antoniovr<p>I don't know if you already know <a href="https://mastodon.social/tags/transitous" class="mention hashtag" rel="tag">#<span>transitous</span></a> but if you don't it is worth to have a look at it. It's some kind of routing system <a href="https://mastodon.social/tags/freesoftware" class="mention hashtag" rel="tag">#<span>freesoftware</span></a> based mainly on open protocols as well as some APIs. </p><p>It combines every kind of public transport to route, sometimes you need to check how to write start and destination, but it is anyway amazing. You can check it on <a href="https://transitous.org/" target="_blank" rel="nofollow noopener" translate="no"><span class="invisible">https://</span><span class="">transitous.org/</span><span class="invisible"></span></a> </p><p>Its library or API is also used by other apps I also use such as <a href="https://mastodon.social/tags/Ktrip" class="mention hashtag" rel="tag">#<span>Ktrip</span></a> and <a href="https://mastodon.social/tags/Kitinerary" class="mention hashtag" rel="tag">#<span>Kitinerary</span></a>, or others like GnomeMaps</p>
