  • Only Lago has a free tier, so it costs nothing to try first.
  • Each has a real cost: Lago free tier limited to 10,000 entities per month with 5M event cap; Vena Solutions vena publishes no pricing and contracts are modular, so two organisations of similar size can pay very different amounts and neither can benchmark without going through procurement.
  • They diverge on capability: Lago covers Real-time usage metering, Vena Solutions covers Excel add-in interface.
  • 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.

Lago

  • Free tier limited to 10,000 entities per month with 5M event cap
  • No specific pricing published for Pro annual plan or Scale plan
  • Self-hosted and on-premise deployments require engineering resources
  • Community support only on free tier
  • Scale plan requires annual contracts and sales engagement

Vena Solutions

  • Vena publishes no pricing and contracts are modular, so two organisations of similar size can pay very different amounts and neither can benchmark without going through procurement.
  • Implementation services for data integration and template configuration typically make up a large part of first-year cost, often exceeding the licence, and that figure only appears in the proposal.
  • Excel dependency is structural: organisations on Google Workspace, or staff working only in a browser or on Chromebooks, cannot use the primary interface as intended.
  • Because it accepts existing spreadsheets, it can preserve years of undocumented logic and circular workarounds rather than forcing the clean-up that a rebuild on a purpose-built modelling tool would require.
  • Model performance degrades with very large dimensional models, so organisations that grow into genuinely large planning problems eventually hit the limits of the spreadsheet-first design and face a second migration.
