AMUX is an open-source agent multiplexer that lets you run dozens of Claude Code (or other terminal AI coding agents) simultaneously, all managed from a single web dashboard — no complicated setup required. Built by the team at Mixpeek, it requires only Python 3 and tmux, with the entire server delivered as a single ~23,000-line Python file with embedded HTML/CSS/JS. The standout features are a self-healing watchdog that auto-compacts context when it drops below 20% and restarts stuck sessions, a SQLite-backed kanban board where agents atomically claim tasks to prevent duplicate work, and a REST API injected at startup that allows agents to coordinate with each other via simple curl calls. There's even a mobile PWA with offline support via Background Sync so you can monitor your agent army from your phone. In the "agentmaxxing" era, AMUX is the most complete open-source solution for running parallel AI coding agents unattended. Rather than babysitting one agent, you dispatch 5–20 agents to isolated worktrees and check back in as a reviewer. The MIT + Commons Clause license means it's free to self-host.

Fixa is a cloud-native AI coding agent that goes beyond code completion to handle end-to-end project scaffolding, deployment, and iterative refinement — all without any local setup. Launched on Product Hunt today, it lets developers describe a project in plain language and returns a running, deployed application within minutes. Unlike Bolt, Replit, or Lovable — which run in browser-based sandboxes — Fixa provisions real cloud infrastructure (compute, database, CDN) on your behalf and maintains persistent agent state between sessions. You can leave a session and return to find the agent has continued iterating on your project based on usage data it collected from real traffic. The differentiator is the feedback loop: Fixa monitors the deployed app's error logs and user interactions and proactively proposes fixes or improvements without being asked. It supports Node.js, Python, and Go projects, connects to GitHub for version control, and integrates with Stripe, Supabase, and Cloudflare out of the box.
Reviewer scorecard
“This is exactly what the agentmaxxing workflow needs. Single Python file, no external services, and the kanban board preventing duplicate agent work is genuinely clever engineering. The self-healing watchdog alone saves hours of babysitting stuck sessions.”
“The persistent agent state between sessions is genuinely new — most AI coding tools forget everything when you close the tab. The automatic error monitoring and proactive fix proposals are early-stage but already useful for catching dumb mistakes in side projects.”
“MIT + Commons Clause isn't really open source in the traditional sense — you can't build a commercial product on top of it. Also, coordinating 20+ agents that all share Claude Code rate limits means you'll hit API throttling walls faster than you think.”
“Letting an AI agent autonomously modify production code based on user behavior data is a significant trust leap. The free tier is one project, and cloud infrastructure costs aren't fully transparent at signup. Wait until the auto-deploy feature has more community vetting before pointing it at anything real.”
“We're moving from one developer + one agent to one developer + agent swarm. AMUX is early infrastructure for that paradigm shift. The agent-to-agent coordination REST API hints at genuine multi-agent systems emerging from terminal tooling.”
“This is what 'AI-native software development' actually looks like — not just autocomplete, but an agent that's accountable for the running system. The feedback loop from production traffic to code changes is a glimpse at how most software will be maintained in five years.”
“The web dashboard with live terminal peeking is surprisingly polished for a side project. Being able to monitor your agent army from a mobile PWA while away from the desk is a genuinely practical touch.”
“For non-technical creators who want to ship a product without learning DevOps, Fixa removes the biggest friction points: hosting, databases, and deployment. I spun up a newsletter landing page with a waitlist in under 10 minutes.”
