Sharing links to dapps
Overview
Once a dapp has been deployed to the mainnet, the canister serves the dapp's frontend via a URL. This URL can be shared with anyone, allowing them to view and interact with your dapp without you needing to configure domain names, DNS records, or other networking configurations.

When a canister is deployed to the mainnet (with a command such as dfx deploy --network ic), the canister's ID will be returned in the output. For example, when deploying a project with two canisters, the output will resemble:

Deployed canisters.
There are two canisters deployed, identified by their ids:
"poll_backend" canister created on network "ic" with canister id: "5o6tz-saaaa-aaaaa-qaacq-cai"
...
"poll_frontend" canister created on network "ic" with canister id: "5h5yf-eiaaa-aaaaa-qaada-cai"
You can use the following URL format to access your canister in the web browser:
https://<canister_id>.icp0.io
For example, to access a canister with a canister id of 5h5yf-eiaaa-aaaaa-qaada-cai:
https://5h5yf-eiaaa-aaaaa-qaada-cai.icp0.io
If you are sharing a link to a frontend (asset) canister, the frontend of the dapp will be displayed.
If you are sharing a link to a backend canisters, the CandidUI will be displayed.
