The short version
- Only Actual Budget has a free tier, so it costs nothing to try first.
- Each has a real cost: Actual Budget self-hosting the sync server requires basic comfort with running and updating a small application, which is a real barrier for non-technical users.; Causal causal was acquired by Lucanet on 31 October 2024 and the independent brand has been retired in favour of Lucanet xP&A, so the roadmap, support and pricing you buy are Lucanet’s and not the ones the product built its reputation on.
- They diverge on capability: Actual Budget covers Envelope budgeting, Causal covers Variable-based modelling.
- Prices and features above were last checked on 1 September 2026.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Actual Budget
- Self-hosting the sync server requires basic comfort with running and updating a small application, which is a real barrier for non-technical users.
- Bank sync depends on SimpleFIN or GoCardless connectors rather than a broad built-in aggregator network, so coverage of smaller banks varies by region.
- There is no dedicated customer support line, only community Discord and GitHub issues, which suits technical users but frustrates people expecting vendor support.
- The mobile apps are less mature than the web and desktop experience, and some budgeting workflows are easier on desktop.
- Because it is a smaller open source project, feature development depends on maintainer time and community contribution rather than a funded product roadmap.
Causal
- Causal was acquired by Lucanet on 31 October 2024 and the independent brand has been retired in favour of Lucanet xP&A, so the roadmap, support and pricing you buy are Lucanet’s and not the ones the product built its reputation on.
- Self-serve pricing is gone: the old causal.app pricing page now redirects to a Lucanet solution page, so what was a transparent product you could sign up for is an enterprise sales conversation with no published rate.
- The variable-based model is a genuine departure from spreadsheet thinking, so an accountant fluent in Excel must relearn how to express a model, and the team members who could previously all edit the forecast often cannot at first.
- Deep Excel compatibility is limited by design; complex existing workbooks with macros, circular references or heavy lookups do not import cleanly and have to be rebuilt, which turns a tool evaluation into a modelling project.
- Consolidation, statutory reporting and multi-entity currency handling are weaker than in dedicated corporate performance management suites, so a group with several legal entities usually needs Lucanet’s other modules alongside it, raising the real cost well past the planning tool alone.

Answered from the vendors’ own pages
Actual Budget: Is Actual Budget really free?
The core app and self-hosted sync are free and open source; there is also an optional paid hosted sync subscription if you do not want to run a server.
Causal: Does Causal still exist?
The product does, as Lucanet xP&A. The independent Causal brand and self-serve offering have been retired following the October 2024 acquisition.
Actual Budget: Do I need a server to use it?
Only if you want to sync a budget across multiple devices; a single-device budget works without any server at all.
Causal: What does it cost now?
Nothing is published. The former pricing page redirects to Lucanet, and the product is quoted as part of the Lucanet CFO Solution Platform.
Actual Budget: Does it connect to my bank automatically?
Yes, through SimpleFIN or GoCardless connectors, though coverage is narrower than commercial aggregators used by YNAB or Lunch Money.
Causal: Can I import my existing Excel model?
Simple workbooks import. Models with macros, circular references or heavy lookup chains have to be rebuilt around named variables, which is the real migration cost.
Causal: Is it a replacement for a consolidation tool?
No. It plans and forecasts. Statutory consolidation and multi-entity reporting sit in Lucanet’s other modules.
