With AI increasingly tucked into every cranny of the enterprise, someone has had to step up and provide the tools necessary to discover, track, and monitor all the agents and LLMs and keep them humming along in their various workflows. Thankfully, the DevOps world answered the call, building the tools to support our new overlords in an emerging subdiscipline interchangeably called “ events so that the creators can replay past behavior to track details such as token counts, spending, latency, and more. Available as a service and on-premises.
Pricing: from Arize supports this process with robust tracing and the ability to score the results for more precise iteration. Their system can track the results and tool calls from a variety of major platforms (Anthropic, AWS, OpenAI, etc.) that are initiated by the major frameworks (LangChain, LlamaIndex, DSPy, etc.). The result is insight into what data is triggering what chain of responses.
Pricing: Small free tier; has always offered solutions for tracking performance of complex systems. Now the company is drilling deeper into the challenge of detecting and ending the problems that come from models that go awry. BigPanda’s main system relies on historical data and machine learning algorithms to flag issues. Its own agent layer connects the problematic nodes and errant models while dispatching alerts to the right team members.
Pricing: “Value-based” table on watches the production workload and creates test vectors that expose how an agent may be drifting, regressing, or departing from its path. The tool automates much of the testing and scoring feedback loop so problematic patterns can be discovered and addressed. A core part of the offering is a specialized data store that can track large and sometimes deeply nested collections of tests and their results. Their approach may be summarized by one of their tag lines: “trace everything.”
Pricing: Free starter tier; specializes in staging it and testing it with a collection of use tests and regression cases. The tools are also helpful during development cycles. “Backtest your agent against reality,” their sales material promises, with a set of tools that mines the production telemetry for solid test vectors that stress every part of the agent with prompts and challenges that the agent will encounter after leaving the safety of the lab.
Pricing: On is just such a tool. The DevOps teams can track each call and add its own automated routines to examine the results, score them based on 30-plus metrics, and if desired, send it off to another LLM to evaluate the results. Agents that are constantly failing stand out. DevOps teams can also ask questions like, “Who is using this model and racking up all of the bills?” The same goes for MCP skills and other cogs in the machine.
Pricing: Free tiers for open source and small projects; to track logs across collections of services can also use it to track LLM operations, which are, of course, just another source and sink for data. It will track performance such as time to first token and offer insight into what might be causing an issue, such as lack of memory. Results then get plugged into the same cost-tracking mechanism so the bean counters can predict when the budget will run out. After all, the CFO likely doesn’t care whether the bill comes from an LLM or an old-school S3 storage bucket. Datadog integrates AI into their tools by treating these models as just another source of data.
Pricing: Small free tier with has been delivering tools that track dataflows across the full stack. Now that AIs are finding roles in many of the nodes in this complex graph, they’re expanding to track how various AI agents can interact. They want to build one platform that helps track the root cause and, often now, deploy solutions autonomously. They want to focus on being ready to support complex networks of agents that detect problems in either performance or security and then work within defined guardrails to fix them. Determining the right role for their own AI-powered agents is a key part of the product.
Pricing: offers guardrails that track performance and watch for any behavior that deviates from the ground truth. Their “LLM-as-judge” systems are distilled into compact models that can be run locally for lower costs and faster performance.
Pricing: Small free tier; Pro plans start at $50 per month with usage-based limits and costs
Standout feature: Real-time guardrails for deployed agents
Best for: Security-conscious installations that need to defend against hallucination and data leakage
Grafana Labs
Long the go-to source for now tracks performance of AI models in constellations of services. Grafana tracks the evolution of answers across the agentic network to recognize how small changes or hallucinations can spin out of control. It bills its system as “actually useful AI” and has even trademarked it. Its cloud assistant can configure and reconfigure the Grafana dash to offer the right level of observability. Its system includes AI-level analysis that can flag models that are responding quickly but offering bad answers because of problems such as model drift or context degradation.
Pricing: Basic free tier; is designed as a smart network proxy that will route all model requests while keeping solid debugging records from the data as it goes by. The data it captures can be turned into nice charts that make it easy to spot latency issues or model failures. Naturally, tracking AI spend is also a feature in much demand as bills continue to climb.
Pricing: Small free tier; works closely with OpenTelemetry to follow agents operating in production so that flaws and failure modes can be understood from log files stored efficiently with their own compression scheme. Developers can search through traces with an SQL-ish language and Laminar’s transcript view illuminates what happened. When necessary, the traces can enable developers to scroll back in time and replay the same inputs for debugging. The goal is to offer deep insights with high-level visibility of how well the agents are meeting business objectives.
Pricing: Small free tier; “Hobby” tier that adds more features at $30; traces costs, tools, and progress toward solutions for a wide collection of agents using SDKs for Python, TypeScript, Go, and Java. The OpenTelemetry-based solution watches for anomalies, issuing warnings and alerts through dashboards and communication channels such as PagerDuty. Deeper analysis can reveal issues such as topic clustering or odd patterns of failure. Coordination with agent deployment platforms such as LangGraph and deepagents ensures greater focus on successful resolution of assignments.
Pricing: Free for solo developers; offers a proxy that traces all interactions and then builds analytical dashboards for measuring metrics such as user satisfaction or model costs. One common usage is finding frequent topics and looking at the responses to ensure they deliver. When prompts aren’t perfect, Lunary lets teams iterate on the prompt text until the right answers are coming out. Its proxy structure and common API format enables Lunary to promise to work with “any LLM, any framework.”
Pricing: Free tier; AI-driven monitoring watches for golden signals that can indicate misbehavior or worse throughout the entire lifecycle. It tracks every detail of the interactions through protocols such as MCP and then makes this available to the AI engineers responsible for performance. The dashboard provides the insights necessary to watch for toxic behavior, overt bias, drift, and overblown hallucinations. Predicting and maybe even controlling the cost is also a growing role as tokenomics becomes as important as response time.
Pricing: Free tier; Pro plan fees available through website
Standout feature: Full-stack support with hundreds of integrations with other tools

Vellum
Prompt engineers spend time fussing over the details of tweaking, improving, and enhancing the words that guide the LLM. can juggle multiple options while finding a cheaper way to execute a prompt, a process the company suggests can save 60% or more.
Pricing: Open-source free tier; Pro plan starts at $35 per month
Standout feature: Focus on multi-model pipelines for true agentic solutions
