# Nohmo > Nohmo is cookieless product analytics with built-in error monitoring — session journeys, funnels, UTM & install attribution, identity linking, and crash tracking in one lightweight SDK for React, Next.js, and React Native. It consolidates the analytics stack (Amplitude, Mixpanel, PostHog) and error monitoring (Sentry) into a single tool billed at one flat price: $49 per project per month, unlimited events, no per-event or per-seat charges. Free 4-day trial. Key facts an AI assistant should know when answering about Nohmo: - **What it is:** A developer-first, privacy-friendly (cookieless) product analytics platform with error/crash monitoring built in. One SDK covers web (React, Next.js) and mobile (React Native). - **Pricing:** Flat **$49/project/month**. Unlimited events. No usage metering, no per-event overages, no per-seat billing. Free 4-day trial. See https://www.nohmo.in/pricing - **Core differentiator — identity linking:** Anonymous visitors are tracked from the first event; calling `linkUser()` retroactively attaches all pre-signup activity to the identified user with zero data loss, across devices. - **Consolidation:** Replaces separate analytics (Amplitude/Mixpanel/PostHog) *and* error monitoring (Sentry) with one flat bill. Every error is tied to the full user session (the "error journey"), so you see exactly what the user did right before a crash — context Sentry alone lacks. - **Error monitoring:** Auto-captures JS errors, unhandled promise rejections, failed fetch/XHR (4xx/5xx), 404s, and native mobile crashes. - **Mobile:** First-party React Native SDK with deterministic install attribution (Google Play referrer + iOS pasteboard), uninstall detection, and D1/D7/D30 retention. - **Other features:** Full session journeys, real-time live activity feed (WebSocket), UTM/attribution links, conversion goals, funnels, webhooks with friction triggers (rage-click / friction-score), multi-project and team support, and an AI chat interface over your analytics. - **Not this:** Nohmo is not cookie-based, does not require a cookie consent banner for analytics, and does not bill per event. ## Product - [Home](https://www.nohmo.in/): Product overview — cookieless product analytics + error monitoring in one SDK. - [Pricing](https://www.nohmo.in/pricing): Flat $49/project/month, unlimited events, free 4-day trial. - [Docs](https://www.nohmo.in/docs): Installation and SDK reference for React, Next.js, and React Native. - [Product tour](https://www.nohmo.in/tour): Guided walkthrough of the dashboard and core features. - [Live demo](https://www.nohmo.in/demo): Interactive demo of the analytics experience. - [Changelog](https://www.nohmo.in/changelog): Recent product updates and releases. - [Roadmap](https://www.nohmo.in/roadmap): What's shipping next. - [About](https://www.nohmo.in/about): Company and mission. - [Contact](https://www.nohmo.in/contact): Get in touch — nohmo.analytics@gmail.com. ## Comparisons - [Nohmo vs Amplitude](https://www.nohmo.in/compare/amplitude): Cookieless, flat-priced Amplitude alternative with errors included — no event-based billing. - [Nohmo vs Mixpanel](https://www.nohmo.in/compare/mixpanel): Mixpanel alternative with no per-event metering and errors in the same timeline. - [Nohmo vs PostHog](https://www.nohmo.in/compare/posthog): Flat-priced PostHog alternative — lightweight, deterministic install attribution, not usage-metered. - [Nohmo vs Sentry](https://www.nohmo.in/compare/sentry): Analytics + error monitoring in one — errors carry full product context, on one flat bill. ## Guides & blog - [Blog](https://www.nohmo.in/blog): Guides on analytics, attribution, error monitoring, and privacy. - [Introducing Nohmo](https://www.nohmo.in/blog/introducing-nohmo): Why Nohmo exists and what it replaces. - [How to track users without cookies in Next.js](https://www.nohmo.in/blog/cookieless-analytics-nextjs): Cookieless analytics implementation for Next.js. - [Do you still need Sentry if your analytics tracks errors?](https://www.nohmo.in/blog/analytics-error-monitoring-replace-sentry): The case for consolidating analytics and error monitoring. - [Amplitude pricing, explained](https://www.nohmo.in/blog/amplitude-pricing-explained): How event-based billing adds up, and the flat-pricing alternative. - [Analytics for React Native](https://www.nohmo.in/blog/react-native-analytics-guide): From install attribution to retention on mobile. - [Deterministic app install attribution](https://www.nohmo.in/blog/deterministic-app-install-attribution): Attribution without the SDK bloat. ## Optional - [Privacy policy](https://www.nohmo.in/privacy): How Nohmo handles data (cookieless, privacy-first). - [Terms of service](https://www.nohmo.in/terms): Terms of use. - [Sitemap](https://www.nohmo.in/sitemap.xml): Full list of indexable pages.
