# flink vs supertokens-core

flink and supertokens-core share 3 technologies: io.opentelemetry:opentelemetry-exporter-logging, OpenTelemetry, and io.opentelemetry:opentelemetry-exporter-otlp. Both are written in Java.

- [apache/flink](https://seerepo.com/r/apache/flink): Apache Flink
- [supertokens/supertokens-core](https://seerepo.com/r/supertokens/supertokens-core): Open source alternative to Auth0 / Firebase Auth / AWS Cognito

- 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.
