Xnurta is built for ad ops across retail networks: Amazon, Walmart, Criteo. If Amazon is your whole fight, Astra is built for exactly that seat — full-funnel strategy across every ASIN, executed automatically, backed by expert strategy. Specialists win the ground they specialize in.
Xnurta includes monthly check-in calls on its Lead plan. Astra's human layer is on demand instead of on a cadence: an account rep with unlimited strategy calls, available from the free trial onward, staffed by operators who have scaled brands of their own.
Annual terms with agreed minimums mean paying while you wait to be convinced: Xnurta's Lead plan runs $750 a month or 3% of ad spend on yearly terms. Astra bills monthly, charges a subscription plus a percentage of ad revenue instead of spend, and is optimizing the same day you connect it. The results argue for the renewal, not the contract.
Account-level efficiency is not the same thing as product-level strategy. Every ASIN in Astra carries its own goal, Profit, Sales or Visibility, and the engine works each one daily — a launch and a bestseller stop sharing one target. On a 10,529-SKU catalog that looks like 17.8% ACOS on minutes a week.
Each one is a published case study, not a testimonial.
Astra Sellrbox makes Amazon ads feel simple. I don't have to overthink anything. The tools make campaign setup easy enough for a normal person to understand, and once your goals are clear, the AI takes over and handles the rest.
Works as advertised. The software is intuitive and easy to learn, and I got started quickly. I am pretty much hands off asides for the occasional checking of my performance and to adjust my budget and targets.
Sellrbox has been a great ecommerce partner and has grown our Amazon and Tiktok Shop accounts tremendously. We have increased our audience reach twofold and have lower ACOS and TACOS overall.
Responsive and very knowledgeable about Amazon and Walmart policies, especially on navigating 2024 fees. Helped us ~2x our sales through PPC + listing optimization. They definitely know their stuff.
Sellrbox is gold standard. They are responsive and understand all the nuances of the major etailer platforms to help ensure success and grow your brand.
We have automated our Amazon PPC spend, dropped our agency completely saving us about 95% of what we were spending, and doubled our sales in the last few months. I cannot express how grateful I am.
I'm a new Amazon seller, and learning how to manage ads on my own has been very challenging. I came across Astra and they've really helped me optimize my ads by significantly lowering my ACOS! My business is finally becoming profitable.
Sellrbox helped grow my amazon account from just under $1,000 in sales per month to over $5,000+ per month, really made my dreams a reality and showed me that making money online is very real and possible.
I've tried Teikametrics and Perpetua but they really don't work that well for advertising. Astra actually did what it was supposed to and scaled up my ads with AI. We moved our entire Amazon + Walmart management to the Sellrbox team.
I find the platform easy to use. There is a P&L section that succinctly describes my profitability which was an insanely manual task before. Support is great, they are reachable and proactively offer to help. Sales keep growing and can't complain.
We've seen a noticeable boost in profitability since using Astra. The automation features make campaign management effortless, and their customer support goes above and beyond. Perfect for teams that want to streamline ad performance and scale efficiently.
I was looking for a way to quickly scale my business across multiple platforms without expanding my team, and Sellrbox has been the perfect agency. They have in-house automation softwares that made managing ads so much easier.
Sellrbox worked out well for my brand, I was hesitant at first but they quickly showed that they were experts in the ecommerce world. Would work with them again!
Three steps, nothing to migrate by hand, nothing to turn off.
No annual terms stand between you and testing this: start the 30-day free trial, no credit card, and give Astra part of the catalog while Xnurta keeps the rest. Our longest published side-by-side ran more than a year before the account moved over fully.
Start the free trial →A free advertising audit comes first if you want it: an analyst reviews the account and shows you the opportunities they see. No commitment, no minimums, just the findings.
Book the free audit →On connection Astra ingests up to 24 months of campaign history, so what your account has already learned informs its first decisions. It builds the structure itself and is optimizing the same day, not weeks later.
Our comparison promise
Every claim about Xnurta on this page links to its source, most of them Xnurta's own pages, checked September 2026. If we got something wrong, tell us and we will correct it.
Yes, and what differs is the operating model, mostly. Xnurta is a multichannel ad platform (Amazon, Walmart, Criteo) sold on annual terms with agreed minimums, aimed at bigger programs and agencies. Astra is Amazon-only software on a monthly subscription that runs the entire PPC workflow itself, with a goal per product. Platform program versus engine you switch on.
Usually one of three structural reasons: monthly billing instead of annual terms with minimums, a fee on ad revenue instead of 3% of spend, and per-ASIN goals instead of program-level ops. None of that says Xnurta is bad at what it is built for; it says the two tools are built for different operators. The trial exists so you can check which one you are.
Xnurta's Lead plan is $750 a month or 3% of ad spend, up to $80K in monthly spend, billed annually with agreed minimums, and Enterprise is custom (their published pricing, September 2026). Astra is a monthly subscription plus a percentage of ad revenue: Explorer at $149 plus 1.75%, Professional from $299 plus 1.65% or 1.55%. No annual commitment is required, and annual billing is a 20% discount rather than a requirement.
No, and the contrast matters here: Xnurta's Lead plan can be priced at 3% of ad spend, while Astra's fee is a monthly subscription plus a small percentage of ad revenue. Spend-keyed pricing grows whenever spend grows; revenue-keyed pricing grows only when the ads produce.
No. Amazon Seller Central, in 16 Amazon marketplaces, is the whole surface Astra works. If Walmart or Criteo's retail network is a core channel for you, Xnurta covers ground Astra does not, and this page says so plainly.
No. Astra runs month to month, with a 20% discount if you choose annual billing, and you can change plans whenever you want. The 30-day trial needs no credit card.
The same day. You connect Seller Central, give each product a goal, and Astra ingests your trailing 24 months of campaign data, builds the structure and starts its optimization cycles. There is no multi-week onboarding project.
Yes. Every account, from the free trial up, gets an account rep and unlimited strategy calls with operators who have scaled brands of their own — not a check-in cadence that changes with your tier.
Same day to start, weeks to show. Astra begins its optimization cycles the day you connect, and the published accounts are the honest reference: SpitJack's sales rose 41% inside 30 days, while the rtunes side-by-side ran a full year on its way to 19.4% versus 51.7% ACOS. What disappears immediately is the manual workload.
The published case studies on this page include a 10,529-SKU account and a 22,000+ ASIN account, each with the hours involved. What Astra does not offer is white-labeling; if that is the requirement, Xnurta's agency tier is the better match.
