Instrument on day one; opinions can wait. ## Combines with Dp, Bi - Guide: [Best analytics for solo founders (2026)](https://elems.ai/best/best-analytics-for-solo-founders.html) ## The top 5 — deep dossier (verified 2026-09-13) PostHog, unless something forces your hand — the free tier (1M events/mo plus replay, flags, and experiments) means a startup can instrument on day one for $0, 500k+ teams have, and the business behind it is real: $57.5M ARR growing 99% YoY into a $1.4B Series E. Amplitude is the pick when enterprise scale and governance decide — $410M ARR, 27% of the Fortune 100, and it now owns Statsig too. Mixpanel wins on analytics craft when you want depth without platform sprawl; Plausible when all you need is private, cookieless web stats for $9; Vercel Analytics when you're already deployed there and want numbers with zero setup. 1. **PostHog** (PostHog) — Free 1M events/mo · usage-based from $0.00005/event (volume discounts to $0.000009) · Boost $250/mo · Scale $750/mo · Enterprise custom. Best for: Startups that want analytics, session replay, feature flags, experiments, surveys, and error tracking as one instrumented stack from day one — free until real traction. Why: The builder default on the numbers: 500k+ teams, 19 bundled products, and the most generous free tier in the category (1M events + 5K replays + 1M flag requests monthly). Revenue validates the model — $57.5M ARR by Feb 2026, up 99% YoY, after a $75M Series E at $1.4B led by Peak XV (Sep 29, 2025). It is also the most AI-forward: MCP, AI observability, and a 'self-driving product' agenda that auto-diagnoses issues and opens PRs. Watch: Act 2 sprawl risk — 19 products and a stated pivot toward broader dev tooling stretch focus, and the UI shows it. ARR is still a seventh of Amplitude's, and usage-based bills surprise teams who never set billing limits. [https://posthog.com](https://posthog.com) 2. **Amplitude** (Amplitude (NASDAQ: AMPL)) — Free 2M events/mo · Plus usage-based from $0 (scales to 70M events) · Growth & Enterprise custom, event-based · unlimited seats all plans. Best for: Scale-ups and enterprises that need governed, deep behavioral analytics — cohorts, monitoring, RBAC — plus experimentation, on a vendor procurement already trusts. Why: The category's public-company anchor: $410M ARR (+22% YoY) and its first $100M+ quarter in Q2 2026, 5,200+ paying customers, 27% of the Fortune 100, and G2's #1 in Product Analytics for 24 straight quarters. It has consolidated the field around itself — acquiring June (Aug 2025) and then the Statsig platform from OpenAI's orbit (May 5, 2026) — and rebuilt the product line around AI agents (Feb 2026 launch). Watch: Free tier is generous but the cliff to custom-priced Growth/Enterprise is steep and opaque — small teams routinely bounce off sales-led pricing. Still GAAP-unprofitable, and the Statsig integration ('full interoperability' promised, data-layer only in phase 1) is unfinished. [https://amplitude.com](https://amplitude.com) 3. **Mixpanel** (Mixpanel) — Free 1M events/mo · Growth $0.28/1K events after free 1M (volume discounts) · Enterprise custom · first year free for startups (<5yrs, ≤$8M raised). Best for: Product teams that want the best pure analytics UX — fast ad-hoc exploration, boards, cohorts — without adopting a whole platform. Why: Still the craftsman's analytics tool: 29K customers, the most polished query/report experience in the category, and a credible 2026 AI reinvention — 'Product Intelligence Platform for the AI era' with MCP, a Slack/Claude/ChatGPT/Cursor agent, root-cause-analysis agents, and headless Python access. It added replay, flags, and experiments, closing the bundle gap with PostHog. Watch: Privately held with no disclosed ARR since its 2021 $1.05B round — the only top-5 pick whose business trajectory can't be verified. Squeezed from below by PostHog's free bundle and from above by Amplitude's enterprise machine; pricing has churned repeatedly (MTU → events). [https://mixpanel.com](https://mixpanel.com) 4. **Plausible** (Plausible Analytics (OÜ, bootstrapped)) — Starter $9/mo (10k pageviews, 1 site) · Growth $14 · Business $19 · Enterprise custom · 30-day trial · AGPL community edition self-hostable. Best for: Founders who want honest, cookieless website numbers — no consent banner, no Google — in a one-page dashboard they'll actually look at. Why: The proof that privacy-first analytics is a durable business, not a feature: 20k paying subscribers and 260B pageviews tracked by a profitable, investor-free team of 10 running on European-owned infrastructure since 2018. The 54x-smaller-than-GA script keeps sites fast, and open-source code keeps the trust auditable. Watch: Web analytics only — no user-level cohorts, funnels are basic, and there is deliberately no session replay or flags; you will still need a product analytics tool once you have a product. The $9 tier's 10k pageviews is tiny, and the self-hosted community edition trails cloud on features. [https://plausible.io](https://plausible.io) 5. **Vercel Web Analytics** (Vercel) — Hobby free 50k events/mo · Pro $0.03/1K events (usage, shared team credit) · Web Analytics Plus add-on $10/mo (24-mo window, UTM, 8 props) · Enterprise custom. Best for: Teams already deploying on Vercel who want pageviews and custom events with literally zero instrumentation decisions — enable and ship. Why: The lowest-friction analytics in existence for its audience: one toggle, cookieless and privacy-friendly by default, priced per event at rates ($0.03/1K) that undercut most dedicated tools at small scale. For a pre-PMF Next.js app it answers 'is anyone using this?' without adding a vendor. Watch: It is a traffic counter, not product analytics — no funnels, retention, cohorts, or user-level exploration, and custom events carry only 2–8 properties. Hobby data is trapped in a 1-month window, collection pauses at the cap, and the data lives inside Vercel's platform lock-in. [https://vercel.com/analytics](https://vercel.com/analytics) ### How to choose - If You're pre-PMF and instrumenting for the first time → PostHog on the free tier — 1M events, replay, and flags cost $0, and switching costs later are the reason to pick the bundle now. Set a billing limit the day you add a card. - If You're at scale with a data team, compliance review, and an experimentation program → Amplitude — the $410M-ARR public vendor procurement already knows, now with Statsig's experimentation engine attached; budget for sales-led pricing. - If You want the sharpest ad-hoc analysis UX and already have replay/flags elsewhere → Mixpanel Growth — $0.28/1K events after a free million, and the startup program makes year one free. - If You need marketing-site numbers without a cookie banner, or your users are consent-sensitive (EU, dev tools, health) → Plausible at $9–19/mo (or Fathom at $15) — and accept that you'll add a product analytics tool separately when you have a product. - If You deploy on Vercel and analytics is a checkbox, not a discipline yet → Vercel Web Analytics — free to 50k events, one toggle — but migrate to a real product analytics tool before you need funnels, because history won't come with you. - If Your data must not leave your warehouse → Warehouse-native analytics (Kubit, Amplitude's warehouse-native mode, Optimizely/NetSpring) — or run it yourself on the stack in element Wh. ### The field (20 more) Statsig (acquired), Heap (acquired), Google Analytics 4, Fathom Analytics, Matomo, Umami, Rybbit, Openpanel, Microsoft Clarity, Pendo, Fullstory, LogRocket, Countly, Kubit, NetSpring (acquired), Cloudflare Web Analytics, Aptabase, Hotjar (renamed), June (dead), Indicative (dead) Full dossier data: https://elems.ai/e/an.json --- Source: [elems.ai](https://elems.ai/e/an.html) — the periodic table of the AI-led startup.
