Are there proxies which allow accessing ipfs links without having a local running node? I need to share a link with the general public.
There are http gateways that people who haven't installed ipfs can use. There's a list here:
There might be more, but that's as far as we got.
Just remember that if the IPFS object is a file (not a directory), and people access it in their browser, they will download it directly, and the file won't have any filename or extension. So it's best to add these files to a directory, and publish that directory's hash instead of the file's hash.
