## The use case: how Brex deploys Cursor

Brex built a pipeline of custom self-hosted Cursor agents that generate, build, validate and self-correct code to automate the Micronaut 3 to 4 framework migration across its Kotlin microservices. One agent opens draft pull requests from Linear tickets and a second monitors CI, deploys to development environments and fixes runtime errors, with a human reviewing every change.

Summary written by usedby from the source page, in English. The figures are those of Cursor and Brex, not ours.

> We built a pipeline of custom self-hosted AI agents in Cursor that are capable of writing, building, and dynamically self-correcting code. This allowed a single engineer to migrate 180 microservices in just one month.

- **180 microservices**: “This allowed a single engineer to migrate 180 microservices in just one month.”
- **approximately 90%**: “we decreased our cost per microservice migration by approximately 90%”

> More than 70% of our engineers now use Cursor, and we've seen meaningful gains in day-to-day development, faster execution on large-scale migrations, increased rate of debugging, and even faster onboarding.
