Coding Agent Environments

A real environment for every coding agent.

Production-shape Kubernetes environments for Claude Code, Cursor background agents, Codex, and Windsurf. Real services, real dependencies, per-task isolation. The code your agent ships has been validated against your real infrastructure.

Coding agents are flying blind.

Agents building microservices and cloud-native software need real services to call. Without an environment that mirrors production, an agent can write code but can't exercise it. It falls back to mocks, opens a PR, and the burden of review lands on the engineers around it.

No services to call

Running locally or in a sealed sandbox VM, the agent can't reach the real services and dependencies the production system runs on. The code compiles. Whether it actually works in a microservices topology is anyone's guess.

Shared staging doesn't scale

One staging cluster can't host every developer and every background agent at once. Agents queued against staging spend their day blocked, retrying, or breaking each other's tests.

Review burden lands on engineers

When an agent can't exercise its own code, engineers absorb the work in review. PR queues grow faster than humans can clear them, and the rollback rate climbs with the volume.

Kubernetes environments built for coding agents.

An ephemeral environment for every task. Real services on every call, thousands of environments on the cluster you already run, validation that happens before review.

Real services on every call

When the agent needs to exercise its code, Signadot exposes the real services and dependencies the production system runs on. The agent validates against the same topology it will face in production, not a mock layer that drifts.

Thousands of environments, one cluster

Each task gets its own environment. Only the services the agent changed run as forks, and everything else stays on shared stable dependencies. Thousands of tasks run in parallel on the same cluster.

Validation before review

Inside its environment, the agent runs broad validation and debugs failures with skills. PRs land already cleared end-to-end, so reviewers spend time on judgment, not triage.

How it works

Realistic runtime, without duplicating the cluster.

Each task runs in its own ephemeral environment. Only the services the agent changed run as forks inside the environment. Traffic from the agent's code traverses real services end-to-end, landing on the fork where one exists and on shared stable dependencies everywhere else.

One cluster, many environments. Tasks share the same stable dependencies, and only the services the agent changed run as forks.
Per-task isolation. Each agent sees the changes it made, not the changes other agents are testing in parallel.
Real services on every call. Validation runs against the topology and data shapes the agent will face in production.
Seconds to provision. The agent calls MCP, gets an environment, and is exercising real services in seconds.

Whichever agent you pick, Signadot is the environment.

Same MCP-driven environment, every major coding agent. No lock-in, no per-tool integration.

Bring your own agent

Connect any agent through the documented MCP tool surface or the Signadot CLI. No agent-specific lock-in.

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.

Plug your agents into your real cluster.

Connect any MCP-compatible agent in minutes. Your agents reach real services, run real tests, and ship code that has already been validated against production-shape infrastructure.

Agent-native tooling

Built for agents to drive end to end.

Signadot exposes the cluster through MCP & CLI, composable Actions and Plans, and a library of agent skills. Together they let agents autonomously provision environments, run broad validation on their changes, and debug failures without a human in the loop. Your platform team keeps the guardrails through the same control plane developers use.

Read the docs

MCP & CLI

Direct interfaces the agent drives end to end. Provision environments, route traffic, ship Jobs, and inspect state through natural language or scripts.

Actions & Plans

Actions are reusable units of work: run a test Job, seed a fixture, flip a feature flag, hit a smoke endpoint. Platform engineers and developers author Actions once. Developers and agents compose them into Plans that match the workflow for a given change. Plans run on every task and stream results back into the agent loop.

Agent skills

Packaged capabilities for provisioning, validation, and debugging. Reused by the agent across every task so behavior stays consistent.

Coding Agent Environments FAQ

What is a coding agent environment?

A coding agent environment is the runtime where an AI coding agent does its work: the codebase, the services it calls, the dependencies it tests against, and the routing that lets it operate alongside production-shape infrastructure without breaking anything else on the cluster. Signadot provides this environment as a per-task overlay on your existing Kubernetes cluster.

How do I give Claude Code access to real services?

Claude Code connects to Signadot through the native MCP server or the Signadot CLI. The agent calls a single command to create a per-task environment that includes the services it changed plus access to every real service in your cluster. From Claude Code, the agent can run tests, hit real endpoints, and inspect responses against production-shape data.

How does Cursor background agents work with Signadot?

Cursor background agents that run remotely need a real environment to test in. Signadot gives each background agent its own ephemeral environment with full cluster access. The agent spins up the environment, exercises it, and tears it down without contending with developers or other agents.

Does this replace local development for agents?

No. Agents can still run code locally for fast iteration. Signadot sits underneath as the integration target: the place an agent reaches when it needs to talk to a database, hit a downstream service, or run an end-to-end test. Local development and the Signadot environment share the same routing model.

How is this different from giving agents a sandbox VM?

A sandbox VM gives an agent a sealed-off box with no real services. Signadot environments are connected: the agent runs in your real Kubernetes cluster, reaches the real services and dependencies it would hit in production, and tests against production-shape topology. The agent is isolated from other tasks, not from production-shape infrastructure.

Which agents are supported?

Anything that speaks the Model Context Protocol or can shell out to a CLI. Claude Code, Cursor, Codex, Windsurf, Aider, Continue, Zed, and custom in-house agents all work. The MCP server exposes Signadot environment operations as tools the agent can call directly through natural language.

Can a platform team govern what agents can do?

Yes. Environment creation and routing happen through the Signadot control plane, which supports RBAC, audit logs, per-cluster quotas, and resource limits. Platform teams keep the guardrails. Agents get autonomy inside them.

Give your agents a real place to work.

Spin up production-shape Kubernetes environments per task. Claude Code, Cursor, Codex, Windsurf, or your in-house agent reach the same cluster, the same services, and the same dependencies you ship to production.
