PostHog MCP Analytics

Analytics for MCP servers — every tool call an agent makes lands as a normal PostHog event, so you get per-tool failure and latency, the agent's own account of what it was after, and the tools it went looking for and didn't find. Beta, behind a feature preview.

Cloudflare OS

Cloudflare's internal AI productivity platform, open-sourced. Agents build "gadgets" — private per-user apps written from a prompt — and reach company systems through Gatekeepers, a capability-based permission layer.

Modal

Serverless cloud for AI and data teams — run functions, batch jobs, and GPU inference from Python or JavaScript with no infra to manage.

Latitude.sh

Global AI cloud — deploy bare metal servers and GPU clusters in seconds across 25 locations, with Kubernetes, storage, and managed databases.

Eve

Open-source agent framework from Vercel — define agents as directories of TypeScript and Markdown config and deploy them as standard Vercel projects.

Flue

TypeScript framework for building durable AI agents and workflows with no vendor lock-in — write once, deploy anywhere, run on any LLM.

Agent Registration with auth.md

Open protocol for autonomous agents to self-register for services without human intervention — a standardized auth.md file + HTTP endpoints replace OAuth and sign-up forms.

Learn Harness Engineering

A 12-lecture curriculum on building effective harnesses that enable AI agents to complete complex tasks reliably — covering architecture, state management, session continuity, and observability patterns.

How We Test TanStack AI Across 7 Providers

How TanStack AI runs 137 deterministic tests across 7 LLM providers in ~2 minutes on every PR using a mock server instead of real API calls.

Accept Markdown
