Inkless

Inkless is the unicorn in e-signature tools: truly unlimited free signatures with zero usage caps or hidden paywalls. Upload PDFs, add signature/initials/date fields, send to unlimited signers—no limits. Every signature is legally binding (ESIGN/UETA compliant), includes audit trails, tamper-proof certificates, and secure AES-256 storage in Inkless Drive. For indie hackers and pre-revenue startups, this is a revelation compared to DocuSign's per-document meters and monthly quotas.\n\nThe free tier includes multi-signer workflows, real-time notifications, SMS reminders, and integrations with Zapier and Slack. Unlike BoldSign (which limits the free tier to 25 requests/month), Inkless imposes no ceiling. For bootstrap-stage founders processing contracts, NDAs, and client agreements, Inkless eliminates one major SaaS subscription entirely. The caveat: Inkless is newer and smaller than DocuSign, but user reviews on G2 highlight reliability and simplicity.
