You can actually view any public Telegram channel without requiring a Telegram account.
Typically, public channels on Telegram follow this pattern
t.me/<channel-name>. For example, t.me/jesstern will direct you to my public channel. However, you need to have a Telegram account to view the channel.
Public channels on Telegram can also be viewed without a Telegram account if you include a
/s/ before the channel name. The pattern is as follows
t.me/s/<channel-name>. For example, t.me/s/jesstern can be viewed directly in your web browser.
