Trusted by engineering teams worldwide

vCluster creates virtual clusters for isolation. Signadot provides testing sandboxes without the overhead.

vCluster creates virtual Kubernetes clusters within a physical host cluster, providing full isolation with dedicated control planes.

Use cases and capabilities

Signadot

Kubernetes-Native Validation Platform

Virtualized Environments

Lightweight sandboxes isolate changes within your existing cluster. No duplication needed.

Composable Validation

A framework of reusable tools and actions for validating changes against real dependencies at scale.

Agentic Development

Agents and developers validate in parallel. Hundreds of concurrent sandboxes on a single cluster without conflicts.

vCluster

Virtual Cluster Focus

Virtual Cluster Isolation

Full control plane isolation with separate API servers per virtual cluster.

Not designed for application-level testing or PR preview workflows

Signadot combines virtualized environments with a composable validation framework on your existing Kubernetes cluster. Agents and developers get fast, isolated, full-fidelity feedback on every change without linear growth in infrastructure cost.

Previews for Every Pull Request

From web to mobile frontends, generate on-demand previews that let your team test earlier and deploy with confidence.

Launch Previews in Seconds

Don't waste time waiting. Signadot delivers previews in seconds while competitors take minutes, keeping your engineering velocity high.

Cut Infrastructure Cost by 90%

Testing across pull requests without duplicating environments cuts down cloud costs dramatically.

Testimonials

$2M saved annually

On the margin, with the Signadot approach, 99.8% of the isolated environment's infrastructure costs look wasteful. That percentage looks like an exaggeration, but it's really not.

Connor Braa

Software Engineering Manager

83% lower change failure rate

We basically stopped creating full preview environments and replaced our custom solution with Signadot. Instead of isolating the full environment, the strategy using routing keys is much lighter, and we are able to provide an isolated environment, even with isolated databases, per PR quite fast.

Marcus Tavares

Staff Software Engineer

No more fighting over staging

Creating a sandbox is extremely fast, it works every time, lets me test what I'm building quickly, and move on. This is awesome.

Tyler Marien

Senior Software Developer

10x integration capacity

Our engineers were spending more time waiting for an environment than shipping. Now they test against our real services in parallel, which made a whole tier of fixed test infrastructure unnecessary. Retiring environments we had carried for years is projected to save us several million dollars annually.

Feature

Signadot

vCluster

Primary Purpose

Microservices testing with request-level isolation

Fully isolated virtual Kubernetes clusters

PR Previews

Automatically create previews for PR testing

Not designed for this use case

Automated Testing

Built-in support for automated testing (including AI-powered SmartTests)

Out of scope

Isolation Level

Application layer with intelligent request routing

K8s namespace level with separate control planes

Resource Usage

Very lightweight, minimal overhead

Lighter than physical clusters but heavier than sharing

Team Collaboration

Developers and agents can collaborate by combining Sandboxes

Primarily designed for cluster-level isolation

Data Isolation

Supports tunable data isolation strategies

Full data isolation per virtual cluster

Agentic Development

MCP server for autonomous agent workflows

Not designed for agent-driven development

The bottleneck has shifted from writing code to proving it works.

Agentic development only delivers value when code generation velocity converts into shipped product. Signadot provides the validation infrastructure to make that conversion happen: virtualized environments that spin up in seconds and a composable validation framework that makes feedback fast, isolated, and reproducible at enterprise scale.

Integrate with CI tools you already use

Support all test frameworks

Signadot is making it easier for our developers to build and test microservices using deployments that are incredibly similar to production. This has made both human and AI-written code easier to validate and test.

How is Signadot different from other testing solutions?

Unlike traditional approaches that create full duplicate environments, Signadot uses a unique request-routing approach that allows you to test changes in isolation while sharing existing infrastructure. This results in up to 90% cost savings while delivering significantly faster feedback cycles.

How does Signadot integrate with my CI/CD pipeline?

Signadot provides a CLI and API that integrates with all popular CI/CD systems including GitHub Actions, Jenkins, CircleCI, and GitLab. Our integration creates sandboxes for each pull request, runs tests, and reports results back to your pull request, providing complete visibility into test outcomes.

What testing frameworks does Signadot support?

Signadot works with any testing framework you currently use, including Cypress, Selenium, Playwright, Postman, RestAssured, JUnit, pytest, and more. There's no need to rewrite your tests - just point them at your sandbox environments using our routing mechanisms.

Do I need to modify my applications to use Signadot?

No code changes are required to your applications. Signadot works at the network layer by intercepting requests and routing them to the appropriate services. We provide tools like our Chrome extension, SDK, and CLI to make it easy to manage routing without modifying your application code.

How long does it take to set up Signadot?

Most teams are up and running with Signadot in less than a day. Installation involves deploying our Kubernetes operator to your cluster and configuring your CI/CD pipeline to create sandboxes. Our team provides hands-on support to ensure a smooth onboarding experience.

Does Signadot support coding agents?

Yes. Signadot's MCP server lets coding agents (including Cursor, Claude Code, and VSCode) provision sandboxes, run tests, and verify changes autonomously. This turns agents from code generators into autonomous engineers that can validate their own work in a closed feedback loop.

Can Signadot work with our service mesh?

Yes, Signadot integrates with popular service meshes like Istio, Linkerd, and Consul. We can leverage your existing service mesh for routing or use our built-in routing mechanisms if you don't have a service mesh. Our approach is designed to be flexible and work with your existing infrastructure.

Validate code as fast as agents write it. Cut environment costs by 90%.

Explore how Signadot helps engineering teams validate code at the speed agents generate it, with cost-efficient parallel validation on your existing Kubernetes infrastructure.
