Helium 10 vs SellerApp at a Glance (2026)
Both tools live in the same corner of the market — Amazon seller software — but they were built for different jobs. Helium 10 is a research suite: keyword and product research first, operations second. SellerApp leans the other way: advertising automation and listing/quality analytics first, research second. The price difference is smaller than most sellers expect, so the decision is usually about workflow, not budget.
| Feature | Helium 10 | SellerApp |
|---|---|---|
| Entry paid tier | Platinum $129/month ($99/month billed annually) | Pro from $99/month |
| Free tier | No free tier listed on the current pricing page; three paid tiers (Platinum / Diamond / Enterprise) | Yes — $0 Freemium plan, no credit card required |
| Top self-serve tier | Diamond $359/month ($279/month billed annually) | Smart Plan with Automation $149/month (list $250) |
| Above self-serve | Enterprise from $1,499/month, billed annually | Managed services and agency platform (quote-based) |
| Core strength | Keyword research (Cerebro / Magnet), product research (Black Box, X-Ray) | Advertising overview, campaign manager, PPC insights and ads automation |
| Best for | Sellers whose bottleneck is finding keywords and products | Sellers whose bottleneck is ad-spend efficiency |
Bottom line: if you are choosing between keyword data and ad automation, Helium 10 Platinum costs about 30% more than SellerApp Pro and buys you a deeper research stack; SellerApp Pro is cheaper and its free tier lets you test the platform before paying a cent. Plenty of sellers need neither immediately — run the numbers on your own margin first with the free FBA fee calculator before you commit to either.
What Helium 10 Costs in 2026
Helium 10's pricing page as of 22 September 2026 lists three tiers and no free plan:
- Platinum — $129/month, or $99/month billed annually (the page states a $360 annual saving). Positioned for brands doing up to roughly $100K in yearly sales.
- Diamond — $359/month, or $279/month billed annually (stated saving $960). Positioned at $100K–$10M in yearly sales and includes the Helium AI agent, rules-based ad automation and inventory / P&L reporting.
- Enterprise — from $1,499/month, billed annually, for brands above $10M.
Two practical notes. First, Diamond is the tier that unlocks ad automation and the AI agent — if automation is why you were looking at Helium 10, budget for Diamond rather than Platinum. Second, the annual discount is real but front-loaded: at $99/month billed annually you commit $1,188 up front, so make sure the tool earns its keep within a month or two. Older reviews still quote a discontinued "Starter" tier and a $99/month Platinum price; both are out of date.
What SellerApp Costs in 2026
SellerApp's pricing page on the same date lists a free plan plus two self-serve paid tiers:
- Freemium — $0, no credit card required, with basic product research and overview functionality.
- Pro — starts at $99/month, adding insights, keyword tracking, listing quality and email support.
- Smart Plan with Automation — $149/month (shown against a $250 list price), aimed at sellers who want ads automation, a quarterly business review and chat support.
The free tier is the real differentiator. It is a genuine way to check that the data covers your marketplace before you pay, and it is why SellerApp appears so often in "free Amazon seller tools" discussions. The trade-off is depth: at $99/month you are paying for analytics and ads tooling rather than for the largest keyword index, so match the feature list against the reports you actually use.
Where the Two Tools Diverge
1. Research depth vs advertising depth
Helium 10's reputation is built on keyword data — reverse-ASIN lookup, search-volume estimates and rank tracking. SellerApp's is built on advertising: campaign structure, bid insights and automation rules. If you already know what to sell and your problem is that ACOS keeps drifting, that is a SellerApp-shaped problem. If you do not yet know what to sell, or your listing copy is guesswork, that is a Helium 10-shaped problem.
2. Entry cost and commitment
SellerApp's free plan means your first month can cost $0; Helium 10's cheapest entry is $129/month, or $99/month on an annual commitment. Over a year that is roughly $1,188 versus $0–$1,188, which matters if you are still testing whether Amazon is the right channel for you.
3. Where the ceiling sits
Both vendors push you upward once you scale: Helium 10 to Diamond ($359/month) and then Enterprise; SellerApp to its Smart plan ($149/month) and, for agencies, a managed-service quote. Neither vendor's self-serve tier is designed to run a multi-brand operation, so plan for a step up in cost at some point either way.
Which One Should You Pick?
- Pick Helium 10 if keyword research, product discovery and rank tracking are the centre of your workflow and you are prepared to pay $129/month (or commit to $99/month annually) from day one.
- Pick SellerApp if advertising efficiency is the bottleneck, or if you want to start on a free tier and upgrade only once the reports prove useful.
- Pick neither yet if you are pre-launch. Paying $99–$129/month before you have a live ASIN is the most common way sellers burn money in their first quarter. Amazon's own Search Query Performance and Brand Analytics reports, plus a free fee calculator, will carry you through product selection.
