In their own words
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.
Signadot
Signadot provides Kubernetes-based sandboxes and validation tools for checking code changes against real services and dependencies. Each lightweight sandbox combines changed workloads with a baseline environment for isolated testing across a microservices stack. A CLI and MCP server connect local workstations to Kubernetes clusters, allowing developers and coding agents to test local changes against those dependencies. Signadot Jobs run Playwright, Cypress, or custom test suites inside Kubernetes and can route tests to a sandbox. Platform teams can define actions in validation plans, which developers can assemble into deterministic validation flows for coding agents. Listed MCP integrations include Claude Code, OpenAI Codex, Cursor, Windsurf, and Zed; other integrations include CI systems, Kubernetes, service meshes, observability, messaging, and workflow tools. Starter is free and includes 50 sandboxes and 100 test invocations per month. Business costs $250 a month and includes 100 sandboxes and 200 test invocations monthly, with a 10% yearly-subscription discount. Sandboxes are billed per creation; a complete test-suite run counts as one invocation. The operator runs in the customer's Kubernetes cluster, while the Dashboard and API run in AWS.
