The short version

  • Only Mouseflow has a free tier, so it costs nothing to try first.
  • Each has a real cost: Chemaxon the October 2024 Certara acquisition ended two decades of vendor neutrality, and organisations that embedded JChem precisely because Chemaxon competed with nobody now depend on a component owned by a company that sells into their accounts.; Mouseflow the free plan is 500 sessions a month, one website and one month of data retention
  • They diverge on capability: Chemaxon covers Marvin, Mouseflow covers Session Replay.
  • 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.

Chemaxon

  • The October 2024 Certara acquisition ended two decades of vendor neutrality, and organisations that embedded JChem precisely because Chemaxon competed with nobody now depend on a component owned by a company that sells into their accounts.
  • Licensing is genuinely complicated, with different terms for named users, servers, desktop applications and embedded redistribution, so working out what you are allowed to deploy usually requires a conversation rather than reading a document.
  • The free academic package is granted for two-year terms and covers education rather than research, so a research group that assumed it was free discovers it needs a paid commercial academic licence.
  • Nothing is priced publicly for commercial use, so a team evaluating Chemaxon against open source alternatives such as RDKit cannot compare total cost without entering a sales process.
  • Open source cheminformatics has closed much of the functional gap for basic structure handling and search, so the commercial case increasingly rests on prediction quality, support and registration workflows rather than on capability that cannot be obtained elsewhere.

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
