# Find every site that runs on a technology

Published 9 November 2026 on the [DigStory blog](https://digstory.io/blog.md).

> Use DigStory's technology pages to list the domains on a CDN, email provider, hosting network or SaaS platform, see who adopted or left it, and export the list.

"Which companies use this provider?" sounds like a question for a sales database. Often the answer is already public, written in the DNS records every company has to publish to make the service work.

DigStory reads those records for you and groups domains by the technologies they point to: DNS and email providers, CDNs, hosting networks and SaaS platforms.

## Browse the catalog

Open **Technologies** to see every technology DigStory detects, largest first, with how many domains use each one right now. Open one and you get:

- a short description of what it is,
- the number of domains currently using it,
- the domains themselves, each with the date DigStory first saw it there.

Technology also appears on every domain page: the technologies a domain uses now, and in its timeline, when each one was adopted or dropped.

## Use cases

### Build a prospect list

If you sell a migration service, an integration or a competing product, the customers of a given platform are your market. A technology page is that list, with dates: domains that showed up recently are teams that just made a decision and may still be setting things up.

### Track a competitor's wins and losses

Watch the domains you care about and every `+ TECH` and `- TECH` event tells you when a company moved to or away from a provider. For a whole segment at once, collections show the moves between technologies across a curated set of domains.

### Size a market

The domain count on each technology page is a quick, comparable measure of a provider's footprint. Check it over time to see who is growing.

### Audit your own estate

Look up your own domains to make sure nothing still points at a service you stopped paying for. A leftover CNAME to a de-provisioned SaaS account is an easy target for subdomain takeover.

## Export and API

Visitors and free teams see the first 10 domains of each technology. Paid plans list them all, export them as **CSV**, and pull them through the API:

```bash
curl -H "Authorization: Bearer dg_…" \
  "https://localhost/api/v1/technologies"

curl -H "Authorization: Bearer dg_…" \
  "https://localhost/api/v1/technologies/{slug}"
```

The first call lists the technologies and their counts; the second pages through one technology's domains, using the slug from its page URL.
