Cookiebot vs CookieGuard: an honest 2026 comparison
Side-by-side: script weight, time-to-paint, customization, pricing, developer experience, and the one feature each tool does better.
We built CookieGuard because we were paying Cookiebot $99/month for a CMP that added 38 KB of JavaScript and shifted layout on every page load. So this comparison is biased — but the numbers below are objective and reproducible. Run the same Lighthouse audit yourself.
The TL;DR
Cookiebot is a mature, trustworthy product with a deep cookie database and decades of compliance experience baked in. If you have a 50-person legal team and you want bullet-proof regulatory cover, Cookiebot is the safer pick. CookieGuard is faster, prettier, cheaper, and has a real developer API — but we're a 2026 product, not a 2014 one.
1. Script weight and performance
| Metric | Cookiebot | CookieGuard |
|---|---|---|
| Gzipped script size | ~38 KB | 5.9 KB |
| First banner paint (P95) | ~200 ms | < 60 ms |
| Cumulative Layout Shift | 0.02–0.05 | 0 (Shadow DOM, position: fixed) |
| Number of network requests | 3–4 | 1 |
Cookiebot loads several feature modules on demand — language packs, the “cookie declaration”, etc. CookieGuard ships everything in one async file under 6 KB gzipped and lazy-loads only the locale chunk. On a Moto G mobile emulating 4G, the difference is the gap between a clean LCP and a yellow Lighthouse score.
2. Customization
Cookiebot has a wider library of pre-built layouts (banner, dialog, popup, slide-in, page consent, etc.) and per-region variations. CookieGuard ships fewer layouts but lets you change every visual property from a single config object — including animation, radius, shadow, position, button order, and CSS overrides via the Shadow DOM. We found that 99% of customers picked one of three layouts anyway.
3. Cookie scanner & taxonomy
Cookiebot wins here. Their database has been curated for over a decade and covers ~30,000 cookies. CookieGuard ships ~150 hand-curated entries plus pattern matching, and falls back to an LLM classifier for unknowns. We're catching up; if your site loads obscure third-party widgets, Cookiebot will get more of them right out of the box.
4. Google Consent Mode v2
Both tools fully support GCM v2. CookieGuard pushes denied defaults inside the loader (3 KB) before the rest of the script even arrives — meaning even tags that race the CMP get a denied state. Cookiebot does the same since their April 2024 update; before that they didn't. If you're still on an older Cookiebot install, double-check.
5. Pricing
| Site size | Cookiebot | CookieGuard |
|---|---|---|
| Up to 100k page-views | $15/mo | $9/mo |
| Up to 500k page-views | $48/mo | $9/mo (no PV cap) |
| Multi-domain (5 sites) | ~$240/mo | ~$45/mo |
| White-label | Enterprise | Agency tier |
CookieGuard is flat per site, no page-view tiers. Cookiebot scales with traffic. For a Shopify store doing 200k PV/month, the difference is roughly $40/month, every month, forever.
6. Developer experience
Cookiebot's API is functional but feels like 2015 — global variables, callbacks, no TypeScript types out of the box, sparse docs. CookieGuard ships:
- A typed
window.cookieguardnamespace onConsentChangeevent subscriptions returning unsubscribersready()as a Promise, not a global flag- OpenAPI 3.1 spec for the management API
- First-class Webhook firehose for consent events
7. The one thing Cookiebot does better
Cookie declaration page. Cookiebot's auto-generated cookie list is more polished and easier to embed on a custom domain. We're shipping equivalent in v1, but as of mid-2026 Cookiebot wins on this specific page.
8. The one thing CookieGuard does better
A/B testing. CookieGuard has split-testing of banner variants built in with sticky assignment, Bayesian significance, and one-click winner promotion. Cookiebot offers nothing comparable as of 2026 — you'd wire it up via GTM yourself.
Should you switch?
If you're paying Cookiebot > $40/month and not using their cookie declaration page on a custom domain, you're probably overpaying. Try CookieGuard free for 30 days, run both side by side on a staging environment, and compare the Lighthouse delta.
