List of the Top 4 AI Agent Builders for LlamaIndex in 2025

We are excited to present an innovative platform tailored for developers to adeptly test and troubleshoot AI agents. This suite of essential tools has been crafted to spare you the effort of building them yourself. You can visually track a variety of events, such as LLM calls, tool utilization, and interactions between different agents. With the ability to effortlessly rewind and replay agent actions with accurate time stamps, you can maintain a thorough log that captures data like logs, errors, and prompt injection attempts as you move from prototype to production. Furthermore, the platform offers seamless integration with top-tier agent frameworks, ensuring a smooth experience. You will be able to monitor every token your agent encounters while managing and visualizing expenditures with real-time pricing updates. Fine-tune specialized LLMs at a significantly reduced cost, achieving potential savings of up to 25 times for completed tasks. Utilize evaluations, enhanced observability, and replays to build your next agent effectively. In just two lines of code, you can free yourself from the limitations of the terminal, choosing instead to visualize your agents' activities through the AgentOps dashboard. Once AgentOps is set up, every execution of your program is saved as a session, with all pertinent data automatically logged for your ease, promoting more efficient debugging and analysis. This all-encompassing strategy not only simplifies your development process but also significantly boosts the performance of your AI agents. With continuous updates and improvements, the platform ensures that developers stay at the forefront of AI agent technology.
