Tiles.openrailwaymap.org is a tile server demo for OpenRailwayMap, likely a volunteer open-source project rather than a commercial service. That context matters because expectations for a hobby site are different from those for an online store or SaaS product. Still, even for a non-commercial project, the exposed .git directory is a significant oversight. It means anyone with a browser can access source files and potentially configuration details. The site also shows up on one email blacklist, which is odd for a server that doesn't handle email. On the positive side, the site has been around since 2021, uses modern encryption, and loads fast. But these security issues suggest the server isn't actively maintained. If you're looking for map tiles to use in a project, it's worth checking whether the maintainers have addressed these gaps. There are no tiles.openrailwaymap.org reviews or scam reports to go on, but the exposed files alone justify caution. A legitimate infrastructure project typically secures its configuration and responds to basic security warnings.
