# ngrok Alternatives: 13 Ways to Share Localhost, Compared > Free ngrok alternatives compared: which need no account, which keep your app off a public URL, and which skip the warning page. Every fact sourced. Source: https://layerv.ai/compare/ngrok-alternatives/ --- [← All Comparisons](https://layerv.ai/compare/) # ngrok alternatives for sharing localhost Thirteen tools that replace ngrok for sharing a local app, what each is best for, and what you give up. For a public URL with no account, use a Cloudflare quick tunnel. To show one person or a coding agent your app without a public URL or an account, use qURL™: each link works once and expires within 24 hours. Inside a tailnet, use Tailscale Serve. Keep ngrok for webhooks and request replay. Facts checked October 1, 2026, each value linked to its source. [Full dataset](https://layerv.ai/compare/localhost-tunnels/). ## Why people look for ngrok alternatives - An account and authtoken before the first URL. ngrok’s quickstart starts with signing up, and the agent will not start an endpoint without the token. - A warning page for your visitors. On the free plan, browser traffic sees ngrok’s ERR\_NGROK\_6024 page before it reaches your app. - Free-plan limits: 3 endpoints, 1 GB a month out, and 20,000 HTTP requests a month, on one assigned dev domain. - A public URL. Anyone who has the address can request your app unless you add a Traffic Policy, and the URL has no built-in expiry. ## The alternatives at a glance __ngrok alternatives: what each is best for, and account needed before the first URL, who can reach it, link expiry__ | Tool | Best for | Account needed before the first URL | Who can reach it | Link expiry | | ------------------------------------------------------------------------------------------------------------------------ | -------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | [qURL CLI](https://layerv.ai/compare/ngrok-alternatives/#alt-qurl) | Showing your app to a person or a coding agent with no account and no public URL | No. The first publish creates the device identity [our test](https://layerv.ai/research/qurl-behaviour) | No one until a link is opened;

Its web inspection interface on localhost:4040 shows every request and response and replays a request with one click, which none of the tools above match for webhook debugging. ## Frequently Asked Questions What is the best free ngrok alternative? It depends on who must reach the app. For a public URL with no account, a Cloudflare quick tunnel. For one person or agent, with no account and no public URL, qURL. For people on your tailnet, Tailscale Serve. For webhooks, any tool that gives a public URL; qURL is not built for them. Which ngrok alternatives work without an account? Cloudflare quick tunnels, localtunnel, Pinggy, Serveo, localhost.run, and bore.pub start without one, and so does the qURL CLI. Of these, qURL is the only one that does not give the app a public URL. Is there an ngrok alternative without a warning page? A one-time qURL link opens the app without a tunnel warning page. bore has none because it forwards raw TCP. Microsoft dev tunnels, zrok public shares from unverified free accounts, Pinggy and Serveo free tunnels, and localtunnel all show one. Can my coding agent share my app instead of me running ngrok? Yes. Point Claude Code, Cursor, or Windsurf at the qURL skill (https://layerv.ai/skills/qurl/SKILL.md) and ask it to share the app. It installs the CLI, publishes the app privately, and gives you an address to send. The agent applies the private access rules you choose. For named recipients, give it their email addresses so it can send invitations. Recipients verify their email in the browser and save a passkey; they never send you their email verification code. The agent checks policy support before sharing and keeps the app private if the deployment cannot support it. For one person right away, ask it for a one-time link instead. Codex starts with network access off, so save the skill file for it first. Which ngrok alternative is private by default? Microsoft dev tunnels are private until you allow anonymous access, but need a GitHub or Microsoft sign-in. Tailscale Serve is private to your tailnet. qURL gives the app no public URL and needs no account; without one you can keep up to 3 active resources, with links that last up to 24 hours. ## Related Resources [qURL vs ngrok →](https://layerv.ai/compare/qurl-vs-ngrok/) [Every localhost tunnel, compared →](https://layerv.ai/compare/localhost-tunnels/) [Guide: Share localhost without signing up →](https://layerv.ai/guides/share-localhost-without-signup/) [Vibe coding: share your app in one prompt →](https://layerv.ai/vibe-coding/) [Deploy a preview or share localhost? →](https://layerv.ai/compare/deploy-preview-vs-share-localhost/) [ngrok docs: Web inspection interface ↗](https://ngrok.com/docs/agent/web-inspection-interface/) [Open-source ngrok alternatives →](https://layerv.ai/compare/open-source-ngrok-alternatives/) [ngrok alternatives with authentication →](https://layerv.ai/compare/ngrok-alternatives-with-auth/) [Guide: switch from ngrok to qURL →](https://layerv.ai/guides/switch-from-ngrok/) [An ngrok alternative with no public URL ↗](https://qurl.link/private-ngrok-alternative) ## Built it with an agent?
