The best fullstory alternatives
#1PostHog
Best for: Engineering led product teams4.5/5 on
G2 (1,053 reviews, checked Oct 2026)
Visit posthog.com
Starting priceFree
Free planYes
PostHog is the best Fullstory alternative for engineering led product teams. It combines session replay, heatmaps, funnels, and product analytics in one platform, with console and network data attached to replays for debugging. Its free tier covers 5,000 recordings per month, and its open source core lets teams self host or inspect the code.
The limits are pricing growth and complexity. Usage based pricing grows with recording volume, the interface assumes technical skill, and free tier support leans on community. For a product team that wants replay plus analytics without enterprise sales calls, PostHog is the first tool to test.
What we like- Replay, heatmaps, and product analytics in one platform
- 5,000 recordings per month free
- Open source core
Watch out for- Usage based pricing grows with volume
- Interface assumes technical skill
- Support is community heavy on free tier
#2LogRocket
Best for: Debugging technical issues4.6/5 on
G2 (2,403 reviews, checked Oct 2026)
Visit logrocket.com
Starting priceSee website
Free planYes
LogRocket suits product and engineering teams debugging technical issues. Its replay pairs with console logs, network requests, and error data, so an engineer can see exactly what code did when a user hit a problem. Its AI Galileo feature summarizes sessions and surfaces likely causes, which speeds triage for support and engineering.
The trade is price clarity. Published starting prices conflict, from $99 per month in some comparisons to $176 per month for 25,000 sessions in others, so the entry price is "See website" here. Session based pricing grows fast with traffic. For a team whose main job is fixing bugs found in replays, LogRocket is the strongest debugging pick.
What we like- Replay paired with console logs, network requests, and errors
- AI Galileo summaries
- Web and mobile support
Watch out for- Pricing sources conflict from $99 to $176 per month
- Session based pricing grows fast
- Enterprise plan is quote only
Starting price$40 per month
Free planYes
Contentsquare, which now includes Hotjar, suits marketers and UX teams that need recordings, surveys, and feedback together. Its free tier covers 200,000 sessions per month, far more than most rivals, and its Growth plan starts near $40 to $49 per month depending on session band. Heatmaps, funnels, and feedback widgets round out a UX research toolkit.
The limits are plan variation and replay caps. Growth pricing varies by session band, enterprise features need higher tiers, and replay allowance is fixed rather than unlimited. For a UX team that wants recordings plus direct user feedback, Contentsquare is the most complete suite.
What we like- Recordings, heatmaps, surveys, and feedback in one suite
- Free tier to 200,000 sessions
- Strong UX research tools
Watch out for- Growth plan pricing varies by session band
- Enterprise features need higher tiers
- Replay allowance is fixed
Starting priceFree
Free planYes
Microsoft Clarity is free forever with unlimited sessions, which makes it the best starting point for any team on a zero budget. It offers session recordings, heatmaps, funnels, and AI summaries with no traffic cap, so a small site can record every session without worrying about metered costs. Setup takes minutes with a simple script.
The limits are depth. Clarity lacks the error tracking depth of LogRocket and the product analytics depth of PostHog or Heap, and it needs a Microsoft account. For a team that wants free replay and heatmaps without limits, Clarity is unbeatable on price.
What we like- Free forever with unlimited sessions
- Heatmaps and funnels included
- AI summaries
- No traffic cap
Watch out for- No error tracking depth
- Fewer product analytics features
- Microsoft account required
#5Smartlook
Best for: Web and mobile product analytics4.6/5 on
G2 (874 reviews, checked Oct 2026)
Visit smartlook.com
Starting price$55 per month
Free planYes
Smartlook covers web and mobile product analytics with session replay, heatmaps, and funnels in one tool. Its free tier records 3,000 sessions per month, and paid plans start at $55 per month, which suits small and mid size product teams that want replay without enterprise complexity.
The trade is ecosystem and scale. Its ecosystem is smaller than PostHog, advanced features need higher tiers, and session limits bind on larger sites. For a small product team that wants web plus mobile replay at a fair price, Smartlook is a practical pick.
What we like- Web and mobile replay
- Heatmaps and funnels
- 3,000 sessions per month free
- Straightforward setup
Watch out for- Smaller ecosystem than PostHog
- Advanced features need higher tiers
- Session limits bind on larger sites
Starting priceFree
Free planYes
OpenReplay suits privacy conscious and self hosted teams that need session replay under their own control. Its open source core is free to self host, with privacy controls, DevTools data, and performance metrics in replays. Teams in regulated industries or strict GDPR environments gain data residency that cloud only tools cannot offer.
The limits are effort and cloud price. Self hosting needs engineering time for setup and maintenance, cloud plans start near $199 per month, and its community is smaller than PostHog. For a team that must own its replay data, OpenReplay is the best privacy first choice.
What we like- Free self hosted edition
- Privacy controls and GDPR focus
- Console, network, and performance data in replays
Watch out for- Self hosting needs engineering time
- Cloud plans start near $199 per month
- Smaller community than PostHog
#7Heap
Best for: Autocapture product analytics4.4/5 on
G2 (1,097 reviews, checked Oct 2026)
Visit heap.io
Starting price$3,600 per year
Free planYes
Heap suits product teams that want autocapture analytics: it records every user action automatically, so analysts can define events retroactively without re-instrumentation. Its free plan covers 10,000 sessions per month, and Heap Illuminate surfaces insights without manual funnel building. Session replay arrives as an add on for teams that need it.
The trade is replay gating and price opacity. Replay sits only on Pro and Premier plans, Growth pricing is estimated after install at about $3,600 per year, and higher tiers are quote only. For a product team that values retroactive analytics above replay depth, Heap is a strong pick.
What we like- Autocapture records everything retroactively
- Free plan to 10,000 sessions
- Heap Illuminate insights
Watch out for- Session replay is an add on on Pro and Premier
- Growth pricing is estimated after install
- Higher tiers are quote only
#8Mouseflow
Best for: Form analytics and friction detection4.6/5 on
G2 (691 reviews, checked Oct 2026)
Visit mouseflow.com
Starting price$25 per month
Free planYes
Mouseflow leads some heatmap and session replay rankings for its form analytics and friction detection. It records sessions, builds funnels and journeys, and flags where users struggle in forms, which suits conversion focused teams. Its free plan records 500 sessions, paid plans start at $25 per month for 5,000 sessions, and every plan includes unlimited users.
The limits are retention and depth. The free tier keeps data only a month, retention stretches to a year only on the third paid tier, and replay depth trails LogRocket. For a team focused on forms and friction, Mouseflow is the most targeted pick.
What we like- Form analytics and friction scoring
- Funnels and journeys
- Free plan with 500 sessions
- Unlimited users on every plan
Watch out for- Free tier keeps data only a month
- Retention stretches only on higher tiers
- Smaller replay depth than LogRocket
How we chose
We ranked tools by replay quality, heatmaps, error integration, privacy controls, and price. We favored tools with free tiers that cover real work, since a team should test replay on real traffic before paying, and we gave extra weight to error integration, because a replay without technical context only shows half the problem. We also weighed capture model: autocapture records everything retroactively but stores it all, event tracking captures what you instrument, and sampled sessions keep costs down but miss data.
We also weighed privacy honestly. Self hosted tools like OpenReplay give data control that cloud tools cannot, while free tools like Clarity trade depth for unlimited coverage. Price figures that conflicted across sources were written as "See website", so readers check the vendor pricing page rather than trusting a stale number.
Buying guide
Start by defining what you need from replay: debugging, UX research, or conversion insight. Debugging teams need console and network data, so LogRocket or PostHog fits. UX teams need heatmaps, surveys, and feedback, so Contentsquare fits. Conversion teams need form analytics and friction scores, so Mouseflow fits. Buying the wrong type wastes more than buying a dearer tool of the right type.
Next, test with real traffic and real privacy rules. Record a week of sessions, check whether sensitive fields are masked, confirm data retention fits your policy, and see whether the team actually watches replays. A tool nobody opens is wasted money at any price.
Finally, watch the meter. Session based pricing grows with traffic, so a tool that costs $25 per month at 5,000 sessions can cost far more at 500,000. Start with a free tier like Clarity or PostHog, measure monthly session volume, then pick a paid plan that covers real volume with headroom.
Frequently asked questions
What is the best free Fullstory alternative?
Microsoft Clarity is the best free alternative, with unlimited sessions, heatmaps, and funnels at no cost. PostHog offers a free tier of 5,000 recordings per month for teams that also need product analytics.
Do session replay tools record passwords?
Reputable tools mask sensitive fields by default, and OpenReplay and LogRocket offer configurable masking. Always verify masking on your own forms before recording production traffic, and check data retention settings.
What is the difference between session replay and heatmaps?
Session replay shows individual user sessions as video-like playback, while heatmaps aggregate clicks, scrolls, and attention across many users. Most teams use both: heatmaps find problem areas, replays show why they happen.
Is session replay legal under GDPR?
Session replay can comply with GDPR when it masks personal data, obtains proper consent where required, and stores data under appropriate controls. Self hosted tools like OpenReplay give the most control over data residency.
Can session replay replace product analytics?
No. Replay shows individual behavior, while product analytics shows trends across users, funnels, and cohorts. Tools like PostHog and Heap combine both, which is why they suit product teams better than replay only tools.
