Comments and Reviews
It's clearly designed for business use, though I'm hosting it for my own. Unfortunately, you can't start or stop a timer when offline. Nice that every time entry can contain markdown, and that it supports tags/labels, and has both a calendar view and list view.
It has downloads that are not for windows. It is unclear how someone who is not a programmer can use it. Most likely we need to wait for someone to offer it for free for non-programmers.
A good tech could figure this out pretty quickly but you're right - it's not plug n play in Windows although it is possible to get this running. You could run it in a VM (HyperV) or with Docker (which might be easier). Windows has HyperV included and Docker Desktop is free but it does require a bit of tech knowledge to get these set up.
Now that there is AI that can guide you through the setup process, this comment is not valid anymore.
My understanding is that there is a free version for self-hosted. . the rest is subscription.
You can use it for free, possiliby to add clients, projects, activities, generate reports for billing in various formats.
It's got a reactive web design that is mobile-friendly and desktop-friendly It was easy to tailor to operations management for commercial real estate. It can run on a very lightweight server infrastructure.
It's completely open source with a quite polished interface. There's enough options here to run a full company (variable rates per company). You still need invoicing software (say Invoice Ninja) to finish the billing, but Kimai can produce excellent billable hours reports.
Open software, web-hosted, could be used in a simply way.
