📝 About ngrok
ngrok answers one of development’s oldest annoyances: your local server works fine, but the outside world cannot reach it. Run ngrok next to your dev server and seconds later you have a public HTTPS URL routing straight to localhost — perfect for testing OAuth callbacks, demoing work-in-progress to clients, or building mobile apps against a laptop backend.
The request inspector is what elevates it beyond a simple pipe. Every request and response is captured for inspection and replay, and built-in webhook support verifies signatures from Stripe, GitHub, Slack, and other providers so integration debugging stops being guesswork.
In 2026 alternatives like Cloudflare Tunnel compete hard on price, and free-tier URL randomization keeps nudging hobbyists elsewhere. But for pure speed from zero to working public URL, ngrok remains the tool that defines the category it created.
