mirrod offers local debugging. Signadot goes beyond that to support your entire development workflow.

Use cases and capabilities

Signadot

Complete Testing Solution

Platform Focus: Microservices Testing

Creates lightweight, environment isolation using request routing and context propagation.

Comprehensive Scope: Full Shift-Left

Supports local dev, PR testing, and automated integration tests within a unified platform.

CI/CD Integration: Continuous PR Testing

Feasible and affordable for running full tests as a CI step for every PR.

mirrord

Single-Process Local Debugging Tool

Platform Focus: Local Debugging

Injects remote context via syscall interception; lacks application isolation.

Limited Scope: Local Development Only

Exclusively for testing local code in the remote cluster context.

Impractical for CI/CD. Requires a single running local process.

Signadot offers a more comprehensive solution that supports local development, PR previews, and automated testing through lightweight “sandboxes” that provide isolated environments without duplicating infrastructure.

Go far beyond Local Development

Enable on-demand previews and automated tests for every Pull Request. Test features across multiple PRs.

Database and Message Queues

Out of the box support for database isolation and multi-tenancy for Message Queues like Kafka, SQS and others.

Extensible and Scalable

Leverage resource plugins to spin up arbitrary resources on-demand. Scales to 1000s of developers.

Testimonials

Hear From Our Clients

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

With Neon's rapid growth, maintaining key DORA metrics and production SLO became a challenge. Signadot's Sandboxes solution transformed our CI/CD pipelines, reducing costs and enabling effective testing. Now, we can confidently make risky changes, fostering a culture of performance-oriented engineering.

Venkat Karun

Distinguished Engineer and Sócio

I want staging to be in a state where I'm able to push to production any day I want. The quality should be as good as prod so that I don't have to do more work after merging. This is exactly what Signadot allows us to do today. We're now running tests before merging, which means cleaner code and fewer rollbacks.

Buchi Reddy

CEO

Our vision when we started talking to Signadot was that we wanted to have the same stack for testing and production. Signadot has allowed us to do just that, bringing down the lead time for our developers to test changes from 30 minutes to literally 60 seconds.

Integrate with CI tools you already use

Support all test frameworks

Without Signadot, developers were experiencing frequent rollbacks of code due to issues discovered late in the staging environment. Now, the developers have much more confidence in what they are deploying, resulting in fewer breaks on production.

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.

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.
