Spliit review: split shared expenses privately

Spliit is a free open-source expense splitter for a trip, a shared flat, or any bill several people pay together.¹ You write down who paid, see who is ahead, and share one link so the group looks at the same list. There is no account and no advertising on the public site.¹ Sebastien Castiel runs that site, and you can also run your own copy so the records stay on a server you control.²³

What Spliit does (and how it protects your privacy)

Spliit keeps a group ledger. You add each expense, mark who paid and who shares the cost, then see the balances and the transfers that settle the group.¹³

There are no user accounts. You are not asked for an email or a password, and nothing you do is attached to an identity. The link is the only way in, and anyone who has it can read and change the group.² On the public site those records stay on the server while the group exists. A copy you run yourself keeps them off spliit.app.²³

Key features of Spliit

Groups you share with a link. One group can cover travel, an event or a gift.¹
Even and uneven splits. Divide a cost by percentage, by shares, or by an exact amount.¹
Categories and search. Each expense can have a category, and you can search the list later.¹³
Receipts. Attach a photo of a receipt to the expense it belongs to.¹
Balances and reimbursements. See what each person spent, and record a repayment as its own expense.¹³
Phone and your own server. It is a progressive web app, a site you use in the browser. The iPhone app reads receipts on the device and keeps your group list in iCloud. A container plus PostgreSQL, the database that stores the groups, runs a private copy.³⁵

Pros and cons

Pros

The public site is free, has no ads, and does not ask anyone to create an account.¹
The code is under the MIT licence, so a household can run its own copy.⁴
Someone can add an expense from a phone browser without installing an app.⁷
On iPhone, receipt reading stays on the device, and the public site’s visit statistics leave out the group identifier.²⁵

Cons

Anyone with the group link can see and edit the expenses. There is no separate login.²
On spliit.app, the app cannot delete a whole group from the server. You email [email protected] with the link.²
In a browser, your list of groups stays on that device. A new phone starts empty until you open the links again.²⁷
There are no notifications and no built-in payments. Spliit records the debt; it does not move the money.⁷
On the website, scanning a receipt sends that picture to OpenAI, and a category suggestion sends the title you typed.²
The current iPhone and iPad app needs iOS 26 or iPadOS 26, and the store listing is in English and French. Older iPhones keep the last version that still runs.⁵⁶

Is Spliit safe and private?

Sebastien Castiel develops Spliit and operates spliit.app. The source is public under the MIT licence, and version 1.30.0 of the web app was published on 11 October 2026.²⁴⁸ The README names Vercel as the host for the application and its database. Donations pay for that hosting, and Open Collective shows a public ledger of what comes in and what it is spent on.³

Traffic to and from Spliit is encrypted, which means the connection is scrambled between you and the server. There are no passwords, because there are no accounts, so a group stays private only while its link stays with the right people.² The server stores the group name, description, currency, participant names, and each expense’s title, amount, date, category, payer, split and notes. An attached receipt goes to that instance’s file storage.²

The public site counts visits with Umami, a cookieless counter that sets no identifier. Group identifiers are removed before anything is sent, and events do not include what you typed. One cookie remembers your language. Short-lived logs can include the network address.² On a copy you host, analytics stay off unless you turn a provider on.³

Website receipt scanning sends the picture to OpenAI, only when you use it. The privacy policy says OpenAI’s API terms mean that picture is not used to train their models. On the website, a category suggestion sends only the title.² On iPhone the picture is read on the device, and it is not uploaded unless you attach it.⁵ The App Store label says the app collects no data.⁶ You can delete one expense yourself. Deleting a whole group on spliit.app means emailing [email protected].² On your own server, deletion stays off until you enable it, and a group can be restored for 30 days.³

How to get started with Spliit

Open spliit.app in your browser. That is the official site.
Create a group, name it, and add the people who share the costs.²
Tell the app which name is yours, so balances can be shown from your side.³
Add an expense with a short description, the amount, who paid, and how to split it.¹
Send the group link only to the people in the group. Anyone who opens it can view and edit the list.²
On iPhone or iPad, install Spliit – Shares Expenses from the App Store. The seller is Sebastien Castiel. The current app needs iOS 26 or iPadOS 26.⁶
To keep the database yourself, follow the project’s Docker instructions for the app and PostgreSQL. Receipt uploads and website receipt scanning stay off until you add file storage and, for scanning, an API key.³

Who should use Spliit (and who might prefer something else)

Spliit fits a trip, a flatshare or a one-off collection where people already trust each other. The group gets a link, a few names and a running balance, without reminders or a payment button inside the app.

For another open-source take on shared expenses, see the Academy’s guide to I hate money. For your own spending, rather than a group tab, Firefly III is a self-hosted finance dashboard, and GnuCash keeps household accounts on a desktop. Spliit’s maintainer describes the missing account as a deliberate choice.⁷
