Agenta vs Requestly

Unified Playground & Versioning

Agenta provides a centralized playground where your team can iterate on prompts and compare different models side-by-side in real-time. Every change is automatically versioned, creating a complete history of your experiments. This model-agnostic approach prevents vendor lock-in and ensures you can always use the best model for the task. Found an error in production? You can instantly save it to a test set and debug it directly within the playground, closing the feedback loop rapidly.

Systematic Evaluation Framework

Replace guesswork with evidence using Agenta's powerful evaluation system. Create a systematic process to run experiments, track results, and validate every single change before deployment. The platform supports any evaluator you need, including LLM-as-a-judge, custom code, or built-in metrics. Crucially, you can evaluate the full trace of an agent's reasoning, not just the final output, and seamlessly integrate human feedback from domain experts into your evaluation workflow.

Production Observability & Debugging

Gain complete visibility into your AI systems with comprehensive observability. Agenta traces every request, allowing you to pinpoint exact failure points when things go wrong. You and your team can annotate these traces collaboratively or gather direct feedback from end-users. With a single click, turn any problematic trace into a test case. Live, online evaluations continuously monitor performance and proactively detect regressions, ensuring your application remains reliable.

Structured Team Collaboration

Break down silos and bring product managers, domain experts, and developers into one unified workflow. Agenta provides a safe, intuitive UI for non-technical experts to edit prompts and run experiments without touching code. Everyone can participate in running evaluations and comparing results, fostering data-driven decisions. The platform offers full parity between its API and UI, ensuring seamless integration of programmatic and manual workflows into a single hub of truth.
