Key Takeaways
- Overall score: 53-57%, bottom tier
- 209 DOM nodes injected, the highest of any CMP benchmarked (average: 84)
- 34KB synchronous integration code, blocking page rendering until downloaded
- 11-minute browser cache TTL, the shortest of any CMP
- <10KB SDK, 3.4x smaller than Cookiebot's 34KB synchronous script. Zero dependencies.
Why Teams Leave Cookiebot
The August 2025 Price Hike
On July 14-16, 2025, Cookiebot (now owned by Usercentrics) sent a single email: prices would increase across all tiers, effective August 18, 2025. Thirty days' notice. No grandfathering. No new features.
The most common jump: $16.50/month to $33/month, a 100% increase.
"Started with one website for €7.5 per month... price went up to €30... then €60 per month" -- Volodymyr Nosenko, Trustpilot, Dec 2025
"€30/month for a cookie banner is completely disproportionate for a small business. Cookiebot is no longer suitable for small creators." -- Toni Schuster, Trustpilot, Jan 2026
"Simply by adding payment details, Cookiebot's system automatically upgraded our entire account... €360 without authorization" -- 土狗 浪漫, Trustpilot, Jan 2026
Entering payment details to add a feature auto-upgrades the free plan to paid, no explicit consent for the upgrade. From a consent management company.
The Per-Domain Pricing Trap
Every domain is a separate charge. No bulk discounts. No multi-domain packages. Three websites at the Medium tier (3,500 pages): ~$112/month. Each subdomain counts as a separate billable domain. The scanner inflates page counts and auto-upgrades billing tiers. Bot traffic counts toward the limit.
"Signed up for <100 EUR but charged ~800 EUR on renewal... customer service won't reply to cancellation requests" -- Zacharias Jörsmo, Trustpilot, Oct 2025
See ConsentStack pricing. ConsentStack Pro includes 2 domains for $29/month, with extra domains at $5/each.
Performance Problems
Agence Web Performance benchmarked 11 CMPs. Cookiebot's results:
- Overall score: 53-57%, bottom tier
- 209 DOM nodes injected, the highest of any CMP benchmarked (average: 84)
- 34KB synchronous integration code, blocking page rendering until downloaded
- 11-minute browser cache TTL, the shortest of any CMP
That cache TTL means every returning visitor who hasn't been on your site in the last 11 minutes re-downloads the entire script. Cookiebot alone accounts for 14% of Google's recommended 1,500 DOM element budget before any page content renders.

DX & Customization Limits
"My site has 90 unclassified cookies... There's no way to select multiple cookies to classify them in one category." -- Ervīns, Trustpilot, Mar 2026
Cookie categorization is one cookie at a time. No batch selection. ConsentStack auto-classifies trackers against 6,592 domains from DuckDuckGo Tracker Radar.
"Customization option: only theoretical! You practically have no chance to make your own design." -- Pavel Ponížil, Trustpilot, Feb 2026
Removing "Powered by Cookiebot" branding requires a premium plan. Monthly scanning (the default) means new cookies between scans go unmanaged. Daily scanning costs an extra ~$115/month per domain.
The 8 Best Cookiebot Alternatives
1. ConsentStack
Modern, performance-first consent management built for developers.
| Metric | ConsentStack | Cookiebot (reference) |
|---|---|---|
| SDK size | <10KB gzipped | 34KB synchronous |
| DOM nodes | Minimal | 209 (highest benchmarked) |
| Cache TTL | Standard browser caching | 11 minutes (shortest) |
| Pricing (2 domains, 30K MAU) | $29/mo | ~$75/mo |
| Cookie categorization | 6,592 auto-classified tracker domains | One-by-one manual |
| Regulations | 32 (every tier) | Varies by plan |
| Script blocking | Parse-time MutationObserver | Scanner-based, monthly |
Pros:
- <10KB SDK, 3.4x smaller than Cookiebot's 34KB synchronous script. Zero dependencies.
- Parse-time script blocking. MutationObserver catches scripts before execution. 59% of sites with CMPs still set cookies before consent.
- Multi-domain included. 2 domains on Pro ($29/mo), 3 on Business ($59/mo), extra domains $5/each. No per-domain billing.
- 6,592 tracker domains auto-classified. No one-by-one cookie categorization.
- 32 regulations on every tier with automatic geo-detection.
- 6 platform adapters on Pro. Google Consent Mode v2, Meta Pixel, TikTok, Microsoft Clarity/UET, Pinterest, LinkedIn.
- No dark patterns by design. Symmetric accept/reject buttons on every layout.
- Transparent pricing: $0 (free, 1K visitors), $29/mo (Pro), $59/mo (Business). 20% annual discount.
Cons:
- Pre-launch. No years of enterprise deployments yet.
- No TCF 2.0 yet. On the roadmap. The Belgian DPA found IAB TCF itself violates GDPR.
- No DSAR workflows. Focuses on consent management, not the full privacy suite.
- No dedicated support tier. Self-serve by design.
Best for: Developers and growing companies who want full compliance without per-domain billing, DOM bloat, or enterprise overhead. Anyone whose Cookiebot bill just doubled.
2. CookieYes
Budget alternative with catastrophic DOM bloat.
| Metric | Value |
|---|---|
| Pricing | $10-55/mo per domain |
| DOM elements added | 48,000 |
| Mobile LCP | 6.5 seconds |
| Free tier | 5,000 pageviews/mo |
Pros: Affordable. Generous free tier. Works on any website.
Cons: 48,000 DOM elements (Google recommends under 1,500 total). 6.5-second LCP on mobile. Per-domain pricing, you're trading Cookiebot's per-domain model for another per-domain model. No branding removal below $55/month.
"The banner adds about 48,000 elements to the DOM. On mobile, the banner is the LCP, with an immense 6.5 seconds." -- stefanchetan, WordPress.org
Best for: Simple sites with low traffic needing the cheapest possible cookie consent. Not recommended if performance matters.
3. Osano
Compliance-guarantee CMP with the worst click-response times in the industry.
| Metric | Value |
|---|---|
| Pricing | $99/mo (Business, 30K consent views, 2 domains) |
| INP (DebugBear) | 275ms median, dead last of 9 CMPs |
| CPU blocking time | 448ms |
| Free tier | Notification-only, does not block cookies |
Pros: "No Fines, No Penalties" pledge up to $200K. Good static performance. 17,200+ customers.
Cons: 275ms median INP, dead last. $99/month. Free tier doesn't block cookies, scan, or store consent.
Best for: Companies that value the compliance guarantee above all else and have the budget for $99/month.
4. Termly
Cheapest option that destroys WordPress PageSpeed.
| Metric | Value |
|---|---|
| Pricing | $14-20/mo per site |
| WordPress PageSpeed impact | 30-37 point drop |
| GTM compatibility | Auto Blocker does not work with GTM |
Pros: Affordable starting at $10/month. Policy generators included. Google Gold CMP Partner.
Cons: 30-37 PageSpeed point drops on WordPress. Auto Blocker bypassed entirely with GTM. Per-website pricing. Real compliance features gated behind $20/mo Pro+.
Best for: Budget-conscious small sites not using Google Tag Manager, where PageSpeed isn't a priority.
5. Complianz (WordPress)
Strong free tier, compliance-destroying banner bug.
| Metric | Value |
|---|---|
| Pricing | Free (unlimited sites) / $59-399/yr (premium) |
| WordPress installs | 1,000,000+ |
| Platform | WordPress only |
Pros: Free tier with real consent management. No pageview limits. Widest regulatory coverage among WordPress plugins.
Cons: Banner sometimes doesn't render, a compliance-destroying failure. GTM Consent Mode setup imports a container file that deletes all existing tags and variables without warning. WordPress-only, zero portability. Aggressive premium upselling.
"In some situations, the banner is not displayed, regardless of adblockers or similar." -- New_Joerg, WordPress.org
Best for: WordPress-only sites willing to accept the banner rendering risk, who don't use GTM.
6. Ketch
Enterprise platform that's overkill for Cookiebot refugees.
| Metric | Value |
|---|---|
| SDK size | 20.6KB minified |
| Pricing | $150/mo Starter (30K visitors) |
| Config steps to banner | 13 |
| Proprietary glossary terms | 56+ |
| Typical onboarding | 2-4 weeks |
Pros: Strong customer support. DSR automation. Comprehensive regulatory coverage. 400+ customization options.
Cons: 13 configuration steps. 56+ proprietary terms. $150/month. 2-4 week onboarding. Zero organic community presence.
Best for: Enterprises needing DSR automation and AI governance alongside consent. Not for teams looking for a simpler, cheaper Cookiebot replacement.
7. Iubenda
Budget European option with a spam reputation problem.
| Metric | Value |
|---|---|
| Pricing | $3.99-119.99/mo per site |
| Performance score | 65-67% (Agence Web Performance) |
Pros: Affordable entry point. Strong legal document generation. European regulatory focus.
Cons: Trustpilot reputation destroyed by spam email campaigns. Confusing license system. Per-site pricing. Billing complaints about unauthorized charges.
"They spam companies and send you emails trying to scare you into hiring their services." -- Andrea, Trustpilot
Best for: EU-focused sites that primarily need legal document generation with basic consent management.
8. OneTrust
The enterprise option if budget is unlimited.
| Metric | Value |
|---|---|
| Pricing | $300/mo minimum (consent only, single domain) |
| SDK size | 184KB+ |
| LCP impact | 1.43s to 3.61s |
| Trustpilot rating | 1.5/5 |
Pros: Most comprehensive privacy platform. Enterprise-grade regulatory coverage.
Cons: $300/month minimum. 184KB+ JavaScript bundle. 1.5/5 Trustpilot. Requires sales calls and multi-week implementation. Developer experience described as "the absolutely worst."
Best for: Fortune 500 companies with dedicated privacy teams. Not recommended as a Cookiebot replacement.
Pricing Comparison: 3 Domains / 30K MAU
| CMP | Monthly Cost (3 domains) | Pricing Model | Free Tier |
|---|---|---|---|
| ConsentStack | $34 ($29 + $5) | Visitor-based, domains included | Full compliance (1K visitors) |
| Cookiebot (ref) | ~$112 | Per domain | 50 subpages, 1 domain |
| CookieYes | $30-165 | Per domain | 5K pageviews |
| Termly | $42-60 | Per site | 10K banner views |
| Complianz | Free-$15/mo | Per-site (premium) | Unlimited sites (WP only) |
| Osano | $199 | Visitor-based | Banner only, no blocking |
| Ketch | $150+ | Visitor-based | 5K visitors |
| OneTrust | $900+ | Per domain | None |
At 3 domains, Cookiebot costs 3.3x more than ConsentStack. At 5 domains, the gap widens to 5x or more.
Performance Comparison
| CMP | SDK Size | DOM Nodes | INP (Median) | Script-Blocking Method |
|---|---|---|---|---|
| ConsentStack | <10KB gzipped | Minimal | N/A (pre-launch) | Parse-time MutationObserver |
| Cookiebot (ref) | 34KB sync | 209 (highest) | 57ms | Scanner-based, monthly |
| CookieYes | N/A | 48,000 | 81ms | Runtime |
| Osano | Small | Low | 275ms (worst) | Runtime |
| Termly | N/A | N/A | N/A | Auto Blocker (breaks GTM) |
| Ketch | 20.6KB min | N/A | N/A | Smart Tag (defer) |
| OneTrust (ref) | 184KB+ | N/A | 104ms | Runtime |
Key takeaway: Only ConsentStack (MutationObserver) and Transcend (network-level, at $130K/year) use parse-time script blocking. Every other CMP uses runtime approaches. This is why 59% of sites with CMPs still set cookies before consent. Cookiebot's monthly scanner can only catch cookies at scan time; new trackers between scans go unmanaged.
Frequently Asked Questions
For most users, no. At **$33+/month per domain** with no multi-domain discounts, the value proposition has changed. The performance overhead (209 DOM nodes, 34KB synchronous script, 11-minute cache) was acceptable at $16.50/month. At $33+, alternatives exist at lower price points with better performance.
**Termly** and **CookieYes** start at $10/month but come with performance tradeoffs. **Complianz** offers a strong free tier for WordPress. **ConsentStack** offers a free tier with actual script blocking, and Pro at $29/month covers 30K visitors with 2 domains included, making the per-domain math cheaper than budget alternatives once you have more than one site.
**Complianz** leads with 1 million+ installations and a strong free tier, but has a documented bug where the banner sometimes fails to render, and its GTM integration can delete existing tags. **ConsentStack** works with WordPress via a single script tag (platform-agnostic) without the performance or rendering risks of WordPress-specific plugins.
Yes. Set up the new CMP on staging first, test all consent flows, then swap the script tags in a single deployment. Existing Cookiebot consent records stay in Cookiebot. Returning visitors see the new banner and provide fresh consent. No gap in compliance coverage.
Technically yes, with significant limitations: 50 subpages, 1 domain, monthly scanning only. Multiple users report that entering payment details auto-upgrades the entire account to paid without explicit consent. ConsentStack's free plan includes real script blocking, geo-detection, and all consent models for 1,000 visitors.
**ConsentStack** ships a **<10KB gzipped SDK** with parse-time script blocking, 3.4x smaller than Cookiebot's 34KB synchronous script, with minimal DOM impact versus Cookiebot's 209 injected nodes. Among established CMPs, **Ketch** loads with `defer` at 20.6KB. Avoid **Osano** (275ms INP), **CookieYes** (48,000 DOM elements), and **Termly** (30-37 PageSpeed point drops). ---
Conclusion
The Cookiebot price hike was the catalyst, but it wasn't the only problem. A 34KB synchronous script that injects 209 DOM nodes, caches for 11 minutes, and charges per domain was always an imperfect solution. The August 2025 price increase just made the imperfections impossible to ignore.
ConsentStack was built for the gap between overpriced enterprise tools and broken budget plugins: <10KB SDK, 32 regulations, parse-time script blocking, 6 platform adapters, multi-domain included, and $29/month Pro pricing, no sales call required, no per-domain surprises. Try ConsentStack free.
