Spliit Spliit

Stack

Finance

Expense splitter for trips, flatmates and nights out, tracking who paid for what in a shared group and working out who owes who, with no accounts needed, just a link to the group. Handles several currencies, categories and uneven splits. Source: https://github.com/spliit-app/spliit

Notes

Set the database password before you deploy (openssl rand -hex 32 makes a good one), since the stack won't start without it, and keep it the same when you redeploy. Then open http://<your-host>:3800 (or whichever port you picked) and create a group. There are no accounts: anyone who can reach it can make a group, and anyone with a group's link can see and edit it, so share links with care and keep it off the open internet unless you mean to. Groups you've opened are listed in your browser, not on the server, so bookmark or save the link. Converting an expense from another currency asks api.frankfurter.dev for the rate, and the currency picker loads flags from flagcdn.com. Everything lives in Postgres, in the postgres-data volume.

Original stackfile

The compose file this template deploys, straight from its repo:

Or deploy it directly from the source:

git clone https://github.com/NotAFlightRisk/portainer-templates-extras
cd portainer-templates-extras
docker compose -f apps/spliit/compose.yml up -d

Container Documentation

postgres Documentation

The PostgreSQL object-relational database system provides reliability and data integrity.

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.

Image won't pull

Test the pull directly on the host: docker pull ghcr.io/spliit-app/spliit:latest

  • "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.

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

Container keeps restarting

The unless-stopped restart policy relaunches the app after every crash, so the real error can scroll past.

  • Check the logs right after a restart, the last few lines before it died are the useful ones.
  • Get the exit code with docker inspect <container> --format '{{.State.ExitCode}}'
  • Still stuck? Redeploy once with the restart policy set to no so the failure stays visible.

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

Spliit is a Compose stack, a set of containers (2 of them) defined in one file and brought up together by Portainer, then started and stopped as a single app.

The services

This stack is built from 2 containers that run side by side. Here's each one, with the image it runs and anything it waits for first:

  • spliit runs ghcr.io/spliit-app/spliit:latest, starts after postgres
  • postgres runs postgres:18-alpine

Volumes

A volume is where Spliit 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:

  • /var/lib/postgresql kept in the postgres-data volume Docker manages

Environment variables

Environment variables are the settings you hand over when you deploy, things like a password or a timezone. Spliit takes 5 of them, and one needs a value before it'll start properly:

  • POSTGRES_PRISMA_URL, defaults to postgresql://spliit:@postgres:5432/spliit
  • POSTGRES_URL_NON_POOLING, defaults to postgresql://spliit:@postgres:5432/spliit
  • POSTGRES_DB, defaults to spliit
  • POSTGRES_USER, defaults to spliit
  • POSTGRES_PASSWORD, needs a value

Restart policy

The restart policy here is unless-stopped, so Docker restarts Spliit after a crash or reboot, but leaves it off when you stop it on purpose. You can change this on the deploy screen. The choices are no (never restart), on-failure (only after a crash), unless-stopped (restart unless you stop it), and always (bring it back no matter what).

Networking

Portainer puts these services on one shared private network, so they can find each other by name (like spliit) while only the ports above are open to you.

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.

Open source license

Spliit is open source, released under the MIT license. In plain terms the code is out in the open, so you're free to run it and change it to fit what you need.

Portainer app templates

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