Signadot
Signadot provides Kubernetes-based sandboxes and validation tools for testing code changes against real services and dependencies.
What Signadot is
Signadot provides Kubernetes-based sandboxes and validation tools for testing code changes against real services and dependencies. Its sandboxes combine changed workloads with a baseline environment, giving teams an isolated way to validate changes across a microservices stack. A CLI and MCP server connect local workstations to Kubernetes clusters, so developers and coding agents can test local changes against real dependencies. Signadot Jobs can run Playwright, Cypress, or custom test suites inside Kubernetes and route them to a sandbox. Platform teams can define actions in validation plans, which developers can assemble into deterministic flows for coding agents. The Starter plan 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 per month; yearly subscriptions receive a 10% discount. Sandboxes are billed per creation, while a complete suite run counts as one test invocation. The operator runs in the customer's Kubernetes cluster, while the Dashboard and API run in AWS.
Good
- Free Starter plan includes 50 sandboxes monthly.
- Tests can run against real service dependencies.
- Supports Playwright, Cypress, or custom test suites.
- MCP integrations include Claude Code and OpenAI Codex.
- Operator runs in the customer's Kubernetes cluster.
Watch out
- Starter allows 100 test invocations per month.
- Business costs $250 a month.
- Business SSO is a $250/month add-on.
- Enterprise pricing is custom and not listed.
Who it suits
Signadot suits developers and coding agents that need to validate changes against real services, as well as platform teams building repeatable validation flows. Starter is described as ideal for individual developers; Business is aimed at small development teams.
Verdict
Signadot centers on isolated Kubernetes testing that uses real dependencies, with local development connections and automated suite runs. The free Starter plan provides a defined monthly sandbox and test allowance; larger team needs may call for Business or custom Enterprise terms.
