Head-to-head review · Updated June 2026

Kagi vs Sitebulb: which one wins in 2026?

Kagi and Sitebulb 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. Kagi has raised ~$5.5M, Sitebulb has raised Bootstrapped; Kagi is the more-funded incumbent; Sitebulb is the leaner challenger.

Kagi 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

Kagi

Pick Kagi if you want the cheaper option ($0/mo vs $18/mo); and you want the better-funded company (~$5.5M).

Pick

Sitebulb

Pick Sitebulb if you want the cheaper option ($18/mo vs $0/mo); and you trust traction signals — they list 6 customers, Kagi lists 1.

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 Kagi

Kagi has raised ~$5.5M ($2.5M from 93 angel investors (2023-2024)). Founded by Vladimir Prelovac, based in Palo Alto, CA. On their site they list 1 named customers including 50,000+ individual paying members as of June 2025. Pricing starts at $0/mo.

Paid ad-free search engine with AI assistant.

What people praise

  • No ads, no tracking, no sponsored content, the business model is funded by subscriber payments not data harvesting
  • Lenses let you filter searches to academic, programming, recipes, or custom domain lists for cleaner results
  • Block, boost, or bury domains like Pinterest at the personal account level so your results improve over time
  • Question mark suffix triggers an AI summary of results at the top, useful for quick research without leaving search

Where it falls short

  • Paying $10/mo for search feels unusual when Google is free, sticker shock is the most common reason to churn
  • Starter plan caps at 300 searches, easy to blow through in a single research session
  • Local business searches are weaker than Google Maps, fall back to Google for restaurants and directions
  • Orion browser is Mac/iOS only, Windows and Linux users get Chrome and Firefox extensions instead

The case for Sitebulb

Sitebulb has raised Bootstrapped. Founded by Patrick Hathaway, Gareth Brown, based in Banbury, UK. On their site they list 6 named customers including Amazon, Mailchimp, Macy's, Yahoo. Pricing starts at $18/mo.

Desktop and cloud SEO auditing tool for agencies.

What people praise

  • 300+ prioritized SEO hints with severity scoring and clear fix explanations, considered best-in-class for visual audits.
  • JavaScript crawling is included at no extra cost on every tier, unlike Screaming Frog where JS rendering is a premium feature.
  • Only crawler offering both desktop (up to 500K URLs) and cloud (up to 10M URLs) so teams can scale from solo to enterprise.
  • Visual data presentation with charts and graphs is widely cited as the most intuitive in the technical SEO category.

Where it falls short

  • Resource-intensive on large sites; a 100K-page JS-rendered crawl can take 8-12 hours and consume 8GB+ RAM.
  • No keyword research, backlink analysis, rank tracking, or content optimization, so it must be paired with another tool.
  • ~0.20% market share vs Screaming Frog's 15.41% means fewer community tutorials and forum answers.
  • Desktop pricing is not visible on the public pricing page without selecting a currency, hurting buyer transparency.

When each one wins

When Kagi wins
  • Budget is the constraint. Kagi starts at $0/mo vs Sitebulb's $18/mo, so on a per-seat basis it's the cheaper way in.
  • No ads, no tracking, no sponsored content, the business model is funded by subscriber payments not data harvesting
When Sitebulb wins
  • You're enterprise and need to call a reference. Sitebulb lists 6 named customers; Kagi lists 1.
  • 300+ prioritized SEO hints with severity scoring and clear fix explanations, considered best-in-class for visual audits.
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 Kagi 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 Kagi over Sitebulb

  1. Lower entry price. Kagi starts at $0/mo vs Sitebulb's $18/mo.
  2. Better-funded incumbent. Kagi has raised ~$5.5M, giving it more runway and shipping velocity than Sitebulb (Bootstrapped).
  3. Faster product velocity. Kagi has shipped 6 public launches in the last year vs Sitebulb's 0.
  4. What users praise most. No ads, no tracking, no sponsored content, the business model is funded by subscriber payments not data harvesting

Reasons to pick Sitebulb over Kagi

  1. More named customers. Sitebulb lists 6 customers vs Kagi's 1, including Amazon, Mailchimp, Macy's.
  2. What users praise most. 300+ prioritized SEO hints with severity scoring and clear fix explanations, considered best-in-class for visual audits.
  3. EU data residency. Sitebulb is HQ'd in Banbury, UK, which simplifies GDPR data-processor agreements for European buyers.

Switching from one to the other

From Kagi to Sitebulb

Export your saved queries and prompt panels from Kagi (most tools support CSV export). Most Sitebulb setups can import the same query list in a single CSV upload. Expect 1-2 days of parallel running so you can validate Sitebulb's data againstKagi's; one to two weeks of full reconciliation before you cancel Kagi. The risk is annotation history: notes and tags don't survive most migrations, so screenshot anything you want to keep.

From Sitebulb to Kagi

Same flow in reverse. Export from Sitebulb, import to Kagi. 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 Kagi and Sitebulbare 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, Kagi or Sitebulb?

Honestly: neither one fully solves the problem. Kagi and Sitebulb 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 Kagi 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 Kagi and Sitebulb cost?

Kagi starts at $0/mo. Sitebulb starts at $18/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 Kagi and Sitebulb actually improve your AI visibility, or just measure it?

Both Kagi and Sitebulb 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 Kagi and Sitebulb?

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.
