Switching from Tower to Spire: what stays, what gets better
An honest migration guide for Tower users. What you recognise right away, what feels different and why one-time purchase instead of a subscription is the real difference.

Up front: Tower is a good tool
Let us start honestly. Tower has matured over many years, has a loyal user base and does a lot right. If you are happy with Tower and the subscription works for you, there is no reason to switch in a hurry. This text is not an attack on Tower, but an orientation for everyone who is thinking about switching for a concrete reason, usually because they want to buy and own a tool instead of renting it indefinitely.
The real difference: one-time purchase instead of a subscription
The clearest dividing line is the pricing model. Tower and some other clients such as GitKraken rely on a subscription. Spire is a one-time purchase. You pay once, the version is yours, and it keeps running even if you stop paying. Updates within the purchased window are included, and after that you keep the last version you received.
That is not a small thing. A tool you use every day should belong to you and not become a hostage every time an invoice lapses. That very stance is the reason Spire exists.
What you recognise right away
The switch is smaller than you think, because Git under the hood is the same. Your repositories, branches, remotes, tags and stashes are Git objects, not a proprietary format. You open an existing repository in Spire and see the same history, the same branches, the same state. There is nothing to migrate and nothing to export.
The basic gestures are familiar too. View changes, stage, commit, push, pull, merge, switch branches. Anyone who has worked with a graphical Git client finds their way in minutes.
What feels different
Spire is built with SwiftUI and AppKit, so it is genuinely native on the Mac. You notice it in the scrolling, in diffs that appear instantly, and in the fact that the app feels like a Mac program and not like a website in a window. For users coming from one of the Electron based or Java based clients, this difference is especially clear.
Spire also ships its own Git. You do not have to install anything on the command line, and Spire works even on a freshly set up Mac without any Git installation.
Features Tower users watch for
A few things that matter in the daily flow and are present in Spire:
- Line staging. You can stage individual lines of a change, not just whole files, and build precise, self contained commits.
- Conflict handling. Merge conflicts are kept as a clear list, with a structured view of both sides.
- Undo. Many actions can be undone, which raises the courage to experiment.
- Bundled Git. No separate installation needed.
Here is the honest part too. Tower is older and has accumulated a wide breadth of detail features over the years. Spire is younger and focused. If you depend on a very specific Tower feature, check before switching whether Spire already has it. Spire's way is to make the important things first class, rather than covering every niche right away.
A gentle switch in three steps
- Install Spire and open one of your existing repositories. Nothing is changed, you are just looking at the same Git through a different window.
- For a few days, do the everyday things in Spire: view, stage, commit, push. Feel free to keep Tower alongside, there is no need for a hard cut.
- Once Spire feels right, make it the default. Your Git data was the same all along, only the tool you view it with changes.
Who the switch is worth it for
The switch is worth it above all if three things matter to you: owning a tool instead of renting it, real Mac nativeness instead of a wrapped website, and a focused, calm program for daily work. If that sounds like you, download Spire and open a repository. The best test is a normal working day.
