Documented stack

Source, access date, and confidence stay attached to each row.

Documented snapshot: 2026-07-10. This describes the record’s stated observation date, not a live inventory.

Company verification: The company has not verified this record. Individual claims can still cite direct company statements.

What the confidence labels and dates mean

Confirmed: the record attributes the claim to a company statement. This is not independent proof of current deployment.
Inferred: the record draws a conclusion from technical evidence.
Reported: the record attributes the claim to a third party.

“Source accessed” is the date the researcher recorded visiting the source. It is not the source’s publication date or a new verification of the company’s stack. Publication dates and deployment scope are not consistently recorded in this dataset.

A tool listing does not establish company-wide adoption, internal permissions, security controls, or suitability for your team. Check the source and its scope before using a record in a purchasing decision.

Movement

What changed

Moved away from

MongoDBdatabase · Confirmed in place for caching scenarios as of the 2022 Pragmatic Engineer interview, but absent from Linear's own 2026 careers-page "Our tech" list. Status of 'previous' is inferred from this list comparison, not an explicit migration statement from Linear — could be an oversight in the careers copy rather than a true retirement; no public writeup found explaining a removal or replacement.
