Konsolidat is free financial consolidation software in the only sense that matters for open source: the self-hosted edition has no license fee and no per-user charge under MIT. You still pay infrastructure and ops. Hosted starts from $3,500/month. A 4-week pilot starts from $25,000. If you want “free forever SaaS,” that is not this product.

The expensive part of DIY consolidation is not Microsoft 365. It is the person who understands the 80 workbooks, the IC matrix that breaks at month-end, and the audit trail that does not exist. Konsolidat puts that engine in version-controlled SQL, still queried from Excel.
Yes — Konsolidat’s self-hosted edition is free of license (MIT). You still pay infra and ops. Hosted from $3,500/month and the pilot from $25,000 are paid. It is not free SaaS forever.
The software license is free. Running it is not zero-cost. Source: github.com/grynn-in/konsolidat.
