Autocapture starts tracking immediately. Add custom events as you go — no data team required. npx @amplitude/wizard ### Understand immediately Funnels, retention, paths, cohorts. Session replay shows where users get stuck. Ask questions in natural language through AI or MCP. 10K MTUs free ### Experiment constantly Feature flags ship with your analytics. Run experiments, target cohorts, roll back — all connected to the same behavioral data. Unlimited feature flags Works where you work ## Access your data from wherever you build Query your product data in plain English from your terminal, IDE, or any MCP-compatible AI tool. No context-switching. ### Terminal or IDE Use the Amplitude MCP server to ask questions about your data in plain English from Claude, Cursor, or any MCP-compatible AI tool. Agents can run the CLI using `--agent` or `--ci` mode. ### Slack or Teams app Connect Amplitude to your team's messaging tool to get insights, create charts, and more where you work. ### Claude Code plugin Install the Amplitude plugin for Claude Code, which provides the same MCP tools along with built-in slash commands for quick access. Inside a Claude Code session: /plugin install amplitude Or from your terminal: claude plugin install amplitude Run `/mcp` in Claude Code and follow the browser prompts to log in to Amplitude. /amplitude:create-chart/amplitude:create-dashboard/amplitude:instrument-events/amplitude:replay-ux-audit/amplitude:weekly-brief Things to try once your data is flowing #### Watch your first session replay Review exactly what users experience in your app — every click, scroll, and hesitation. #### Launch a web experiment A/B test features with no extra code using the Visual Editor.

The Starter plan includes 10K MTUs per month, unlimited feature flags, session replay, web experiments, and full analytics — no credit card required. You can instrument your first event and see data in minutes without ever talking to sales. Amplitude is built for startups, full stop. A single developer can run npx @amplitude/wizard, get instrumented in one terminal session, and ship the first dashboard the same afternoon. No tracking plan exercise. No data team handoff. No engineering ramp-up. And because the same SDK, the same event schema, and the same dashboards scale from your first 100 users to your first 100 million, you never have to rip out your analytics and start over when you grow. Startups under 20 employees and under $10M raised can apply for the Amplitude Scholarship for a full year of the Growth plan free. The Startups plan gives early-stage startups one full year of our Growth plan at no cost. Eligibility: fewer than 20 employees and less than $10M raised. You get 200K MTUs, advanced experimentation, cohort analysis, and priority support — the full platform you'll need to scale. Amplitude has a CLI built specifically for developers: @amplitude/wizard. Run npx @amplitude/wizard from your project root and the CLI signs you into Amplitude, detects your framework, proposes events to track, installs the right SDK, sets up MCP for your editor, and builds your first dashboard. No separate install required, no global package to manage. The CLI is the fastest path to a working Amplitude setup, and it's the same tool whether you're instrumenting a brand new app or adding analytics to an existing codebase. Amplitude's wizard never writes code without your approval. It reads your codebase, proposes events, and shows you exactly what it wants to write before touching anything. You approve every change. The agent doesn't commit code, doesn't push to your repo, and doesn't make changes outside the events and SDK setup. You're always the last gate. Amplitude's wizard requires Node.js 20 or higher and a terminal with internet access. You don't need an existing Amplitude account, an API key in hand, or a tracking plan written up first. The wizard signs you in (or picks up an existing session) and lets you choose your org, project, and data region during setup. Full requirements and supported environments are in the Setup Wizard CLI docs. For most web or mobile apps, you can send your first event in minutes using npx @amplitude/wizard or a single SDK install. Autocapture starts tracking page views and clicks immediately. You add custom events incrementally as you build — no big upfront schema required. No. Amplitude uses the same SDK, the same event schema, and the same data pipeline across Starter, Growth, and Enterprise. Upgrading unlocks more capabilities — it never changes how your data is collected. Your instrumentation investment is permanent. The Amplitude MCP (Model Context Protocol) server lets you query your product analytics directly from Cursor, Claude Code, or any MCP-compatible AI tool. Ask questions like "What's my 7-day retention for users who completed onboarding?" in plain English, get answers in your IDE, and take action without leaving your editor. Amplitude maintains an open-source MCP marketplace with prebuilt plugins and skills for AI coding assistants. The current amplitude-analysis plugin includes seven reusable skills: create-chart, create-dashboard, analyze-chart, analyze-dashboard, analyze-experiment, analyze-feedback, and analyze-account-health. Install the marketplace once with /plugin marketplace add amplitude/mcp-marketplace, then add the plugin with /plugin install amplitude-analysis@amplitude. The marketplace works with Claude Code, Cursor, and Claude, and it's open for contributions. Amplitude is purpose-built for product analytics — not marketing attribution or A/B testing bolted onto an ad platform. The same SDK that powers your analytics also powers your feature flags, experiments, and session replay. Everything shares the same behavioral data model, so you never stitch together results from disconnected tools. ## Start building in 5 minutes Free plan. No credit card. No sales call.
