Implementations
KERIpy
KERIpy is the most mature and widely used KERI implementation, written in Python. It serves as a reference for many other implementations in the ecosystem.
Key Features:
- Support for the core KERI protocol specification
- Comprehensive test suite and regular updates from the KERI community
- Example scripts and tooling to help you bootstrap a KERI environment
Use Cases:
- Ideal for anyone wanting a stable, well-documented Python library from which to learn KERI and implement their own applications.
KERIA
KERIA (Key Event Receipt Infrastructure Agent) provides cloud-based agents built on top of the KERI protocol for the purpose of managing KERI identifiers in a hosted environment.
Key Features:
- Preconfigured endpoints for managing KERI events in the cloud
- Integration with KERIpy for event processing
Use Cases:
- Organizations or individuals looking to host their own KERI agent or agent based service
Signify-TS
Signify-TS is a KERI implementation in TypeScript, targeting Node.js and browser-based applications. It is an excellent choice if your stack is JavaScript/TypeScript-heavy.
Key Features:
- Written for modern JavaScript/TypeScript environments; integrate in full-stack or front-end apps.
- Active development to remain aligned with the evolving KERI standard.
- Can be used alongside popular frameworks (React, Angular, Vue) for decentralized identity features.
Use Cases:
- Building user-facing web applications that interact with KERI-based identifiers directly in the browser.
- Developers preferring TypeScript’s type-safety and ecosystem.
