Certipha vs POK

Certipha is a certificate issuance and verification platform for publishers, trainers, employers, and other organizations. It handles publication, conference, training, employment, membership, award, internship, and service certificates. Issuers can upload recipient lists in CSV or XLSX format, generate PDFs, and download them together in a ZIP. Ten designer templates, issuer branding, custom prefixes, signatures, and branded QR codes support presentation choices. Anyone can check a certificate by ID or QR code on a public page without an account. Issuers can revoke certificates with a reason, with status updates shown on that page. DOI import retrieves article metadata from CrossRef or Zenodo, while optional email delivery uses the issuer’s Resend setup. A REST API supports tenant-scoped issuance keys, and an embeddable badge displays current status without tracking cookies or external dependencies. Workspaces include admin, editor, and viewer roles.

POK (Proof of Knowledge) helps organizations issue, manage, and verify digital credentials and microcredentials, including Open Badges 3.0 credentials on blockchain. Each credential has a unique link and QR code that opens a public page with the issuer, holder, date, skills, and current status. Its template editor supports logos, backgrounds, typefaces, signatures, custom attributes, dynamic API images, and paper formats. Organizations can issue credentials in bulk from Excel or CSV files; the free plan has no user cap or added bulk-issuance cost. Connections include Moodle, Canvas, Blackboard, D2L Brightspace, and Open edX through LTI 1.3, Sana through xAPI, and other systems through LTI, API keys, REST API, or webhooks. LMS rules can issue credentials after course completion, optionally with a minimum grade. POK supports several credential standards and offers white-label branding. Its Free Web2 plan is free; blockchain verification is $0.30, paid once, or $3,000 a year for up to 50,000 credentials.
