HTTPS Development Guides
Answers for the HTTPS local development searches developers actually use
Bore guides for local HTTPS development across frameworks and workflows, including localhost SSL, local APIs, loopback hostnames like l.bore.dk and local.bore.dk, webhooks, OAuth callbacks, secure cookies, mobile testing, and child subdomains.
These pages are built around real developer tasks, not just framework names. The library now covers local websites, local APIs, React, Next.js, Vite, Node.js, webhook testing, OAuth callbacks, secure cookies, mobile-device testing, Bore's child-host HTTPS routing, and Bore loopback hostnames for 127.0.0.1 development.

How to Put a React App on HTTPS in Development
Expose a React development app over HTTPS for secure browser APIs, embedded flows, mobile testing, and auth callbacks without setting up local certificate chains.
Workflow Guides
Use-case pages for webhooks, OAuth callbacks, secure cookies, and auth-heavy development flows.
Updated 2026-04-14
How to Test Webhooks on Localhost Over HTTPS
Receive webhooks on a local app over HTTPS without opening inbound firewall rules or keeping a manually configured reverse proxy around for development.

How to Use OAuth Callbacks With Localhost HTTPS
Handle OAuth and SSO callback flows in local development with a real HTTPS URL instead of trying to fit providers around plain localhost.
Updated 2026-04-14
How to Test Secure Cookies and Auth Flows in Local Development
Use a real HTTPS origin in development for secure cookies, browser auth behavior, embedded flows, and feature checks that do not behave the same way on plain HTTP localhost.
Bore-Specific Features
The parts of Bore that matter when one hostname is not enough.

Loopback Hostnames for Local Development on Bore
Use short Bore hostnames that resolve to 127.0.0.1 for local development, including l.bore.dk, local.bore.dk, localhost.bore.dk, and child hosts under each of them.

How to Split Frontend and API Origins in Local HTTPS Development
Keep the frontend and API on separate HTTPS origins in local development so you can test CORS, cookies, auth rules, and realistic host-based behavior.

HTTPS for Child Subdomains in Local Development
Bore lets you expose a local app on one HTTPS hostname and a second local service on a reserved child host like api.bo.bore.dk. That makes app and API origin splits much easier in development.
