About Signadot
What is Signadot?
Signadot is a scalable agentic development platform that gives developers and AI coding agents the fastest path from code to merge. It creates lightweight, ephemeral sandboxes on your existing Kubernetes cluster, allowing you to validate every code change against real dependencies—no mocks, no duplicated infra.
Who is it for?
Signadot is built for engineering teams—especially those using AI coding agents—who need fast, isolated environments to test changes pre-merge. It is ideal for teams on Kubernetes who want to cut infrastructure costs (one customer saved $2M annually) and catch bugs earlier. It is less suited for non-Kubernetes setups or teams without a CI/testing culture.
Key Use Cases
Teams use Signadot for pull request previews, running E2E and integration tests massively parallel, and providing instant feedback to coding agents in the inner development loop. It integrates with Playwright, Cypress, and custom test suites, and its Plans feature encodes validation logic as reusable workflows for agents.
Key features
- Sandboxes (Ephemeral Environments) — Lightweight, isolated environments that share your existing cluster. Spin up in seconds, scale to 100s in parallel, with zero duplication of infrastructure.
- Jobs (Scalable Test Execution) — Run Playwright, Cypress, or custom test suites massively parallel inside your cluster, auto-routed to sandboxes.
- Plans (Validation Logic) — Compose actions (HTTP requests, test runs, custom scripts) into reusable validation flows that coding agents run autonomously.
- Inner Loop for Agents — Local MCP/CLI integration so agents get instant feedback, debug failures, and iterate without human handoff.
- Outer Loop for PRs — Automated sandbox creation and comprehensive validation (regression, E2E, non-functional) for every pull request.
- Kubernetes-Native — Runs inside your existing K8s cluster; supports multi-cluster RouteGroups on Enterprise.
- Resource Plugins — Extend sandbox resources (databases, caches, etc.) via plugins; 5 included in Business plan, unlimited in Enterprise.

Frequently asked questions
Is Signadot free?
Yes. Signadot offers a free Starter plan with 50 sandboxes/month, 100 test invocations, and 10 concurrent devboxes—no credit card required.
How much does Signadot cost?
Starter is free. Business plan costs $250/month (annual discount available). Enterprise is custom-priced. All plans include a 30-day free trial.
What are ephemeral environments in Signadot?
They are lightweight, isolated sandboxes that run on your existing Kubernetes cluster. They spin up in seconds and are used to test code changes against real dependencies without duplicating infrastructure.
Who is Signadot best for?
It is best for engineering teams on Kubernetes—especially those using AI coding agents—who want fast feedback loops, catch bugs pre-merge, and reduce infrastructure costs.
What are the top alternatives to Signadot?
Alternatives include Preview environments from platforms like Vercel or Render, and ephemeral environment tools such as Okteto, Nocalhost, and Loft. Signadot differentiates with its agentic coding workflow and Plans automation.
What is a key limitation of Signadot?
Signadot requires a Kubernetes cluster. Teams not on Kubernetes or without a CI/testing pipeline may find it less applicable.
