Choosing the right LLM observability and evaluation platform comes down to what matters most to your team.
Arize AI's strength lies in its ML monitoring heritage—if you're already using Arize for traditional ML models, adding LLM observability to the same platform has obvious appeal. But that heritage also shapes its limitations: the platform is built for engineers running technical analysis, not cross-functional teams iterating on AI quality together.
Confident AI takes a different approach. It's built for teams where PMs run evaluation cycles without engineering bottlenecks, where QA teams own regression testing, and where domain experts provide feedback directly on production traces—all without writing code.
In this guide, we'll break down the differences across features, pricing, and use cases to help you decide.
How is Confident AI Different?
1. Non-technical teams can run evaluations without engineering
In most AI teams, every evaluation cycle requires engineering involvement—setting up test scripts, configuring endpoints, running code. This makes engineers the bottleneck for every AI quality decision.
Confident AI removes this bottleneck with AI connections. PMs, QA teams, and domain experts can evaluate your actual AI application directly from the platform—no code, no engineering tickets, no waiting.
PMs run full evaluation cycles on your production app independently
QA teams trigger regression tests against real endpoints on their own schedule
Domain experts validate behavior without asking engineering to "run a quick test"
When the people closest to your users can test the real thing themselves, AI quality stops being blocked on engineering capacity.
2. Simulations turn hours of manual testing into minutes
Evaluating chatbots and conversational agents means generating conversations to test. Without automation, that's 2-3 hours of manual prompting per evaluation—just to create the data you'll actually score.
Arize AI doesn't offer multi-turn simulations. Confident AI does.
Define a scenario, and the platform generates realistic multi-turn conversations automatically. What took hours now takes minutes—easily 30x time saved per evaluation cycle for teams testing conversational AI at scale.
3. Built for the whole team, not just engineers
Arize AI's ML monitoring roots show in its engineering-centric design. The UX assumes technical comfort, and workflows are built for data science personas.
This creates friction the moment anyone outside engineering needs to participate:
Product managers reviewing evaluation results
Domain experts flagging problematic outputs
QA teams uploading test datasets
Confident AI is designed so these teams own their part of the AI quality process—upload CSVs, run evaluations, annotate traces, curate datasets—all from a UI built for clarity, not technical gatekeeping.

Pricing
Both platforms offer paid tiers, but with different pricing philosophies.
Confident AI uses a transparent pricing model based on usage and user seats. Costs are predictable—measured by trace count rather than tokens or storage—so you can forecast spend before you scale.
Arize AI's pricing reflects its enterprise ML monitoring roots, with custom pricing for most plans. For teams prioritizing budget transparency, this can make cost planning difficult.
But pricing tells only part of the story. Confident AI's pricing reflects what you're getting:
Multi-turn simulations for testing conversational agents, bringing hours down to minutes per multi-turn evaluation, easily 30x in time saved
Features for cross-functional teams—non-technical teams can easily test multi-prompt AI systems, instead of making engineers a bottleneck in the AI quality assurance process
Red teaming—secure testing is something everyone eventually needs, don't double-pay for vendors on this
Enterprise support—work sessions to come up with the optimal evals strategy with the authors of DeepEval ensures you get the most ROI out of observability
The trade-off is straightforward: Arize AI has deep ML monitoring roots. Confident AI has deeper LLM evaluation capabilities. Choose based on whether you need traditional ML observability or comprehensive AI quality infrastructure.

Why Confident AI is the Best Arize AI Alternative
Although both are feature-rich LLM observability platforms, Confident AI stands out because it centralizes everything related to AI quality—observability, evaluations, simulations, and red teaming—while offering a UI intuitive enough for non-technical teams to use.
On paper, the two platforms may look similar. In practice, Confident AI unlocks more ROI by:
Empowering non-technical team members to run an end-to-end, AI app iteration cycle without touching a line of code, instead of single-prompt testing
Including multi-turn simulations that save hours of manual testing for conversational use cases
Offering red teaming out of the box—security testing for AI apps that every production system eventually needs
Delivering more functionality across the board for teams serious about AI quality
Arize AI is a strong choice if deep ML model monitoring and technical analysis are your priorities. But if you want industry-standard evals baked into your observability stack, don't want to stitch together separate tools for simulations and red teaming, and need a platform accessible to your entire team—Confident AI delivers more value.
Getting started is easy, and the best way to see the difference is to try it yourself for free.
When Arize AI Might Be a Better Fit
Arize AI excels in specific scenarios where Confident AI may not be the optimal fit:
Traditional ML model monitoring: If your organization has existing ML models beyond LLMs that need monitoring, Arize's heritage in ML observability means you get a unified platform for both traditional ML and LLM monitoring.
Engineering-only workflows: If your AI quality process is purely engineering-driven with no need for cross-functional collaboration, Arize's technical-first interface may suit your team's preferences.
Deep technical analysis: For data science teams comfortable with technical concepts and optimizing for deep analysis over quick iteration, Arize's engineering-centric design may feel more natural.
The bottom line: Both platforms solve real LLM observability problems. Choose Arize AI if you need unified ML monitoring across traditional and LLM models, or if your workflow is purely engineering-driven. Choose Confident AI if you need evaluation depth, multi-turn support, or a platform designed for your entire team—not just engineers.
