Start building Contact sales Build with agents Trusted by the best AI teams Watch video Watch video Watch video Read story Watch video Inspect agent traces in real time Workflow Platform Scale Security Customers Agents fail differently than normal software. You need active observability to monitor and fix them. AI drifts and regresses silently. With patterns surfaced automatically, the best teams can evaluate against expectations and iterate continuously. Trace everything Inspect prompts, responses, and tool calls in real time Measure quality with evals Score outputs with LLMs, code, or humans Catch issues early Block bad releases before they hit production Explore the three pillars of AI observability Take the eval maturity assessment Agent observability and evals for the whole team. From engineering to product, in one platform. Observability See what actually happened in production. Inspect every agent trace and tool call, search across millions of logs, and track latency, cost, and quality in real time. Scalable agent trace ingestion Live performance monitoring Custom views and annotation Log your first trace Evals Define what good looks like before you ship. Run experiments against real datasets, compare prompts and models side-by-side, and score outputs with LLMs, code, or humans. Fast prompt engineering Flexible, versioned datasets Automated and human scoring Run your first eval Discovery Turn production signals into improvements automatically. Topics surfaces patterns in real time across task, issues, and sentiment, online scoring catches regressions, and quality gates block bad releases. Automatic pattern discovery Continuous online scoring Quality gates and alerts Discover patterns with Topics Everything you need to build smarter, faster Loop agent AI that helps you improve agents. Describe what you want to optimize, and Loop generates better prompts, scorers, and datasets automatically. Optimize your evals Custom facets Define the dimensions that matter to your business, like use case, customer segment, compliance, or tone. Topics continuously clusters every trace against them. Design your own facet Task-specific trace views Build annotation interfaces that match your team's workflow. Review support conversations differently than code generation, with no frontend work required. Build custom views Trace to dataset Turn production traces into eval datasets with one click. Build regression tests from real failures and edge cases, not synthetic examples. Explore datasets MCP Query logs, run evals, and update prompts directly from your IDE. Braintrust's MCP server connects your coding agent to your AI stack. Set up MCP Framework agnostic Works with any stack you're already using. No framework lock-in, no rewrites, no vendor dependencies to manage. View all integrations Native SDKs SDKs for Python, TypeScript, Go, Ruby, C#, and more. Start tracing production agents with just a few lines of code. Read SDK docs Brainstore, the database built for AI data at scale. Designed for complex agent traces. Agent traces are large and nested. Traditional databases can't handle the complexity. Brainstore is designed specifically for agent observability so you can query millions of traces quickly.
