PraisonAI
Python framework for autonomous, self-improving multi-agent workforces.
PraisonAI is a multi-agent framework for building autonomous agents that research, plan, code and execute tasks, from a single agent up to multi-agent teams that hand off work and verify results. The lightweight praisonaiagents core SDK creates an agent in a few lines of Python, and the project advertises built-in memory, RAG and support for 100+ LLMs. Documented use cases include research, code generation, data pipelines, workflow automation and support bots on Telegram, Discord and Slack.
