I occasionally do freelancing work and needed a simple way to build out a notional schedule based on estimated task length. There are many Gantt chart builders out there, but they typically require choosing start dates for each individual task. In addition, all the online builders make you enter the tasks in their own interface (clunky), cost money after some short trial (too much overhead), or don't offer an easy way to share the schedule with someone else.
Simple Scheduler asks for just a CSV of tasks, how long they'll take, who is going to work on each task, and any dependencies of each task. From there it spits out an SVG with each task scheduled based on the rules:
- Tasks are scheduled in the order they are in the CSV.
- A resource (person) can only perform one task at a time.
- A task's dependencies must be complete before it can begin.
- (by default) No work is done on weekends.
pip install projectschedulerCreate a CSV with your tasks in the format:
| Id | Task | Duration | Start | Resources | Dependency |
|---|---|---|---|---|---|
| 1 | Name of task 1 | 6 | 2022/11/30 | Joe | |
| 2 | Some other task | 3 | 2022/11/30 | Marc | 1 |
| 3 | Some other task 3 | 12 | 2022/11/30 | Alice | 2 |
Where duration is given in days. Multiple resources can be separated by a "/". (I.E, "Person1/Person2").
An example csv can found found in the repository. It builds into:

Python-gantt was the original inspiration for this project. I originally built the scheduler around it, but didn't like certain aspects of the API. This tool uses the rendering code from that project.
