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.
Describe what you want.
Watch it happen.
Talk to your agents like teammates. Pick the right model for the job, attach files, and watch them write code, run tests, and open PRs — all from a single chat.
Multiple agents, one interface
Switch between Claude Code, Codex, Gemini CLI, Amp, and more — each configured with their own API key or OAuth token. Choose the right agent for the task without leaving the chat.

Real-time visibility into agent work
Tool calls, file edits, and shell commands are streamed to your browser as they happen. You can read every step the agent takes and cancel at any time.
Explore Chat-First DevelopmentSee everything.
Stay in control.
A dashboard for all your agent work. Track active tasks across projects, monitor node health, and get notified when agents need your attention.
Multi-project dashboard
See active tasks with their status, project, and timing. Below that, a project grid shows workspace counts, session counts, and last activity for each repo.

Infrastructure you can see
Each node card shows its provider, spec, pricing, CPU/memory/disk usage, and the workspaces running on it. Create new nodes or add workspaces from the same page.

Never miss a decision point
Notifications are categorized by type — task completions, errors, progress updates, sessions ended, PRs created, and moments where agents need human input. Filter to focus on what matters.

Agents that remember
your preferences.
Build a project knowledge base that agents receive as context. Set policies that are injected into every session. Review a full log of agent activity.
Persistent project memory
Store observations about your architecture, conventions, and preferences. Each entry has a confidence score, a source (explicit or inferred), and a confirmation date so you can see what the knowledge base contains.
Explore Agents That Learn
Project policies
Define project-level instructions like "use portals for modals" or "CLI packages must meet QA standards." Policies are tagged as preferences or rules and injected into every agent session as context.
Explore Agents That Learn
Activity log
A timestamped feed of every task submission, execution step, session start/stop, and agent completion event. Filter to find specific activity across the project.
Explore Agents That Learn
From idea to
agent-ready task.
Capture ideas with a problem statement and plan. Schedule recurring tasks on a weekly or daily cadence. When you are ready, dispatch an agent with one click.
Structured idea capture
Write down the problem, sketch a plan, and link related chat conversations for context. When you are ready, hit Execute to dispatch an agent that picks up the idea as a task.
Explore Idea to Execution
Recurring triggers
Schedule agents to run dependency updates, spot checks, audits, or other recurring work on a daily or weekly cadence. Pause, resume, or run manually any time.
Explore Idea to Execution
Fully configurable.
Open source.
Upload reference docs, choose your VM size, and pick a default agent — each project has its own settings for infrastructure and agent configuration.
Project library
Upload architecture docs, research, and reference material. Files are organized with folders and tags. Agents can access library files as additional context during their work.
Explore Your Project, Your Way
Built-in document viewer
Markdown files render with full formatting, including Mermaid diagrams. Toggle between the rendered view and raw source, or download the file directly.
Explore Your Project, Your Way
Infrastructure and agent defaults
Choose a default node size (Small, Medium, or Large with specs and pricing shown) and a default agent type for each project. Per-agent credential overrides let you configure API keys at the project level.

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.
