# leptos vs vector

leptos and vector share 10 technologies: axum, sqlx, lru, Tokio, tower, Tailwind CSS, csv, tracing, log, and tracing-subscriber. Both are written in Rust.

- [leptos-rs/leptos](https://seerepo.com/r/leptos-rs/leptos): Build fast web applications with Rust.
- [vectordotdev/vector](https://seerepo.com/r/vectordotdev/vector): A high-performance observability data pipeline.

| Tests | 202 test files. 10.7% of its code files have a test that imports them | 242 test files. 28% of its code files have a test that imports them |

- Size: Lines written by people and agents, without generated ones; code files, without tests.
- 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.
