Entry and mid-tier pricing side by side
The figures below are from each vendor's public pricing page as of July 2026 and SerionFlow's current plan list. Prices change; treat this as a snapshot and check the vendor page before buying.
| Tool | Entry plan | Mid plan | What the entry plan buys |
|---|---|---|---|
| SerionFlow | Starter $49/mo ($39 annual) | Pro $129/mo ($103 annual) | 1 project, 15-draft launch batch, 30 new pages/month, GSC flywheel, own-domain publishing |
| Frase | Starter $49/mo ($39 annual) | Professional $129/mo ($103 annual) | One domain, briefs and content optimization; same feature set on every tier |
| Surfer | Essential $99/mo ($79 annual) | Scale $219/mo ($175 annual) | 30 Content Editor articles, 5 AI articles/month; AI Tracker is a $95/mo add-on |
| Search Atlas OTTO | Starter $99/mo | Growth $199/mo | 1 OTTO SEO project and 120 target keywords; extra sites cost $99/mo each |
| AirOps | Solo $199/mo | Pro $1,999/mo | ChatGPT visibility tracking only on Solo; nothing between the two tiers |
| Writesonic SEO AI Agent | Starter about $79–99/mo | Basic $199/mo | AI research and article writing; Gemini and AI Overviews tracking start on Basic |
The add-ons that change the total
Surfer sells AI Tracker, its AI-search brand monitoring, as a $95 per month add-on for 25 prompts on top of Essential or Scale. Search Atlas caps OTTO SEO by project count and charges $99 per month per additional site below the Agency tier. Frase runs the same feature set on every tier but charges $29 per month per extra seat on Professional and Scale. AirOps has no tier between Solo at $199 and Pro at $1,999, so outgrowing Solo is a tenfold step. Writesonic sells a separate Human + AI SEO Service from $2,000 per month that is a different product from its self-serve tiers.
SerionFlow prices by pages per month and projects: Starter $49 for 1 project and 30 pages, Pro $129 for 3 projects and 70 pages, Agency $399 for 10 projects and 150 pages. Annual billing lowers these to $39, $103, and $319. Bing Webmaster Tools, IndexNow, and AI-related query signals are included from Pro; there is no per-site add-on.
What each plan actually buys
A $49 plan from SerionFlow and a $49 plan from Frase buy different things. SerionFlow Starter includes opportunity research, a 15-draft launch batch, 30 review-first pages a month, own-domain publishing via Vercel or Cloudflare routing, a generated sitemap, and the weekly Search Console flywheel. Frase Starter includes briefs, content optimization, and an editor for one domain; you supply topics and publish through your CMS. Neither is better in the abstract; they are priced for different jobs.
- SerionFlow: research, drafting, hosting, and measurement for one domain per project.
- Frase and Surfer: content optimization and writing; you handle topics and publishing.
- Search Atlas OTTO: automation on an existing site, priced per project.
- AirOps: a workflow platform; the price buys flexibility and expects engineering time.
How to compare cost per published page
Take the monthly price at the tier you would actually need, add the add-ons your use case requires, and divide by the number of pages you will realistically review and publish per month, not the generation limit. A $129 plan that produces 50 reviewed pages costs about $2.60 per page; a $49 plan that produces 10 because topic selection and publishing are manual costs about $4.90 per page. Then add the cost of any developer time the publishing path needs.
For SerionFlow the arithmetic is simple because quotas are explicit: Starter at 30 pages is $1.63 per page at full use, Pro at 70 pages is $1.84, Agency at 150 pages is $2.66, with no add-ons for Bing or AI signals. The Free plan lets you scan your site and generate one private draft before paying anything.
Where SerionFlow is the more expensive option
If you only need content optimization for pages you already write, Surfer or Frase deliver that for the same or less, and SerionFlow's research and hosting are features you would be paying for and not using. If you have a developer and a dataset, a template generator or your own framework costs hosting only. SerionFlow's pricing is competitive when the job is the whole loop; it is not the cheapest way to buy any single piece of it.

Frequently asked questions
What is the cheapest programmatic SEO platform in 2026?
+
At entry, SerionFlow Starter and Frase Starter are both $49 per month, or $39 billed annually. They buy different things: SerionFlow includes research, own-domain publishing, and a Search Console loop; Frase includes briefs and content optimization for one domain. Free tiers exist for testing on both.
Why is AirOps so much more expensive?
+
AirOps is a workflow platform for AI content operations rather than a page generator. Solo at $199 per month includes ChatGPT visibility tracking only; Pro at $1,999 adds Perplexity, Claude, Copilot, and Gemini tracking. There is no tier between them, which is the main pricing risk for growing teams.
Does SerionFlow charge per site?
+
No. Plans are priced by projects and pages per month: Starter $49 for 1 project and 30 pages, Pro $129 for 3 projects and 70 pages, Agency $399 for 10 projects and 150 pages. Bing Webmaster Tools, IndexNow, and AI-related query signals are included from Pro without add-ons.
Which add-ons should I budget for with other tools?
+
Surfer AI Tracker at $95 per month for AI-search monitoring, Search Atlas at $99 per month per extra OTTO site below Agency, and Frase at $29 per month per extra seat on Professional and Scale. Writesonic's Human + AI SEO Service from $2,000 per month is a separate product.
How should I compare programmatic SEO pricing fairly?
+
Compute cost per reviewed, published page: monthly price at the tier you need plus required add-ons, divided by pages you will realistically publish, plus any developer time the publishing path requires. This exposes tools whose low sticker price hides manual topic selection or publishing work.
