Agent Starbase · Self-hosted agent platform

AI coding agents.
Safely contained.

Start with the open-source Codex image, then add Claude Code, Gemini, Copilot, OpenCode, Pi, Cline, Continue, Grok Build, LLM, DeepAgents, Browser Use, OpenHands, and Bash through local installs or plugins. Submit a prompt from the web dashboard, watch the agent work in a live terminal, review the diff, approve the commit. A kernel-level firewall forces traffic through the configured proxy mode, and requests are logged.

What you get

Agents without the anxiety.

Most teams either trust their agents blindly or don't use them at all. Starbase is the other path: let agents work freely inside a sandbox that enforces isolation, logs everything, and keeps the final decision with you.

One dashboard for every agent

Submit a prompt, pick an agent and a working directory, stream the live terminal, review the git diff, approve or reject the commit — from desktop or your phone. No SSH, no juggling terminals.

Real isolation, not a sandbox flag

iptables blocks all direct egress at the kernel; every packet is forced through a Squid proxy that enforces the selected allowlist mode and logs requests. Non-root containers, setuid binaries stripped, and configurable CPU/RAM/PID caps defaulting to 1 CPU, 8 GB RAM, and 3072 PIDs.

Runs while you're offline

Cron recurring jobs, one-time scheduled runs, batch-submit queues, and dependency graphs on the built-in task board let agents keep moving while you are away.

Manager Mode

One agent orchestrates many. A manager job spins up sub-agents, delegates tasks, collects results, and synthesizes a final diff — all inside the same isolated stack. Included in the free tier.

Context Teleport

When a job hits rate limits or stalls, Teleport packages the git state, transcript digest, and task context into a bootstrap prompt and hands it to a fresh agent — even a different kind of agent. Nothing is lost, nothing re-briefed by hand.

$

Know what it costs

Usage dashboards track Claude windows plus persisted per-agent token and cost estimates. Budget caps, exports, per-user breakdowns, and anomaly alerts are available as gated cost controls.

Architecture

Four containers.
One very opinionated firewall.

The agent runs as a non-root user with setuid binaries stripped and resource caps enforced. Direct egress is blocked at the kernel. All traffic is forced through Squid.

You set the mode. The agent cannot override it.

1

Browser → Web UI

Live terminals, job queue, diff review, cost tracker, task board. Mobile-friendly.

2

Agent container

Non-root · setuid stripped · iptables egress blocked · 1 CPU / 8 GB / 3072 PID defaults.

3

Squid proxy

Domain whitelist enforced, every request logged, mode hot-swappable from the dashboard.

4

Filtered internet

Only what you allow, logged to the byte. EGRESS DENIED is a feature, not an error.

Pricing

Free core. Paid gates for hosting and cost controls.

The core platform is Apache 2.0 and self-hostable. Pro and Team gate selected hosting, cost, collaboration, and support features on the same codebase.

FAQ

Common questions.

What exactly does Agent Starbase do?

It's a self-hosted platform that runs AI coding agents inside Docker containers with real network isolation. The open-source image starts with Codex; optional local installs and plugins add Claude Code, Gemini, Copilot, OpenCode, Pi, Cline, Continue, Grok Build, LLM, DeepAgents, Browser Use, OpenHands, and Bash. You submit a prompt via the web UI, an agent works your codebase, and you review the git diff before anything merges.

How does the network isolation actually work?

Each agent container has iptables rules that block all direct outbound traffic at the kernel. The only allowed path is through a Squid proxy that enforces the configured allowlist and logs requests. Strict and Default modes keep egress limited to configured provider and tool domains; Open mode is an explicit elevated capability for unrestricted debugging. Copilot/GitHub and full-internet access are handled as per-job capabilities.

Can I run it on my laptop?

Yes. Run make start-open-source and open https://localhost:6886. First run generates random passwords — there are no default credentials. The full stack (agent, proxy, web-ui, postgres) runs in Docker Compose.

Is Agent Starbase actually open source?

The codebase is prepared for Apache 2.0 publication. The AgentStarbase name and logo are covered by a separate trademark policy so forks cannot impersonate the project. The public GitHub launch is tracked separately from the local release checklist.

Do you store my code or prompts?

Self-hosted deployments run on your infrastructure. Code, prompts, proxy logs, job logs, and database state stay in the stack you operate.

What is Manager Mode?

A flag you set per-job that gives the agent access to bin/sandbox — a CLI for starting, monitoring, and killing other agent jobs inside the same stack. The manager agent delegates sub-tasks to specialized sub-agents, waits for results, and synthesizes a final output. Useful for large refactors, multi-file migrations, and parallel test runs. It's included in the free tier.

Your first agent job in five minutes.

Clone it, run make start-open-source, and submit your first prompt — safely.
