Example migrations from ngrok to InstaTunnel
These are the most common production-adjacent development workflows: webhooks, preview links, and OAuth callbacks.
React/Vite preview
instatunnel 5173 --subdomain qa-previewShare a stable HTTPS preview link with QA without deploying a staging build.
OAuth callback
instatunnel 3000 --subdomain oauth-devRegister https://oauth-dev.instatunnel.my/auth/callback in the provider dashboard.
Decision table
| Workflow need | InstaTunnel | Common alternative |
|---|---|---|
| Webhook URLs | Reserved subdomains keep provider dashboards stable across restarts. | Random URLs often require manual callback updates after each session. |
| Cost control | Free for basic use, Pro starts at $5 for heavier development workflows. | Higher monthly plans may be needed for comparable team workflows. |
| MCP support | Purpose-built MCP tunnel flow with v2 transport support. | Usually requires custom routing or separate infrastructure. |
Common questions
Is InstaTunnel a direct ngrok replacement?
For localhost HTTP tunnels, webhook testing, stable demo links, and MCP endpoint tunnels, InstaTunnel covers the common day-to-day workflows teams usually use ngrok for.
Can I keep the same URL between restarts?
Yes. Use a reserved subdomain so webhook providers and teammates keep using the same HTTPS endpoint while your local app changes.
What should I update when moving from ngrok?
Update provider callback URLs, webhook endpoints, OAuth redirect URLs, and any README or QA links that point to the old ngrok hostname.
