Install first, prove the exact workstation, then train with sample records. Keep shop data out until the device path is understood.

Try the hosted demo first

Use the public supermarket demo from the POS README. It has one-tap logins for admin, manager and cashier, a week of sample trading, and an hourly reset.

Email, SMS and password changes are disabled there, so you can test without touching real shop records.

Or run it on your own server

Install Posnic on a server you control

Same free software, on a machine you own, reached from a browser on any till, tablet or phone on your network. Your data stays on your disk.

One command on Ubuntu 24.04

curl -fsSL https://raw.githubusercontent.com/Posnic/POS/main/scripts/install-server.sh -o install-server.sh
less install-server.sh      # read it first
sudo bash install-server.sh

Installs Node.js, MongoDB and Posnic, runs it as a service, and prints the address to open. Needs about 2 GB of memory.

What you get

  • The whole local edition, in a browser
  • Several people using it at once
  • Your data on your own disk
  • No trial clock, no account, AGPL-3.0

What you take on

  • Updates, backups and a certificate are yours to run
  • Sync between separate tills or branches is not included — that is Posnic Cloud
  • A server is a machine somebody has to look after

Read the self-hosting guide → certificate, firewall, backups and updates

If one person rings up sales on one computer, the desktop app above is the right answer and always will be. A server is worth it when several people need the same till data at the same time.

Inspect the real inventory workflow

This is a Posnic product screen, not a stock illustration. The inventory log records opening stock, movements and closing stock so a shop can trace why a quantity changed.

Verify before installing

Know what the package includes

Use the checksum, source and platform guidance below when the software will hold real sales or stock records.

Free means local edition

No trial clock and no Posnic account are required for the local desktop edition. Cloud sync, managed off-site backup and remote dashboards are optional services.

Database included

The desktop package includes its local database and API. Keep a tested backup away from the till because local data is your responsibility.

Checksums published

Every listed package has a published SHA-256 value. Compare all 64 characters before testing the file with business data.

Verify the exact file before you run it

The release workflow publishes a SHA-256 list for all eight installable v1.6.1 packages. A matching SHA-256 proves that your file has the same bytes as the published release asset. It does not prove that the software is safe, suitable for your shop or approved by your device policy.

Provenance boundary. The v1.6.1 release notes state that the published artifacts are provenance-attested by GitHub. The linked evidence file remains the earlier publisher verification record and explains what an attestation proves and does not prove. Inspect the exact evidence and limitations.

  1. Record the exact file name, operating system, processor architecture and published byte size.
  2. Compute the full local SHA-256. On Windows use Get-FileHash -Algorithm SHA256 "path-to-file"; on macOS use shasum -a 256 "path-to-file"; on Linux use sha256sum "path-to-file".
  3. Compare all 64 hexadecimal characters, retain the result, then test with synthetic data and a clean profile before using business records.

The record starts with every observation, evidence, owner, review, pass/fail and follow-up field blank. Microsoft documents Get-FileHash; platform warnings still require a separate security decision.

Signed installers and platform checks

The v1.6.1 release notes describe Windows as signed and timestamped, and macOS as signed and notarized. If your operating system still warns about publisher identity, stop and verify that you downloaded the file from this page or the linked GitHub release.

Windows. SmartScreen also uses reputation information, so a new app can still trigger extra caution on some devices. Check the publisher, checksum and source before allowing the file. On a managed computer, follow the administrator's decision. Read Microsoft's current App & browser control guidance.

macOS. Gatekeeper should recognize the signed and notarized build. If macOS blocks a file, verify the checksum and source before continuing. Apple warns that overriding this protection can expose the computer to malware; read Apple's current safe-app guidance. Do not remove the quarantine attribute with a terminal command.

Linux. The GitHub release includes checksum files and detached GPG signatures for the direct AppImage and Debian package. The release notes also point Linux users to the signed APT repository for ongoing updates.

Start from this canonical page or its linked GitHub release and check your file against SHA256SUMS.txt before installing. Keep your own backups because any POS release can hold sales records.

Inspect and build the pinned source

The whole application is AGPL-3.0 open source. The public v1.6.1 artifacts are built from the release tag by the repository's release workflow. Pin the source input before installing dependencies:

git clone --branch v1.6.1 --depth 1 https://github.com/Posnic/POS.git cd POS git rev-parse HEAD # expect 567a176b665bc9bbe4e14e72497b39e09bceda25 npm ci npm --prefix frontend ci npm --prefix api ci npm test

A complete installer also needs the platform-specific bundled MongoDB and packaging preparation. Follow the pinned release workflow. The successful v1.6.1 release run checked out the tag at the reviewed commit in its Windows, macOS, Linux and publish jobs. A local build is not assumed to be byte-identical to the published artifact because the runner, dependencies and packaging environment also matter. Inspect the reviewed source commit.

Download questions

Is Posnic POS really free to download?

Yes. The local desktop edition is AGPL-3.0 open source with no trial clock. Optional cloud sync, managed backups and remote dashboards are separate paid services.

Which operating systems can run Posnic?

v1.6.1 publishes Windows x64 installer and portable files, macOS builds for Apple Silicon and Intel, and Linux AppImage and Debian packages.

Does the Windows portable build leave data on the computer?

The file needs no installer, but Posnic still creates application data in your user profile unless you deliberately configure another user-data directory. Portable does not mean stateless.

How can I verify a Posnic download?

Choose the exact operating-system and architecture file, then compare its full local SHA-256 with SHA256SUMS.txt. A matching hash proves byte identity with the published asset, not safety or shop suitability.
