30 seconds of code (Chalarangelo/30-seconds-of-code) is a GitHub repository that points to a collection of coding articles at 30secondsofcode.org, maintained by Angelos Chalaris. Each article pairs a code snippet with an explanation and an example, and the snippets themselves are licensed CC-BY-4.0; the project isn't taking new content submissions right now, per its README.

DeerFlow is ByteDance's open-source super agent harness — a Gateway API, sandbox layer, and LangGraph-backed checkpoint store for running multi-agent AI tasks that take minutes to hours rather than seconds. Version 2.0 is a full rewrite of the original Deep Research framework, adding a setup wizard, broader LLM provider support (including CLI-backed Codex and Claude Code auth), and a documented multi-worker production path built on Postgres and Redis.

Your own personal AI assistant. Any OS. Any Platform. The lobster way. 🦞

ECC is an MIT-licensed system from affaan-m/ECC that installs into AI coding agent harnesses such as Claude Code, Codex, and several others, adding skills, specialized agents, persistent memory, and AgentShield security scanning around whatever large language model the harness already runs. The README positions it as developer productivity tooling for LLM agent development and agent performance tuning rather than a code generation tool itself, composing around whichever model the harness already calls.
