★ 788free-ai-tools
Curated list of free and low cost AI tools, LLM APIs, IDEs, agents, and infrastructure for building real AI apps
AI channelLLM apps 
Open-source LLM apps and frameworks
This is the broadest group: chat interfaces, SDKs and frameworks, prompt and evaluation tools, and applications built on large language models. Many work with models from several providers, and some can run models on your own hardware.
How to choose
For anything you plan to ship, check three facts first: the licence, because some popular projects restrict commercial use; whether it supports the model provider you already use; and whether it is still maintained. The At a glance box on every project page answers the licence and maintenance questions from GitHub data.
