Kubernetes-native platform that moves Claude Code, Codex and custom agent containers off laptops onto your own infrastructure

Key differences

Kubernetes-native platform that moves Claude Code, Codex and custom agent containers off laptops onto your own infrastructure

  • Runs local and cloud and sandbox. Free and open source under AGPL-3.0 and self-hosted; you supply the model provider keys the agents run on
  • Includes a Docker sandbox. Listed for 48 of 194 tools in this category.
  • Supports headless CI workflows. Listed for 60 of 194 tools in this category.
  • Keep in mind: Files are changed by the agent container Agyn runs, such as the bundled Claude Code or Codex agent.

“Serverless scale-to-zero with auto-termination on idle: the first coding agent that gets sent home for standing around.”

What it is

Agyn is an open-source, Kubernetes-native agent orchestration platform for running any AI agent container at scale on infrastructure you control. It offers serverless scale-to-zero execution with auto-termination on idle, Terraform-managed agent configuration, per-conversation sandboxing, isolation of each MCP server in its own container, and zero-trust networking in which credentials never reach the model context. Spend caps apply per agent, team or organization, and RBAC, SSO and audit logs cover access. Pre-built Claude Code and Codex agents ship with the platform, and the whole control plane, overlay, database, object storage and a runner can be started in a local VM with one command.

Los Agentes on Agyn

Who are they?
The ruling
El JuezThe judge

La Jefa and El Amigo are four points apart because they are different buyers, and El Crítico prices the thing neither of them put on the invoice.

Adopt with conditions
Reasoning and trade-offs · AI analysis

La Jefa and El Amigo score this four points apart and neither is reading it wrong. She sees role-based access, single sign-on, audit logs and spend caps per team, which is the list her security questionnaire asks for. He sees a platform that a single developer has no reason to install. El Crítico names the cost both of them skipped: somebody has to run the cluster.

La Jefa wins, because this was built for her and El Amigo is answering a question it never asked. Adopt with conditions, the condition being an existing platform team that already operates Kubernetes; without one, El Crítico's objection becomes the entire project.

El AmigoThe friend

Pick Agyn if your problem is that sixty agents live on sixty laptops; pick almost anything else on this board if the problem is your own laptop.

6.0
Reasoning and trade-offs · AI analysis

The deciding trait is where the work happens. Agents stop being processes on a developer's machine and become workloads on infrastructure somebody operates, which is either exactly what you needed or completely beside the point. There is no middle audience here. If you are one person with one repository, installing this is a weekend you will not get back.

If you are the person who gets asked where the agents are running and cannot answer, this is the answer. Pick it when that question has already been asked twice. Pick a terminal agent when it never has.

El CríticoThe critic

The bundled agents are Claude Code and Codex in containers, so nothing here improves the agent; what it adds is a Kubernetes cluster you have to keep alive.

6.0
Reasoning and trade-offs · AI analysis

The failure surface moves rather than shrinks. Every task an agent was going to get wrong on a laptop it will get wrong in a pod, and now the pod can also fail to schedule, lose its overlay network or be evicted. The bundled agents are the same vendor CLIs everyone else runs, wrapped. The improvement is in where they run, not in what they produce.

What it does right is the local start. One command brings up the whole control plane in a virtual machine, so you can see the failure modes before you commit a cluster to them.

El ProfesorThe professor

The stated design principle is that credentials never enter the model context, with each conversation sandboxed and each MCP server isolated in its own container.

7.3
Reasoning and trade-offs · AI analysis
  1. Keeping secrets out of the context window is a structural answer to prompt injection rather than a filtering one, and structural answers survive model changes while filters do not. 2. Isolating each tool server in a separate container makes the trust boundary match the process boundary, so a compromised server cannot read the conversation it was called from. 3. Per-conversation sandboxing gives the same property to the workspace.

  2. All three are asserted in project documentation and none is accompanied by a published threat model or an audit, so a reader should record them as documented intent rather than verified behaviour.

La InversoraThe investor

AGPL-3.0 with no hosted tier is the classic dual-licence setup: give the software away, sell the exception to whoever cannot ship it. 229 stars says that is theoretical.

5.8
Reasoning and trade-offs · AI analysis

The licence choice is the business plan, and it is a sound one. A strong copyleft on a platform product means every vendor who wants to embed it needs a commercial exception, which is real pricing power over exactly the buyers who can pay. What is missing is the demand: two hundred and twenty-nine stars and no published commercial tier means nobody has asked for the exception yet.

Moat: the copyleft, plus the switching cost of infrastructure. Likely acquirer: a cloud vendor filling an agent gap in its platform catalogue. Position: safe to run, and worth watching for the day a hosted tier appears.

La JefaThe CTO

Zero licence cost across sixty seats, with role-based access, single sign-on and audit logs in the product, and spend caps set per agent, per team and per organisation.

7.0
Reasoning and trade-offs · AI analysis

This is the first tool in the category that answers the questionnaire without a follow-up call. Access control, directory login and an audit trail are product features rather than an upgrade tier, and the spend caps are the item I never get: a ceiling I set per team, before the invoice, instead of an alert after it.

The cost is headcount. Agents are declared as Terraform resources and run as scheduled workloads, which fits how we already deploy, but it needs the platform team that deploys them. Approved with conditions: the platform team owns it, and no product team gets a cluster.

El HackerThe tinkerer

AGPL-3.0 means a fork outlives the vendor, the chart installs from an OCI registry with helm, and the provider keys stay mine because I am the one supplying them.

7.8
Reasoning and trade-offs · AI analysis

Strong copyleft is the licence I want on infrastructure I depend on: whatever happens to the company, the code stays open and a fork stays legal. Installation is a helm chart pulled from an OCI registry, which means the whole platform is a values file I keep in version control rather than a console somebody clicks through.

Model access is my own provider keys, so the platform never becomes a reseller. What it will not do is run inference on my hardware; the agents it ships are hosted-model CLIs and the weights stay somebody else's. That is the one box unticked.
