Cycloid is an Internal Developer Portal and Platform that addresses challenges in self-service and platform orchestration, project lifecycle and resource management, FinOps and GreenOps, and resource optimization through modules and API-first and language-agnostic plugins. With a full GitOps approach, Cycloid allows DevOps and platform teams to save pre-configured automation parameters in a service catalog, to be reused in the self-service portal, designed to modernize existing infrastructure and automate internal processes while ensuring governance and efficient use of resources. Cycloid provides fine-grained security guardrails via RBAC for the end users and platform teams, as well as ways to monitor cloud consumption and cloud carbon footprint. The platform is available as SaaS, dedicated SaaS, or self-hosted on premises, and is accessible via console, command-line interface, Terraform provider or API.
