Signadot vs Telepresence
Telepresence tunnels traffic between your laptop and a remote cluster. Signadot gives local development, PRs and coding agents one model: ephemeral environments that copy only what changed and share the rest.
Trusted by engineering teams worldwide
Both let you test against real services instead of mocks, but they work at different levels. Telepresence works at the network level and has no concept of an environment. Signadot is built on the ephemeral environment, one model for local development, PRs, tests and agents, whether a person or a coding agent writes the code. For the wider field, see our Telepresence alternatives guide.
| Feature | Signadot | Telepresence |
|---|---|---|
| Foundation | One model, the ephemeral environment, for local dev, PRs and coding agents. | A network tunnel. Every laptop needs cluster access. |
| Coding agents | Agents on laptops or in the cloud each get an ephemeral environment for Jobs and Plans. | An MCP server drives the tunnel from a desktop. Nothing for cloud agents or tests. |
| PR environments | The core of the product. Hundreds share one cluster. | None. |
| Databases, queues and more | Any database or queue. Resource plugins add anything else. | None. Every laptop uses the same shared data. |
| Service mesh and Gateway API | Native on Istio, with no extra sidecar. Gateway API and Linkerd too. | Adds its own agent beside the mesh sidecar. No mesh routing. |
| Testing: Jobs and Plans | Jobs run your tests. Plans let agents build test workflows. | None. You run tests on your own. |
| Commercial support | Sold and supported by Signadot. | None. A community project, kept up mostly by one maintainer. |
A fit when a free network tunnel is all you need.
The choice when local dev, PRs and coding agents should share one model.
Agents write code faster than teams can check it. Signadot gives every change its own environment with real services and data, so your tests and agents can show it works.
The Signadot platform
Signadot spins up an ephemeral environment for every code change, from a developer's laptop to thousands of coding agents, so your tests and agents can check it against your real services, databases and message queues.
Built for Agents
Each agent gets its own lightweight ephemeral environment, cheap and fast to spin up, so agents run more validations on their own before human review.
Unified Architecture
The same ephemeral environment covers local development and PR validation. One platform. One mental model.
Comprehensive Coverage
Jobs run your existing tests. Plans let agents build test workflows. All of it runs in your cluster.
Deep Isolation
Share a database or branch it per ephemeral environment. Queues stay shared, with messages routed by key. Resource plugins create cloud resources outside Kubernetes.
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 BraaSoftware 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 TavaresStaff 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 MarienSenior 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.
Jony JeyaratnamHead of Engineering Coding agents
Most code is now written by coding agents, on laptops and in the cloud. Each one gets its own ephemeral environment to test in, the same kind a developer uses.
Testing
Signadot runs your tests too. Telepresence does not.
Cloud native stack
Signadot routes through the mesh you already run. On Istio it adds no sidecar of its own: it updates your VirtualService rules and Istio does the routing.
Deployment and security
Most of Signadot runs in your cluster.

Works with your coding agents
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.
Naomi KleinLead Infrastructure Engineer at Laurel Yes. Run the service you are changing on your laptop with signadot local connect, or let your coding agent do it, on your laptop or in the cloud. Your code joins an ephemeral environment, so requests for your change reach it and nobody else's do. The same environment then serves your PR and tests: one model instead of two tools.
Telepresence is a network tunnel: it connects a program on your laptop to the cluster and sends it the cluster's traffic. Signadot is built on the ephemeral environment, one model for local development, PRs, tests and coding agents. The environment you or your agent develop in is the one your PR and tests use.
The open source project still ships releases, but no company sells support or an SLA. Ambassador Labs moved its paid Telepresence features into Blackbird, and Gravitee, which bought Ambassador in July 2025, offers neither. One maintainer writes most of the code, and the project's only sponsor ended its sponsorship in October 2026. Help comes from GitHub and the CNCF Slack.
Yes, with any database or queue. Resource plugins create a database for each environment, using tools you already use. Queues stay shared, and each message reaches the right environment. The same works for Temporal. The complete guide to ephemeral environments compares the approaches. Telepresence has no database or queue isolation.
Signadot is hybrid. Most of it runs in your cluster, with a small cloud control plane that only sees resource metadata by default. Need fully self-hosted? Talk to us.
Yes. On Istio it is native: Signadot updates the routing rules in your VirtualServices and Istio routes the traffic, in sidecar or ambient mode, with no extra sidecar to install. With the Gateway API, Signadot adds routes beside your HTTPRoutes and GRPCRoutes. With Linkerd or no mesh, a lightweight DevMesh sidecar routes requests. The routing key travels in the OpenTelemetry baggage header your tracing libraries already pass along.
Yes. Coding agents such as Claude Code and Cursor connect through Signadot's MCP server and agent skills. Each agent gets its own ephemeral environment, whether it runs on a developer's laptop or as a background agent in the cloud, and runs Jobs and Plans against it before anyone reviews the change.
