One installer, every tier Starter, Standard, and Pro are the same software, not separate downloads — what changes is whether (and how) you register a license after installing, not which file you get here. Pick the option below based on how many machines you're setting up, then register for Standard or Pro afterward if that's your plan. Starter needs no license at all.

One machine (Starter tier, or any small company)

Running TStamp for yourself, or a small company on a single workstation or server — this is almost always the right choice. One installer sets up the client, the TStampAPI server, and a local SQL Server Express database together, all on one machine. Other users (if any) get the lightweight client-only install below, pointed at this machine.

Full bundle — TStampSetup.exe

Client + TStampAPI + local SQL Server Express, one machine. Start here if you're not sure which one you need.

Multiple machines / your own server

Bigger companies, or anyone running TStampAPI on its own server (with or without an existing SQL Server instance) and connecting other people's computers to it as clients.

Client only — TStampClientMsi.msi

The lightweight desktop client, for every computer besides the one running TStampAPI. Just needs a server address.

API bundle — TStampApiSetup.exe

TStampAPI on its own server machine, without the desktop client — typically paired with an existing SQL Server instance rather than a local one.

Database only

A script and README for a DBA to provision the TStamp database by hand, on its own schedule — not an installer, no IIS/API setup included.

Mobile (Android / iOS)

Mobile is a separate distribution channel from the downloads above — not a file from this page. Contact Ollam for current Android/iOS distribution options.
Running TStamp on external/cloud hosting? Hosting TStampAPI on managed hosting (Azure App Service, or similar) rather than your own on-prem server isn't one of the downloads above — there's no installer for that, since it's a deployment done directly on the hosting platform rather than a file you run. Get in touch with Ollam to talk through what that would look like for your setup.
