Pulse Pro is a professional macOS app that allows you to view logs in real-time. The app is designed to be flexible, expansive, and precise while using all the familiar macOS patterns. It makes it easy to navigate large log files with table and text modes, filters, scroller markers, an all-new network inspector, JSON filters, and more.
Remote Logging #
The headlining feature of Pulse Pro is Remote Logging which allows you to view logs and network requests in real-time on your Mac. It’s very easy to use, fast, and reliable. To starting using it, first launch the Pulse Pro app and enable Remote Logging.
When enabled, your Mac becomes discoverable on your local network. You only need to enable it once. Next time you launch Pulse Pro, it will happen automatically.
Then, enable Remote Logging on the device with the Pulse framework installed. When your Mac appears on the list, select it to pair the devices. This extra step is needed to ensure that in a space with multiple devices running Pulse Pro, you’ll have a way to choose which one to connect to. You only need to do the pairing once.
Pulse is written in SwiftUI and is available on all Apple platforms. The same is true with remote logging. It works on iOS, watchOS, tvOS, and macOS if you need to. And it even works in simulators.
As soon as the devices are paired, there is zero additional interaction needed. When the device connects to the Pulse Pro app, the console opens automatically. You can turn this option off later in settings. And the device remembers which Mac it is paired with, so the next time it’s launched, it will connect right away without your interaction.
The logs are stored persistently both on the device with the Pulse framework and by the Pulse Pro app, so you can get back to them later. You can also easily delete them if needed.
Table Mode #
Mac apps are flexible and adjust to how we individually use them. When you launch the console for the first time, you are greeted with a simple and clean view with only a few columns and no details panel. You can remove and hide columns, and the app remembers your choice. And, of course, you can sort by a column. The high information density and flexibility allow you to really interact with your data.
When you click to select a row, the details panel is open. You can select between vertical and horizontal layouts, and your choice is saved. If you double-click, the details are opened in a separate window instead.
Filters were also fully redesigned. You know how in many apps you configure the filters, but then your only options are to either reset them all or change them back to the defaults manually. In Pulse Pro, you can toggle and reset each filter individually, which is surprisingly convenient. You can collapse the sections you rarely use, and the app saves your preferences. To show filters, hit
Cmd+Option+F or click the toolar item.
Text Mode #
Tables are perfect for many use cases, but sometimes nothing beats good old text. But plain text logs have their own problems. As soon as you go plain text, you lose all of the structure. Text usually has no formatting, you can’t open details for the message, and you can’t filter text dynamically like you can a table view. But what if you could?
Toggle the “List” mode, and Pulse Pro will generate the formatted text based on your current filters. Change the filters, and it re-generates the text. I’ve done a ton of optimizations to make it as quick as possible. For example, I cache the strings generated for the individual messages and simply re-compose them later.
The text view itself is also pretty powerful. You can search, filter by line, show line numbers, and change some basic settings like font size. I’m also going the same minimap as in the console soon – more on it later.
You can also toggle “Show Responses” to see nicely formatted network responses inline with your logs. Unlike the traditional plain text logging system, you can make this choice on the display time instead of the time of logging, which is great.
Network Tab #
Pulse Pro has a dedicated network tab designed from scratch with its own columns and filters.
The most powerful filter is probably “General” where you can add as many custom filters as you’d like with an easy-to-use interface. You can filter by URL, host, method, request or response body or headers, and more.
Response Viewer #
Response viewer was also completely redesigned for Pulse Pro. It’s customizable, it shows line numbers, there is a new color theme that matches Xcode. Pulse Pro can also be used as a standalone JSON viewer. It has a ton of convenience features for manipulating JSON, such as collapsing and focusing on objects and arrays.
It also has jq integration. jq is a tool for processing JSON, applying the given filter. You can find some examples of what it can do at the jq website. It’s really-really powerful and Pulse Pro makes it super nice to use with side-by-side live results view, and nice output formatting.
When you scan through the logs, you sometimes find important messages you may want to get back to later. With pins, you can easily do that. Just click on the row number that you’d like to pin, and it will appear in the scroller. You can easily navigate back to this message by simply clicking on the mark in the scroller – just like breakpoints and errors in the Xcode scroller.
