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.
