Head-to-head review · Updated June 2026

Linkup vs Sanity: which one wins in 2026?

Linkup and Sanity 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. Linkup has raised $13.2M, Sanity has raised $173M; Sanity is the more-funded incumbent; Linkup is the leaner challenger.

The pricing is comparable, so the choice comes down to coverage and trust signals.

The verdict
Pick

Linkup

Linkup is the right pick if your team prefers their approach and pricing fits.

★ Our pick
Pick

Sanity

Pick Sanity if you want the better-funded company ($173M).

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 Linkup

Linkup has raised $13.2M ($10M Seed (Feb 2026, led by Gradient)). Founded by Philippe Mizrahi, Denis Charrier, Boris Toledano, based in Paris, France. On their site they list 8 named customers including McKinsey & Company, Cohere, KPMG, EY. Pricing starts at $0/mo.

Search API used by AI agents — the data layer for retrieval-augmented LLM apps.

What people praise

  • Built specifically as an API for AI agents and LLMs, not retrofitted from a consumer search product
  • Licenses content from publishers and pays them on usage, so results are legal and citation-safe
  • Sub-second search latency is fast enough for real-time agent tool calls
  • Free tier ships 4,000 queries and startups can apply for $5,000 in credits

Where it falls short

  • Per-request pricing makes monthly cost hard to forecast for high-volume agents
  • Deep Research mode can cost up to $2.50 per call, expensive at scale
  • Not a visibility, SEO or content product, it is a raw search API and you build the workflow yourself
  • No G2 or Capterra reviews yet, the company only launched its API in late 2024

The case for Sanity

Sanity has raised $173M ($85M Series C led by Bullhound Capital, May 2025). Founded by Magnus Kongsli Hillestad, Even Westvang, Simen Svale Skogsrud, based in Oslo, Norway. On their site they list 10 named customers including Nike, Spotify, Figma, Burger King. Pricing starts at $0/mo.

Composable content cloud with real-time collaboration.

What people praise

  • Rated #1 headless CMS on G2 for four consecutive years thanks to multiplayer editing and real-time collaboration.
  • Sanity Studio is fully customizable in React code, giving developers more control than any visual CMS competitor.
  • GROQ query language and real-time Content Lake APIs are uniquely powerful for complex content models.
  • Visual Editing works across Next.js, Nuxt, Astro, and SvelteKit so frontend choice is not constrained.

Where it falls short

  • Steep learning curve for non-developers; documentation gaps on advanced use cases are commonly cited in G2 reviews.
  • Pricing scales aggressively with API calls and asset usage, making large content libraries expensive at runtime.
  • Vendor lock-in is real because content is tied to GROQ and the Content Lake schema, making migrations painful.
  • Requires developer involvement to set up schemas and Studio; not a click-to-publish tool like WordPress.

When each one wins

When Linkup wins
  • Built specifically as an API for AI agents and LLMs, not retrofitted from a consumer search product
When Sanity wins
  • You want the better-funded incumbent. Sanity has raised $173M, giving it more runway and shipping velocity.
  • Rated #1 headless CMS on G2 for four consecutive years thanks to multiplayer editing and real-time collaboration.
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 Linkup 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 Linkup over Sanity

  1. More plan flexibility. Linkup offers 4 pricing tiers vs Sanity's 3, so there's a better chance one fits your team size.
  2. Built for the LLM era. Linkup was founded in 2024, built around AI search from day one; Sanity dates back to 2015 and is retrofitting.
  3. What users praise most. Built specifically as an API for AI agents and LLMs, not retrofitted from a consumer search product

Reasons to pick Sanity over Linkup

  1. Better-funded incumbent. Sanity has raised $173M, giving it more runway and shipping velocity than Linkup ($13.2M).
  2. Faster product velocity. Sanity has shipped 5 public launches in the last year vs Linkup's 0.
  3. More mature platform. Sanity (founded 2015) has had more time to harden the product than Linkup (2024).
  4. Wider integration ecosystem. Sanity integrates with 12 tools; Linkup ships 7.
  5. What users praise most. Rated #1 headless CMS on G2 for four consecutive years thanks to multiplayer editing and real-time collaboration.

Switching from one to the other

From Linkup to Sanity

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

From Sanity to Linkup

Same flow in reverse. Export from Sanity, import to Linkup. 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 Linkup and Sanityare 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, Linkup or Sanity?

Honestly: neither one fully solves the problem. Linkup and Sanity 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 Linkup 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 Linkup and Sanity cost?

Linkup starts at $0/mo. Sanity 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 Linkup and Sanity actually improve your AI visibility, or just measure it?

Both Linkup and Sanity 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 Linkup and Sanity?

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.
