Cycloid is an internal developer portal and platform that platform teams customise instead of building from scratch. Branding, sidebar navigation, team and persona pages, resource tabs and concept names all adapt to the organisation. Platform teams set the guardrails once, with SSO, four-layer authorisation, predefined environment types, naming rules, approvals and one audit log. Published Blueprints on Terraform, OpenTofu, Ansible and Helm become golden paths, and developers can also compose their own environments inside the same rules. Developers deploy, run day-2 actions and promote infrastructure and application changes between environments from one portal. The software catalog tracks ownership, relations and DORA metrics, and scorecards rate services. Plugins connect GitHub, GitLab and the major clouds, and jobs run on the Native Runner or existing CI. AI assistants work inside the same checks. Deployment options are SaaS, self-hosted or air-gapped.

Massdriver is an internal developer platform and platform orchestrator. Platform teams publish the Terraform, OpenTofu, and Helm they already write to a catalog; developers and AI agents provision from it with policy enforced before every deploy. Self-hosted or managed. Platform and operations teams encode their security, compliance, and cost requirements into pre-approved modules using the IaC tools they already use. Developers and AI agents discover and provision those modules from a central catalog, and policy is checked before anything is created. Built-in secrets management, monitoring, and attribute-based access control cover AWS, Azure, GCP, and Kubernetes. Massdriver generates an ephemeral pipeline per deploy from each module's own tooling, so there are no standing CI/CD pipelines to maintain. Run it self-hosted, on-prem, or in your cloud, or let Massdriver manage it for you.

configure8 is an internal developer portal that helps helps your developers move faster and build better software with self-serve access to the knowledge and functionality they need. Our solution features a universal catalog that easily organizes all of the sociotechnical knowledge about your team and applications, services, environments, and resources. Customize the data model to integrate any tool and present custom views and calculations. Easy to set-up and maintain, and delivers value. configure8 uses knowledge in the universal catalog to power Scorecards and Self-Serve Actions. Scorecards by configure8 feature the largest library of pre-built checks and the ability to scorecard any custom data as well as create standards tripwires. Self-Serve Actions feature dynamic forms that are contextually aware to minimize developer cognitive load for day 2 operations. We even offer starter templates + custom actions. Deploy on-prem or use our SaaS hosted version. White glove support
