Why it's different

More than a list of installs.

Back-end tools

Data warehouses, observability, identity and help desks, found in DNS, subdomains, certificates and hiring, not just page code.

Dated changes

Every adoption and drop has a date, so you can filter to this month and act while it matters.

Pay per record

One credit returns one company record. Searches are free, and you never pay for an empty page.

Questions

The API, answered.

An API that returns which software companies use. Incumbently's API also returns when each company adopted or dropped a tool, so you can act on switches, not just installs.

Yes, for business software. BuiltWith's API covers front-end website technologies. Incumbently's API covers 1,500+ business software products, including back-end tools a website never shows, and dates every adoption and drop. Pro starts at $149 a month with 1,000 credits.

One credit returns one company record. Searching the catalogue and checking your balance are free. Each response says how many credits it used and how many you have left.

Pro includes 1,000 credits a month and Max 5,000. Extra credits can be added to a workspace and never expire.

60 requests a minute per key, and up to 100 records per page. Pass page=2 and so on for more.
