Questions
- What is the difference between ActiveCanvas and DocuSeal?
- ActiveCanvas and DocuSeal both sit in content, but they solve different parts of it.
- Can I mount both ActiveCanvas and DocuSeal in the same Rails app?
- Technically yes — engines mount at different paths — but they overlap, so running both usually means two sets of tables doing one job. Pick one.
