# deno vs neon

deno and neon share 9 technologies: Tokio, tower, ed25519-dalek, hmac, log, tracing, tracing-opentelemetry, env_logger, and tracing-subscriber. Both are written in Rust.

- [denoland/deno](https://seerepo.com/r/denoland/deno): A modern runtime for JavaScript and TypeScript.
- [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.

## What they share and what sets them apart

- In common: Tokio, tower, ed25519-dalek, hmac, log, tracing, tracing-opentelemetry, env_logger, tracing-subscriber
- Only in deno: React, rusqlite, SQLite, wgpu, crossterm, keyring, argon2, hkdf, image, zip, plist, opentelemetry
- Only in neon: axum, asyncpg, aws-sdk-s3, pg8000, psycopg2-binary, Postgres, moka, Redis, clickhouse-connect, AWS S3, Sentry, werkzeug, AIOHTTP, jsonwebtoken, pyjwt, jinja2, parquet, opentelemetry-semantic-conventions, prometheus, prometheus-client, opentelemetry-otlp, psutil, tracing-appender, boto3, OpenTelemetry

- 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.
