Fallom
Debugging Complex AI Agent Workflows
When a customer-facing agent fails to book a flight correctly, traditional logging offers only fragments of the story. Fallom allows developers to replay the entire agent session, examining the exact prompts, the data returned from each tool call (like flight search APIs), and the LLM's reasoning at each step. This complete context transforms debugging from a guessing game into a precise, efficient process, dramatically reducing mean time to resolution for intricate AI issues.
Implementing Transparent AI Cost Management
For a SaaS company embedding AI features, uncontrolled costs can quickly derail profitability. Fallom enables finance and engineering leaders to see precisely how much each product feature, customer segment, or internal project is spending on AI. This allows for accurate showback/chargeback models, informed decisions on pricing tiers, and identification of optimization opportunities, such as switching to a more cost-effective model for certain tasks without degrading user experience.
Ensuring Regulatory Compliance for AI Deployments
A healthcare or financial services firm deploying AI assistants must demonstrate strict adherence to data privacy and operational transparency regulations. Fallom provides the verifiable audit trail required, logging every interaction with user context, model versions used, and data processed. Its privacy controls ensure sensitive information can be protected, giving compliance officers the evidence needed to pass audits and build trust with users and regulators.
Optimizing Model Performance & A/B Testing
Choosing the right LLM is critical for application quality and cost. Fallom facilitates robust A/B testing by allowing teams to safely split traffic between different models or prompt versions. You can then compare their performance in real-time across key metrics like accuracy, latency, and cost per call directly within the platform. This data-driven approach takes the guesswork out of model selection and prompt engineering, ensuring you confidently deploy the best-performing configuration.

Fallom FAQ
How does Fallom integrate with my existing application?
Fallom is built on the open standard OpenTelemetry (OTEL), making integration remarkably straightforward. You simply install a single, lightweight SDK into your application code. This SDK automatically instruments your LLM calls—whether you use OpenAI, Anthropic, Google, or other providers—and sends the rich tracing data to the Fallom platform. This means no vendor lock-in and a setup process that can be completed in under five minutes, with no changes to your core application logic.
Can Fallom handle sensitive or private data?
Absolutely. Fallom is designed with enterprise-grade security and privacy controls. It offers a configurable "Privacy Mode" where you can choose to redact specific data fields, log only transaction metadata (like timestamps and token counts), or disable content capture entirely for sensitive environments. This allows you to maintain full observability over system performance and costs while ensuring user data and confidential information are protected according to your policies.
What makes Fallom different from traditional APM tools?
Traditional Application Performance Monitoring (APM) tools are built for conventional software, struggling to interpret the non-deterministic, language-heavy nature of LLM operations. Fallom is AI-native, meaning it understands concepts unique to this domain: it traces semantic prompts and completions, visualizes tool-call sequences, attributes costs per token, and evaluates output quality. It provides the specific context and metrics that AI engineers need, which generic APM tools simply cannot surface.
How does Fallom help with testing and quality assurance?
Fallom includes capabilities for running evaluations on your LLM outputs. You can define custom checks for accuracy, relevance, hallucination rates, or other metrics and run them against sampled or all production traces. This allows you to catch regressions in model performance or prompt effectiveness before they widely impact users. Coupled with its Prompt Store for versioning and A/B testing, it creates a robust framework for continuous improvement of your AI's quality.
