Why DocuSeal on Opsily
Enterprise eSignature without the vendor lock-in trap.
eSignature API with no vendor lock-in
PAdES signatures stay valid forever, independently of DocuSeal. Export any document at any time in standard formats. No proprietary lock-in. Your audit logs and metadata are always accessible via the API. Switch tools later without losing a single signature's validity.
Fixed costs, unlimited scale
One price. Unlimited users, documents, and team members. No per-seat surcharges. A 10-person team pays $70-100/month, not $1,200-1,800/year. Larger teams save even more. No surprise billing.
Full API, no gatekeeping
Unrestricted API access on all plans. Webhooks, batch operations, custom audit logs, template management. No rate limits. Enterprise features aren't hidden behind premium tiers. Build the workflows you need, not the ones the vendor allows.

We were paying per user on everything and it added up fast. Now we run five apps for less than one of those old plans. My finance team finally stopped asking questions.

Wanted to use n8n for ages but the self-host part always stopped me. Opsily just handled it. Got the power without becoming an IT person overnight.
