Use local Holy CORS

JSON Form Data Raw

Response

Connect to Holy CORS on this computer?

Bug Days will contact the Holy CORS bridge at . When you send a request, Holy CORS connects to the service URL you enter.

Your browser may ask to “access other apps and services on this device.” Chrome grants that local-access permission to bugdays.com as a site, so its prompt cannot name Holy CORS or limit itself to this port. This page contacts the bridge address shown above; requests are not relayed through Bug Days servers.

Continue only if you started Holy CORS and want to use it. If the API allows browser requests, turn off Holy CORS and send directly.

Connect through Holy CORS

If an API does not allow browser requests, run Holy CORS on your computer:

# macOS (Homebrew)

brew trust bugdays-com/tap

brew install bugdays-com/tap/holy-cors

holy-cors

On Windows or Linux, download the Holy CORS binary and run it locally.

Or use Docker:

docker run --rm -p 127.0.0.1:2345:2345 ghcr.io/bugdays-com/holy-cors:latest

Leave the bridge URL at http://127.0.0.1:2345/. If your target API runs on your computer and Holy CORS runs in Docker, use host.docker.internal in the target URL instead of localhost. On Linux, add --add-host=host.docker.internal:host-gateway to the Docker command if needed.

Holy CORS runs on your computer. Requests are not sent to or stored by Bug Days.

When the target API already permits browser requests, you can leave Holy CORS off.
