Localtonet as an ngrok Alternative in 2026: Pricing, UDP Support, and the Mobile Proxy Feature

For most of the last decade, “just use ngrok” was the default answer whenever a developer needed to expose a local server to the internet. It’s still a reasonable answer in 2026 — ngrok is mature, well-documented, and used by teams at Databricks, GitHub, and OpenAI. But its pricing has shifted toward production workloads, and one protocol gap (UDP) hasn’t closed. That’s opened room for smaller, more specialized tools.

Localtonet is one of them: a multi-protocol tunneling and proxy service built around a pay-as-you-go model, full UDP support, and an unusual built-in feature — turning an Android phone into a rotating mobile proxy. This piece looks at where Localtonet actually fits next to ngrok in 2026, what it gets right, and where ngrok still has the edge.

The Localhost Tunneling Landscape in 2026

Tunneling tools solve a specific problem: getting a public URL for something running on your machine, without touching your router’s NAT or your ISP’s CGNAT. Historically that meant HTTP — sharing a local React app, testing a Stripe webhook, debugging a REST API.

The workload mix has broadened. Real-time communication (WebRTC), game server hosting, and IoT device management all lean on UDP rather than TCP, and most of the established tunneling tools — ngrok included — were built HTTP/TCP-first and never added it. At the same time, distributed teams have made SSO, IP whitelisting, and custom domains table stakes rather than enterprise extras.

Where ngrok’s Pricing Actually Stands

ngrok restructured its plans, and the naming matters if you’re comparing tools: there is no “Personal” tier anymore. As of this writing, per ngrok’s own pricing page, the structure is:

• Free — $0. A $5 one-time usage credit, up to 3 online endpoints, 1GB data transfer, 20,000 HTTP requests/month, an interstitial warning page on HTTP(S) endpoints, and one auto-assigned dev domain. TCP endpoints require credit card verification.
• Hobbyist — $8/month billed annually, or $10/month billed monthly. $10 of included monthly usage, 5GB data transfer (more available against credit), 100,000 HTTP requests included, up to 3 online endpoints, no interstitial page, and access to ngrok-branded (but not custom) domains.
• Pay-as-you-go — $20/month base fee, which includes $20 of usage. This is ngrok’s plan for production traffic: unlimited online endpoints, unlimited team members (3 included, then $5/user), bring-your-own custom domains ($0.01 per active hour), and add-ons like SSO/RBAC ($10/user/month) and wildcard endpoints. Usage beyond the included credit — data transfer, requests, connections — is billed at metered rates ($0.10/GB for bandwidth, for example).
• Enterprise — custom pricing, SOC 2 Type II, HIPAA BAAs, SAML/SCIM.

Two things worth correcting against common claims elsewhere: ngrok’s free endpoints do not have a fixed session timeout — the docs state free endpoints “have no timeout” and can stay online indefinitely, though the monthly usage quotas (1GB transfer, 20k requests, etc.) still reset each billing cycle. And SSO isn’t something you get “with limits” on cheaper tiers — it’s a paid add-on exclusive to Pay-as-you-go, not available at all on Free or Hobbyist.

What hasn’t changed: ngrok’s documented endpoint types are HTTP, HTTPS, TCP, and TLS. There is still no UDP endpoint on any plan. That rules ngrok out, on its own, for Minecraft/Valheim/CS2-style game servers, WebRTC media, VoIP signaling, and UDP-based IoT protocols like CoAP.

Localtonet’s Pay-As-You-Go Model

Localtonet bills differently: instead of a subscription tier, you prepay a balance, and each tunnel draws roughly $2 per month while it’s actively running — prorated, so a tunnel running for two weeks costs about $1. Stop the tunnel and the balance stops moving. This is documented directly on Localtonet’s pricing page and corroborated by its own community support forum, where staff confirm the same ~$2/month-per-active-tunnel rate.

• Free — 1 tunnel (HTTP, TCP, or UDP), 1GB of bandwidth per month, and a 30-minute tunnel timeout — fine for quick tests, not for anything that needs to stay up.
• Pay-as-you-go — unlimited tunnels and unlimited bandwidth with no per-GB charge, no timeout, custom domains with automatic HTTPS via Let’s Encrypt, IP whitelisting, SSO, DNS management, and team accounts — all under the same ~$2/tunnel/month meter.

For a solo developer running one or two tunnels only while actively working, that’s meaningfully cheaper than ngrok’s Hobbyist tier, and it comes with UDP support ngrok doesn’t have at any price. For a team running many tunnels continuously in production, the math is closer to a wash — enough tunnels running around the clock adds up in the same way a subscription does.

Core Features Worth Knowing About

Native UDP tunnels. UDP is stateless, which makes it harder to tunnel reliably than TCP — there’s no built-in delivery confirmation to manage. Localtonet supports UDP, TCP, and mixed TCP/UDP tunnels natively, which is the whole reason it comes up in “ngrok alternative” searches at all. Practical uses: hosting a modded Minecraft or Valheim server without router port-forwarding or exposing a home IP, testing WebRTC signaling and media servers, and routing traffic for UDP-based IoT devices.

Mobile proxy via Android. This is the feature that sets Localtonet apart from most tunneling competitors. The Localtonet Android app links to your account via an AuthToken and turns the phone into an HTTP or SOCKS5 proxy endpoint that routes traffic through its cellular connection. IP rotation works by toggling airplane mode on and off, which forces the carrier to hand back a new IP on reconnect — Localtonet automates this with a configurable rotation interval or an on-demand reset link. On non-rooted phones, triggering that reset link works by prompting you to set the Localtonet app as your device’s default assistant app, which is what lets it flip airplane mode programmatically without root access. It’s a genuinely documented mechanism (verified against Localtonet’s own docs, its Google Play listing, and third-party write-ups), not a marketing exaggeration — useful for geo-testing, ad verification, and catching region-specific bugs, with the usual caveat that carrier-assigned IPs sit behind CGNAT and don’t map precisely to a single city or ISP subscriber.

SSO, included. Localtonet supports Google, GitHub, Microsoft, and GitLab as SSO providers (GitLab covers both gitlab.com and self-hosted instances), configured per-tunnel from the dashboard, bundled into the $2/tunnel paid plan with no separate per-seat charge. That’s a real contrast with ngrok, where SSO/RBAC is a $10/user/month add-on available only on Pay-as-you-go.

Webhook inspector, custom domains, file server tunnels. Localtonet captures, displays, and lets you replay incoming HTTP requests — useful for debugging Stripe, GitHub, or Slack webhooks. Worth noting this isn’t a point of differentiation from ngrok specifically: ngrok’s request inspector and replay tooling is free on every ngrok tier, including Free. Where Localtonet does differentiate is bundling custom domains with automatic Let’s Encrypt HTTPS into its one paid tier (ngrok gates custom domains behind Pay-as-you-go, metered at $0.01/active hour), and offering one-click file server tunnels for sharing a local directory.

Platform support. Windows (Microsoft Store or a self-contained binary, x64/x86/ARM64), macOS via Homebrew (Intel and Apple Silicon), Linux (a one-line install script, with ARM/ARM64 builds that run on Raspberry Pi), Android, and an official Docker image. There’s also a zero-install SSH mode — the dashboard generates a token-authenticated SSH command that works with the SSH client already built into Windows 10+, macOS, or Linux, no binary required. That mode is limited to TCP and HTTP; UDP tunnels and persistent background service mode need the full client.

Where ngrok Still Has the Edge

It’s worth being direct about this rather than treating the comparison as a rout. ngrok has SOC 2 Type II certification and will sign BAAs for HIPAA workloads on Enterprise contracts — Localtonet doesn’t publish equivalent compliance certifications, which matters if you’re evaluating either tool for a regulated environment. ngrok also has a Kubernetes operator, a traffic policy rules engine, and a decade of production deployment history at companies with real uptime requirements. Localtonet is a smaller, newer operation by comparison; its own community forum has relatively low post volume, and it’s worth confirming support responsiveness directly if you’re planning to depend on it for something business-critical, rather than assuming it matches ngrok’s support infrastructure.

If your workload is HTTP/TCP-only, doesn’t need UDP, and you value ngrok’s request inspection, Kubernetes integration, or compliance paperwork, ngrok’s Pay-as-you-go or Enterprise tiers remain a reasonable, well-supported choice despite the cost. Localtonet makes the most sense when UDP support, mobile proxy testing, or per-tunnel billing are the actual deciding factors — not simply because it’s cheaper on paper.

Practical Use Cases

The freelance web developer. Someone juggling 3–4 client projects a month, sharing local React/Node environments for live feedback calls. On ngrok Hobbyist that’s $8–10/month with a 5GB cap that heavy asset-loading demos can hit quickly. On Localtonet, billing only while tunnels are actually running during calls typically keeps the monthly cost in the $2–4 range, with unlimited bandwidth and no overage risk.

The indie game studio. A team testing custom UDP netcode for a multiplayer shooter with remote QA testers. ngrok is a non-starter here regardless of price, since it has no UDP endpoint on any tier. Localtonet’s native UDP tunnels let testers connect directly to a local game instance without router configuration.

The scraping/data pipeline operator. Someone whose scrapers get rate-limited by anti-bot systems. Localtonet’s mobile proxy feature, run on a spare Android device, routes traffic through real mobile carrier IPs and can trigger a fresh IP via the airplane-mode automation when a block is detected — without paying for a dedicated commercial mobile proxy network (though for large-scale, always-on proxy use, a purpose-built mobile proxy provider may end up more cost-predictable than per-tunnel billing).

Getting Started with Localtonet

1. Create an account at localtonet.com — the free tier is available indefinitely for testing.
2. Install a client. Windows (Microsoft Store or binary), macOS (Homebrew), Linux (install script, including Raspberry Pi/ARM builds), Android, or Docker — or skip installation entirely with the zero-install SSH option for TCP/HTTP tunnels.
3. Authenticate using the AuthToken from your dashboard.
4. Create a tunnel — choose HTTP, TCP, UDP, or a mixed TCP/UDP tunnel, point it at your local port (e.g., 127.0.0.1:8080), and start it.
5. Share the URL. Because the client makes outbound connections to Localtonet’s servers, it works behind NAT, CGNAT, and most corporate firewalls without router configuration.

The Bottom Line

ngrok remains the more mature, better-documented, and more compliance-ready option, and its request inspection and Kubernetes tooling are genuinely good. But its cheapest useful tier now runs $8–10/month with a 5GB cap, and it still has no UDP support on any plan — a real limitation for game servers, WebRTC, and UDP-based IoT work. Localtonet’s ~$2-per-active-tunnel pricing, native UDP support, and built-in mobile proxy feature make it a legitimate option specifically for those gaps, provided you’re comfortable with a smaller vendor that hasn’t published the compliance certifications ngrok has. Which one is the better cheap ngrok alternative depends less on price and more on whether UDP or mobile proxy testing is actually something you need.

Changelog

Corrections and additions made to the original draft, checked against primary sources:

• Removed leftover citation markers (e.g., [1.2.1], [1.3.3]) that referenced no visible source list — replaced with plain-prose sourcing throughout.
• Corrected ngrok’s tier name and structure. The original draft called ngrok’s entry paid tier “Personal” at a flat $10/month; ngrok no longer uses that name. Current tiers are Free, Hobbyist ($8/month billed annually or $10/month billed monthly), Pay-as-you-go ($20/month base fee for production traffic), and Enterprise. Source: ngrok.com/pricing and ngrok.com/docs/pricing-limits (fetched directly).
• Corrected the availability of custom domains and SSO on ngrok. The original comparison table implied both were broadly available with minor limits on lower tiers. In fact, custom domains and SSO/RBAC are both exclusive to the Pay-as-you-go plan and above — SSO is a $10/user/month add-on, and custom domains are metered at $0.01/active hour. Neither is available on Free or Hobbyist. Source: ngrok.com/pricing.
• Corrected/clarified ngrok’s free-tier session limits. Did not repeat the commonly circulated claim that ngrok’s free tier caps sessions at 2 hours — ngrok’s own documentation states free endpoints have no timeout and can run indefinitely, though monthly usage quotas (1GB transfer, 20k requests) still reset each cycle. Source: ngrok.com/docs/pricing-limits/free-plan-limits.
• Verified ngrok’s continued lack of UDP support directly against ngrok’s documented endpoint types (HTTP, HTTPS, TCP, TLS only, per the current pricing page’s protocol table).
• Verified Localtonet’s pricing model (~$2/tunnel/month, charged only while running; free tier of 1 tunnel, 1GB, 30-minute timeout) against Localtonet’s own pricing/blog pages and its community support forum, where staff independently confirm the same rate.
• Verified the mobile proxy / airplane-mode mechanism against Localtonet’s own documentation, blog post, and Google Play listing, including the non-root default-assistant workaround, rather than taking the original draft’s description at face value.
• Verified SSO providers (Google, GitHub, Microsoft, GitLab) and confirmed it’s bundled into Localtonet’s paid plan with no per-seat charge, contrasted against ngrok’s paid add-on.
• Added a balancing section (“Where ngrok Still Has the Edge”) covering ngrok’s SOC 2 Type II certification, HIPAA BAAs, Kubernetes operator, and longer production track record, plus a caveat about Localtonet’s smaller scale and comparatively low community forum activity — the original draft was one-sided in Localtonet’s favor without noting these trade-offs.
• Corrected platform support list for Localtonet to include Raspberry Pi/ARM builds and the zero-install SSH option’s actual limitation (TCP/HTTP only, not UDP), per Localtonet’s own documentation.
• Softened promotional framing and repeated hype phrasing (“Giant Killer,” “quietly dominating,” “completely redesigned the room”) throughout to match a plainer, trade-off-honest tone.
