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 is building the headless CMS as an AI agent interface — a new MCP release nearly every day.
Sanity is in a sustained MCP server development sprint, shipping multiple versions per week. The MCP server now covers document creation, querying, publishing, asset management, content releases, and — as of v2.35.0 — workflow authoring and deployment by AI agents. The Studio itself is receiving stability work in parallel: Portable Text crash fixes, auth API modernization, and release management improvements. The pace of MCP iterations is more characteristic of an API startup in beta than an established CMS vendor.

Braintrust
0.0DEVOPS
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
7.5DEVOPS
Sanity is building the headless CMS as an AI agent interface — a new MCP release nearly every day.
◆ Current state
Sanity is in a sustained MCP server development sprint, shipping multiple versions per week. The MCP server now covers document creation, querying, publishing, asset management, content releases, and — as of v2.35.0 — workflow authoring and deployment by AI agents. The Studio itself is receiving stability work in parallel: Portable Text crash fixes, auth API modernization, and release management improvements. The pace of MCP iterations is more characteristic of an API startup in beta than an established CMS vendor.
◆ Where it's heading
Sanity is repositioning the MCP server as the primary integration layer for AI-driven content operations. Each release expands what an AI agent can do without a human at the Studio — from querying to publishing to now designing and deploying workflows. The guidance improvements in v2.35.1 and v2.35.2 show they're actively testing with LLM agents and fixing the failure modes that emerge. The trajectory is toward Sanity being the CMS you can fully operate through an agent.
◆ Prediction
The MCP server will extend to cover permissions and team membership management, and Sanity will likely offer a hosted agent runtime — essentially a place to run content pipelines that execute MCP tool calls on a schedule or trigger. Studio may shift to a configuration and monitoring layer for teams operating primarily through agents.
