How we make this list: we compare pricing pages, product documentation and public user reviews. Ratings come from G2, Capterra or Trustpilot, with the date we checked them.
Programmatic advertising has a gatekeeping problem. The best platforms do not publish prices, do not offer self-serve signup, and expect you to arrive with either a skilled trading team or an agency that has one. The buying question is not "which DSP has the best UI" but "which seat can we actually sit in": direct enterprise contracts, agency seats, or the self-serve platforms built for smaller budgets.
The eight platforms below span that access ladder. Note two 2026 transitions as you read: Amazon DSP now lives inside Amazon Ads Agent, and Xandr's technology has been absorbed into Microsoft Advertising. Use current naming when you brief your team.
#1
The Trade Desk
Best for: Advertisers and agencies running serious programmatic budgets independently
Visit thetradedesk.com
Starting priceCustom quote (percentage-of-spend model; no public pricing)
Free planNo
The Trade Desk is the independent buy-side standard. Its value proposition is structural: unlike Google or Amazon, it does not own media, so its incentives align with advertisers. Inventory breadth covers CTV, audio, display, digital out-of-home, and more, with a data marketplace and measurement partnerships that support serious planning.
The operating model is professional. This is a pro tool; small teams usually access it through an agency seat rather than directly, and running it well requires traders who know what they are doing. Contracts run on percentage-of-media with minimums; confirm the fee structure and data costs separately, because data fees stack. If you spend enough to justify the seat and the talent, independence is worth it.
What we like- Leading independent DSP with broad omnichannel inventory across CTV, audio, display, and DOOH
- Objective buy-side-only positioning
- Strong data marketplace and measurement partnerships
Watch out for- Enterprise-grade minimums, not built for small budgets
- Needs skilled traders or a managed partner to run well
Starting priceCustom quote (no public pricing; enterprise minimums)
Free planNo
DV360 is the obvious choice for Google-centric organizations: planning, buying, and measurement unified in one platform, with native access to YouTube, Google audiences, and Analytics 360 data. For teams already paying for the Marketing Platform, the integration compounds.
The gravity is the caveat. DV360's best features assume you live in Google's stack, and independence from Google is limited by design; the industry's debates about Google's dual buy-side and sell-side roles are worth understanding before you commit. Setup is moderate with certified teams. Contracts are quote-based with platform fees; confirm minimums. Google shops should evaluate it first; everyone else should weigh the ecosystem lock-in.
What we like- End-to-end campaign management inside Google Marketing Platform
- Native YouTube and Google inventory plus third-party exchanges
- Tight Analytics 360 integration
Watch out for- Quote-based enterprise pricing with minimums
- Deepest value stays inside Google's ecosystem
Starting priceCustom quote (self-service and managed options; contact an account executive)
Free planNo
Amazon's programmatic offering is mid-rebrand: the vendor confirms Amazon DSP is now part of Amazon Ads Agent, with programmatic capabilities available in the platform's advanced settings. Verify current naming, access paths, and workflows in a demo before publishing plans or signing; transitions create confusion.
The underlying assets are unchanged and formidable: exclusive streaming inventory plus purchase-signal targeting no other DSP can offer, with closed-loop measurement to Amazon sales. For brands selling on Amazon, that combination is the reason to buy. Setup is moderate, with self-service alongside managed options. Pricing carries forward existing structures per the vendor FAQ; confirm details with an account executive.
What we like- Exclusive Prime Video, Twitch, Fire TV inventory and Amazon purchase signals
- Programmatic unified with sponsored ads
- Closed-loop measurement to Amazon sales
Watch out for- Product in transition to Amazon Ads Agent
- Verify current UI and workflows
- Quote-based pricing
#4
StackAdapt
Best for: Mid-market brands and agencies wanting many channels in one platform
Visit stackadapt.com
Starting priceCustom quote (no public pricing on the vendor site)
Free planNo
StackAdapt's appeal is breadth with accessibility: nearly every programmatic channel in one platform, with AI-assisted planning and an onboarding experience faster than the enterprise DSPs. Mid-market brands and agencies get enterprise-style reach without enterprise-style process.
More channels do not fix a weak media plan. The platform rewards experienced buyers who allocate deliberately; spread-too-thin budgets across eight channels underperform focused ones. Setup is light to moderate. Contracts are quote-based; confirm minimums and fee structure. For teams that know their media strategy and want it executed across channels efficiently, StackAdapt is the mid-market sweet spot.
What we like- Multi-channel: CTV, video, display, native, audio, DOOH, email, and direct mail
- AI-first planning and optimization
- Strong for mid-market
Watch out for- Quote-based pricing with no public tiers
- Channel breadth needs disciplined media planning
#5
Xandr (Microsoft Advertising)
Best for: Buyers wanting Microsoft inventory plus open-web programmatic
Visit xandr.com
Starting priceCustom quote (no public pricing on the vendor site)
Free planNo
Xandr as a standalone brand is ending: xandr.com now resolves to Microsoft Advertising, and the technology lives inside Microsoft's ad ecosystem. Use current naming in briefs and contracts, and confirm exactly which products your agreement covers.
What remains is substantive: programmatic buying technology plus Microsoft's owned inventory and an open-web marketplace, with publisher-side tools for the sell side. For buyers who want Microsoft properties alongside programmatic reach, the combination works. Setup runs moderate to heavy for enterprise deployments. Contracts are quote-based; confirm fee and minimum terms. Just do not brief your team on "Xandr" without checking what it is called this quarter.
What we like- Programmatic technology inside Microsoft Advertising's ecosystem
- Microsoft owned inventory plus open-web marketplace
- Publisher-side tools for the sell side
Watch out for- Brand being absorbed
- Confirm current product naming
- Fully quote-based
#6
Basis Technologies
Best for: Agencies drowning in manual media operations across channels
Visit basis.com
Starting priceCustom quote (no public pricing on the vendor site)
Free planNo
Basis sells operations, not just media. The platform unifies programmatic, search, social, and direct buying, but the differentiator is workflow automation: trafficking, approvals, and the automated billing reconciliation that anyone who has reconciled agency invoices by hand will immediately understand. Managed services are available alongside the platform.
The audience shapes the value. Agencies running multi-channel campaigns for many clients get the most from the operations layer; direct brands with one media plan may underuse it. Setup is moderate, with process mapping as the real work rather than technical integration. Contracts are quote-based; confirm platform versus managed-service pricing separately. If media operations overhead is your pain, evaluate Basis on the workflow demo, not the DSP demo.
What we like- Unifies programmatic, search, social, and direct buying with workflow automation
- Automated billing reconciliation
- Managed services available
Watch out for- Quote-based pricing
- Automation depth matters most to agencies
#7
Adform
Best for: European and global advertisers wanting an independent full stack
Visit site.adform.com
Starting priceCustom quote (no public pricing on the vendor site)
Free planNo
Adform is the independent full-stack alternative: DSP, data management, and ad serving from one vendor that does not own media. European advertisers value the regional presence and GDPR posture; the identity solutions address the cookieless reality pragmatically.
Regional strength is also the limitation. US buyers should validate inventory depth and support coverage before committing; the platform's center of gravity is Europe. Setup is moderate. Contracts are quote-based; confirm regional pricing and data fees. For global advertisers that want independence from the walled gardens with a vendor that takes privacy regulation seriously, Adform belongs on the shortlist.
What we like- Full-stack independent platform with DSP, DMP, and ad serving
- Strong European presence and GDPR posture
- Cookieless identity approach
Watch out for- Quote-based pricing
- Smaller US footprint than the biggest DSPs
#8
AdRoll
Best for: SMB and mid-market e-commerce brands wanting accessible retargeting
Visit adroll.com
Starting priceSee website (pricing page could not be fetched during research)
Free planUnverified (confirm on the vendor site)
AdRoll is the accessible end of programmatic: multichannel retargeting across display, social, and email with self-serve onboarding aimed at smaller teams. SMB and mid-market e-commerce brands get retargeting running without an enterprise contract or a trading desk.
The research caveat is pricing. The vendor's pricing page could not be fetched during research, so confirm plan details, billing model, minimums, and contract terms directly on the vendor site before budgeting or publishing. The platform also lacks the depth of enterprise DSPs for large programmatic programs; that is the trade for accessibility. Setup is light. For straightforward retargeting at SMB scale, it does the job.
What we like- Accessible multichannel platform for display, social, and email retargeting
- Strong for SMB e-commerce
- Self-serve onboarding
Watch out for- Pricing could not be verified from the vendor page
- Less depth than enterprise DSPs

Frequently asked questions
How much does programmatic advertising cost?
Two costs: media spend and platform fees. Enterprise DSPs charge platform fees as a percentage of media with minimums, all quote-based. Data and measurement fees stack on top. Small teams should budget through agency seats or self-serve platforms like AdRoll; direct enterprise seats assume serious spend.
Do we need a DSP or will an agency do?
If programmatic is a core, ongoing channel with real budget, a direct seat plus in-house or contracted trading talent gives you control and transparency. If it is one channel among many, an agency seat on a major DSP is more cost-effective. The worst option is a direct seat nobody knows how to operate.
What is the difference between a DSP and a walled garden?
DSPs like The Trade Desk buy across the open web and position as neutral. Walled gardens (Google, Amazon) sell their own inventory with unmatched data. Most mature advertisers use both: walled gardens for their exclusive inventory and data, independent DSPs for open-web reach and objective measurement.
How do we evaluate DSP fees?
Ask for the take rate: platform fee as a percentage of media, stated separately from data, measurement, and managed-service fees. Confirm minimums and what happens below them. Get the renewal terms in writing. And ask which fees are pass-through versus margin; transparency here predicts transparency everywhere.
What happened to Xandr and Amazon DSP naming?
Xandr's technology has been absorbed into Microsoft Advertising; xandr.com redirects there. Amazon DSP is now part of Amazon Ads Agent. Both transitions were confirmed on vendor pages in October 2026. Use current naming in contracts and briefs, and verify the current UI in a demo.
Can small businesses use programmatic platforms?
Yes, through the accessible tier: AdRoll's self-serve retargeting, agency seats on major DSPs, or managed-service options. Direct enterprise DSP contracts assume budgets and expertise most SMBs do not have. Start with retargeting, prove the return, then expand channels.
How we chose
We started with the searches buyers actually run: best programmatic platforms and its variants. For each candidate we opened the vendor's own homepage, confirmed the 2026 product transitions on vendor pages, marked custom quote where no prices are published, and compared inventory access, pricing model, and buyer fit against practitioner discussion and public sources. Where a vendor page could not be verified, we said so rather than filling the gap.
