Feature Comparison

Blueberry

Integrated Workspace

Blueberry combines a terminal, code editor, and preview browser into one cohesive workspace. This integration allows developers to manage their projects without the need to switch between different applications, enhancing focus and productivity.

Real-Time AI Context

With Blueberry's MCP server, users can connect AI models like Claude and Codex directly to their workspace. This feature ensures that the AI has full context of the project, including open files and terminal outputs, enabling smarter and more context-aware interactions.

Pinned Apps

Developers can dock essential applications such as GitHub, Linear, Figma, and PostHog within the Blueberry workspace. These pinned apps load alongside the project, sharing live context with the AI, which further streamlines the development process.

Visual Context Tools

Blueberry provides features like screenshot capture and element selection directly from the preview browser. This allows developers to give their AI visual context, enhancing the effectiveness of AI interactions and feedback during the development process.

Fallom

End-to-End LLM Tracing

Fallom provides complete, real-time observability for every LLM call and AI agent interaction. It captures the full context of each operation, including the exact input prompts, model-generated outputs, all intermediate tool and function calls with their arguments and results, token consumption, latency breakdowns, and precise cost data. This granular, waterfall-style tracing is essential for understanding complex, multi-step workflows, diagnosing failures, and identifying performance bottlenecks that simple logs cannot reveal.

Enterprise Compliance & Audit Trails

The platform is built from the ground up to support the stringent requirements of regulated industries. Fallom automatically generates immutable, detailed audit trails for every AI interaction, providing the necessary documentation for compliance with frameworks like the EU AI Act, SOC 2, and GDPR. Features include comprehensive input/output logging, model versioning tracking, user consent recording, and configurable privacy modes that allow for metadata-only logging to protect sensitive data while maintaining full telemetry.

Cost Attribution & Spend Management

Fallom delivers unparalleled transparency into AI operational costs. It automatically attributes spend across multiple dimensions, including per model, per API call, per user, per team, or per customer. This allows for accurate budgeting, internal chargebacks, and identifying cost-optimization opportunities. Real-time dashboards and visualizations help teams monitor their monthly burn, compare model costs, and control unpredictable expenses before they escalate.

Model Management & A/B Testing

The platform enables safe and data-driven model evolution. Teams can conduct live A/B tests by splitting traffic between different models or prompt versions, comparing their performance on key metrics like cost, latency, and quality evaluations. Coupled with a integrated Prompt Store for version control, this allows organizations to systematically roll out improvements, validate new models in production, and instantly deploy winning configurations with confidence.

Use Cases

Blueberry

Streamlined Development

Blueberry is ideal for developers looking to streamline their workflow. By integrating all necessary tools into one workspace, developers can focus on coding and testing their web applications without interruptions.

Enhanced Collaboration

With pinned apps and live context sharing, teams can collaborate more effectively. Developers can work alongside designers and project managers within the same environment, ensuring that everyone is on the same page.

AI-Assisted Programming

Blueberry's real-time AI context allows for enhanced programming assistance. Developers can ask questions to their AI models while viewing their code and terminal output, leading to quicker problem-solving and more efficient coding.

Responsive Design Testing

The built-in preview browser enables developers to test their applications across various devices, including desktop, tablet, and mobile. This feature ensures that applications are responsive and user-friendly before deployment.

Fallom

Debugging Complex AI Agent Workflows

When a multi-step AI agent—involving sequential LLM calls, database queries, and API tool usage—fails or behaves unexpectedly, traditional logging is insufficient. Fallom’s end-to-end tracing allows developers to visually follow the entire execution path, inspect the state at each step, see the exact inputs and outputs of every tool call, and pinpoint precisely where and why an error occurred, drastically reducing mean time to resolution (MTTR).

Ensuring Regulatory Compliance for AI Products

For companies operating in finance, healthcare, or any sector bound by regulations like the EU AI Act, demonstrating accountability is non-negotiable. Fallom provides the necessary audit trail, documenting every AI decision, the model version used, user interactions, and data handling. This creates a verifiable record that proves due diligence, supports compliance audits, and helps build trustworthy, transparent AI systems.

Optimizing AI Performance and Cost Efficiency

Organizations scaling their AI usage often face ballooning, opaque costs and latency issues. Fallom’s detailed metrics allow teams to analyze which models, prompts, or users are driving the highest spend and latency. Engineers can use this data to optimize prompts, switch to more cost-effective models for certain tasks, cache frequent responses, and right-size their AI infrastructure, leading to direct improvements in unit economics and user experience.

Managing Production AI Rollouts and Experiments

Safely introducing a new LLM model or a major prompt update into a live application is risky. Fallom’s A/B testing and evaluation framework allows product teams to roll out changes to a small percentage of traffic, compare the new version’s performance against the baseline on real-world data, and monitor for regressions in accuracy or hallucinations before committing to a full deployment, minimizing operational risk.

Fallom FAQ

How does Fallom differ from traditional application monitoring tools?

Traditional Application Performance Monitoring (APM) tools are built for conventional software, focusing on metrics like CPU usage, HTTP request latency, and database queries. They lack the native concepts required for AI: prompts, completions, token usage, model costs, and multi-step agent reasoning. Fallom is purpose-built for the AI stack, providing semantic understanding of LLM calls, tool executions, and the unique cost and compliance dimensions of generative AI, offering insights that generic tools cannot.

Is my data secure and private with Fallom?

Yes, Fallom is designed with enterprise-grade security and privacy controls. It offers a configurable Privacy Mode that allows you to disable full content capture for sensitive interactions, logging only metadata (like timings and token counts) while still providing crucial observability. Data is encrypted in transit and at rest, and the platform's compliance features, including audit trails and access controls, help you meet stringent data protection standards like GDPR.

How difficult is it to integrate Fallom into my existing AI application?

Integration is designed to be straightforward and fast. Fallom provides a unified SDK based on the OpenTelemetry standard. For most applications, developers can instrument their LLM calls and tool usage in under five minutes. The platform works with all major model providers (OpenAI, Anthropic, Google, etc.) and AI frameworks, ensuring there is no vendor lock-in and you can maintain your existing AI infrastructure.

Can Fallom help me reduce my overall LLM API costs?

Absolutely. Cost optimization is a core strength. By providing detailed, per-call cost attribution, Fallom helps you identify the most expensive operations, users, or model choices. You can analyze patterns, A/B test more cost-effective models for specific tasks, optimize inefficient prompts that consume excessive tokens, and set up alerts for unexpected spend spikes, enabling proactive cost management and significant savings.
