The open-source platform for
multi-agent workflows
Every agent runs in its own isolated container on your cloud. Run 5 or 500 in parallel — SAM handles provisioning, scheduling, and cleanup.
Agent workflows
on infrastructure you own
Everything you need to run coding agents on your own cloud.
Multi-Agent Support
Claude Code, Codex, Gemini CLI, Mistral Vibe, OpenCode, or Amp — 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.
Connect Your Cloud
Add your Hetzner, Scaleway, or GCP credentials. Encrypted per-user.
Create a Project
Link a GitHub repo. SAM organizes tasks and workspaces per project.
Describe Your Task
Type what you need. SAM provisions a VM, builds your devcontainer, and runs the agent.
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.

|---|---|---|---|
| Your code runs on | Your cloud (Hetzner, Scaleway, GCP) | Their infrastructure | Your infra (AWS, GCP, K8s) |
| Agent choice | Claude Code, Codex, Gemini CLI, Mistral Vibe, OpenCode, Amp | Their proprietary agent | Varies (Claude, 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.
