Read comparisonBefore you shortlist
Compare the operating model before the feature checklist
A self-hosted signing platform can improve infrastructure and data control, but it also transfers availability, security, backup, and upgrade work to your team. Validate that tradeoff first.
- Deployment ownership
- Decide whether your team wants a managed service or will own runtime security, upgrades, backups, monitoring, and recovery.
- Data and storage
- Map where source documents, previews, attachments, completed PDFs, audit records, and identity evidence must live.
- Integration surface
- Compare the exact APIs, webhooks, embed events, mobile support, authentication model, and rate limits your product uses.
- Evidence requirements
- Test audit exports, PDF signatures, certificate chains, timestamps, validation data, and long-term retention against policy.
