Best web analytics for vibe-coded apps (2026)

Once your app is live you need to know who visits, where they come from and whether they sign up. These web and product analytics tools are compared on what the free plan really includes, whether you need a cookie banner, and how fast a coding agent can add the script. Privacy-first picks (Umami, Plausible, Rybbit, Fathom, Simple Analytics) skip cookies; PostHog adds product analytics, replay and feature flags, and OpenPanel is an open-source product-analytics option priced only by events. Cloudflare Web Analytics is the free, cookieless pick for basic traffic stats and Core Web Vitals.

Traffic stats or product analytics?

Traffic stats tell you how many people visit, where they come from and which pages they read: Umami, Plausible, Rybbit, Fathom, Simple Analytics, Vercel Web Analytics and Google Analytics 4. Product analytics follows what users do inside your app (funnels, retention, user profiles): PostHog and OpenPanel. A new SaaS often starts with one of each kind, or just PostHog.

Free plans compared

PostHog is free every month for 1M events, 5K session recordings, 1M feature-flag requests and 100K error exceptions, with no card. Umami Cloud Hobby is free for 100K events on 1 website. Vercel Web Analytics includes 50,000 events a month on Vercel’s Hobby plan. Simple Analytics is free for hobby sites with a badge, and Google Analytics 4 is free. Plausible (30 days), OpenPanel (30 days), Rybbit (7 days) and Fathom (7 days, card required) offer cloud trials only.

What about 100K a month?

On list prices: PostHog and Umami Hobby $0; Rybbit Standard from $13/mo billed annually (100K pageviews); Fathom $15/mo (100K pageviews); Plausible Starter $19/mo (100K pageviews); OpenPanel $20/mo (100K events); Simple Analytics from $20/mo (100K pageviews). Pageviews and events are counted differently, so compare on your own traffic.

Open source you can self-host

Umami (MIT), Plausible, OpenPanel and Rybbit (all AGPL-3.0) are free to self-host, and PostHog has an MIT-licensed open-source edition. You pay only for the server and take on updates and backups.

Replays and errors without PostHog

Rybbit includes web vitals and error tracking on Standard and session replays on Pro (from $26/mo billed annually). OpenPanel includes session replay in its event-priced cloud. Umami adds 5,000 session replays and heatmaps on Business ($200/mo).

Let your coding agent read the numbers

PostHog, OpenPanel (38 tools) and Rybbit publish MCP servers, and Umami includes API and MCP access on Pro. With one connected, Claude Code, Cursor or Codex can answer “where did sign-ups drop this week?” from real data.
