Simple Agent Manager — Open Source & Self-Hosted

The orchestration layer for
autonomous coding agents

SAM orchestrates Claude Code, Codex, Gemini CLI, or Mistral Vibe on your cloud VMs — provisioning real devcontainer environments, managing lifecycles, and opening PRs autonomously. Bring your own Hetzner or Scaleway account, pick an agent, and let it build.

I'll refactor the authentication middleware to use JWT validation. Let me read the current implementation first.

Agent orchestration
on infrastructure you own

Everything you need to run coding agents on your own cloud.

Multi-Agent Support

Claude Code, Codex, Gemini CLI, or Mistral Vibe — pick the right agent for the job. Bring your own API keys.

Bring Your Own Cloud

Your code runs on your VMs. Credentials encrypted per-user. You control costs, regions, and data residency.

Real Dev Environments

Agents work inside your repo's devcontainer — same toolchains and test runners your team uses.

Structured Visibility

Watch agents in real time — tool calls, file diffs, permission requests. Not raw terminal output.

Chat-Driven Tasks

Describe what you need. SAM provisions a VM, builds the devcontainer, and runs the agent.

Open Source & Self-Hostable

AGPL-3.0 licensed. Self-host on Cloudflare's free tier. No vendor lock-in.


From zero to coding agents in minutes

Four steps to coding agents working through your backlog on cloud VMs.

01

Connect Your Cloud

Add your Hetzner or Scaleway API token. Credentials encrypted per-user.

02

Create a Project

Link a GitHub repo. SAM organizes tasks and workspaces per project.

03

Describe Your Task

Type what you need. SAM provisions a VM, builds your devcontainer, and runs the agent.

04

Watch It Build

Stream agent output in real time. Get notified when the agent needs input or finishes.


How SAM stacks up

Own your infrastructure. Choose your agent. Pay cloud prices.

SAM
Managed AI Platforms Devin, Ona
Self-Hosted CDEs Coder
Your code runs on Your cloud (Hetzner, Scaleway) Their infrastructure Your infra (AWS, GCP, K8s)
Agent choice Claude Code, Codex, Gemini CLI, Mistral Their proprietary agent Varies (Claude, Gemini, OpenAI)
Open source AGPL-3.0 license Proprietary Open-source core
Control plane Free (Cloudflare Workers) Bundled into pricing You host it (K8s / Docker)
Infrastructure cost ~$4–15/mo (direct to provider) From $20/mo (compute + inference) Your cloud bill + license fees
Self-hostable Fully — control plane + VMs No Yes — Terraform + K8s required
Setup effort Deploy to Cloudflare + connect cloud Zero config Terraform + cluster management
Data sovereignty Full — your cloud, your data Vendor-managed Full — your infrastructure

SAM infrastructure costs are compute only — bring your own API keys for AI providers. Managed platform pricing bundles compute and model inference.
