Ployz

Ployz

Rent a server. Get a cloud.

Preview environments on servers you own. One command from a fresh server to https.

Website · Quick start · Agents · Status · Self-host

Ployz turns Linux servers you rent into a deployment platform. It builds your app, gives it an https address and runs its databases and workers next to it. Every pull request can get its own environment. Start with one server and add more when you need them.

The workflow of the hosted platforms you like, on servers you rent.

Six hosted platforms. Ployz isn't affiliated with any of them.

What's different

• An environment for every pull request. Each preview runs the pull request's code at its own https address. Copy the database service and the preview gets its own empty database, seeded by your setup command. A database you leave shared gives the preview production data. On merge, production gets the code and the preview's setting changes. The Ployz · ready to merge check lists those changes on the pull request first.
• Review before you deploy. Edits from the dashboard, the CLI or an agent wait as a draft. You read the diff, then deploy it.
• The CLI does what the dashboard does. Commands print JSON with --json. A change that would delete a service, a volume or a domain stops until a person approves it. An agent can't approve it.
• One private network across your servers. Add a server with ployz server add. Your servers share a WireGuard network, and a service runs up to 50 replicas across them. A service with a volume runs on the server that holds its data, one replica by default.
• Apps that outlive Ployz Cloud. Your apps keep running on your servers if Ployz Cloud is down or goes away. The engine and the dashboard are open source.

Use it with your agent

Paste this into your coding agent.

It installs the CLI and the Ployz skill, signs you in and registers the Ployz MCP tools. From then on it runs the same commands you would.

> Copy production with its own worker, deploy it there, then stage it back.

$ ployz env branch try-worker --copy worker # Made Branch shop/try-worker of production. $ ployz deploy --env try-worker # 2 deployed · across 1 server $ ployz env sync --env try-worker --to # Synced try-worker → shop/production.

The change waits in production for you to review and deploy.

Quick start

You need a Linux server with systemd that you can reach as root over SSH. See the server requirements.

1. Install the CLI.

   curl -fsSL https://ployz.sh | sh

1. Sign in to Ployz Cloud.

   ployz login

1. From your app's directory, point Ployz at your server.

   ployz up --server root@your-server

Ployz installs itself on the server, builds your app and prints its https address.

1. Deploy on every push, and give each pull request a preview with its own seeded database.

   ployz github connect                # install the Ployz GitHub App

ployz set shop.repository=you/shop # build from GitHub instead of uploads ployz deploy ployz env pr you/shop --on --from production --copy postgres --setup 'shop=pnpm db:seed'

ployz up names the service after your app's directory, here shop. The preview copies a postgres service you've added.

How it works

Each server runs a small Ployz daemon next to Docker. Your servers share a WireGuard network and keep each other up to date. Every server serves https itself through Caddy, so there's no load balancer to rent. The dashboard and the CLI tell your servers what to run. Once deployed, your apps depend on neither. Generated ployz.app addresses use Ployz's DNS. A custom domain with an A record pointing at your servers doesn't.

Status

Can I move a production app? Yes, if the gaps below are fine for you. If you need managed backups and automatic failover today, wait. Ployz is young and changes quickly. Work through the production checklist first.

• You look after the OS. Ployz doesn't install OS updates.
• No offsite backups yet. Volume mirrors keep a copy on another server. Dump your databases on a schedule and keep the dumps off your servers, or keep your hosted database.
• No automatic failover. If a server dies, what ran only there stops. Replicas on other servers keep running.
• No Docker Compose files. Add each container as its own service.
• Alerts are email only. Ployz Cloud emails you when a service goes down or crashes.

Soon: offsite backups, automatic rollbacks, and moving a database to a bigger server without downtime.

Pricing

Ployz is free on your own servers, custom domains included. Paid Ployz Cloud plans are coming soon. Your hosting provider bills you for the servers.

Self-hosting the dashboard

Run the dashboard yourself instead of Ployz Cloud. See dashboard/README.md.

How Ployz is built

Agents write most of Ployz. I design the loop they run in, and I answer for what comes out of it.

Every change ships as a small PR. The agent has to prove it by running Ployz the way you would, on real servers. If it can't show me that, it doesn't merge. Low-risk PRs merge once the checks pass. The orchestrator, networking and anything touching your data get a human review first.

When an agent gets something wrong, we turn the mistake into a lint rule or a test. Every mistake makes the system stricter, and that's the part I trust.
