Traccar VS uMap

I use https://www.traccar.org/ 👍

I suggest traccar - https://www.traccar.org/, open source and it's already complete with a server and web interface. Now you need a gps device, one that's supported by traccar - https://www.traccar.org/devices/. I suggest getting one that's capable of making http requests because it's easier to integrate with traccar (for this you'll need a sim card with data), compared to going with an SMS route where you need a way for your server to receive SMS texts.

Traccar I'm not as familiar with but seems like a promising vehicular oriented one https://www.traccar.org/

Spotlight on Traccar, a self-hosted, open-source platform for GPS device tracking

Open source GPS tracking platform - Traccar (https://www.traccar.org/). I think picking a small B2B niche is the best way to become successful. You're not going to be super rich, but you can have a good stable lifestyle business.

Since your title contains "Real-time" I assume gagamit kayo ng GPS, then might I also suggest traccar, https://www.traccar.org/, complete with server and client, easily integrated with OpenStreetMap

Umap?

If that's not feasible and what you're doing isn't secret then perhaps something like uMap might work? This allows you to add overlays for the things you want to highlight and has a few different styles of basemap that tone down some of the clutter of the default "default" style. It also lets you pull (small amounts) of data into it via Overpass e.g. pre-mapped fishing spots or toilets. This can then be shared as a link or embedded in a site.

Having an OSM basemap overlaid with points is easily possible with uMap, for example https://umap.openstreetmap.fr/

Have you used the OpenStreetMap ecosystem of ID/JSOM or maybe uMap (https://wiki.openstreetmap.org/wiki/UMap) if you need the data separated from OSM?

Not an App, but did you take a look at https://wiki.openstreetmap.org/wiki/UMap? With it you can make personal maps with OSM base layers.

Depends what you mean by private. For something shareable on the web you might want to try one of the uMap instances, not sure if you can keep them secret though. If you decide to use them I recommend you log into an OSM account first as otherwise it is very easy to lose the edit link.

For public display one of the uMap instances is probably easiest. It should allow you to import your previously exported points and also allows line and area attributes. The share link included embed code for a website. The instance linked by /u/beardy64 is probably the most popular, but there are several listed at my previous link. I would recommend you log in before creating the maps as without a login you have to carefully keep track of you edit URL's if you might ever want to update things.

If someone is looking for an open-source webinterface for OpenStreetMap that offers a bit more eye candy, I recommend taking a look at Qwant Maps. Another useful OSM tool is uMap (source).
