Overview
Braintrust (braintrust.dev) is an AI observability and evaluation platform founded in 2023 by Ankur Goyal and headquartered in San Francisco. Built specifically for teams shipping LLM-powered products into production, it unifies trace logging, automated evaluations, prompt management, and dataset curation in a single workflow. The platform's core architecture is built on Brainstore, a purpose-built database designed for AI-trace workloads. Its 'Instrument → Observe → Annotate → Evaluate → Deploy' lifecycle lets engineering and product teams capture every prompt and tool call in production, score outputs using LLM-as-a-judge or custom code, convert failures into test cases with one click, and gate releases with CI/CD-integrated evals. Customers include Notion, Dropbox, Replit, Coursera, Cloudflare, Ramp, Stripe, Zapier, and Vercel. In February 2026 Braintrust raised an $80M Series B led by ICONIQ at an $800M valuation.
Braintrust is an end-to-end AI observability and evaluation platform that connects production trace logging with structured evaluation workflows in a single developer-centric product. It captures every LLM call, tool invocation, and agent reasoning step as hierarchical spans; scores outputs using LLM-as-a-judge, heuristic, or human annotation; manages versioned prompts; and enables teams to build regression datasets directly from production failures. Its Loop AI agent automates prompt optimization and dataset generation based on trace data, while Brainstore—a purpose-built database for AI logs—powers high-speed full-text search and querying across millions of traces. Braintrust is framework-agnostic, supports 13+ native integrations, and offers enterprise security including SOC 2 Type II, HIPAA compliance, and hybrid deployment.

Alternatives in LLM Observability Evals & Gateways6
Braintrust positions itself as the unified 'quality layer' for production AI, differentiating from point solutions by tightly coupling observability and evals in a single workflow atop Brainstore, its purpose-built AI-trace database.
- It emphasizes first-class JavaScript/TypeScript support alongside Python, end-to-end lifecycle coverage from prompt experimentation through production monitoring, and enterprise-grade security (SOC 2 Type II, HIPAA, RBAC, hybrid deployment).
- Key differentiators include Brainstore's claimed 80x faster trace search versus traditional databases, the Loop AI eval agent for automated prompt optimization, and a 'trace-to-dataset' one-click workflow that competitors typically require manual steps to replicate.
- Braintrust targets teams that want a fully managed, deeply integrated platform rather than open-source self-hosted tooling.
Reviews
Praised
- All-in-one evals and observability in one workflow
- Fast and intuitive UI
- Trace-to-dataset one-click conversion
- Strong CI/CD eval integration
- Cross-team collaboration for PMs and engineers
- Brainstore performance on large trace datasets
- Responsive to customer product feedback
- Quick time-to-value for initial setup
Criticized
- Short data retention on Starter and Pro tiers
- Customer support response times
- No open-source or self-hosted option
- Occasional platform stability and bug issues
- Enterprise pricing opacity
- Learning curve for advanced custom scorers
Public reception is positive among developer and AI engineering audiences. On G2, the platform holds a 4.5/5 rating from approximately 159 verified reviews. Users consistently praise the all-in-one combination of evals, observability, and prompt tooling; the intuitive and fast UI; the trace-to-dataset workflow; and the platform's value for cross-functional collaboration between engineers and product managers. Recurring criticisms include customer support responsiveness, short data retention windows on lower tiers, the absence of a self-hosted option, and occasional platform stability issues as the product continues to mature rapidly.
Pricing
Braintrust offers three tiers. Starter is free and includes 1 GB processed data per month, 10,000 scores, 14-day retention, and unlimited users, projects, datasets, playgrounds, and experiments; overages are $4/GB and $2.50 per 1,000 scores. Pro is $249/month with 5 GB processed data, 50,000 scores, 30-day retention, custom topics, custom charts, environments, and priority support; overages at $3/GB and $1.50 per 1,000 scores. Enterprise offers custom pricing with custom data retention and export, RBAC, custom security agreements (BAA, DPA, uptime SLA), shared Slack support, and on-premises or hosted Brainstore deployment for high-volume or privacy-sensitive workloads.
Limitations
- Short data retention windows on lower tiers (14 days on Starter, 30 days on Pro) require Enterprise for custom policies.
- No open-source or self-hosted option for cost-sensitive teams, unlike Langfuse or Arize Phoenix.
- G2 reviewers flag customer support response times and inconsistency as a recurring concern.
- Some users report occasional platform stability issues and bugs as the product matures.
- Enterprise pricing is custom/opaque with no self-serve access to higher-tier features.
- The platform's depth can introduce a learning curve for teams new to structured evals.
