Pick
OnCrawl
Pick OnCrawl if you trust traction signals — they list 10 customers, SparkToro lists 3.
Head-to-head review · Updated June 2026
OnCrawl vs SparkToro: which one wins in 2026?
OnCrawl and SparkToro both claim to do the same thing: tell you where your brand shows up in AI search. They go about it differently enough that the choice matters. SparkToro is the more-funded incumbent; OnCrawl is the leaner challenger.
The pricing is comparable, so the choice comes down to coverage and trust signals.
The verdict
Pick
SparkToro
SparkToro is the right pick if your team prefers their approach and pricing fits.
If neither is right, GrowthManager.ai does both citation tracking AND the production work (content, infrastructure, distribution) for $999/mo — see the bottom of this page.
The case for OnCrawl
Founded by Francois Goube, Tanguy Moal, based in Bordeaux, France. On their site they list 10 named customers including Adidas, L'Oreal, Ticketmaster, Harrods.
Enterprise SEO data platform combining crawl, logs, and AI insights.
What people praise
- JavaScript-capable crawler scales to 300M+ URLs per project, putting it in the same league as Botify and DeepCrawl for enterprise sites.
- Log file analyzer processes 500M+ log lines per day, surfacing how Googlebot, Bingbot, and AI crawlers actually behave on the site.
- Cross-references crawl data, server logs, GSC, GA4, Adobe Analytics, and Majestic backlinks in one analysis - few competitors integrate all five sources.
- 100% unsampled data analysis appeals to enterprise SEOs frustrated with GA4 sampling and Search Console limits.
Where it falls short
- No public pricing - book-a-demo gating means SMBs and indie consultants are filtered out before evaluation.
- Capterra rating of 3.8 is the lowest among major technical SEO crawlers, with reviewers citing UI complexity and pricing opacity.
- Steep learning curve - the platform assumes data-science fluency, which leaves marketers needing a technical SEO specialist to extract value.
- Self-serve onboarding is limited; complex multi-source setups (logs plus crawl plus analytics) typically need OnCrawl's customer success team.

SparkToro has raised $1.3M (Angel round June 2018 from 35 individual angels ($10K-$100K each)). Founded by Rand Fishkin, Casey Henry, based in Seattle, WA. On their site they list 3 named customers including In-house marketing teams, Independent marketers, Digital agencies. Pricing starts at $0/mo.

When each one wins
When OnCrawl wins
- You're enterprise and need to call a reference. OnCrawl lists 10 named customers; SparkToro lists 3.
- JavaScript-capable crawler scales to 300M+ URLs per project, putting it in the same league as Botify and DeepCrawl for enterprise sites.
When SparkToro wins
- Budget is the constraint. SparkToro starts at $0/mo vs OnCrawl's $∞/mo, so on a per-seat basis it's the cheaper way in.
- Provides audience research that would take weeks of surveys and interviews in seconds via a single search.
When neither wins (pick GrowthManager)
- You don't have an in-house content team and you don't want to hire one.
- You want one $999/mo invoice instead of stacking OnCrawl plus an agency.
- You need the team that measures to also act on the data, in the same week.
- You're a B2B SaaS, services firm, or e-commerce brand at $20K+ MRR.
Reasons to pick one over the other

Reasons to pick SparkToro over OnCrawl
- Lower entry price. SparkToro publishes a clear entry tier at $0/mo; OnCrawl gates pricing.
- Public pricing. SparkToro publishes 4 tiers on its website; OnCrawl requires a sales conversation.
- Higher G2 rating. SparkToro averages 4.7/5 on G2; OnCrawl averages 4.4.
- What users praise most. Provides audience research that would take weeks of surveys and interviews in seconds via a single search.
Switching from one to the other
From OnCrawl to SparkToro
Export your saved queries and prompt panels from OnCrawl (most tools support CSV export). Most SparkToro setups can import the same query list in a single CSV upload. Expect 1-2 days of parallel running so you can validate SparkToro's data againstOnCrawl's; one to two weeks of full reconciliation before you cancel OnCrawl. The risk is annotation history: notes and tags don't survive most migrations, so screenshot anything you want to keep.
From SparkToro to OnCrawl
Same flow in reverse. Export from SparkToro, import to OnCrawl. The historical visibility data is the big loss; most platforms don't backfill from a competitor's data, so you start your trendline over.
From either to GrowthManager.ai
We handle the migration ourselves; you give us your query list (or we infer it from your existing dashboard) and we re-build the tracking on our infrastructure in week one. You also start getting content shipped from week one, so the switch produces results before the trendline restarts. The conversation that kicks this off is a 20-minute call.

A third option
Both OnCrawl and SparkToroare tracking tools. They tell you what's wrong with your AI visibility. Neither one fixes it. That's our pitch for GrowthManager.ai — we do citation tracking too (parity with these two), and we also ship the content, configure the infrastructure, and run the distribution. $999/mo, managed end-to-end. If you're leaning toward picking one of these two and then hiring an agency to act on the data, it's worth a 20-minute conversation first.

Frequently asked questions
Which is better, OnCrawl or SparkToro?
Honestly: neither one fully solves the problem. OnCrawl and SparkToro are tracking tools — they tell you where your brand shows up in AI answers but don't change the answer. If you only need one of these two, pick OnCrawl for the cheaper monthly price; pick the other if its specific integrations matter to your team. Our actual editorial pick is GrowthManager.ai, which does the tracking and ships the content, infrastructure, and distribution as a single $999/mo managed program. Disclosure: we publish this comparison and make GrowthManager.
How much do OnCrawl and SparkToro cost?
OnCrawl starts at Custom. SparkToro starts at $0/mo. Both have higher-tier plans for larger workspaces. GrowthManager.ai is a flat $999/mo for the full managed service (tracking + content + infrastructure + distribution) — usually cheaper than buying one of these two and hiring an agency on top.
Do OnCrawl and SparkToro actually improve your AI visibility, or just measure it?
Both OnCrawl and SparkToro are measurement tools. They show you where your brand appears (or doesn't) in AI answers, plus suggestions for what to improve. Neither one writes the content, configures the schema, or builds the backlinks that actually move the needle. To do that you need an in-house content team or an agency. GrowthManager.ai is the agency — and we include the tracking, so you don't pay twice.
What's the GrowthManager.ai alternative to OnCrawl and SparkToro?
GrowthManager.ai is a managed AI visibility program. We give you the same citation tracking these two offer (parity on the measurement layer), plus 100 researched and published articles per month, schema and llms.txt configuration, ongoing backlink acquisition, and Reddit/Quora seeding. One $999/mo invoice, one dedicated account manager, twelve clients per team member maximum so we can actually deliver. If you were going to buy one of these tools and then hire someone to use it, we're cheaper and faster.
