OpenCred

OpenCred is an MIT-licensed toolkit for issuing and verifying W3C Verifiable Credentials through a desktop application or a Docker-based server. It suits individuals and small teams that need local credential work, as well as organizations integrating issuance into their own systems. The main appeal is control over keys and data without a subscription; the main qualification is that some current interoperability needs are not yet covered.

Overview

OpenCred is published by NFH Trust Labs as a Networks for Humanity initiative. Its free OpenCred plan includes the desktop app or a self-hosted Docker server, with digital certificates, digital badges, public verification, custom branding and API access. Because the software is open source under the MIT licence, organizations can operate it on infrastructure they control rather than adopting a hosted credential platform.

This model is particularly appropriate when custody of signing keys and credential data is a requirement. It is less suitable for a buyer who wants a managed service with a vendor handling deployment and operations, or who depends on OID4VCI today.

Key features

The desktop app issues, manages and exports credentials, including PDFs containing scannable QR codes. That is a useful workflow for individuals and small teams producing certificates or badges directly from a computer, without first building an automated backend.

For larger operations, the Docker image supplies a headless HTTP API for automated issuance and verification. The API and CLI can be embedded in existing student-records, HR and billing systems, allowing credential tasks to become part of established business processes. This is the stronger option for organizations issuing at scale, although self-hosting also leaves deployment, maintenance and security operations with the organization.

Supported verification inputs include JSON-LD credentials, vc-jwt, sd-jwt-vc and PixelPass QR data. Credentials issued with did:key can be verified fully offline, which fits environments where connectivity is unreliable or prohibited. did:web credentials require network access to retrieve the issuer's DID document, so they are not equivalent for disconnected verification.

OpenCred keeps issuer signing keys in the issuer's environment: desktop keys remain on the machine and server keys remain in the issuer-operated container. The Docker image runs in the operator's infrastructure and sends no data to OpenCred or NFH Trust Labs. Those properties make the product a strong match for privacy-sensitive deployments, provided the operator can protect its own machines and containers.

OID4VCI support is planned rather than present. Teams whose issuance flow depends on that specification should treat this as a material compatibility gap.

Pricing

OpenCred — free (free under the MIT licence; desktop app or self-hosted Docker server).

There is no free trial because the product is free, and no paid tier or recurring renewal is described. The same zero-price offer covers desktop use and self-hosting, making it attractive to individuals, small teams and organizations that can provide their own infrastructure. The trade-off is that self-hosted users take on operating responsibilities rather than paying for a managed plan.

Platforms

OpenCred supports API, Linux, macOS, self-hosted, web and Windows environments. The desktop route is therefore suited to local work on supported computers, while the Docker server and API target infrastructure-based deployments. Its platform range is broad, but the practical division remains clear: desktop for individual or small-team issuance, and self-hosted server operation for organizational automation.

Who it's for

Choose OpenCred if you are an individual or small team that wants to issue, manage and export credentials locally, or an organization that needs API-driven issuance and verification inside student, HR or billing software. It is also a sensible choice when keeping signing keys and credential data within your own environment is more important than outsourcing operations.

Look elsewhere if you require OID4VCI immediately, prefer a fully managed service, or cannot support the operational work that accompanies a self-hosted Docker deployment.

Pros and cons

Pros

• Free and MIT-licensed: both the desktop app and self-hosted Docker server are included at 0.00 USD, with no paid renewal described.
• Local key custody: signing keys stay on the desktop machine or in the issuer's container, keeping control with the issuer.
• Privacy-oriented deployment: the Docker image runs in the operator's infrastructure and sends no data to OpenCred or NFH Trust Labs.
• Useful integration surface: an HTTP API and CLI can connect credential workflows to student records, HR and billing systems.
• Offline option: did:key credentials support fully offline verification.

Cons

• OID4VCI is not supported yet: organizations depending on that standard must wait or choose another product.
• Self-hosting is a responsibility: server users must operate and secure their own Docker environment.
• did:web needs connectivity: verification cannot be completed offline when the issuer uses did:web.
• Support is community-oriented: bug reports, requests and questions go through GitHub issues, with security vulnerabilities handled through private reporting.

Alternatives

For a broader category comparison, see Credentialing Software.

Awero is a better fit when Android and iOS access or a freemium service with personal and organisation accounts matters more than local-first operation; its Open Access plan is free, while a custom-look platform setup costs 1500.00 EUR once.

CanCred Factory suits teams seeking a freemium, cross-platform service with a free trial and Android, iOS, web and API support.

POK is worth considering for unlimited free Web2 credentials with no user caps, or pay-as-you-go blockchain verification at 0.30 USD once.

Blockcerts is another free, self-hostable option across Android, API, iOS and web; issuing certificates may incur blockchain transaction fees.

Open Badge Passport is a free open-source choice for personal use on Android, iOS and web.

Certifier fits buyers wanting a hosted API and web service with a free Starter plan capped at 250 credentials per year, one user, five templates and three forms.

CertSeal offers a hosted or self-hosted route with a free plan limited to 100 certificates per year, one batch, one organization member and one workspace.

CREDEBL is a free open-source alternative with community support through GitHub, Discord and a forum.

Verdict

OpenCred is a strong recommendation for individuals, small teams and organizations that want free, open-source credential issuance with keys and data kept in their own environment. Its desktop workflow, integration-ready API and offline-capable did:key verification give it practical range. Look elsewhere if you need OID4VCI now or want a vendor-managed service instead of operating the infrastructure yourself.
