thats not a big deal…

Where does the technographic data come from? Is it scraped from websites? Or are you relying on another 3rd party source?

Is there anyway to get some trends data like how Builtwith has trend insights on how many of the top 100k websites use something like NextJS over time?

AznHisoka•4mo ago
A variety of sources, not just web scraping. Including DNS records, DNS traffic and more. All collected by us.

As for trends, while we dont have something like Builtwith trends, you can easily collect all the data yourself via the API see how its trending using your favorite BI tool.

And yes we are missing some JS frameworks like nextjs and react. We chose to focus more on paid products instead. Builtwith (and its competitors like Whatruns, Wappalyzer and Similartech) is missing data on a lot of backoffice/backend products which we have data for

Poomba•4mo ago
You guys need a way for users to download flat csvs. And also a Zoominfo or Apollo integration if you want more SDR/BDRs to use it. I like the company info you return but you lack contact details right? That is important to users like me…

Other than that the data is what I exactly need. Was able to find businesses that use Github, Gitlab and Grafana rather easily!

AznHisoka•4mo ago
PS. We just launched a simple UI for you to download CSVs.

Also, I wrote something on other Builtwith alternatives if you're interested: https://bloomberry.com/blog/5-builtwith-alternatives-for-tec... (if you're only looking at front-end tech, then Builtwith is probably the best bet FWIW)

Bang on, I've been working on something that I've intended to be a cost-effective alternative to BuiltWith. I was thinking about just selling the datasets and allowing users to extract whatever they need from it. What technologies are you after?
