Amplitude
Amplitude is a digital analytics platform from San Francisco, founded in 2012 by Spenser Skates, Curtis Liu and Jeffrey Wang and listed on Nasdaq (AMPL) since its 2021 direct listing. It started as event-based product analytics for mobile apps and now helps product, growth and marketing teams see how people use their apps and websites and what drives conversion and retention.
The platform combines product and web analytics (funnels, retention, cohorts, journeys), session replay and heatmaps, feature flags and A/B testing, in-app guides and surveys (from the 2024 Command AI acquisition) and audience syncing to ad and messaging tools. AI agents can monitor dashboards, explain metric changes and answer questions, and an MCP server exposes Amplitude data to AI tools. Free covers 2 million events a month; Plus is usage-based; Growth and Enterprise are custom-priced through sales.
It fits product-led companies that need self-serve analysis for non-technical teams. Mixpanel is the closest rival with simpler pricing; PostHog is cheaper and open source with an engineering focus; Pendo is stronger on in-app guidance for B2B software; Google Analytics is free but built for marketing attribution.
In July 2026 Amplitude dropped the fixed 49 dollar Plus tier based on monthly tracked users for event-based pricing from 0 dollars, and the Free plan now includes session replay, guides and AI agents. Startups with under 20 employees and under 10 million dollars raised can apply for a free year of Growth.
Similarweb
Similarweb is a digital market intelligence platform founded in Tel Aviv in 2007 by Or Offer and listed on the New York Stock Exchange since 2021. It estimates traffic, engagement, audience and marketing channels for almost any website or app by combining panel data, public data and direct measurement from connected sites. The core job: see how competitors and markets perform online without their analytics.
The platform is sold in suites. Competitive Intelligence covers website traffic, engagement, demographics, traffic sources and benchmarking. The SEO suite adds keyword research, keyword gaps, rank tracking, backlinks and site audits, while AEO tools track brand visibility and citations in AI assistants. Ads intelligence covers paid search, display and social creatives. Self-serve plans are for one user and start at $129 a month for AEO alone or $199 for Competitive Intelligence; Business packages add longer history, country filters, API access and AI Studio.
Similarweb fits marketers, analysts, investors and agencies who need market share and competitor traffic numbers, not just SEO rankings. Its estimates are modelled, so small sites can be inaccurate, and the full value sits in expensive custom contracts. Semrush and Ahrefs are stronger and cheaper for day-to-day SEO, while SE Ranking suits agencies on a budget.
In September 2025 Similarweb launched an MCP server that lets AI tools such as Claude, Cursor and n8n query its traffic, keyword and app data directly. Before buying, use the 7-day free trial to check estimates against a site whose real analytics you know.
