Original sources are credited below. **Related teardown**[What Cursor actually runs →](https://www.thetechstack.com/teardowns/cursor) Current tools / 25 ## Documented stack Source, access date, and confidence stay attached to each row. **Documented snapshot: 2025-06-10.** 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.
