Questions owners ask
What is a free automation and internal tools tool a small business can actually run?
Appsmith is the highest measured score in this category right now (58). Internal apps on top of your database. Apache-2.0. The score only counts signals we could verify.
Does “no licence cost” mean the software is finished and supported?
No. It means you are not paying a vendor per seat or per contact for the right to use it. You still pay for a server, email delivery, or someone’s time. Archived and source-available projects are marked.
Are SeatLess apps placed first?
No. SeatLess apps are scored on the same rules and sorted by the measured score. They have no public repository, so GitHub health points are omitted and they do not float to the top.
