# neon vs llama_index

neon and llama_index share 12 technologies: asyncpg, psycopg2-binary, Redis, clickhouse-connect, AIOHTTP, pyjwt, jinja2, opentelemetry-semantic-conventions, prometheus-client, psutil, boto3, and OpenTelemetry. neon is written in Rust and llama_index in Python.

- [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.
- [run-llama/llama_index](https://seerepo.com/r/run-llama/llama_index): LlamaIndex is the document processing platform for AI

- 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.
