What Signadot is

Signadot provides Kubernetes-based sandboxes and validation tools for checking code changes against real services and dependencies. Its sandboxes combine changed workloads with a baseline environment to isolate testing across a microservices stack. Developers and coding agents can use its MCP server and CLI to connect local workstations to Kubernetes clusters and test local changes against real dependencies. Signadot Jobs run Playwright, Cypress, or custom test suites inside Kubernetes and can route tests to a sandbox. Platform teams can define custom actions in validation plans, which developers can compose into deterministic validation flows for coding agents. Integrations include MCP connections for Claude Code, OpenAI Codex, Cursor, Windsurf, and Zed, along with GitHub Actions, GitLab, Jenkins, Bitbucket, Kubernetes, Istio, Linkerd, OpenTelemetry, Kafka, RabbitMQ, Google Pub/Sub, and Temporal. The Starter plan is free; Business costs $250 a month, with a 10% discount for yearly subscription. Sandboxes are billed per creation, and 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.
