As generative AI evolves, the rise of agentic AI—autonomous systems that understand, plan, and act using large language models (LLMs)—is rapidly reshaping how developers and data professionals think about automation. These agents aren’t just chatbots; they’re autonomous, tool-using entities capable of executing multi-step tasks, reasoning over data, and adapting over time.

At their core, agentic systems combine several components: an LLM (the “brain”), memory for persistent context, tools for interacting with data and APIs, and planning mechanisms that drive task execution. The open-source ecosystem has embraced this paradigm, delivering frameworks and platforms that are transparent, extensible, and optimized for innovation.

Open-source tools allow for:

• Transparency and customization of agent behavior and integrations.
• Community-driven development, accelerating feature rollouts, and troubleshooting.
• Affordability and accessibility, reducing friction for adoption and experimentation.
• Flexible deployment across local, cloud, or hybrid environments.

Together, we’re going to explore the major open-source agentic tools across foundational frameworks, orchestration layers, visual platforms, and observability stacks—empowering data professionals to build and scale AI-driven workflows.
