Fullstory’s natural loop
Pattern to diagnosis
Signal → segment or journey → replay → technical and customer context → action.
Clarity’s natural loop
Page to visual evidence
Page or signal → heatmap or recording → filter or funnel → action.
Shared middle
Replay is meaningful overlap
Both support reconstructed sessions, heatmaps, identity, filters, signals, mobile coverage, and aggregate-to-session paths.

Replay, heatmaps, and investigation depth
Fullstory is better for testing behavioral hypotheses; Clarity delivers useful visual evidence with little procurement friction. Both reconstruct pages from captured data rather than storing literal video, and neither reveals intent.
| Investigation task | Fullstory | Microsoft Clarity |
|---|---|---|
| Find a pattern | Native Search events, elements, pages, properties, signals, sequences | Native Filter views and save compatible filters as segments |
| Open sessions | Native Open sessions from metrics, funnels, segments, journeys, or heatmaps | Native Open recordings from dashboard cards, heatmaps, funnels, or filters |
| Click evidence | Native Click maps and frustration signals in experience workflows | Native Click, area, and conversion heatmaps with dead and rage-click signals |
| Scroll evidence | Native Scroll maps and page analysis | Native Scroll heatmaps, subject to page and container limitations |
| Compare outcomes | Native Build segments or funnel cohorts, then inspect examples | Limited Filter converters or drop-offs and open evidence |
| Longitudinal analysis | Plan-dependent Retention Analysis and Journeys need qualifying packages | Limited Date ranges and nine-month heatmaps, not cohort retention |
| Sharing | Plan-dependent Sessions, comments, notes, Spaces, dashboards, alerts | Limited Recording links, labels, favorites, and project segments |
| Replay availability | Subject to captured-session allowance and the plan’s replay retention | Microsoft says tracked traffic is not sampled, but Clarity keeps at most 100,000 recordings per project per day, samples which recordings it keeps above that threshold, and may not provide a recording for every session |
| Heatmap scale | Package and capture allowance apply | Up to 100,000 page views per heatmap under current documentation |
| Research depth | Multi-signal, cross-functional investigation | Visual starting point with narrower export and reporting |
Example: a Reporting workflow loses repeat use
A fictional B2B team sees Reporting adoption fall. Clarity can expose pages, devices, dead clicks, funnel exits, and recordings. Fullstory adds sequences, cohorts, journeys, properties, and developer evidence.
| Step | Question | Clarity route | Fullstory route |
|---|---|---|---|
| 1. Signal | Where did use fall? | Dashboard, filter, or funnel | Metric, dashboard, funnel, or segment |
| 2. Segment | Which sessions match? | Filters, tags, saved segment | Events, properties, users, pages, sequences |
| 3. Observe | What happened in examples? | Recordings and heatmaps | Replay, heatmaps, and journey context |
| 4. Diagnose | What else explains it? | Recording diagnostics | Console, exceptions, network, performance |
| 5. Validate | Is it prevalent? | Recheck filters, funnels, heatmaps | Compare cohorts, metrics, journeys, sessions |
Five steps, and the sequence is not proof of cause
1
Report-completion signal
Completion is down against a stated period and denominator
2
Eligible users, affected companies
Separate absence from ineligibility before reading anything as a decline
3
Matched visits
Successful and failed attempts viewed side by side, not failures alone
4
Validation
Prevalence, plus other evidence: server outcomes, tickets, what users said
5
Decide
Act, investigate further, or reject the hypothesis
Rejecting it is a real outcome
Matching failures against successes is what keeps step 3 honest. Watching only failures guarantees you find friction, whether or not it explains the signal.
No verified independent video met the evidence threshold. These official clips show positioning, not comparative performance.
Funnels, segmentation, and account context
Clarity answers straightforward page and event questions; Fullstory handles more complex segments. Clarity offers funnels, filters, shared segments, tags, and identity. Fullstory combines events, sequences, properties, pages, signals, metrics, and journeys.
Both can filter an instrumented account ID. Neither has a native B2B Company entity or ready-made unique-account denominator; prevalence may require grouped tables, exports, or external modeling. Tagged sessions are not unique companies.
Choose Fullstory
The cohort is part of the investigation
Use it when questions combine funnels, event order, properties, signals, and replay. Export entitlement varies by workflow, plan, and contract.
Choose Clarity
The question fits filters and simple funnels
Use it when pages, Smart Events, device, source, tags, or user IDs isolate the evidence.
Add account context
Neither is an account-adoption portfolio
B2B teams still need account adoption, lifecycle, commercial context, and user distribution.

Privacy, implementation, and retention
Fullstory has deeper governance; Clarity has sensible controls with fewer layers. Both require deliberate masking, consent, identity, access, and deletion. Neither price nor contract makes capture safe by default.
| Implementation area | Fullstory | Microsoft Clarity |
|---|---|---|
| Web installation | Browser capture snippet or supported integrations | Project tracking code or supported platform integration |
| Replay model | Reconstruction from page and interaction data | DOM and HTML reconstruction, not literal video |
| Console evidence | Native Console messages, warnings, errors, and exceptions | Not primary No comparable developer console workflow was verified |
| Network evidence | Native Enable capture and allowlist safe data | Not primary No comparable request inspector verified |
| Performance context | Limited Page and request timing in sessions | Limited Session context, not performance monitoring |
| Native mobile | Plan-dependent Paid Mobile add-on | Native Android, iOS, React Native, Flutter; partial Cordova or Ionic |
| Implementation burden | Higher with deep taxonomy, privacy, identity, and integrations | Lower for basics; identity, tags, consent, and mobile add work |
| Data export | Plan-dependent Contract and package determine available export workflows | Limited Short lookback and published API quotas constrain broad historical extraction |
| Control | Fullstory | Microsoft Clarity |
|---|---|---|
| Default content handling | Native Private by Default blocks text unless permitted | Native Three masking modes; inputs and dropdowns stay masked |
| Element controls | Exclude, mask, and unmask rules plus configurable privacy settings | Masking modes and targeted masking or unmasking configuration |
| Consent | Configurable consent state and capture controls | Valid signal required for full functionality in EEA, UK, Switzerland |
| Roles | Role-based access, with packaging differences | Administrator and Team Member project roles |
| SSO | Plan-dependent Enterprise SAML, JIT, role mapping | Not primary Company Azure AD authentication is unsupported |
| User deletion | Delete an identified user and associated data | Specific-user deletion requires deleting the project |
| Session deletion | Administrators can delete individual sessions | Individual recording deletion is unavailable |
| Residency | US default; EU on request; no documented migration path | Azure storage; standard contractual clauses for EU transfers |
| Replay retention | Free: one year; paid: contract-defined | Thirty days; labeled or favorited recordings: nine months |
| Configuration changes | Review new fields, rules, and allowlists before capture | Masking changes are not retroactive |

Microsoft Clarity reviews
Reviews are self-selected and uncontrolled. Themes summarize recurring language, not measured prevalence.
| Theme | Fullstory | Microsoft Clarity |
|---|---|---|
| Fast value | Follows capture and workflow setup | Easy setup and immediate visual evidence |
| Depth | Replay, filters, behavioral and technical context | Strong visuals; narrower reporting |
| Friction | Learning, configuration, limits, data complexity | Filtering and recording issues |
| Value | Depends on decision value versus total cost | Free access is a central theme |
Detailed pricing and contract cautions
Compare equivalent volume, recording availability, retention, seats, environments, mobile, AI, export, support, residency, and termination rights. Confirm session definitions and separate replay from analytics retention.
FullstoryFree has different data-rights language from paid terms. Review the current agreement.
Which should you choose?
Match the owner’s recurring question, then test it with real privacy rules and traffic. Public sites, authenticated products, and regulated portals can reach different answers.
| Scenario | Best starting point | Why | Watch-out |
|---|---|---|---|
| Small public website | Microsoft Clarity | Free recordings, heatmaps, filters, funnels | Consent, masking, availability, retention |
| Product designer | Depends | Clarity for light work; Fullstory for a reusable analysis system | Frequency, collaboration, taxonomy, budget |
| UX researcher | Fullstory for recurring studies | Deeper selection and comparison | Replay does not explain motivation |
| B2B SaaS product | Fullstory | Identity, properties, segments, journeys, technical context | Account model, privacy, contract |
| Customer support | Fullstory | User-to-replay investigation with technical evidence | Help-desk integration and access |
| Enterprise access controls | Fullstory | RBAC, Enterprise SAML, settings history | Entitlements, residency, retention |
| Mobile team | Test both | Free Clarity pilot or deeper paid Fullstory analysis | Framework, fidelity, masking, overhead |
| B2B customer success | Neither alone | Both need account adoption and lifecycle context | Connect company, user, visit evidence |
The public site and the authenticated product are different problems
Public and content-led surfaces
Leans Microsoft Clarity
B2B account context — a bridge, not a side
Belongs to neither vendor by default. It has to be instrumented at event time.
Authenticated product
Leans Fullstory
Many teams run both: free coverage on the public site, an investigation platform inside the product. The account layer is what neither gives you for free.
Can the free product replace the paid one?
Clarity can replace Fullstory when replay, heatmaps, simple funnels, filters, and identity cover recurring decisions. A shared replay feature does not replace Fullstory’s analytical, technical, governance, retention, collaboration, or export depth.
| Question | Clarity may be enough when | Keep or choose Fullstory when | Test |
|---|---|---|---|
| Analysis | Filters and funnels isolate the pattern | Sequences, journeys, retention, metrics, richer cohorts matter | Recreate weekly questions |
| Technical evidence | Visual behavior is sufficient | Console, exception, network, or performance changes action | Diagnose a failure |
| Retention | Thirty days fits the cycle | Longer replay or analytics history is required | Audit historical cases |
| Governance | Two roles and masking suffice | SSO, deletion, residency, or auditability matters | Run security review |
| Collaboration | Links, labels, favorites, segments suffice | Workspaces, alerts, notes, or cross-team workflows matter | Observe a handoff |
| Economics | Marginal insight does not justify payment | Faster decisions exceed total cost | Estimate value per case |
Where Hymetry fits
Hymetry fits before replay when a B2B team must choose which company, user, product area, or visit to investigate. It links account adoption to users and Visits, complementing both products.
Visual behavior
Microsoft Clarity starts with website or app behavior
Recordings, heatmaps, filters, Smart Events, and funnels provide free page and screen evidence.
User explanation
Fullstory starts with advanced experience analysis
Segments, funnels, journeys, replay, and technical context support recurring cross-team investigation.
Account context
Hymetry starts with an account or product-area signal
Pages, product areas, and grouped pages connect adoption and user distribution to Companies, Users, and selected Visits.
Explore Companies, Users, Pages, and Visits, or read the guide to product usage by company.
FAQ, methodology, and sources
This comparison is a dated fit analysis based on documented capabilities and public customer feedback, not a controlled benchmark.
Is Fullstory better than Microsoft Clarity?
Fullstory is better for deep behavioral investigation, authenticated products, technical context, and enterprise governance. Clarity is better for fast, free replay and heatmaps.
Is Microsoft Clarity really free?
Microsoft describes Clarity as free forever, without traffic limits or a forced upgrade. Implementation, privacy, governance, analysis, and connected services still cost. Recheck current terms.
Can Microsoft Clarity replace Fullstory?
Yes when recordings, heatmaps, funnels, filters, tags, and identity are enough. No when advanced cohorts, journeys, technical evidence, longer replay, SSO, deletion, or deeper collaboration matter.
Which has better product analytics?
Fullstory’s segments, funnels, metrics, Page Flow, Journeys, retention, dashboards, and replay go beyond Clarity’s filters, funnels, dashboard, and visual evidence. Availability depends on package.
Which is better for a public website?
Clarity is the default starting point for many public sites because it is free and visual. Fullstory can win when value, segmentation, governance, or technical complexity justifies it.
Which is better for an authenticated SaaS product?
Fullstory is stronger for sequences, known-user properties, cohorts, journeys, technical evidence, and durable workflows. Clarity suits smaller teams with simpler questions.
Where does Hymetry fit?
Hymetry connects B2B account and product-area signals to Companies, Users, and Visits. It selects where to investigate; these vendors supply session evidence.
