Agenta vs Blueberry

Unified Playground & Experimentation

Agenta provides a central, model-agnostic playground where your team can safely experiment with different prompts, parameters, and models from any provider side-by-side. This eliminates the need for scattered scripts and documents. Every iteration is automatically versioned, creating a complete history of your experiments so you can track what changed, why, and its impact. Found a problematic output in production? You can instantly save it as a test case and begin debugging right in the same interface.

Systematic Evaluation Framework

Move beyond "vibe testing" with Agenta's robust evaluation system. It allows you to create a systematic process to run experiments, track results, and validate every change before deployment. The platform supports any evaluator you need—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 the evaluation workflow.

Production Observability & Debugging

When your LLM app is live, Agenta gives you clear visibility. It traces every user request, allowing you to pinpoint the exact step where failures occur. You and your team can annotate these traces to discuss issues or gather user feedback directly. With a single click, any problematic trace can be turned into a test case, closing the feedback loop. Live, online evaluations monitor performance continuously to detect regressions as they happen.

Collaborative Workflow for Whole Teams

Agenta breaks down silos by providing tools for every team member. It offers a safe, no-code UI for domain experts to edit and experiment with prompts. Product managers and experts can run evaluations and compare experiments directly from the UI, while developers work via a full-featured API. This parity between UI and API creates one central hub where everyone collaborates on experiments, versions, and debugging with real data.

Integrated Workspace

Blueberry combines the functionalities of a terminal, code editor, and preview browser, all within one workspace. This integration means you can work on code, execute commands, and see real-time previews without the hassle of switching between different applications.

AI Contextual Awareness

With Blueberry, your AI models have immediate access to your entire project context, including code, running applications, and browser views. This constant context allows for more informed responses and suggestions from AI, enhancing your productivity and reducing miscommunication.

Pinned Apps

Never lose track of essential tools again. Blueberry allows you to pin applications like GitHub, Linear, Figma, and PostHog directly within your workspace. These apps load alongside your project and share live context with your AI, streamlining your workflow.

Visual Context Features

Capture screenshots or select elements directly from the preview browser to provide your AI with visual context. This feature allows for more accurate guidance and feedback, making it easier to troubleshoot and refine your projects.

Streamlining Enterprise Chatbot Development

A financial services company is building a customer support chatbot. Their domain experts, compliance officers, and developers need to collaborate tightly. Using Agenta, they centralize prompt versions, run evaluations against regulatory compliance checklists and customer intent accuracy, and observe live interactions to quickly debug hallucinations or incorrect advice, ensuring a reliable and compliant final product.

Building and Tuning Complex AI Agents

A team is developing a multi-step research agent that searches the web, summarizes findings, and generates reports. Debugging is a nightmare when only the final output is wrong. With Agenta, they evaluate each intermediate step in the agent's reasoning chain, identify which tool call failed, and use the unified playground to iteratively fix the prompt for that specific step, dramatically improving the agent's reliability.

Managing Rapid Product Iteration with LLMs

A product team at a SaaS company uses LLMs to generate personalized email content. Marketing wants to test new tones, while engineers worry about stability. Agenta allows them to A/B test different prompt variations systematically, gather quantitative scores on engagement metrics and qualitative feedback from the sales team, and confidently deploy the winning variant with full version control and rollback capability.

Academic Research and Model Benchmarking

A research lab is comparing the performance of various open-source and proprietary LLMs on a new benchmark task. They use Agenta's model-agnostic playground to run the same prompt templates across all models, automate scoring using custom evaluation scripts, and maintain a rigorous, reproducible record of all experiments and results in one platform, streamlining their publication process.

Rapid Prototyping

Developers can quickly prototype web applications by using Blueberry's integrated features. With instant access to code editing, terminal commands, and live previews, you can iterate rapidly and bring ideas to life without losing focus.

Collaborative Development

Blueberry supports collaborative workflows by allowing teams to share their workspace. By integrating pinned apps and real-time AI assistance, team members can communicate effectively and work together to solve problems and innovate.

Learning and Experimentation

For those new to coding or exploring new technologies, Blueberry provides an ideal environment for learning. The combined editor and preview features allow learners to experiment with code while immediately seeing the results, fostering a hands-on learning experience.

Efficient Debugging

When debugging web applications, Blueberry’s all-in-one workspace simplifies the process. You can view terminal outputs, edit code, and see how changes affect the live preview—all in one place, which significantly speeds up troubleshooting.

The journey of building with large language models is often a tale of chaos. Prompts are scattered across emails and Slack threads, experiments are launched on gut feeling, and debugging a failure in production feels like searching for a needle in a haystack. This is the unpredictable reality most AI teams face, where brilliant ideas get lost in siloed workflows and unreliable deployments. Agenta emerges as the guiding path through this wilderness. It is an open-source LLMOps platform designed to be the single source of truth for teams building reliable LLM applications. Agenta transforms the fragmented process into a structured, collaborative journey. It brings developers, product managers, and domain experts together into one unified workflow, allowing them to experiment with prompts, run systematic evaluations, and observe application behavior in production—all from a centralized platform. By replacing guesswork with evidence and silos with collaboration, Agenta empowers teams to iterate quickly, validate every change, and ship AI products you can truly trust.
