In their own words
Flux CD
Flux CD is a free, open-source set of continuous and progressive delivery tools for Kubernetes. It uses GitOps to reconcile clusters with configuration from sources such as Git repositories, and manages Kubernetes resources along with infrastructure and workload dependencies. Integrations include GitHub, GitLab, Bitbucket, S3-compatible buckets, OCI, container registries, Helm, and Kustomize. With Flagger, it supports canary deployments, feature flags, and A/B rollouts; it can also scan container images and push automated updates back to Git. Flux can send alerts to external systems, including chat systems such as Slack. For multi-tenancy, it uses Kubernetes RBAC through impersonation and supports multiple repositories and clusters. Its CLI and controller images are signed, and controller deployments follow the Kubernetes restricted pod security standard. Flux does not provide its own UI, although third-party interfaces are available. Installation requires cluster-admin rights, and older end-of-life Kubernetes versions are unsupported; the listed minimum versions begin at v1.34.1 for v1.34.
Nullstone
Nullstone is a developer platform for launching and managing applications on cloud providers such as AWS. It can run workloads as containers, serverless apps, static sites, or applications on servers. Preview environments can be created from a pull request or branch and removed after review or testing. Teams provision infrastructure with Terraform modules they can fork, customize, or create from scratch. Nullstone launches infrastructure in customers’ cloud accounts and says it does not access their data; secrets remain in that account in a vault such as AWS Secrets Manager. Its security information lists SOC 2 Type II certification and role-based access controls. Listed integrations include Datadog, NewRelic, SumoLogic, CircleCI, Jenkins, and GitHub Actions. The open-source CLI supports deployments, infrastructure provisioning, data retrieval, and module management on macOS, Windows, and Linux. The Individual plan is free at free; Startup costs $50 a month and includes two users, two environments, and 30 deploys per week. The SaaS service is hosted only and cannot be independently run or installed by customers.
