The short version

  • Each has a real cost: Mouseflow the free plan is 500 sessions a month, one website and one month of data retention; Terra the absence of a licence fee hides the real cost driver: an idle notebook virtual machine left running overnight, or a workspace bucket full of intermediate workflow outputs, quietly consumes grant money with no vendor invoice to prompt a review.
  • They diverge on capability: Mouseflow covers Session Replay, Terra covers No platform licence fee.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Mouseflow

  • The free plan is 500 sessions a month, one website and one month of data retention
  • Data retention is tiered, from 1 month on free to 12 months on Premium at $319 a month
  • Essential at $25 a month covers a single website project
  • SSO, custom privacy settings and priority support are on the higher tiers only
  • The 14 day money-back guarantee applies to annual subscriptions and excludes Enterprise

Terra

  • The absence of a licence fee hides the real cost driver: an idle notebook virtual machine left running overnight, or a workspace bucket full of intermediate workflow outputs, quietly consumes grant money with no vendor invoice to prompt a review.
  • Cost governance is entirely the customer responsibility, and grant-funded groups without a cloud engineer routinely overspend before anyone reads the Google or Azure bill in enough detail to find the cause.
  • It assumes genuine bioinformatics competence: writing or adapting WDL workflows, managing data tables and debugging failed tasks are all on you, so a wet lab without computational staff cannot use it productively.
  • Feature parity between the Google Cloud and Azure deployments is not identical, so a decision on cloud provider constrains which capabilities and datasets you can reach and is expensive to reverse later.
  • It is a research platform rather than a regulated clinical system: it is not a validated GxP environment and does not carry the qualification package a diagnostic or submission workflow would require, so clinical use needs additional infrastructure and validation you provide yourself.

Answered from the vendors’ own pages

Mouseflow: Is there a free version of Mouseflow?

Yes, Mouseflow offers a free plan with up to 500 monthly sessions, 1 website project, and 1-month data retention.

Source
Terra: Is Terra really free?

The platform is. There is no licence fee. Everything you pay is Google Cloud or Azure compute, storage and egress, passed through at cost.

Mouseflow: What is the most popular Mouseflow plan?

The Advanced plan at $109/month is marked as most popular, offering 25,000 monthly sessions and 6 months of data retention.

Source
Terra: What actually drives the bill?

Running virtual machines and stored data. Pausing notebooks drops a virtual machine from about 0.22 to about 0.027 dollars an hour, and deleting intermediate workflow outputs is the other main saving.

Mouseflow: Does Mouseflow offer annual billing discounts?

Yes, Mouseflow offers up to 35% savings when billed annually instead of monthly, and provides a 14-day money-back guarantee.

Source
Terra: Can I use it with protected health information?

Yes. Terra signs HIPAA business associate agreements and GDPR data processing agreements, and the Azure deployment holds FedRAMP Moderate authorisation.

Terra: Is it validated for clinical or GxP use?

No. It is a research platform. Regulated clinical or submission workflows need validation and controls you build yourself.
