CardSort vs Maze: Which Tree Testing Tool Should You Choose?

Maze restricts tree testing to its Enterprise tier with custom pricing, while CardSort offers tree testing free with unlimited studies and participants — making CardSort the only practical option for teams without an Enterprise contract. If you're searching for tree testing in Maze and finding yourself blocked behind a "contact sales" wall, CardSort solves that problem in under 10 minutes.

Key Takeaways

  • Maze gates tree testing: Tree testing is not available on Maze's Free, Starter ($75/mo), or Organization ($350/mo) plans — only Enterprise (custom pricing) includes it
  • CardSort tree testing is free: Unlimited studies, unlimited participants, no sales call required
  • No contract commitment: CardSort works without procurement cycles, Enterprise contracts, or annual commitments
  • Faster setup: Most tree tests launch on CardSort in 10-15 minutes vs. weeks of procurement on Maze Enterprise
  • Best fit: Choose CardSort for any team without an existing Maze Enterprise contract

Quick Summary

Maze is a comprehensive UX research platform that includes tree testing only on its Enterprise tier. The Free, Starter, and Organization plans cover prototype testing and surveys but exclude tree testing entirely. CardSort is purpose-built for information architecture research and offers tree testing as a free first-class feature alongside card sorting and surveys.

The Maze Tree Testing Paywall

Maze's pricing structure puts tree testing out of reach for the vast majority of teams. Here's where each tier lands:

Maze PlanMonthly CostTree Testing
Free$0Not included
Starter$75Not included
Organization$350Not included
EnterpriseCustomIncluded

To get tree testing on Maze, you need to:

  1. Contact Maze sales
  2. Sit through discovery and demo calls
  3. Negotiate an annual Enterprise contract (typically tens of thousands per year)
  4. Wait for procurement and legal review
  5. Onboard your team

For a research method that most teams use periodically — to validate a navigation redesign every 6-12 months — this commitment rarely makes sense. Tree testing is a checkpoint, not a daily workflow.

Pricing Comparison

CardSort's pricing model is the opposite of Maze's: tree testing comes free, with no participant caps, no study limits, and no contracts. Pro and Enterprise tiers exist for advanced features like white labeling and custom branding, but core tree testing is always free.

CardSort

  • Free: Unlimited tree tests, unlimited participants, no sales call
  • Pro: $29/month — White labeling, advanced analytics
  • Enterprise: Custom pricing — SSO, dedicated support

Maze

  • Free: 1 active test, up to 10 responses, no tree testing
  • Starter: $75/month — 5 active tests, 100 responses, no tree testing
  • Organization: $350/month — Unlimited tests, 300 responses, no tree testing
  • Enterprise: Custom pricing — Tree testing included

Winner: CardSort by a margin of "free vs. Enterprise contract." There is no comparable tier on Maze.

Tree Testing Features

Both tools support the core tree testing workflow when you can access them: define a navigation hierarchy, create tasks, recruit participants, and analyze success rates and paths. CardSort's tree testing is feature-complete for the vast majority of IA research:

FeatureCardSortMaze (Enterprise)
Tree test creation
Task-based testing
First-click analysis
Path analysis
Success rate scoring
Directness scoring
Unlimited participantsPlan-dependent
Real-time results
CSV export
Available on free tier
No contract required

The functional gap is small. The pricing gap is enormous.

What Maze Enterprise Offers That CardSort Doesn't

Maze's Enterprise tier includes integration with their broader UX testing platform — useful if your organization is already invested in that ecosystem.

  • Prototype testing — Test Figma, Sketch, Adobe XD designs
  • Live moderated interviews — Schedule and run sessions in-platform
  • First-click tests on prototypes — Test designs before they're built
  • Mission-based test sequencing — Combine multiple methods into a single participant flow
  • Enterprise SSO and admin controls — SAML, SCIM, audit logs

Maze Enterprise makes sense for teams running 5+ different research methods monthly with budgets in the $30k-$100k+ annual range.

What CardSort Offers That Maze Doesn't

CardSort focuses on accessibility and integration with adjacent IA methods. The free tier is the differentiator: every team can validate their navigation without procurement cycles.

  • Free tree testing — Zero cost, no Enterprise contract required
  • Unlimited participants — No response cap on the free plan
  • Card sorting integration — Run a card sort to generate the tree, then test it in the same workspace
  • Survey integration — Add pre/post-test questions in one flow
  • No participant accounts — Participants take tests via a shareable link without signing up
  • AI test responses — Generate synthetic responses to validate tasks before real recruitment

CardSort makes sense for solo researchers, small teams, agencies, and anyone who needs tree testing as one method among several rather than a full-platform commitment.

Setup Speed

Time-to-first-test is where the gap shows up most concretely.

CardSort:

  • Sign up free → ~30 seconds
  • Create a tree test from scratch → 5-10 minutes
  • Share participant link → instant
  • Total: under 15 minutes

Maze (Enterprise):

  • Contact sales → 1-3 days for response
  • Discovery call → 1-2 weeks
  • Demo and pricing → 1-2 weeks
  • Procurement and legal → 2-6 weeks
  • Onboarding and team training → 1-2 weeks
  • First test setup → 30-60 minutes
  • Total: 6-12 weeks

If you have a navigation redesign on the calendar, the Maze procurement timeline often outlasts the project itself.

When to Choose Each Tool

Choose Maze Enterprise if:

  • Your organization already has an Enterprise contract with Maze
  • You run 5+ research methods monthly and want them in one platform
  • You have budget approval for $30k+ annual research tooling
  • Your procurement timeline allows 6-12 weeks for new tools

Choose CardSort if:

  • You need tree testing without a sales call
  • You're a solo researcher, small team, or agency
  • You want to validate IA on a project-by-project basis
  • You need card sorting and tree testing in the same workspace
  • Your budget for tree testing is closer to $0 than $30k
  • You'd rather start testing today than 12 weeks from now

How to Switch from Maze Tree Testing to CardSort

If you're stuck on Maze's tree-testing paywall, switching to CardSort takes about 15 minutes:

  1. Sign up free at validatethat.io — no credit card, no sales call
  2. Create a new tree test from your dashboard
  3. Paste your navigation hierarchy — supports indented text format or CSV
  4. Define your tasks — the same tasks you'd use in Maze
  5. Share the participant link — no participant accounts needed
  6. Watch results in real time as participants complete tasks

The CardSort tree testing interface follows the same conventions as Maze, Treejack, and other major tools — your team won't need retraining.

The Bottom Line

If you're searching for "Maze tree testing" and discovering it's gated behind Enterprise, you have two real options:

  1. Commit to a multi-month, multi-thousand-dollar Maze Enterprise contract for a feature you'll use periodically
  2. Use CardSort tree testing free, today, in 15 minutes

For most teams, the second option is the obvious one. The first makes sense only when tree testing is a small part of an existing Enterprise commitment.

Frequently Asked Questions

Does Maze offer tree testing on its standard plans?

No. Tree testing on Maze is restricted to the Enterprise tier with custom pricing. The Free, Starter ($75/month), and Organization ($350/month) plans do not include tree testing.

Is CardSort really free for tree testing?

Yes. CardSort's free plan includes unlimited tree tests, unlimited participants, real-time results, and CSV export. There is no sales call and no time-limited trial.

Can I run tree testing and card sorting in the same study on CardSort?

Yes. CardSort lets you build IA via card sorting, then validate the resulting structure with a tree test — both in the same workspace, both free.

How does CardSort tree testing compare to Treejack?

Treejack (part of Optimal Workshop, $99/month) is the longtime leader in tree testing. CardSort matches Treejack's core feature set — task-based testing, path analysis, success rates, directness scoring — at zero cost. See our CardSort vs Treejack comparison for full details.

What's the participant experience like?

Participants click a link, optionally answer pre-test questions, complete tasks by clicking through the navigation tree, and optionally answer post-test questions. No account required. Mobile-optimized.
