The app https://zlant.github.io/parking-lanes is a visualisation and editor for parking information.
Onstreet parking information: bit.ly/parkingosm (uMap)
The parking map visualizes both parking areas and parking along streets. This image (the legend) shows the colour coding of the various parking conditions. Please try to add condition information for the parking areas displayed in purple.
The map on parking.openstreetmap.de (toolserver) isn't available any longer. The alternative is the slow and broken personal server parking.crite.net. The tiles are no longer updated since the toolserver is no longer active. https://zlant.github.io/parking-lanes is a running viewer and editor.
