# ladybird vs x-algorithm

ladybird and x-algorithm share 4 technologies: Tokio, Google, log, and env_logger. Both are written in Rust.

- [LadybirdBrowser/ladybird](https://seerepo.com/r/LadybirdBrowser/ladybird): Truly independent web browser
- [xai-org/x-algorithm](https://seerepo.com/r/xai-org/x-algorithm): Algorithm powering the For You feed on X

## What they share and what sets them apart

- In common: Tokio, Google, log, env_logger
- Only in ladybird: core-ktx, constraintlayout, swiperefreshlayout, androidx.appcompat:appcompat, cryptography, jxl
- Only in x-algorithm: FastAPI, axum, confluent-kafka, rdkafka, pyarrow, Redis, arrow, object_store, moka, heed, Kafka, Google Cloud Storage, tower, google-cloud-auth, jax, optax, orbax-checkpoint, parquet, opentelemetry-api, prometheus, tracing, OpenTelemetry, opentelemetry-exporter-otlp-proto-grpc, prometheus-client, tracing-subscriber, psutil

| Tests | 23,104 test files. 9.7% of its code files have a test that imports them | 19 test files. 1.1% 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.
