vaultwarden and neon share 5 technologies: moka, Tokio, jsonwebtoken, tracing, and log. Both are written in Rust.

- [dani-garcia/vaultwarden](https://seerepo.com/r/dani-garcia/vaultwarden): Unofficial Bitwarden compatible server written in Rust, formerly known as bitwarden_rs
- [neondatabase/neon](https://seerepo.com/r/neondatabase/neon): Neon: Serverless Postgres. We separated storage and compute to offer autoscaling, code-like database branching, and scale to zero.

- In common: moka, Tokio, jsonwebtoken, tracing, log
- Only in vaultwarden: Rocket, libsqlite3-sys, opendal, diesel, diesel_migrations, argon2, rpassword, handlebars, lettre, syslog
- Only in neon: axum, tower, asyncpg, aws-sdk-s3, pg8000, psycopg2-binary, Postgres, Redis, clickhouse-connect, AWS S3, Sentry, werkzeug, AIOHTTP, hmac, ed25519-dalek, pyjwt, jinja2, parquet, opentelemetry-semantic-conventions, prometheus, tracing-subscriber, prometheus-client, env_logger, opentelemetry-otlp, tracing-opentelemetry, psutil, tracing-appender, boto3, OpenTelemetry

- 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.
