Can I open-source Firstbase?
NOT REALLY · nothing credible yetNo credible open-source replacement for Firstbase yet — Documenso are the closest escape hatches, but they don't cross the moat. People still pay for Firstbase because the durable value is expert accountability and regulated execution; document generation alone cannot supply either. The recurring cost buys law changes, jurisdiction, template provenance, access, signatures, filings, deadlines, evidence, retention, security, and professional liability, not just the visible interface.
