Captures execution traces from AI applications via native SDKs (Python, TypeScript, Go, Ruby, C#) and stores them in Braintrust's proprietary Brainstore database optimized for nested, large AI traces. Enables real-time inspection of prompts, responses, tool calls, latency, and cost metrics with full-text search across millions of traces. Implements scalable trace ingestion with custom column definitions and saved table views without requiring frontend engineering.
Unique: Brainstore database is purpose-built for AI observability with optimized indexing for nested trace structures and full-text search, rather than adapting generic time-series or logging databases. Supports custom trace views without frontend work, enabling non-engineers to define monitoring dashboards.
vs alternatives: Faster querying of complex nested traces than generic observability platforms (Datadog, New Relic) because Brainstore indexes AI-specific structures; cheaper than cloud logging services for AI-heavy workloads due to per-GB pricing model rather than per-event.
Provides a framework for evaluating AI outputs against datasets using three scoring methods: LLM-as-judge (using configurable LLM models), code-based scorers (custom Python/TypeScript functions), and human annotation. Runs evaluations across production traces or custom datasets, compares results across prompt/model variants, and generates comparison reports. Integrates with CI/CD pipelines to block releases when quality metrics regress below thresholds.
Unique: Unified evaluation framework supporting three orthogonal scoring methods (LLM, code, human) in a single system, allowing teams to mix scoring approaches within a single evaluation run. Integrates evaluation directly into CI/CD pipelines with automatic release blocking, rather than treating evaluation as a separate post-deployment analysis step.
vs alternatives: More integrated than standalone evaluation tools (like Ragas or LangSmith evals) because it connects evaluation results directly to CI/CD gates and production traces, enabling closed-loop quality monitoring; cheaper than hiring QA teams for manual evaluation through LLM-as-judge automation.
Implements tiered data retention policies with automatic archival to S3 for long-term storage. Starter tier retains traces for 14 days, Pro tier for 30 days, Enterprise tier with custom retention. Enables export of traces and datasets to S3 for external analysis, compliance archival, or migration to other platforms. Supports per-project retention policies on Enterprise tier.
Unique: Implements tiered retention with automatic S3 export, enabling long-term data archival without requiring manual export workflows. Per-project retention policies on Enterprise tier enable fine-grained control over data lifecycle.
vs alternatives: More flexible than fixed retention periods because data can be archived to S3 for indefinite storage; more portable than proprietary retention because exported data can be analyzed in external tools.
Implements full-text search across all trace data with optimized indexing for AI-specific structures (prompts, responses, tool calls). Provides 'Topics' feature for automatic pattern discovery and classification of similar traces without manual rule definition. Enables deep search across millions of traces with low latency, supporting complex queries across custom dimensions and metadata.
Unique: Brainstore database is optimized for full-text search across nested AI trace structures, enabling fast queries across millions of traces. Topics feature provides automatic pattern discovery without requiring manual rule definition or clustering configuration.
vs alternatives: Faster than generic full-text search because Brainstore indexes AI-specific structures; more automated than manual pattern analysis because Topics automatically classifies similar traces.
Provides SOC 2 Type II, GDPR, and HIPAA compliance certifications with Business Associate Agreement (BAA) available on Enterprise tier. Implements data governance controls including encryption, access logging, and data residency options. Supports on-premises or hosted deployment for Enterprise customers requiring data sovereignty.
Unique: Provides multiple compliance certifications (SOC 2, GDPR, HIPAA) as standard features rather than add-ons, treating compliance as a core platform concern. On-premises deployment option enables data sovereignty for regulated industries.
vs alternatives: More compliant than generic observability platforms because it's specifically designed for regulated industries; more flexible than cloud-only solutions because on-premises deployment is available for Enterprise customers.
Provides a prompt playground and version control system for managing prompt iterations with automatic versioning, comparison, and A/B testing capabilities. Stores prompts in Braintrust with full history, enables side-by-side comparison of prompt variants, and supports running experiments to measure performance differences across versions. Integrates with IDE via MCP (Model Context Protocol) for prompt updates without leaving the editor.
Unique: Treats prompts as first-class versioned artifacts with full history and comparison capabilities, rather than embedding them in code. MCP integration enables prompt updates from IDE without context switching, bridging the gap between prompt engineering and software development workflows.
vs alternatives: More integrated than prompt management in LangSmith or LlamaIndex because it connects prompts directly to evaluation results and CI/CD gates; faster iteration than code-based prompt management because changes don't require redeployment.
Enables creation and management of evaluation datasets with automatic conversion from production traces. Allows teams to capture real-world examples from production, label them with expected outputs or quality criteria, and build evaluation datasets without manual data collection. Supports dataset versioning, filtering, and export for use in evaluations and experiments.
Unique: Automatically converts production traces into evaluation datasets, eliminating manual data collection and ensuring evaluation data is representative of real-world usage patterns. Integrates dataset creation directly into the observability workflow rather than treating it as a separate data engineering task.
vs alternatives: More efficient than manual dataset creation because it mines real production examples; more representative than synthetic datasets because it captures actual user inputs and edge cases encountered in production.
Monitors AI application quality metrics in production and automatically detects regressions when performance drops below configured thresholds. Implements pattern discovery via 'Topics' feature to classify and group similar traces, enabling identification of systematic issues. Supports custom alerts and automations triggered by quality degradation, latency increases, or cost anomalies. Integrates with CI/CD to block releases when regressions are detected.
Unique: Integrates regression detection directly into CI/CD pipelines to block releases before they reach production, rather than detecting regressions post-deployment. Topics feature provides automatic pattern discovery without requiring manual rule definition, enabling discovery of systematic issues.
vs alternatives: More proactive than traditional monitoring because it prevents bad releases rather than detecting them after deployment; more automated than manual QA review because it uses evaluation metrics to make release decisions.
