# OpenShell vs union

OpenShell and union share 16 technologies: net/http, axum, sqlx-postgres, sqlx, Postgres, SQLite, Tokio, tower, Ratatui, crossterm, console, tracing, tracing-subscriber, OpenTelemetry, tracing-opentelemetry, and opentelemetry-otlp. Both are written in Rust.

- [NVIDIA/OpenShell](https://seerepo.com/r/NVIDIA/OpenShell): OpenShell is the safe, private runtime for autonomous AI agents.
- [unionlabs/union](https://seerepo.com/r/unionlabs/union): The trust-minimized, zero-knowledge bridging protocol, designed for censorship resistance, extremely high security, and usage in decentralized finance.

- 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.
