Helium 10 is the SellerApp alternative to pick when the job is an all-in-one Amazon seller suite: keyword research, listings, ads, and TikTok Shop sit on one bill. Jungle Scout is the better product-research and Cobalt-intel path; Catalyst dollars stay hidden on the public pricing page, with a 7-day money-back window instead of a trial. SellerApp still wins the cheapest self-serve paid floor that includes listing quality, if checkout is the live Pro card that starts at $99 per month, not the help article that still prints Pro-Lite at $39. Trends MCP wins live Amazon best-seller boards and an amazon keyword source for agents. It does not run PPC or rewrite listings.
Which SellerApp alternative fits each job?
Helium 10 takes the overall seller-suite job. The other rows win narrower jobs: Jungle Scout for product research and Cobalt-grade category intel, SellerApp for a $0 Freemium start plus listing quality at a $99 Pro floor, SmartScout for brand and seller maps, Keepa for euro-priced price and sales-rank history, Trends MCP for agent-readable Amazon boards.
Figures below were read from vendor pages on 16 September 2026. Jungle Scout Catalyst SKUs are not printed on the public pricing page, so that cell is left blank rather than guessed.
| Tool | Wins this job | Public floor (16 Sep 2026) | Agent access |
|---|---|---|---|
| Helium 10 | All-in-one seller suite | Platinum $129 monthly, $99 yearly (saves $360); Diamond $359 monthly, $279 yearly (saves $960); Enterprise $1,499 | Diamond: MCP included free up to 1,000 calls; pricing grid also lists an MCP add-on starting at $50/mo. Cursor JSON is URL only, OAuth, no headers |
| Jungle Scout | Product research and Cobalt intel | Catalyst dollars hidden; 7-day money-back on standard Catalyst plans | MCP is Cobalt-powered. Named clients: Claude, ChatGPT, Gemini, Copilot. Cursor is not named. No public Cursor JSON |
| SellerApp | $0 Freemium plus listing quality at $99 | Freemium $0; Pro starts at $99/mo; Smart Plan with Automation $149 vs $250 for the first 3 months | REST at https://api.sellerapp.com/sellmetricsv2/products with client-id and token. No public Cursor JSON |
| SmartScout | Brand, seller, and subcategory maps | Monthly Basic $49, Essentials $119, Business $299; yearly displayed as $29 / $99 / $239 per month. Extra user $49 on the first three tiers | Snapshot MCP on Business. Full Access MCP on the top tier, marked unavailable for Legacy plans. No public Cursor JSON |

Yearly cards $16 / $192, $39 / $468, $159 / $1,910 | Cursor JSON uses url, transport: "http", and a Bearer header against https://api.trendsmcp.ai/mcp. Default get_top_trends limit 25, max 200 |
SellerApp is not first because the query is alternatives to SellerApp, and Helium 10 still covers more of a private-label week (Cerebro-class keywords, listings, ads, TikTok Shop) than SellerApp's live cards. Trends MCP is last on purpose. An Amazon search-trend series is not a campaign manager.
Why SellerApp's help article still disagrees with checkout
The live self-serve grid on sellerapp.com/pricing.html and the help article sellerapp-pricing-plans describe two different products.
Checkout on 16 September 2026: Freemium $0 with no card; Product Intelligence, Advertising Overview, and Campaign Manager included; Listing Quality, PPC Insights, and Ads Automation marked as missing. Pro starts at $99 per month and adds Insights, Keyword Tracking, Listing Quality, and email support; Ads Automation is still marked as missing. Smart Plan with Automation starts at $149 per month against a $250 regular price for the first three months, and adds Ads Automation, a quarterly business review, and email plus chat. Dedicated account manager and custom development sit behind red X marks on that Smart card; they belong with the quote-only Custom Requirements column (data warehousing, product solution expert, priority VIP support).
The help article still lists Freemium $0, Pro-Lite $39 per month, and Professional $79 per month, with a 7-day trial on paid plans and tracked-product caps of 2 / 20 / 50 / 250-500. Those $39 and $79 figures are not on the live cards. Treat them as stale copy, not checkout.
Two other splits sit on the same site. The pricing FAQ says an annual plan saves 50% versus monthly; the help article says 25% in two places. Flag rows on the pricing page show 19 marketplaces (United States, Canada, Mexico, Brazil, Germany, Spain, France, Italy, Netherlands, Poland, Sweden, Turkey, United Kingdom, Saudi Arabia, UAE, Australia, India, Japan, Singapore). The agency FAQ on the same URL lists 15 names and drops Brazil, Poland, Sweden, and Turkey.
Refund copy conflicts too. The agency FAQ on the pricing page says a refund request to [email protected] is ticketed in 4-5 hours on a business day and credited in about 5-10 days via Stripe. The plan-cancellation help article says there is no refund if the next cycle already charged, no remainder-of-cycle refund, and no remaining-credits refund; access runs through the current cycle, then Freemium.
Agency pricing starts at $300 plus 0.5%–2.5% of Amazon ad spend, with no mandatory minimum duration and a stated 3-month preference. Listing optimization and creation starts at $200 per parent ASIN. AMS Growth starts at $750 per month. AMS Scale is talk-to-sales. API copy on the pricing page cites 31,000 sellers, monthly usage with a limit, and a 24-hour refresh. The Amazon Seller API page cites 5 million API requests per day, 2,200 API users, and 99% uptime. There is no public mcp.json.
What Helium 10 and Jungle Scout cost if SellerApp is the baseline
Helium 10's public grid on 16 September 2026 is Platinum at $129 monthly or $99 yearly (saves $360), Diamond at $359 monthly or $279 yearly (saves $960), and Enterprise at $1,499 on both toggles. Trust lines on that page: 4.5 million brands, $7B+ monthly Amazon GMV, 860K+ active Chrome extension users, 24+ marketplaces. Platinum includes 1 extra user; Diamond includes up to 5. Diamond Ads carry a 2% managed-spend fee. Freedom Ticket is included on named paid plans, or $997 standalone.
MCP is the messy part. The Diamond card says Helium 10 MCP is included free (up to 1,000 calls). The same feature grid lists MCP as an add-on starting at $50/mo. The MCP landing FAQ says the connector is available to Diamond customers at no additional cost. GitHub helium10/Helium10-MCP (fetched 16 September 2026) documents paste-ready Cursor JSON as url only, no headers, OAuth 2.1, API token not supported. The README names 32 tools across eight toolsets. The landing page still says 40+ MCP tools. Cursor is named on the landing FAQ; the GitHub README focuses on Cursor, Claude (Code and Desktop), and ChatGPT.
Jungle Scout's Catalyst SKUs are not on junglescout.com/pricing. What is printed: a 7-day money-back guarantee on standard Catalyst plans (email [email protected]), Starter limited to 1 user, extra Catalyst seats $49/month or $459/year, Brand Owner includes 3 users. Cobalt is demo-gated for businesses at $1M+ annual corporate revenue. Marketing lines on that page: 1 million+ global customers, 18x GMV coverage, 11 years of sales-estimate work, 600M+ products tracked across 24 categories. Catalyst geographic coverage is listed as 8 Amazon marketplaces; Cobalt as 19.
Jungle Scout MCP lives at /products/jungle-scout-mcp/. It is powered by Cobalt. Named clients are Claude, ChatGPT, Gemini, and Copilot. Cursor is not named. There is no public Cursor JSON. Existing customers are told to ask a CSM. The page cites 40,000 active seller engagements and tracking 18% of Amazon GMV. That is a Cobalt-class market-intel pipe, not a $99 self-serve PPC desk.
SmartScout's public monthly cards are Basic $49, Essentials $119, Business $299. Yearly cards display as $29 / $99 / $239 per month. Extra user $49 on Basic, Essentials, and Business. Snapshot MCP is on Business. Full Access MCP is on the top tier and marked unavailable for Legacy plans. No Cursor JSON is published. Extra-user copy on the comparison grid is $49, $49, $49, then Custom.
Keepa or Trends MCP when the job is Amazon data, not ads
Keepa is the price-history tool. Language-pack string _753 on 16 September 2026 lists two Pro billing cycles: 29 euro per month, or 290 euro per year billed as 12 months for the price of 10. MCP is separate from browser Pro. Docs at keepa.com/api-docs/mcp.html require an API subscription, host https://keepa.com/mcp, Streamable HTTP, Bearer key. Cursor JSON:
{
"mcpServers": {
"keepa": {
"url": "https://keepa.com/mcp",
"headers": { "Authorization": "Bearer YOUR_API_KEY" }
}
}
}
No transport key. claude.ai custom connectors cannot connect; OAuth is described as planned. Tool calls spend the same tokens as REST.
Trends MCP is the live-board and keyword-growth tool. It is not a seller suite. Public HTML pricing on 16 September 2026: Free $0, 100 requests/month, 90 days of history, top 10 trends, 24-hour board delay. JSON-LD monthly Starter $19, Pro $49, Business $199. Yearly toggle cards: Starter $16/month ($192 billed annually), Pro $39 ($468), Business $159 ($1,910), with "2 months free" on the toggle. Keyword alerts: Starter 10, Pro 50, Business 250. History caps on the cards: Starter 1 year, Pro 2+ years, Business full archive. Board depth: Free top 10, Starter top 25, Pro top 100 per feed, Business all top trends.
Two metering stories exist. The HTML pricing FAQ says one successful API or MCP call equals one request. llms.txt the same day says MCP get_top_trends costs 1 credit per 10 requested rows (max 10 credits per call) and REST is 1 request per call. Trial copy splits too: yearly cards say "$192/year after day 7"; the FAQ says the card is not charged until day 8.
Cursor config from llms.txt (the homepage copy-config omits transport):
{
"mcpServers": {
"trends-mcp": {
"url": "https://api.trendsmcp.ai/mcp",
"transport": "http",
"headers": { "Authorization": "Bearer YOUR_API_KEY" }
}
}
}
Amazon jobs use get_top_trends with type Amazon Best Sellers Top Rated or Amazon Best Sellers by Category (pass category; official names include Electronics, Home Kitchen, Toys Games), plus get_growth with source amazon and a product or category phrase. Default limit is 25, max 200. That is the Cursor MCP setup for trend boards. Helium 10's Cursor JSON is OAuth URL-only. Keepa's is Bearer without transport. SellerApp has no MCP snippet to paste.
For a seller who also wants TikTok and Google next to Amazon, the matching landing page is ecommerce product research. That still does not replace SellerApp Ads Automation.
FAQ
Is SellerApp cheaper than Helium 10?
On the live cards, yes at the first paid rung: SellerApp Pro starts at $99 per month, Helium 10 Platinum is $129 monthly or $99 yearly. Helium 10 Diamond ($359 monthly / $279 yearly) is the plan that includes MCP up to 1,000 calls. SellerApp's help article $39 / $79 ladder is still published and does not match checkout, so a $39 comparison is the wrong baseline.
Does SellerApp have an MCP server for Cursor?
No public Cursor mcp.json was on SellerApp's pricing or Amazon Seller API pages on 16 September 2026. The documented product API is REST: https://api.sellerapp.com/sellmetricsv2/products with client-id and token headers, data refreshed once every 24 hours. Helium 10, Keepa, SmartScout, Jungle Scout (Cobalt), and Trends MCP all advertise some MCP path. Only Helium 10, Keepa, and Trends MCP publish paste-ready Cursor JSON.
Which alternative replaces SellerApp PPC automation?
None of the $0–$99 research tools do. SellerApp itself gates Ads Automation behind Smart Plan with Automation at $149 per month (first three months versus $250). Helium 10 puts rules-based ads on Diamond, with a 2% managed-spend fee. Jungle Scout's native advertising platform is described on Cobalt, not on the public Catalyst cards. Perpetua-class retail-media desks are a different buy; they were not re-priced in this run.
Is Trends MCP a SellerApp alternative for listing optimization?
No. Trends MCP returns Amazon best-seller boards and amazon keyword growth. It does not score listings, write bullets, or connect to Seller Central. SellerApp Freemium omits Listing Quality; Pro at $99 includes it. Helium 10 and Jungle Scout remain the suite picks for listing work. Use Trends MCP beside a suite when the missing piece is a live board an agent can query.
Can a team keep Keepa and drop SellerApp?
Yes if the pain was price history, Buy Box, and sales-rank charts. Keepa Pro is 29 EUR per month or 290 EUR per year, with MCP on a separate API subscription. That drop does not replace SellerApp Campaign Manager, keyword tracking, or Ads Automation. Most sellers who leave SellerApp for Helium 10 or Jungle Scout still keep Keepa for history.
