Certimate is a self-hosted SSL certificate management tool that automates the full lifecycle of certificate issuance, deployment, renewal, and monitoring through a visual interface.
The tool solves the complexity of managing SSL certificates across multiple domains and infrastructure by orchestrating the entire workflow automatically. It uses ACME protocol integration to request certificates from multiple certificate authorities, handles DNS-01 and HTTP-01 challenge methods, and supports various certificate formats including PEM, PFX, and JKS. The approach combines certificate acquisition with deployment automation, allowing users to configure workflows that apply certificates directly to their infrastructure without manual intervention.
Certimate suits teams managing certificates across diverse infrastructure who want to eliminate manual renewal processes and centralize certificate lifecycle management. It is particularly valuable for organizations using multiple cloud providers or deployment targets, as it supports over seventy domain registrars and more than one hundred sixty deployment destinations including Kubernetes, CDNs, WAFs, and load balancers. The tool's self-hosted nature means all certificate data and operations remain private and local, with no external dependencies on databases or runtimes. Its minimal resource footprint and cross-platform compatibility make it accessible for small deployments through large infrastructure operations. The README does not compare Certimate to alternative tools.
The project maintains active development with regular updates to its provider integrations and features. The codebase is written in Go and designed for immediate deployment without external dependencies. The tool includes a web interface for visual workflow configuration and supports multiple notification channels for certificate lifecycle events.
