What is Braintrust?

Braintrust is making LLM observability painless to adopt — auto-instrumentation across every major language.

Braintrust's recent run is dominated by zero-code instrumentation work: Python, Ruby, Go, and TypeScript all gained auto-instrumentation, and topics automatically classify logs without manual schema work. The product is also deepening agent-tooling integrations with Claude Code and Temporal, and adding operational features like trace translation, member session history, and dataset tagging. Monthly SDK releases continue with steady model-coverage updates.

What is Sanity?

Sanity's MCP server hits v2.33 with safer publishing guards as Studio bug-fix cadence accelerates

Sanity is running two parallel tracks simultaneously: Studio (v6.14.x) is receiving rapid bug-fix releases targeting real-world pain — Portable Text data-loss risks, appearance theming inconsistencies, popover UX regressions. At the same time, the MCP server is iterating weekly from v2.31 to v2.33, adding revision guards for safer publishing, distributed-tracing auth fixes, and token-efficient query responses. The combined picture is a team hardening both the human-facing editor and the AI-tool-facing API interface.

Braintrust vs Sanity: editorial side-by-side

B0.0

Braintrust is making LLM observability painless to adopt — auto-instrumentation across every major language.

◆ Current state

Braintrust's recent run is dominated by zero-code instrumentation work: Python, Ruby, Go, and TypeScript all gained auto-instrumentation, and topics automatically classify logs without manual schema work. The product is also deepening agent-tooling integrations with Claude Code and Temporal, and adding operational features like trace translation, member session history, and dataset tagging. Monthly SDK releases continue with steady model-coverage updates.

◆ Where it's heading

The trajectory is unambiguous: Braintrust is making LLM evals and observability frictionless to start with — drop a SDK, get traces — and then deeper to live in for engineers running multi-step agents. Auto-instrumentation across four languages plus structured topic-classification of logs lowers the start-up cost. The Claude Code and Temporal integrations show Braintrust is positioning to observe long-running agentic workflows specifically, not just one-shot chat completions.

◆ Prediction

Expect more agent-framework integrations (LangGraph, CrewAI, OpenAI Agents SDK if not already covered) and richer agent-aware UI — span trees that group reasoning steps, replay-from-step, automatic eval generation from production traces. The member-activity work hints at SOC 2/enterprise compliance pressure that will shape additional governance features.

Sanity's MCP server hits v2.33 with safer publishing guards as Studio bug-fix cadence accelerates

◆ Current state

Sanity is running two parallel tracks simultaneously: Studio (v6.14.x) is receiving rapid bug-fix releases targeting real-world pain — Portable Text data-loss risks, appearance theming inconsistencies, popover UX regressions. At the same time, the MCP server is iterating weekly from v2.31 to v2.33, adding revision guards for safer publishing, distributed-tracing auth fixes, and token-efficient query responses. The combined picture is a team hardening both the human-facing editor and the AI-tool-facing API interface.

◆ Where it's heading

Sanity is building the MCP server into a production-grade write interface for AI agents. The `ifRevisionId` guard in v2.33 — which causes publishing to fail if a draft changed since the caller read it — is the kind of concurrency safety needed before AI agents can reliably edit live content. Studio stability work is catching up after a period of fast feature shipping. Expect MCP tool coverage to broaden and the auth/schema layers to continue hardening for enterprise-scale deployments.

◆ Prediction

The next MCP server release will likely add more write-path safety features — document locking or conflict detection. Studio v6.15 will address remaining edge cases exposed by the MCP surface's broader read/write coverage.
