Head-to-head review · Updated June 2026
SISTRIX vs SpyFu: which one wins in 2026?
SISTRIX and SpyFu 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. SISTRIX has raised Bootstrapped, SpyFu has raised Bootstrapped; Both companies are roughly comparable in size; the choice comes down to price, coverage, and fit.
SpyFu is cheaper out the gate, but that's not the only thing that matters. The right pick depends on which dimension matters most for you.
The verdict
Pick
SpyFu
Pick SpyFu if you want the cheaper option ($39/mo vs $119/mo).
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 SISTRIX
SISTRIX has raised Bootstrapped. Founded by Johannes Beus, based in Bonn, Germany. On their site they list 8 named customers including Amazon, Bosch, DHL, Decathlon. Pricing starts at $119/mo.
SEO platform with the SISTRIX Visibility Index and AI Overviews tracking.
What people praise
- The proprietary Visibility Index is an industry-standard metric in the German-speaking SEO market, calculated from rankings across 1 million keywords per country with 13+ years of historical data.
- Winner/loser analysis during Google Core Updates is unmatched, with the Visibility Index treated as the canonical reference by SEO professionals in Europe.
- Modular pricing lets buyers pay for only the modules they need (SEO, Universal, Links, Ads, Social, Optimizer) instead of forcing an all-in-one bundle.
- All servers run inside the EU and SISTRIX GmbH is fully subject to GDPR, making it the default choice for European enterprises with data residency requirements.
Where it falls short
- Data depth is heavily skewed toward DACH (Germany, Austria, Switzerland) and Western Europe; US and APAC coverage is materially weaker than Ahrefs or Semrush.
- Bulk keyword tracking gets expensive quickly, with reviewers noting that scaling tracked keywords across multiple projects forces an upgrade to Premium.
- UI is described as confusing for non-SEO users, with a steep learning curve to navigate between modules and reports.
- Exports slow down significantly on larger sites, frustrating agencies pulling data for client reports.
The case for SpyFu
SpyFu has raised Bootstrapped. Founded by Mike Roberts, based in Scottsdale, AZ. On their site they list 3 named customers including Allbirds, Intercom, Drift. Pricing starts at $39/mo.
Competitor SEO and PPC research tool.
What people praise
- Years of competitor AdWords data, including ad copy and budget estimates, is the deepest historical PPC archive of any tool in this price range.
- Reviewers consistently call out affordability versus Semrush and Ahrefs, with the Basic plan starting at $39/mo.
- Unlimited domain overviews and data exports across all plans, which is unusual versus competitors who throttle exports.
- Kombat feature visualizes the keyword overlap between three competitors in a single venn-style chart that reviewers find useful for client decks.
Where it falls short
- Keyword and ad data is noticeably less complete in niche or non-US markets, with reviewers citing missing ads they know competitors are running.
- Backlink data is thin compared to Ahrefs or Semrush, so most users still need a second tool for link analysis.
- No real-time rank tracking; reviewers note the SEO rank data lags days behind actual SERP movements.
- Multiple Capterra and Trustpilot complaints about unauthorized auto-renewal charges and slow support response on billing issues.

When each one wins
When SISTRIX wins
- You're enterprise and need to call a reference. SISTRIX lists 8 named customers; SpyFu lists 3.
- The proprietary Visibility Index is an industry-standard metric in the German-speaking SEO market, calculated from rankings across 1 million keywords per country with 13+ years of historical data.
When SpyFu wins
- Budget is the constraint. SpyFu starts at $39/mo vs SISTRIX's $119/mo, so on a per-seat basis it's the cheaper way in.
- Years of competitor AdWords data, including ad copy and budget estimates, is the deepest historical PPC archive of any tool in this price range.
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 SISTRIX 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 SISTRIX over SpyFu
- More plan flexibility. SISTRIX offers 4 pricing tiers vs SpyFu's 3, so there's a better chance one fits your team size.
- More named customers. SISTRIX lists 8 customers vs SpyFu's 3, including Amazon, Bosch, DHL.
- What users praise most. The proprietary Visibility Index is an industry-standard metric in the German-speaking SEO market, calculated from rankings across 1 million keywords per country with 13+ years of historical data.
- EU data residency. SISTRIX is HQ'd in Bonn, Germany, which simplifies GDPR data-processor agreements for European buyers.
Reasons to pick SpyFu over SISTRIX
- Lower entry price. SpyFu starts at $39/mo vs SISTRIX's $119/mo.
- More verified reviews. SpyFu has 513 G2 reviews vs SISTRIX's 20, so the average rating carries more weight.
- What users praise most. Years of competitor AdWords data, including ad copy and budget estimates, is the deepest historical PPC archive of any tool in this price range.
Switching from one to the other
From SISTRIX to SpyFu
Export your saved queries and prompt panels from SISTRIX (most tools support CSV export). Most SpyFu setups can import the same query list in a single CSV upload. Expect 1-2 days of parallel running so you can validate SpyFu's data againstSISTRIX's; one to two weeks of full reconciliation before you cancel SISTRIX. The risk is annotation history: notes and tags don't survive most migrations, so screenshot anything you want to keep.
From SpyFu to SISTRIX
Same flow in reverse. Export from SpyFu, import to SISTRIX. 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 SISTRIX and SpyFuare 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, SISTRIX or SpyFu?
Honestly: neither one fully solves the problem. SISTRIX and SpyFu 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 SpyFu 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 SISTRIX and SpyFu cost?
SISTRIX starts at $119/mo. SpyFu starts at $39/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 SISTRIX and SpyFu actually improve your AI visibility, or just measure it?
Both SISTRIX and SpyFu 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 SISTRIX and SpyFu?
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.
