Pick by the kind of growth you need. To measure and test what users do inside your product, PostHog's Claude Code plugin gives your agent its analytics, feature flags and A/B tests. To get new people to find you in Google and AI answers, Shipfound runs from Claude Code or Codex and ships the work as pull requests.
Why the tool should run inside your agent
Most developers already work in one. In May to July 2026, 90% of professional developers used AI coding agents at work at least weekly and 68% used them daily. About 39% used Claude Code at work, up from 18% in January 2026, and Codex grew from 3% to 16%. A growth tool your agent can call works where you already spend the day.
Two jobs, two kinds of tool
Measuring what users do
PostHog's plugin gives Claude Code 27+ PostHog tools for querying insights, managing feature flags, running A/B experiments, tracking errors and analyzing LLM costs, with 12 slash commands. Pick it when you have users and want to know what they do.
Getting found by new users
Shipfound audits what you have access to (your repo, Search Console, Bing, Gmail, Reddit and X), then ships site fixes, content and indexing as pull requests. It fills in directory listings and drafts replies for you to post. It also checks whether GPTBot, PerplexityBot and ClaudeBot crawl your pages, and whether ChatGPT, Perplexity, Google AI and Claude name you, asking each question 4 times. Pick it when few people know your product exists yet. It never posts or merges without you.
