TL;DR

1.Cloudflare Web Analytics is free and privacy-friendly; Sleek is paid with significantly more features.
2.Cloudflare is fine for very basic needs — pageviews, top pages, top referrers, no UTMs, no events, no real-time, no AI, no revenue.
3.Sleek covers everything Cloudflare does plus custom events, UTM tracking, real-time, AI chat, Stripe revenue, and web vitals integrated with pages.
4.For under $9/mo difference, Sleek is the right pick for any team doing meaningful marketing or SaaS work.
5.Cloudflare is the right pick if you only want to know aggregate visitor counts and you're already on Cloudflare.

What Cloudflare Web Analytics is

Cloudflare Web Analytics is a free add-on for sites running on Cloudflare. It launched in 2020 as Cloudflare's answer to "what if Google Analytics, but free, privacy-friendly, and from a CDN we already trust."

It's genuinely privacy-friendly: cookieless, GDPR-compliant, no consent banner needed. And it's free, which is rare in this category.

The catch: feature-wise, it's very basic. Pageviews, top pages, top referrers, country breakdown, browser/OS — that's mostly it. No custom events, no UTM-based campaign reporting, no real-time, no funnel analysis, no revenue tracking, no AI.

At a glance

Pricing: Cloudflare free; Sleek $9/mo
Custom events: Cloudflare no; Sleek yes
UTM campaign tracking: Cloudflare basic; Sleek full reporting
Real-time: Cloudflare delayed (15-min lag); Sleek instant
Stripe revenue: Cloudflare no; Sleek native
AI chat: Cloudflare no; Sleek yes
Web vitals: Cloudflare yes (basic); Sleek per-page integrated
Bot filtering: both filter bots aggressively

Where Cloudflare wins

Free — no monthly cost at any traffic level
Already integrated if your site is behind Cloudflare
Privacy-friendly by default with no banner needed
Solid bot filtering using Cloudflare's edge network
No script needed if you use Cloudflare proxy (server-side metrics)

Where Sleek wins

Custom events for conversion and engagement tracking
Full UTM campaign reporting (Cloudflare's campaign reporting is minimal)
Real-time visitor view with live globe
AI chat for natural language queries
Native Stripe integration for revenue alongside traffic
Web vitals per page integrated with the page report
Funnel analysis and goal tracking
Public dashboards for sharing

When free is too expensive

Cloudflare's analytics is good enough for "I just want to know if anyone's visiting my site." For anyone running marketing, SaaS, or content with measurable goals, the missing features become real costs.

No UTM campaign reporting means you can't measure ROI per channel. No custom events means you can't track conversions. No real-time means you can't monitor launches. No revenue integration means you don't see what traffic is making money.

These aren't edge cases — they're table-stakes features for analytics that drives decisions. Cloudflare's "free" pays you back in missed insights.

tip:A useful litmus test: do you make any decisions based on your analytics? If yes, Cloudflare's feature set probably doesn't cover what you need to decide. The $9/mo for Sleek pays for itself in the first month of better decisions.

Cloudflare's real strength: as a complement, not replacement

Cloudflare Web Analytics is great as a "second opinion" alongside your primary analytics. It runs on the edge, sees server-side traffic data, and can catch traffic your client-side tool misses (rare with privacy-friendly tools, but possible with GA4).

Many teams run Sleek as their primary analytics + keep Cloudflare's analytics enabled for free as a sanity-check view. They show different things and the comparison can be useful.

Privacy and compliance

Both Sleek and Cloudflare are cookieless, GDPR-compliant, and CCPA-compliant. Neither requires a consent banner in the EU.

Cloudflare Web Analytics has the additional benefit of running on Cloudflare's edge network — no third-party JavaScript needed for some setups (server-side mode). This is particularly useful for sites with strict CSP requirements.

Who should pick Cloudflare

Personal blogs / hobby sites where the only goal is "did anyone visit?"
Sites already on Cloudflare with no marketing or conversion tracking needs
Privacy-extreme buyers who want zero third-party JavaScript on their site
Sites with extremely tight budgets where $9/mo is meaningful

Who should pick Sleek

Anyone running marketing campaigns who needs UTM tracking
SaaS founders who want Stripe revenue tracking
Content creators tracking subscribe button conversions
Ecommerce stores tracking purchases
Anyone who would benefit from an AI chat for analytics
Teams that need real-time visitor view during launches

How to migrate from Cloudflare to Sleek

Sign up for Sleek and add your domain.
Paste the Sleek snippet into your <head> (above or below the Cloudflare beacon — they don't conflict).
Run both tools in parallel for a week. Verify Sleek's numbers are similar to Cloudflare's (within 5%).
Once Sleek's numbers look right, you can either disable Cloudflare Web Analytics or keep it as a free secondary view.
Set up custom events, UTM campaigns, and Stripe integration in Sleek to capture the data Cloudflare didn't track.

The verdict

Cloudflare Web Analytics is fine for personal sites and very basic needs. It's not analytics for a business.

For anyone making decisions based on traffic data — marketers, SaaS founders, content creators, ecommerce operators — Sleek's $9/mo is a no-brainer upgrade. The features Cloudflare lacks (UTM tracking, custom events, real-time, AI, revenue) are exactly the features that make analytics useful for business decisions.

Use both: Cloudflare as a free secondary view, Sleek as your primary source of truth.

Frequently asked questions

Is Cloudflare Web Analytics really free?

Yes, completely. There's no event limit, no site limit, no premium tier. Cloudflare offers it as a value-add for sites already on Cloudflare's network. The catch is in features — basic-only.

Can I use Cloudflare Web Analytics without using Cloudflare DNS?

Yes. Cloudflare Web Analytics works as a JavaScript beacon installed on your <head>, similar to Plausible or Sleek. You don't need to route your DNS through Cloudflare to use it.

Is Cloudflare more privacy-friendly than Sleek?

They're equivalent on privacy properties. Both are cookieless, both don't collect personal data, both don't require consent banners. The difference is feature depth, not privacy.

Does Cloudflare track UTM parameters?

Cloudflare's campaign reporting is minimal — it shows traffic by source but doesn't fully decode UTM source/medium/campaign the way Sleek does. For marketing teams running campaigns, this is a significant limitation.

Can I run Sleek and Cloudflare Web Analytics together?

Yes. They don't conflict. Many teams run Sleek as primary + Cloudflare as a free sanity-check secondary. The numbers should match within 5%.

Does Cloudflare have AI chat or revenue tracking?

No, neither. These are Sleek-specific features. If you need AI chat for analytics or Stripe revenue alongside traffic, Sleek is the only privacy-friendly option that includes both natively.
