Fallom

End-to-End LLM Tracing & Live Dashboard

Gain real-time, granular visibility into every AI interaction. Fallom's live dashboard shows a streaming feed of all LLM calls, capturing the full context: the exact input prompt, the model used, token counts, latency, and calculated cost. You can click into any trace to see the complete chain, including intermediate steps and tool calls. This instant, detailed observability is critical for spotting anomalies, understanding user behavior, and ensuring your AI features are performing as expected in the wild.

Enterprise Compliance & Audit Trails

Navigate the complex landscape of AI regulation with confidence. Fallom is built for compliance, offering immutable, complete audit trails of every LLM interaction. This includes full input/output logging, model versioning, and user consent tracking—essential for adhering to the EU AI Act, GDPR, and SOC 2 requirements. A dedicated Privacy Mode allows you to disable content capture for sensitive data, maintaining full telemetry while protecting user privacy and confidential information.

Advanced Cost Attribution & Analytics

Take control of your spiraling AI spend. Fallom automatically attributes costs across every dimension: per model, per user, per team, and per customer. The platform provides clear dashboards and breakdowns, showing exactly where your budget is going. This enables precise budgeting, internal chargeback, and data-driven decisions on model selection, helping you optimize for both cost and performance without any financial blind spots.

Timing Waterfalls & Tool Call Visibility

Debug the performance of multi-step AI agents with surgical precision. Fallom's timing waterfall visualizations break down the latency of each step in an agent's workflow, instantly pinpointing whether delays are in LLM calls, tool executions (like database queries or API calls), or your own code. Combined with full visibility into every tool call's arguments and results, you can quickly identify and resolve bottlenecks that impact user experience.

Use Cases

Enhancing Code Quality for Startups

Startups often operate under tight deadlines and limited resources. diffray helps these teams maintain high code quality by providing accurate, actionable feedback on code changes, enabling faster iterations and reducing the risk of critical bugs in production.

Streamlining Code Reviews for Large Teams

In larger teams, code reviews can become bottlenecks. diffray accelerates the review process by minimizing noise and highlighting genuine issues, allowing teams to review code more efficiently and effectively, ultimately speeding up the development lifecycle.

Ensuring Compliance in Regulated Industries

For teams working in regulated industries, ensuring code compliance with established standards is crucial. diffray's specialized agents focus on security and best practices, helping teams identify and rectify compliance issues before they become costly problems.

Facilitating Continuous Integration and Deployment

diffray fits perfectly into CI/CD pipelines by providing real-time feedback on code changes. This ensures that code is consistently reviewed for quality before deployment, reducing the likelihood of introducing bugs into production environments and maintaining software reliability.

Fallom

Monitoring and Debugging Production AI Agents

When your customer-facing AI agent starts behaving oddly or timing out, you need answers fast. Fallom provides the complete picture, allowing you to trace a user's failed session end-to-end. See the exact prompts that led to an error, inspect the arguments passed to a faulty tool call, and analyze latency waterfalls to find the slow step. This turns hours of guesswork into minutes of targeted debugging, ensuring high reliability for your AI-powered features.

Ensuring Regulatory Compliance for AI Products

For companies in finance, healthcare, or any regulated industry, deploying AI comes with heavy compliance burdens. Fallom acts as your audit engine, automatically generating the required logs for every LLM interaction. You can prove which model version generated a specific output, demonstrate that user consent was captured, and maintain privacy-mode logs for sensitive operations, making audits for the EU AI Act or GDPR a streamlined process.

Controlling and Optimizing LLM Spend

With AI costs becoming a major line item, finance and engineering teams need transparency. Fallom answers critical questions: Is Team A's experimental feature burning budget on GPT-4? Which customer is the most expensive to serve? By providing detailed, attribute-level cost reporting, Fallom enables showback/chargeback models, helps teams choose cost-effective models for specific tasks, and identifies wasteful patterns before they impact the bottom line.

Performance Optimization and Model A/B Testing

Before rolling out a new, faster model like Claude 3.5 Sonnet, you need confidence it won't break things. Fallom's built-in A/B testing framework lets you safely split traffic between models, comparing their performance, cost, and output quality (via integrated evaluations) in real-time. Combined with timing waterfalls, you can validate latency improvements and switch traffic with confidence, ensuring continuous performance enhancement.
