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 now explains failed validations and stops skipping them.

Sanity made Context Knowledge Bases generally available on November 10, letting agents read datasets, websites and files over MCP. The days since have been follow-up: MCP server 2.46.1 and 2.46.2 return stable error codes, explain incomplete validations and stop writes from skipping schema checks, while the console now shows when each robot token was last used. Media Library made PDF previews zoomable and folder counts in big libraries about seven times faster.

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.

6.3

Sanity's MCP server now explains failed validations and stops skipping them.

◆ Current state

Sanity made Context Knowledge Bases generally available on November 10, letting agents read datasets, websites and files over MCP. The days since have been follow-up: MCP server 2.46.1 and 2.46.2 return stable error codes, explain incomplete validations and stop writes from skipping schema checks, while the console now shows when each robot token was last used. Media Library made PDF previews zoomable and folder counts in big libraries about seven times faster.

◆ Where it's heading

Sanity is making the agent-facing parts dependable: the MCP server is getting the error codes and validation rules a production client needs. Access visibility for tokens and members follows the same push to let teams audit what automated clients do.

◆ Prediction

Expect more MCP server point releases around validation and Knowledge Base commands, and more usage data on tokens and agents in the console.
