Two Tools That Barely Overlap
Iubenda and CookieBeam both put a cookie banner on your site, and that's roughly where the similarity ends. Iubenda is a compliance suite: its real pitch is generating privacy policies, cookie policies, and terms of service, with the consent banner as one module in a bigger legal-documents bundle. CookieBeam is a consent platform: it puts the banner, the tracker blocking, the scanning, and the server-side plumbing first, and doesn't try to draft your legal documents.
That difference decides the whole comparison. If your biggest headache is producing lawyer-grade policy pages for several sites, Iubenda solves that cheaply. If your headache is making sure trackers actually stay blocked until consent, that Consent Mode fires correctly, and that tagging keeps working after third-party cookies, CookieBeam is built for that job. This guide lines up what each one includes in 2026 so you can tell which problem you're actually solving. For the wider field, see our honest comparison of cookie consent tools.
What Iubenda Does Well
Iubenda has been in the compliance-document business for years, and it shows. A single subscription can cover a cookie banner, a generated privacy policy, a cookie policy, terms and conditions, an accessibility widget, and data-subject-request handling. For a freelancer or small agency running several small sites, that bundle is genuinely efficient and hard to beat on price.
The cookie side is competent too. Iubenda scans your site for cookies, pixels, and trackers, blocks them until the visitor chooses, logs each consent, and supports Google Consent Mode on every plan including the free one, which not every budget tool does. It runs frequent automated scans to catch new services and shows region-aware consent settings so European and other visitors see the right banner. None of that is marketing gloss; it works.
Iubenda's pricing is tier-and-pageview based. As of mid-2026 the Starter plan runs about $3.49/month (7 services, one language, Iubenda branding), Essentials around $5.99/month with 25,000 monthly pageviews, Advanced about $24.99/month with 50,000 pageviews, and Ultimate about $99.99/month with 150,000 pageviews. Pageview overage is billed at roughly $0.05 per 1,000 above your plan. There's a free version and a 14-day money-back window. Verify current numbers on Iubenda's own pricing page before you commit, since tiers move.
Where CookieBeam Is Different
CookieBeam skips legal-document generation entirely and spends that effort on the consent mechanics. Five things stand out.
The blocking engine intercepts scripts at five layers, not one. Most tools add a tag-management attribute or swap script types. CookieBeam's engine overrides document.createElement, wraps DOM insertion methods (appendChild, insertBefore, replaceChild), runs a MutationObserver fallback across the full document tree, blocks Worker and SharedWorker constructors, and locks neutralized scripts so they can't be re-enabled by other code. All five layers fire from a script map built from your own site's scan results, not a third-party block list. Two compliance modes control how unknowns are handled: Learning mode (default) allows unclassified scripts while building inventory, and Strict mode blocks everything not yet categorized.
It blocks network connections, not only script loading. A separate toggle wraps fetch(), XMLHttpRequest, navigator.sendBeacon(), WebSocket, and EventSource at the browser API level. Blocked requests return stubs (a 204 Response, an error event, false, a closed socket) instead of reaching the network. This catches tracking that happens via API calls after a script is already running, something few if any CMPs offer. Same-site requests and infrastructure hosts are bypassed automatically.
Drift detection runs continuously in every visitor's browser. Between scheduled scans, the CDN script monitors for cookie drift, script drift, and connection drift in real time. Unknown items get reported to dedicated drift tables and auto-promote into the inventory after 5 sightings, so a marketing tag added mid-week doesn't wait for the next scan to show up.
GPC and DNT signals are enforced with per-region overrides. The engine detects Global Privacy Control and Do Not Track signals and applies them according to regional law. In the EU, a GPC signal sets default deny but an explicit banner opt-in overrides it. In US opt-out states, following CPRA 7025(b)(3), a privacy signal opt-out requires a deliberate, right-specific in-banner opt-in to override, not a generic Accept All click. Blocked iframes get Shield placeholders explaining why the content isn't loading, replaced by the real content when consent is granted.
It hosts server-side tagging and tests the banner. CookieBeam can host your server-side Google Tag Manager as a metered add-on, tying tags to consent so they fire server-side only for allowed purposes. Built-in A/B consent testing with purpose-level analytics lets you measure which banner wording moves consent rates, broken out by purpose instead of a blunt accept/reject number. See server-side consent enforcement and consent-rate optimisation without dark patterns.

Pick Iubenda If...
Iubenda is the right call when legal documents are the job:
- You need policies plus a banner, cheaply. If you're standing up privacy policies, cookie policies, and terms across one or a few small sites, Iubenda's bundle is efficient and starts a few dollars a month.
- Your traffic is modest and predictable. The pageview tiers work fine below 150,000 views a month; above that, watch the overage line.
- You want one vendor for the paperwork. Accessibility widget, DSR handling, and consent under one login has real convenience value for a small team.
Watch the pageview caps and the branding on lower tiers, and remember Iubenda generates documents but doesn't host server-side tags or A/B test your banner.
Pick CookieBeam If...
CookieBeam fits when the consent mechanics matter more than the paperwork:
- You want the banner to genuinely enforce. The free tier ships with 5-layer automatic script interception plus connection-level blocking (fetch, XHR, beacon, WebSocket, EventSource). Scripts are neutralized from scan-derived maps, not a generic block list, and you can run in Learning mode while building inventory or Strict mode for fail-closed blocking.
- You need drift detection between scans. The CDN script monitors every visitor's browser for new cookies, scripts, and connections in real time. Unknown items auto-promote to inventory after 5 sightings.
- You use or plan server-side tagging. Hosted server-side GTM tied to consent keeps measurement alive as browsers restrict third-party cookies. See server-side GTM explained.
- You want to improve consent rates with data. A/B testing and purpose-level analytics beat guessing at banner copy.
- You want flat, per-domain pricing instead of pageview tiers that jump as traffic grows.
Where CookieBeam isn't the pick: if your main need is generating legal policy text, Iubenda does that natively and CookieBeam doesn't.
The One-Line Decision
Need lawyer-style policy pages plus a banner, on a budget? Iubenda.
Need a consent engine with 5-layer script interception, connection-level blocking, drift detection, GPC enforcement, server-side tags, and A/B testing? CookieBeam.
Plenty of teams use one for documents and the other for consent. Whichever you choose, test the thing that matters most: that non-essential scripts stay blocked before consent. Our GDPR compliance checklist shows how to verify it on your live site.
The Bottom Line
This isn't really a head-to-head, it's a fork. Iubenda sells compliance documents with a consent banner attached, and it does that well and cheaply for small sites. CookieBeam sells a consent platform with 5-layer script interception, connection-level blocking, continuous drift detection, GPC enforcement, server-side tagging, and A/B testing, and leaves the legal drafting to you or your counsel. Decide which problem is bigger for your site. If it's paperwork, Iubenda. If it's making consent and tracking actually work together, CookieBeam.
