Quick answer
Mouseflow - Mouseflow wins for most builders because its free tier works as a standalone starter plan, while Reactflow’s free plan is only available inside an organization that already has a paid Pro or Business website.
How the free tiers compare
The biggest difference is not feature shape, but access. Mouseflow gives you a true free entry point with no card requirement stated, unlimited users, and enough core behavior analytics to evaluate session replay, heatmaps, funnels, and friction detection on a small site. Its limits are mostly on scale: 500 sessions, one project, one funnel, and one month of retention. Reactflow’s free tier is narrower in practice. It has useful extras like bug tracking and a shared script for analytics plus console logs, but it is constrained by 2k daily pageviews, 300 recordings, 30 days of storage, and only 3 heatmaps/funnels/widgets. Most importantly, the free plan is only granted to websites already inside an organization with an active paid plan, so it is less useful as a first-stop builder tool. Reactflow makes more sense as an add-on, not a standalone free tier.
Mouseflow vs Reactflow free tier, side by side
| MouseflowFTV 56 | ReactflowFTV 56 | |
|---|---|---|
| Free traffic limitMouseflow caps sessions per month; Reactflow measures pageviews per day. | 500 monthly sessions | 2k daily pageviews processing |
| Sites / projectsReactflow's free plan is described as available only to websites in an org with a paid plan. | 1 website project | Not stated in the free plan |
| Core analytics limitsReactflow groups heatmaps and funnels under the same count. | 1 conversion funnel | 3 heatmaps and funnels |
| Storage / retentionThese are close in length, but they are described differently. | 1 month of data retention | 30 days recording storage |
| UsersMouseflow explicitly includes unlimited users on free. | Unlimited users | Not stated |
After you outgrow the free tier
Mouseflow uses flat monthly pricing for its first three paid tiers, then contact sales for Enterprise. Reactflow starts at a flat Pro plan, then moves to a tiered Business plan from $69.99/month, with more pageviews and longer storage. For small teams, Mouseflow is cheaper to begin paying at $25/month. Reactflow costs less only if you specifically need its paid-org structure or its higher included pageview/storage limits justify the jump to $69.99/month.

When to pick each one
Pick Mouseflow when…
- You want a free analytics tool for a new site without needing an existing paid org.
- You need unlimited users on the starter plan for a small product, client, or team.
- You are mainly comparing session replay, heatmaps, funnels, and friction detection before paying.
- You only have one website project and low session volume, so 500 sessions/month is enough.
- You want the simplest path from free to paid, with a flat $25/month next step.
Pick Reactflow when…
- You already have a paid Reactflow Pro or Business website and want the included free website tier.
- You care about bug tracking and console-log-style issue visibility in the same script as analytics.
- You want a higher pageview allowance than Mouseflow's 500 sessions, especially for low-friction pageview-heavy sites.
- You need more than one or two core reports on a starter site, but only as an add-on inside an existing org.
- You expect to upgrade into a tiered usage path starting at $69.99/month for more pageviews and storage.
Bottom line
For the most common builder case, Mouseflow is the better free-tier choice because it behaves like a real starter plan you can use on its own. Reactflow’s free offering is more limited in access and is mainly useful if you already have a paid Reactflow organization and want an extra free website attached to it. If you are testing behavior analytics on a new product, Mouseflow is the cleaner starting point.
