Quick Start

The easiest way to get started with OpnForm is through our official managed service in the Cloud.
For self-hosted installations, please refer to our Deployment Guides. For local development, we provide a minimal Docker-based setup - check out our Docker Development Guide.

Codex worktrees

Codex creates an isolated local environment for each worktree. It uses a dedicated PostgreSQL Docker volume and local Laravel/Nuxt processes, so sibling worktrees do not share ports, data, or API configuration.
Use the Codex Start app, Reset DB, and Stop app actions when available. You can also run the scripts directly:
./scripts/codex-worktree-setup.sh
./scripts/codex-worktree-up.sh

The startup command prints the worktree-specific URL. Opening its root URL automatically signs in the local Codex admin (e2e@example.test / Abcd@1234). The seed also creates three forms, including five completed submissions across two public forms, so the dashboard and submission screens are immediately useful. Reset only the current worktree database with:
./scripts/codex-worktree-reset-db.sh

Run the browser suite against the running worktree with:
./scripts/codex-worktree-test-e2e.sh

License

OpnForm is open-source under the GNU Affero General Public License Version 3 (AGPLv3) or any later version. You can find it here.

Dual Licensing

OpnForm uses a dual-license model to make the project sustainable:
  • Core OpnForm (AGPL-3.0): The main application is free and open-source under AGPLv3, giving you the freedom to use, modify, and distribute it.
  • Enterprise Edition (Proprietary): Advanced features under api/app/Enterprise/ are available under our Enterprise License and Enterprise Terms. These features help fund ongoing development and keep OpnForm sustainable.

By offering Enterprise features alongside our open-source core, we can continue to invest in making OpnForm better for everyone while keeping the project financially sustainable.

Serve OpnForm on your own domain behind Caddy, Nginx or Traefik. Fill in your domain and copy the result. It's a starting point, some apps need their own base URL or extra headers set too.

Proxying opnform.example.com to http://opnform:80

Add this to your Caddyfile

opnform.example.com {
	reverse_proxy http://opnform:80
}

Check the logs first

Nine times out of ten the logs tell you exactly what went wrong.

  • In Portainer, go to Containers, click the container, then Logs. Or run docker logs <container>
  • Exit codes help too: 137 means killed, usually out of memory. 126 or 127 means the command inside the image is broken.

Port already in use

If deployment fails with "Bind for 0.0.0.0:8380 failed: port is already allocated", something else on your server is using that port.

  • Find what's using it: sudo ss -tlnp | grep :8380
  • Stop the other service, or pick a different host port. In 8380:80 only the left number is yours to change, the right one belongs to the app.

Running but the page won't load

The container is up but nothing appears in your browser.

  • Use your server's real IP: http://your-server-ip:8380. The 0.0.0.0 link Portainer shows isn't a real address.
  • Give it a minute after first deploy, opnform can take a while to initialise.
  • Make sure your firewall allows the port, e.g. sudo ufw allow 8380

Permission denied on volumes

If the logs show "permission denied", the app can't write to its data folder on the host.

  • Fix the ownership: sudo chown -R 1000:1000 /portainer/Files/AppData/Config/opnform

Image won't pull

Test the pull directly on the host: docker pull jhumanj/opnform

  • "manifest unknown" means the tag no longer exists. This template uses latest, so try pinning a specific version instead.
  • "toomanyrequests" is the Docker Hub rate limit. Log in with docker login to raise it.
  • "no space left on device" means a full disk. Reclaim space with docker system prune

"exec format error"

This means the image was built for a different CPU architecture than your server.

  • This image supports: amd64
  • Check yours with uname -m: x86_64 is amd64, aarch64 is arm64. Raspberry Pi and other ARM boards are the usual culprits.

Stack won't deploy

Compose stacks fail fast on small mistakes, and Portainer shows the reason just above the editor.

  • YAML only accepts spaces for indentation, a single tab breaks the whole file.

Raise an issue

Found something which isn't working as it should? Here's how to report it.

A Compose stack

OpnForm is a Compose stack, a set of containers defined in one file and brought up together by Portainer, then started and stopped as a single app.

The app image

An image is the app packed up ready to go, everything OpnForm needs bundled into one download. This template pulls jhumanj/opnform, which Docker fetches once (about 434 MB) and then starts your own copy from.

Where the image comes from

Docker pulls its images from registries, public libraries of ready-built apps. OpnForm's comes from Docker Hub, published by jhumanj.

Version tags

The bit after the colon in the image name is the version tag. Here it's latest, which always points at the newest build, so a redeploy can bump you to a newer release without you asking. Newest right now is 1.2.6. Pin a specific tag if you would rather stay on one version.

Which machines it runs on

Every image is built for particular CPU types. This one ships for amd64, so it runs on regular x86 PCs and servers, though not ARM boards like a Raspberry Pi.

Ports

A port is the door the app answers on. A mapping like 8380:80 means it's reachable on port 8380 of your server, where the left number is yours to change and the right one belongs to the app. Once it's running, open http://your-server-ip:8380 in a browser. It opens:

  • 8380:80, likely the web interface

Volumes

A volume is where OpnForm keeps its files so they survive an update or a restart. Without one, anything it saves would sit inside the container and vanish the moment it's recreated. This template mounts:

  • /persist from /portainer/Files/AppData/Config/opnform on the host

Networking

Nothing custom is set, so OpnForm sits on Docker's default bridge network: its own private space that reaches the outside world only through the ports it publishes.

Container name

Once it's deployed, Portainer names the container opnform. That's what you'll spot in the containers list and use in commands like docker logs opnform.

Platform

The platform is linux, the kind of system the container is built to run on. Docker and Portainer handle this on a normal Linux server.

Portainer app templates

Zooming out, this whole page comes from a Portainer app template: a short recipe telling Portainer how to set OpnForm up. Add the template list to Portainer once, then deploying OpnForm is a click rather than a wall of config.
