Here are good digital-badge platforms commonly used for online courses, with quick notes to help you choose.

Top platforms

• Credly — Enterprise-grade badge issuing, verification, and sharing; strong employer-recognition and analytics for large programs.
• Badgr — Open-badging friendly, good LMS integrations and xAPI/LRS support; often chosen by institutions and for self-hosting/open workflows.
• Accredible — Focuses on both certificates and badges with embeddable/verifiable credentials and reporting tools; good for course platforms and MOOCs.
• Open Badge Factory — Badge design and issuance platform built around the Open Badges standard; often used by education providers and consortia.
• BadgeOS (WordPress plugin) — Add badge issuing and gamification to a WordPress-based course site; good for small orgs or independent instructors.
• Blockcerts (or blockchain-enabled solutions) — For organizations that want tamper-evident/blockchain-backed credentials and long-term verification.

Key features to compare

• Standards & portability: Open Badges (IMS) support ensures recipients can store and share badges across wallets and platforms.
• Integrations: LMS (Moodle, Canvas, Blackboard), LTI, xAPI/SCORM, identity systems, SSO, and API access for automation.
• Issuing workflow: bulk issuing, cohort management, manual review, evidence attachments, expiry/revocation.
• Verification & security: public verification, tamper-proofing (blockchain options), and fraud prevention.
• Analytics & reporting: recipient metrics, employer views, completion tracking.
• Cost & scale: free/basic tiers vs per-badge/seat/enterprise pricing; hosting (cloud vs self-host).
• UX for recipients: easy claiming/sharing (LinkedIn, social, resume), badge wallet support.

Which to pick (short guidance)

• Enterprise / employer-recognized programs: Credly or Accredible.
• Institutions / open standards / LMS integration: Badgr or Open Badge Factory.
• Low-budget / WordPress-based courses: BadgeOS.
• Tamper-evident / long-term verification: Blockcerts or blockchain-enabled vendors.

Implementation tips (quick)

• Model each badge to align with a clear learning outcome and published criteria.
• Attach evidence (projects, rubrics, assessment results) to badges so employers can verify skills.
• Use Open Badges v2 and LTI/xAPI for portability and analytics.
• Plan issuance rules (automatic vs manual), expiration/revocation policy, and how badges map to transcripts or micro-credentials.

If you want, I can:

• build a one-page comparison table (features, integrations, price range) for any subset of these platforms, or
• recommend the best match given your LMS, scale, and budget — tell me those and I’ll pick the top 2–3 options.
