How Much Does Optimizely Cost in 2026?
Last updated: August 16, 2026 · Originally published: April 29, 2025
Optimizely does not publish public list pricing. Based on Optimizely's plans page and multiple 2026 buyer reports, expect annual, sales-led contracts starting around $36,000–$40,000 per year for standalone Web Experimentation and scaling to $150,000–$500,000+ for enterprise multi-product deployments. Pricing is metered primarily on monthly tracked users (MTUs). These are estimates, not official price sheets. Vendr's marketplace median as of August 2026 is ~$81,447/year across 126 purchases — useful as a mid-point sanity check, not a quote.
Pricing at a glance (2026)
Contracts scale with MTUs — unique visitors who hit a page running an active experiment in a calendar month. Not sitewide traffic, and not pageviews.
| Deployment size | Reported annual contract | Contract terms | What drives the number |
|---|---|---|---|
| Small — under 250K MTUs | ~$36,000–$80,000 | Annual (sometimes multi-year) | Standalone Web Experimentation, lowest MTU tier (ConversionWax, Spike) |
| Mid-market — 250K–1M MTUs | ~$80,000–$150,000 | Annual; auto-renewal commonly reported | Higher MTU tier, added modules, support SLA |
| Enterprise — 1M+ MTUs or multi-SKU | ~$150,000–$500,000+ | Annual or 2–3 year deals | CMS + experimentation + commerce; implementation services |
| Median across Vendr marketplace deals | ~$81,447 | Annual | Low–high roughly $26K–$261K across 126 purchases (Vendr, retrieved Aug 2026); ConversionWax previously cited $78K / 109 buyers |
Buyer reports also describe internal tier names, useful for sanity-checking a quote (Kirro):
| Tier | Reported annual cost | Roughly what it covers |
|---|---|---|
| Essentials | $25,000–$40,000 | Basic web testing, limited traffic |
| Business | $65,000–$95,000 | Web testing plus more features, higher traffic limits |
| Accelerate | $120,000–$180,000 | Full platform access, priority support |

Estimate your Optimizely cost in four steps
There is no official Optimizely pricing calculator, so this is the arithmetic buyers end up doing by hand:
- Count testable traffic, not total traffic. Monthly unique visitors to the specific pages you plan to test. A 2M-visitor site testing only its pricing page may consume far fewer MTUs than its traffic suggests.
- Map to an MTU band. Under 250K → $36K–$80K. 250K–1M → $80K–$150K. Over 1M → $150K+.
- Multiply per additional module. Adding Personalization, Feature Experimentation, CMS, or Commerce roughly doubles contract value or more.
- Add 35–50% for year one. Implementation, training, and the internal headcount to run the program. The license is typically only 50–65% of first-year total cost of ownership.
Worked example from Spike's 2026 analysis: a B2B SaaS company with 400,000 monthly visitors signs Web Experimentation at $55,000/year, then adds a $40,000 systems-integrator engagement, $15,000 of training, and a half-time analyst at $45,000 loaded cost. Real year-one outlay: $155,000 — nearly triple the license.
What you can negotiate
Because there is no list price, nearly everything is negotiable. Reported buyer leverage points:
- Multi-year terms — 20–30% off for a 2–3 year commitment
- Bundling — 25–35% when licensing multiple products together
- Quarter-end timing — more flexibility as Optimizely's fiscal quarter closes
- Renewal escalation cap — negotiate the cap upfront; uncapped renewal increases are a recurring complaint
- MTU overage rate — agree the per-unit rate before you need it, not after you breach the cap
How Optimizely pricing works
Optimizely uses custom, quote-based pricing tailored per account. Their plans page routes every product to "Talk to Sales" — there is no self-serve checkout or published tier matrix.
That means your final number depends on a bundle of factors (traffic, modules, support, security) rather than a single list price. The DXP Scorecard rates Optimizely among the least transparent vendors in the CMS/experimentation market, with third-party 2026 estimates spanning roughly $40K–$300K+ depending on deployment size.
Common contract patterns reported by buyers:
- Annual or multi-year commitments (monthly plans not offered)
- MTU-based metering for experimentation products, with older contracts and some SKUs still on impressions
- Multi-product bundling (Web Experimentation, Feature Experimentation, CMS, Personalization, Commerce sold separately)
- Auto-renewal clauses — confirm cancellation notice windows before signing
- Implementation and training often add 35–50% on top of the license in year one (Kirro)
What impacts Optimizely pricing?
| Factor | What changes price | How to estimate your tier |
|---|---|---|
| MTUs / traffic | Higher monthly tracked users raise platform fees; overages can apply | Share peak monthly traffic, pages under test, and seasonal spikes |
| Products / modules | Each SKU (Web, Feature, CMS, Personalization) is priced separately; bundles cost more | List only modules you will use in year one |
| Experimentation type | Web A/B tests vs server-side feature flags vs full-stack experimentation | Clarify client-side vs server-side needs upfront |
| Support & SLA | Premium support, dedicated CSM, uptime SLAs | Ask what is included in "standard" vs paid support tiers |
| Security & compliance | SSO, SCIM, data residency, retention policies | Bring InfoSec requirements to the first sales call |
| Professional services | Implementation, training, managed experimentation | Budget 35–50% above license for year-one TCO |
| Contract length | Multi-year deals may unlock discounts; shorter terms may cost more per year | Model 1-year vs 3-year TCO before negotiating |
What you actually pay for
Even without an official price sheet, Optimizely quotes typically include line items like:
- Platform license — base fee for selected products (Web Experimentation, Feature Experimentation, etc.)
- Traffic / impression allotment — contracted cap; overages or upgrades if exceeded
- Add-on modules — personalization, analytics integrations, Opal AI credits (metered in some 2025+ bundles per DXP Scorecard)
- Seats / workspaces — team access, role-based permissions, sandbox environments
- Support tier — standard vs premium, response-time SLAs
- Implementation services — partner-led or Optimizely-led onboarding, training, experiment program design
Treat the license fee as a floor, not the full year-one cost. Buyer guides consistently warn that services, overages, and internal headcount push total cost of ownership well above the quoted platform number.
How to get an accurate Optimizely quote
- Inventory your traffic — monthly unique visitors, pages to test, peak seasons, international traffic splits
- Define scope — web-only A/B tests vs feature flags vs CMS/DXP bundle; list must-have integrations
- Document security needs — SSO, data retention, GDPR/CCPA, sandbox vs production separation
- Set a team plan — seats, roles, who runs experiments, whether you need managed services
- Request itemized pricing — separate license, traffic tier, modules, support, and services
- Clarify overages & renewal — impression overage rates, auto-renewal notice period, price escalation caps
- Compare TCO, not sticker price — include implementation, training, and internal ops time

"Optimizely" now means several different products
A lot of pricing confusion comes from the name covering more than one thing. Optimizely acquired Episerver in 2020 and later took its name, so searches for Episerver CMS pricing and Optimizely CMS pricing land on the same product line. Each SKU is quoted separately:
| Product | What it is | Reported annual cost |
|---|---|---|
| Web Experimentation | Client-side A/B testing — what most marketers mean | $36,000–$80,000+ |
| Feature Experimentation | Server-side flags and experiments | $50,000–$120,000+ |
| Rollouts | Feature flagging, free tier available | $0 on the free tier |
| CMS (formerly Episerver) | Content management / DXP | Quoted per deployment; typically the largest line item |
| Personalization / Commerce | Add-on modules | Roughly doubles contract value each |
If you only need client-side A/B testing, make sure your quote is for standalone Web Experimentation. Bundled DXP quotes are the main reason buyers report six-figure numbers for what they thought was a testing tool.
Optimizely vs alternatives: what changes TCO
If you searched "Optimizely pricing," you are likely comparing budget, contract flexibility, and time-to-value — not just feature checklists.
| Dimension | Optimizely | Typical mid-market alternative |
|---|---|---|
| Price transparency | Sales-gated; no public list price | VWO, Convert publish tiers; Stellar publishes Free + Pro pricing |
| Entry cost (reported) | ~$36,000+/year minimum estimates | Stellar Free (25k MTU); VWO Growth from ~$314/mo annual |
| Billing | Annual / multi-year contracts | Stellar offers monthly or annual; some vendors offer monthly |
| Script weight | Heavier enterprise tag | Stellar ships a 5.4KB async snippet (lightweight testing) |
| Best fit | Enterprise DXP + experimentation programs | Teams needing fast setup, clear pricing, or performance-first testing |
A note on PostHog vs Optimizely pricing, since the two get compared often: PostHog bundles experimentation into a usage-priced analytics platform with a free tier, which makes it attractive for product teams already wanting session replay and analytics. It is an engineering-first tool, though — the comparison is really "developer platform with experiments included" versus "marketer-first visual testing." If you want the second without enterprise contracts, that is the gap Stellar fills.

What Optimizely customers say about pricing
User reviews on G2, TrustRadius, and community threads often echo the same themes:
- High entry cost — the ~$36k+ floor excludes many SMBs
- Opaque metering — impression caps and overages are not always clear upfront
- Bundle pressure — features spread across tiers/products; upgrades to unlock basics
- Auto-renewal friction — missed cancellation windows leading to another annual cycle
- Value vs. usage — paying for capacity or modules not fully utilized
These are anecdotal buyer experiences, not official Optimizely policy. Use them as diligence prompts when reviewing your quote.
FAQ
Does Optimizely have a free plan?
Partly, and the distinction matters. Optimizely Rollouts, its feature-flagging product, has a genuinely free tier. But Web Experimentation — the client-side A/B testing product most marketers are shopping for — has no free tier, no self-serve paid tier, and no public trial. Evaluating it requires a sales conversation and an annual contract. Stellar offers a free tier for A/B testing itself, up to 25,000 MTU.
How much does Optimizely cost per month?
Optimizely does not sell monthly, so the honest answer is your annual contract divided by 12. On reported 2026 figures that works out to roughly $3,000/month at the $36,000 entry point and $6,500/month at the $80,000 small-deployment ceiling — but you cannot pay that way, and you cannot cancel mid-term.
Is there an Optimizely pricing calculator?
No. There is no public Optimizely pricing calculator. Every SKU on Optimizely's plans page routes to sales. Use the four-step estimate above, then validate against a written quote.
How much does Optimizely A/B testing cost?
For standalone Web Experimentation, third-party 2026 reports commonly cite $36,000–$80,000/year at smaller traffic bands. That is the SKU most marketers mean by "Optimizely A/B testing." Quotes that include CMS, Personalization, Commerce, or Feature Experimentation are a different product and a different budget.
Is Optimizely priced by impressions or MTUs?
Primarily monthly tracked users (MTUs) in 2026 — unique visitors who hit a page running an active experiment in a calendar month. Older contracts and some SKUs still meter on impressions. This matters because buyers consistently underestimate MTU consumption: one experiment on a high-traffic homepage can exhaust a small-tier allowance in days. Confirm which meter your quote uses and what the overage rate is.
How do I estimate my Optimizely cost before talking to sales?
Start from monthly unique visitors on the pages you actually intend to test, not sitewide traffic. Under 250,000 MTUs puts you in the reported $36,000–$80,000 band, 250,000–1M in the $80,000–$150,000 band, and above 1M in the $150,000+ band. Then add 35–50% for year-one implementation, training, and staffing. Each additional module roughly doubles the contract. See the four-step estimate above.
What discounts can you negotiate on Optimizely?
Reported buyer data points to 20–30% off for multi-year terms and 25–35% for bundling multiple products, with more leverage at the end of Optimizely's fiscal quarter. Negotiate a price-escalation cap on renewal at the same time — uncapped renewal increases are a common complaint.
Is Optimizely worth it for mid-market teams?
It depends entirely on whether you need the DXP. If you want client-side A/B testing and nothing else, a $36,000+ annual commitment buys capability most mid-market teams will not fully use, and the 35–50% year-one services uplift lands hardest on teams without a dedicated experimentation function. If you are standardizing CMS, commerce, personalization, and experimentation on one vendor, the bundle economics change and the conversation is different.
Do Optimizely contracts require annual commitment?
Yes. Optimizely is sold through custom annual or multi-year contracts. Monthly billing is not publicly offered. Buyer reports also mention auto-renewal clauses — confirm notice windows and cancellation terms before signing.
What is the cheapest Optimizely plan?
There is no published cheapest plan. Third-party buyer reports commonly cite a minimum entry point around $36,000 per year for basic web experimentation, but your quote depends on traffic, modules, support tier, and negotiation. Contact Optimizely sales for an exact number.
What affects an Optimizely quote the most?
Traffic or impression volume, which products you bundle (Web Experimentation, Feature Experimentation, CMS, Personalization, etc.), support/SLA level, security requirements (SSO, data residency), and professional services for implementation. Bundling multiple SKUs typically raises total contract value significantly.
How does Optimizely pricing compare to Stellar, VWO, and Convert?
Optimizely is enterprise-oriented with sales-gated, annual contracts often starting in the tens of thousands per year. Stellar publishes transparent tiers (free up to 25k MTU; Pro from $99/mo billed annually) with a lightweight script. VWO and Convert publish more accessible entry pricing than Optimizely, though enterprise tiers on those platforms can also scale up with traffic and features.
