# check-if-email-exists vs warp

check-if-email-exists and warp share 7 technologies: Sentry, warp, Tokio, csv, log, tracing, and tracing-subscriber. Both are written in Rust.

- [reacherhq/check-if-email-exists](https://seerepo.com/r/reacherhq/check-if-email-exists): Check if an email address exists without sending any email, written in Rust. Comes with a ⚙️ HTTP backend.
- [warpdotdev/warp](https://seerepo.com/r/warpdotdev/warp): Warp is an agentic development environment, born out of the terminal.

- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
