Upbound

Upbound provides a platform for engineering teams to build and manage cloud-native control planes using Crossplane. It enables the composition of cloud resources into self-service APIs, streamlining infrastructure management and developer workflows. The platform focuses on automation, security, and scalability for internal developer platforms and cloud infrastructure.

Upbound is a platform for building and managing cloud-native control planes using Crossplane. While it doesn't offer a drag-and-drop UI builder in the same vein as Retool for general internal tools, it provides tools for composing cloud resources and exposing them as self-service APIs, which aligns with the concept of building internal applications. It explicitly mentions API and database integrations (through Crossplane providers), code customization (building compositions), access control and security (IAM, RBAC, SSO), flexible deployments (managed service, self-managed, hybrid), debugging tools (simulating changes, observability pipeline), version control integration (GitOps), audit logs and analytics, and workflow automation (automating lifecycle of resources). It also mentions building 'Portals and Interfaces' and 'Partner & Customer Portals', which aligns with the 'Partner & Customer Portals' feature.
