React Doctor is a one-command static analysis tool that scans your React codebase and outputs a health score from 0 to 100 alongside a detailed diagnostic report. Run `npx react-doctor@latest .` and it identifies anti-patterns across six dimensions: state & effects, performance, architecture, security, accessibility, and dead code. It auto-detects your framework (Next.js, Vite, React Native) and React version, adjusting rules accordingly. The tool was built by Million.co—the team behind the Million.js performance library—and is clearly aimed at the post-AI-coding era. Its killer feature might be the "agent instruction installation" mode: it teaches Claude Code, Cursor, and other coding agents the project's quality rules, so future agent-written code conforms to them before React Doctor even runs. It also integrates with GitHub Actions and can post PR comments with health score diffs, making it easy to catch regressions before merge. With 8.7K stars and one of today's fastest-growing GitHub repos, the timing is perfect. Developers are increasingly shipping agent-written React code they didn't review line by line, and React Doctor fills the gap. It's MIT-licensed, requires no config to get started, and the CI integration takes about five minutes to set up.

Voker (YC S24) is an analytics platform that does for AI agents what Mixpanel did for web products — transforms raw agent conversations into structured, queryable insights without requiring a data engineering team. It auto-classifies user intents, detects when agents fail to resolve requests, surfaces knowledge gaps, and tracks performance regressions when you update your prompts. The platform integrates with OpenAI, Anthropic, Gemini, LangChain, CrewAI, and Vercel AI SDK via lightweight Python and TypeScript SDKs. Non-technical team members — PMs, analysts, support leads — can query conversation timelines, track satisfaction trends, and measure business impact without needing SQL or engineering support. The free tier covers 2,000 events/month, which is generous for small projects. Paid plans start at $80/month for 20K events. The core pain point is real: most teams today do spot-checks by hand to debug agent behavior at scale, which doesn't scale past a few hundred conversations. Voker automates that loop.
Reviewer scorecard
“The GitHub Actions integration with PR health score diffs is the feature I didn't know I needed. Installing it took three minutes and immediately flagged three useEffect anti-patterns Cursor introduced last week.”
“The pain point is totally real — debugging agent behavior in production today is a nightmare of manually reading transcripts. Intent detection + resolution tracking as first-class primitives is exactly what's missing from the current toolchain. The SDK integration is clean.”
“Static analysis for React isn't new—ESLint with react-hooks/exhaustive-deps, Biome, and others already catch most of these patterns. The 'health score' framing may encourage false confidence if teams focus on the number rather than the individual findings.”
“The 2,000 event free tier sounds decent until you realize a mid-size chatbot burns through that in a day. And at $400/month for 2M events, you're paying a premium for what's essentially LLM-powered log analysis. Full-featured observability tools like LangSmith and Langfuse are closing this gap fast.”
“Teaching agents the rules upfront rather than fixing their output afterward is the right architectural direction. As agent-written code becomes the norm, tools that close the feedback loop at the prompt level will be as important as compilers.”
“Agent analytics is going to be a massive category — every company deploying autonomous AI will need to instrument it like software. Voker is positioning early in a space that'll see consolidation. The 'resolution rate' metric alone could become the north-star KPI of the agent era.”
“For designer-developers who use Cursor or v0 to prototype quickly, this is a sanity check that doesn't require deep React expertise. A green health score before shipping is a meaningful confidence boost.”
“The self-service angle for non-technical teammates is underrated. Content and community teams using AI agents to handle engagement finally get visibility into whether those agents are actually helping users — without filing a Jira ticket to find out.”
