AutoCMP, OneTrust, and Cookiebot each target different segments. OneTrust is enterprise-grade but expensive and complex. Cookiebot is affordable but limited on customization and Google Consent Mode v2 support. AutoCMP sits in the middle: full Consent Mode v2, script blocking, and GTM integration starting at $49/mo with no per-pageview pricing.
Choosing a consent management platform shouldn't require a procurement team and a six-week evaluation. But with dozens of CMPs on the market, from enterprise behemoths to free-tier tools, it's hard to know which one actually fits your needs. This is an honest comparison of AutoCMP, OneTrust, and Cookiebot (now Usercentrics), the three names that come up most often.

OneTrust: the enterprise suite
What it does well
OneTrust isn't just a cookie banner. It's a full privacy management platform. Consent management is one module in a suite that includes data mapping, DSAR automation, vendor risk management, GRC, and AI governance. If you're a large enterprise that needs all of these capabilities under one roof, OneTrust is the market leader.
- Comprehensive privacy program management beyond just cookies
- Deep integrations with enterprise tools (Salesforce, SAP, ServiceNow)
- Dedicated customer success managers and implementation support
- Strong regulatory intelligence and compliance automation
- Trusted by thousands of Fortune 500 companies
Where it falls short
- Massive overkill for websites that just need cookie consent
- Pricing is opaque and expensive, typically $10K-$50K+/year for mid-size deployments
- Implementation takes days to weeks, often requiring professional services
- Banner performance can be sluggish. Script sizes often exceed 100KB
- UI feels dated compared to modern SaaS tools
- Annual contracts with no month-to-month option
OneTrust was also hit with significant layoffs in 2022 and has been restructuring, which has led to mixed reviews on support quality and product velocity. That said, if you're building a comprehensive privacy program at enterprise scale, it's still the most complete platform.
Cookiebot (Usercentrics): the incumbent
What it does well
Cookiebot has been in the cookie consent space since before GDPR enforcement began. It's well-known, widely deployed, and has a generous free tier for small sites. It was acquired by Usercentrics in 2021 and now operates as part of their product suite.
- Free tier for sites with up to 100 pages, genuinely useful for blogs and small sites
- Large cookie database for automatic classification
- WordPress plugin and various CMS integrations
- IAB TCF 2.2 certified
- Well-documented with a large community
Where it falls short
- Free tier forces Cookiebot branding on your consent banner
- Customization is limited compared to newer platforms
- Dashboard feels cluttered and hasn't been significantly modernized
- Pricing scales by page count and domain count, and can get expensive as you grow
- Geo-targeting and advanced features locked to higher tiers
- Script size is larger than necessary (~40-60KB)
Cookiebot is a solid choice if you're a small site that fits within the free tier, or if you're already using Usercentrics' broader product suite. For growing businesses, the page-count pricing model can become a pain point.
AutoCMP: built for the modern web
What it does well
Full disclosure: this is our product. But here's what we built and why:
- One script tag, 5-minute setup, no implementation project needed
- Lightweight SDK (<15KB gzipped), won't slow down your site
- Google Consent Mode v2 built in, works automatically, no configuration
- Automatic geo-targeting: GDPR banners for EU, CCPA opt-out for California, nothing where not needed
- Built-in cookie scanner: discover and categorize all cookies on your site
- Modern dashboard with real-time consent analytics
- Script blocking: non-essential scripts don't fire until consent is given
- Month-to-month billing, no annual contracts required (20% discount if you go annual)
- Custom branding on all plans, so your banner matches your site, not ours
Where we're still growing
We believe in being honest about where we are:
- We're newer. OneTrust and Cookiebot have years of market presence and larger cookie databases
- No IAB TCF certification yet (on the roadmap)
- No built-in DSAR management or full privacy program tools. We focus on consent
- Smaller integration ecosystem (we support GTM, GA4, and major ad platforms, but not every niche tool yet)
Pricing comparison
AutoCMP
| Plan | Monthly | Annual (20% off) | Includes |
|---|---|---|---|
| Standard | $49/mo | $39/mo | 1 domain, 50K consents/mo, 2 seats |
| Business | $149/mo | $119/mo | 5 domains, 500K consents/mo, 5 seats |
| Agency | $349/mo | $279/mo | Unlimited domains, unlimited consents, 10 seats |
OneTrust
OneTrust doesn't publish pricing. Based on market data, expect:
- Small business: $2,500-$5,000/year
- Mid-market: $10,000-$30,000/year
- Enterprise: $50,000-$200,000+/year
- Annual contracts only, typically 2-3 year terms
Cookiebot
| Plan | Price | Includes |
|---|---|---|
| Free | $0 | 1 domain, 100 pages, Cookiebot branding |
| Essential | ~$14/mo | 1 domain, 500 pages, limited customization |
| Premium | ~$40/mo | 1 domain, 5,000 pages, full customization |
| Enterprise | Custom | Multiple domains, unlimited pages |
Performance matters
Your consent banner loads on every single page view. If it's slow, your entire site feels slow. Here's how the scripts compare:
| CMP | Script Size (gzipped) | Impact |
|---|---|---|
| AutoCMP | <15KB | Minimal: loads in <100ms on most connections |
| Cookiebot | ~40-60KB | Moderate: noticeable on slower connections |
| OneTrust | ~80-200KB | Heavy: can add 200-500ms to page load |
For context, Google recommends keeping total JavaScript under 300KB for optimal Core Web Vitals. A consent banner that eats 200KB of that budget before your actual site loads is a real problem.

The CMP market has been dominated by overbuilt enterprise tools and legacy solutions for too long. We think there's room for something faster, simpler, and more developer-friendly. That's what we're building.
