Do SSL HTTPS requests on Localhost using a domain and SSL certificates pointing to your local environment.
https://<any subdomain>.backloop.dev/ → https://localhost/
Any subdomain of *.backloop.dev points to localhost!
Exception: backloop.dev, which points to a page where you can download the certificates.
backloop.dev solves mixed-content issues when developing a WebApp or Backend on local environement while accessing ressources on remote HTTPS sources.
The issue is often raised by the same-origin policy mechanism that restricts the loading of resources from another origin unless this can be allowed by sending correct Cross-Origin Resource Sharing (CORS) headers.
Which anyway will fall-back on the must-have “non-mixed-content” (No HTTP & HTTPS)
But making requests to HTTPS APIs from HTTP sites on localhost would not be possible without changing security options on your browser, which is why backloop.dev provides SSL certificates with a full loopback domain, to let anyone benefit from a signed certificate on localhost.
SSL Certificates are updated weekly.
From december 2024 the key is now delivered in two files to be concatenated. It seems it was found by a robot and revoked as publicly available.
