Open Time Clock

Open Time Clock is a web-based timecard solution that gives its users some time tracking functionality and features for free. The solution is completely free for unlimited users and employees, which makes it a great choice for startups and small businesses.

The free version also includes multiple shift tracking, location permissions, and GPS tracking. It also offers PTO requests and an approval system at no cost.

You can also use it on your mobile devices for free, so you can always have access to the solution even when you are out of the office.

It should be noted that the free version doesn’t offer reports. It also doesn’t include webcam functionality which is appreciated by some businesses. Neither does it come with their 24-hour customer service line or their tech support.

We feel obliged to tell you that their “free tech support” isn’t really free as it includes a small fee. You might not mind it at the end, but it is the kind of “hidden fee” that reviewers should tell people about the moment we learn about them.

CKZ Time Clock

CKZ Time clock is an on-premise, open-source time tracking software used by businesses to track employees’ arrival and departure times.

You can get the solution for free for up to three users. Employees can punch cards, and the software will log the times and record them.

The free version free for up to three users offers useful features such as real-time employee monitoring, vacation time, payroll reporting, time and attendance tracking, holiday pay, and sick days.

As mentioned above, the solution offers all its features for free but limits users to three only, but you can add additional employees by upgrading to a premium plan. Premium plans also give you in-app security measures which are not enabled in the free version.

SwiftTime by Soniga

SwiftTime Clock by Soniga is a time tracking tool that offers the basics. It’s only suitable for those who know what they need out of the software and don’t care much about aesthetics or care at all about them.

SwiftTime is free for 15 users or less, and with the free version, they offer time tracking, punch-in, and punch-out capability, time-off requests, schedules, and vacations. The solution is smart enough to deny time-off requests that go over the limit.

SwiftTime works with any web browser, so you can use it whatever operating device you’re on (Mac, Windows, Android, and iOS).

SwiftTime’s features make it a good option for startups that want a tool that tracks work times has teamed with less than 15 people and works on mobile devices.


Hourglass is a Java-based open source time tracking solution that includes some project management features. The solution allows managers to create ‘nested projects,’ which is a useful feature for startups and small businesses with complex work hierarchies.

Managers can use it to track working hours and record new entries, and edit existing ones. Unfortunately, no task management is available, but users can add sub-projects which some use as a replacement for tasks.

Reporting is available for the free version, but you can’t export them, which is limiting.

Anuko Time Tracker

Anuko TimeTracker is a web-based time tracking software that comes with project management capabilities. The solution is user-friendly and suitable for businesses of all sizes.

Anuko can be used to track working hours, and the solution can track the time spent by employees on certain projects and store its records where you can easily access them from any device, at any time, and from anywhere in the world.

Anuko is a good option for startups because of its features and ease of use and its intuitive interface, reliability, and high-quality support.

The solution can be used from any device as long as it has an internet connection and a web browser that gives you access to the reports while you are out of the office. You can view these reports online or download them as spreadsheets to check them later. You also have the option of having them sent straight to your e-mail inbox.

TimeClock MTS

The free version comes loaded with useful features such as clock-in/clock-out functionality, fingerprint attendance tracking, time-off requests, and reporting. TimeClock MTS can also take pictures of your employees at work using their webcam if you want to (we highly recommend talking with your employers before activating this feature)

Setting the solution up is easy thanks to their Auto-setup, and the security measurements make you feel reassured and confident in the results you see.

The solution comes with project and task management capabilities to make managing your business a bit easier. It also offers some customization options so it can fit your workflow best.

The solution is not automated, though, and you need to set up your working hours and pause it manually when you are not working. When you are not working, the solution will count the time as ‘idle time.’

Rachota allows users to prioritize their tasks and will not allow you to start a low-priority task before finishing the most important tasks first. It also comes with private projects.

Rachota can also generate invoices and export them as Excel files (CSV) or HTML. One lacking feature is the ability to export the files in PDF, but Rachota could be a good fit with your startup if you can live with it.

As you can see, there is plenty of time tracking software open source, so you can customize them any way you want to get the best performance and results out of them.

Before you go, we need to talk for a minute about something essential.

One last thing

Despite what the news might have you believe, most people are actually good, honest, hardworking people. However, now and then, one must face a few of the other types, so you need to be aware and prepared.

You should know that any time tracking solution that uses the computer’s clock can be tricked by a dishonest person with good technical background and knowledge of what they can and can’t do.

You can easily prevent this by locking in their computer’s data and time settings so that no one can make any changes to the date and time without the admin password (which, of course, only you should have).

We hope this has been helpful. There are many other options to choose from, but we thought we would save you some time by offering the best options right away.
