Where each one falls short

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

Firefly III

  • There is no official managed hosting, so a non-technical user has no easy on-ramp the way Actual Budget offers with its paid hosted sync.
  • The double-entry-influenced model is less intuitive for newcomers than simple envelope budgeting, and the learning curve is real.
  • Automatic bank sync depends on the community-run importer and third-party connectors, and coverage and reliability vary a lot by bank and country.
  • Mobile access is via a web interface rather than a polished native app, which is a step behind Actual Budget or Lunch Money on phones.
  • Because there is no company behind it, security patching and feature development depend entirely on volunteer maintainer time.

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.

Answered from the vendors’ own pages

Firefly III: Can I pay someone to host Firefly III for me?

Not through the core project; some third-party providers sell Firefly III hosting independently, but there is no official managed service.

No, that is the point of the product. Excel is the interface, backed by a central database and workflow.

Firefly III: Does it support multiple currencies?

Yes, natively, including accounts and transactions in different currencies.

Vena Solutions: Is pricing published?

No. Vena quotes per organisation based on users, modules and services.

Firefly III: Is it really free with no paid tier?

Yes, the software is free and open source under the AGPL; the project accepts donations but sells nothing.

Vena Solutions: How much is implementation?

It is quoted separately and commonly forms a large share of first-year cost. Get it itemised before comparing against Anaplan or Adaptive.

Vena Solutions: Does it work without Microsoft Office?

Not properly. The Excel add-in is the main working surface.
