What it really isRabbitSign — permanently free unlimited e-signature platform with optional paid automation add-ons.
Our takeRabbitSign is genuinely free for all standard e-signature use: unlimited requests, templates, multi-signer workflows, custom branding, and HIPAA-compliant signing are all included at no cost.
There is no trial; core features are free forever, with an explicit grandfathering promise. Paid usage only kicks in for bulk batch sends beyond 20 docs ($0.025/doc) and API automation. SOC 2 Type II and ISO 27001:2022 certifications make it surprisingly enterprise-grade for a free tool.
Why we rate itNear-zero cost for a fully compliant, unlimited e-signature workflow is almost unheard of.
Serverless architecture keeps RabbitSign's operational costs low enough to sustain the free model, and the grandfathering promise reduces lock-in anxiety.
The catchAutomation (bulk/batch sending and API) requires payment; the free model is manual-only.
Feature depth and native integrations lag behind DocuSign or PandaDoc for complex enterprise workflows.
