ngrok vs. inlets: The Ultimate 2026 Comparison for DevOps and SREs

In the rapidly evolving landscape of cloud-native infrastructure, the need to securely expose local services, private Kubernetes clusters, and isolated development environments to the public internet has never been more critical. Whether you are testing webhooks, exposing a local database for debugging, or bridging a hybrid-cloud environment, tunneling tools are an absolute necessity.

For years, the default answer to this problem has been ngrok. However, as the demands of DevOps, Site Reliability Engineers (SREs), and Platform Engineers have matured, alternative solutions have risen to meet specialized needs. Chief among these is inlets, a self-hosted, cloud-native tunneling solution created by Alex Ellis, founder of OpenFaaS and a CNCF Ambassador.

In this 2026 guide, we compare ngrok and inlets across architecture, protocol support, Kubernetes integration, security, data sovereignty, and current pricing — verified directly against each vendor’s own documentation.

The Evolution of Secure Tunnels in 2026

The concept of a reverse-proxy tunnel is simple: a lightweight client runs on your private network, connects outbound to a public-facing server, and forwards incoming public traffic back to your isolated service. This bypasses the need for complex VPN setups, port forwarding, or firewall changes.

The use cases have expanded well beyond sharing a local React app or catching a Stripe webhook. Engineering teams now expose complex microservices, bridge internal CI/CD runners to GitHub or GitLab, and manage traffic for Kubernetes deployments spanning multiple clouds.

This shift highlights the philosophical divergence between the two tools. ngrok has positioned itself as a programmable network edge — an API gateway with global points of presence, traffic policy, and Kubernetes ingress built in. inlets was built specifically for the cloud-native ecosystem, prioritizing self-hosted data sovereignty, raw protocol flexibility, and integration with containerized environments.

Deep Dive: Understanding ngrok in 2026

ngrok remains one of the best-known secure tunneling tools, creating a public endpoint that maps directly to a locally running service.

From Localhost Tool to Programmable Network Edge

ngrok now markets itself as a secure ingress platform combining global load balancing, a reverse proxy, a firewall, an API gateway, and Kubernetes ingress. Recent product pushes include native Anthropic SDK support for its AI Gateway and tooling aimed specifically at connecting MCP servers to AI providers — a sign of where ngrok sees its growth market in 2026.

Key Features of ngrok

• Traffic Inspection and Replay — ngrok’s signature feature. A web-based or terminal inspector lets you see headers, payloads, and responses flowing through HTTP endpoints, and replay requests without re-triggering the originating service.
• Zero Trust Network Access — OAuth, SAML/OIDC, and IP allow-listing can all be enforced at the edge via ngrok’s Traffic Policy engine, so unauthenticated traffic never reaches your local machine.
• Global Edge Network — Traffic routes through ngrok’s own distributed points of presence, giving you low latency and an out-of-the-box DDoS firewall.
• ngrok Kubernetes Operator — The successor to ngrok’s older, now-archived Kubernetes Ingress Controller. The current Operator supports standard Kubernetes Ingress objects as well as the Gateway API (Gateway, HTTPRoute, and — more recently — TCPRoute and TLSRoute), and is available to all ngrok users at no additional charge beyond whatever resources it provisions.
• Developer Experience — A single command (ngrok http 8080) still gets you a public URL in seconds.

The Limitations for DevOps

ngrok’s free tier is genuinely restrictive in 2026: 1 GB of data transfer and 20,000 HTTP/S requests per month, capped at 3 online endpoints, with an interstitial warning page shown on free HTTP/S endpoints. It’s worth noting that several third-party blogs and “ngrok alternative” marketing sites currently claim ngrok’s free tier now enforces a hard 2-hour session timeout — this claim is not corroborated by ngrok’s own pricing or documentation pages, which describe usage-based limits (data transfer, requests, connections) but no session-duration cap. Treat that specific claim with skepticism until you can reproduce it yourself.

What is well-documented and consistently confirmed across independent sources is that ngrok still has no native UDP support as of 2026 — it handles HTTP, HTTPS, and TCP/TLS only. This rules it out for game servers, VoIP, and UDP-based IoT protocols like CoAP or DTLS. And because ngrok is a multi-tenant SaaS edge, all traffic passes through ngrok’s infrastructure before reaching your machine — a nonstarter for some data-residency and compliance requirements.

Deep Dive: Understanding inlets

Created by Alex Ellis, inlets was built to address exactly the pain points DevOps and Platform Engineers hit with SaaS tunnels like ngrok — namely, the inability to self-host, the lack of raw TCP/UDP support, and Kubernetes friction.

The Cloud-Native Tunnel

inlets creates a TLS-encrypted websocket tunnel between a client and a server, operating at Layer 4 (TCP) rather than terminating everything at Layer 7. This makes it protocol-agnostic: you can tunnel HTTP, but you can just as easily tunnel a database connection, SSH, or a Kubernetes API server.

Key Features of inlets

• Layer 4 (TCP) tunneling — inlets Pro tunnels databases (PostgreSQL, MySQL), SSH, RTSP, RDP, and Kubernetes API traffic, not just web traffic. Its own documentation is specific that UDP tunneling is currently supported for DNS traffic — this is narrower than a claim of general real-time/UDP streaming support, so don’t assume it covers arbitrary UDP workloads like game servers without checking the current docs for your use case.
• Total data sovereignty — inlets is fundamentally self-hosted. You run the exit server on infrastructure you control (a cheap DigitalOcean droplet, Hetzner box, AWS EC2 instance, etc.), or use Inlets Cloud’s managed HTTPS/SSH tunnel servers. Per inlets’ own site, your traffic never passes through a shared vendor edge, and your data is never used to train AI models or shared with third parties for that purpose.
• Kubernetes integration via inlets-operator — The operator watches for Service objects of type LoadBalancer in your cluster, provisions a small cloud VM, runs the inlets server there, and writes the public IP back onto the Service — mimicking what a managed cloud Kubernetes LoadBalancer does, but for bare-metal, home-lab, or air-gapped clusters. It’s commonly paired with ingress-nginx and cert-manager behind it so you can still get automatic Let’s Encrypt certificates via the standard HTTP-01/DNS-01 challenge flow — inlets provides the public IP; cert-manager and your ingress controller still do the certificate work.
• No bandwidth metering — inlets Pro and Uplink plans carry no per-request caps, throttling, or bandwidth billing; you’re limited only by what your own exit-server infrastructure can handle.

Head-to-Head Comparison: ngrok vs. inlets

1. Architecture and Traffic Routing

ngrok uses a multi-tenant SaaS edge. Your client connects outbound to ngrok’s cloud, and external requests hit ngrok’s global points of presence first before being routed to your machine. This buys you instant load balancing and DDoS protection, but means a third party sits in the traffic path.

inlets is self-hosted by design. You provision the exit server yourself (via inletsctl, the inlets-operator, or Inlets Cloud’s managed option), keeping the entire data plane under your own control.

2. Protocol Support

ngrok covers HTTP/HTTPS and TCP (TCP requires credit-card verification even on the free plan) and adds TLS endpoints on its Pay-as-you-go tier. It has no UDP support on any tier.

inlets operates natively at Layer 4, so HTTP, TCP, TLS-passthrough, and (for DNS specifically) UDP are all supported, without the HTTP-centric assumptions baked into ngrok’s architecture.

3. Kubernetes and Automation

ngrok’s Kubernetes Operator gives you ingress via standard Ingress objects or the Gateway API, offloading routing, auth, and observability to ngrok’s edge. It’s free to use, but ties your ingress configuration to the ngrok platform and its usage-based billing for the endpoints it creates.

inlets’ inlets-operator is arguably its signature feature for platform engineers: it gives bare-metal or home-lab Kubernetes clusters (K3s, kind, Minikube, on-prem) a genuine public LoadBalancer IP, the same experience you’d get on a managed cloud Kubernetes service, and it plays well with cert-manager for automatic TLS.

4. Bandwidth, Requests, and Pricing Structure (Verified July 2026)

ngrok’s current plan lineup is Free → Hobbyist → Pay-as-you-go → Enterprise (the older “Personal/Pro” naming has been retired):

Plan	Price	Online Endpoints	Data Transfer	HTTP/S Requests
Free	$0/mo ($5 one-time credit)	Up to 3	1 GB	20,000/mo
Hobbyist	$8/mo billed annually ($10/mo monthly)	Up to 3	5 GB included	100,000 included
Pay-as-you-go	$20/mo base + usage	Unlimited	5 GB included, then $0.10/GB	100,000 included, then $1/100k
Enterprise	Custom (contact sales)	Unlimited	Custom	Custom

Notable add-ons on Pay-as-you-go: SSO/RBAC is $10/user/month, and the full Identity & Access Governance suite (SCIM, domain controls, account-wide IP restrictions, audit logs) is $15/user/month regardless of user count. ngrok no longer publishes a flat per-seat Enterprise number; third-party pricing-intelligence firms (e.g., Vendr) report typical enterprise annual contracts in the $5,000–$75,000+ range, but this isn’t ngrok’s own published figure, so treat it as an estimate for budgeting purposes rather than a quote.

inlets’ pricing structure is unchanged in spirit from previous years and confirmed directly against inlets.dev:

Plan	Price	Tunnels Included	Commercial Use
inlets Personal	$25/mo	Up to 5	No (personal use only)
inlets Pro Commercial	$50/mo	Starts with 2 (+$25/mo each additional)	Yes
Inlets Uplink	$250/mo per cluster	Starts with 10 (+$25/mo each additional)	Yes, built for service providers

None of the inlets tiers meter bandwidth or requests — you pay per tunnel, not per gigabyte.

The verdict on cost: If you need an occasional throwaway URL for a webhook, ngrok’s free tier still works, with the caveat of the 1 GB/20k-request ceiling. For sustained traffic, database tunnels, or Kubernetes ingress on infrastructure you don’t want routed through a third party, inlets’ flat per-tunnel pricing is usually cheaper and more predictable, at the cost of having to run (or pay Inlets Cloud to run) your own exit server.

Use Cases: When to Choose Which?

Choose ngrok when:

• Quick developer demos — sharing a local app over a call with zero setup.
• Webhook debugging — ngrok’s traffic inspector and request replay remain best-in-class for integrating with Stripe, Twilio, or GitHub webhooks.
• Enterprise edge auth — gating an internal dashboard behind OAuth/SAML before traffic ever reaches your network, using ngrok’s Traffic Policy engine.
• AI/MCP gateway workflows — ngrok has invested specifically in connecting MCP servers to AI providers through its AI Gateway product.

Choose inlets when:

• Kubernetes ingress on private or bare-metal clusters — K3s on Raspberry Pis, on-prem OpenShift, or homelab clusters that need a real LoadBalancer IP.
• Strict data sovereignty or compliance requirements — where routing traffic through a shared third-party SaaS edge is a non-starter.
• Non-HTTP protocols — tunneling databases, SSH, RDP, or RTSP where ngrok’s HTTP-centric model doesn’t fit.
• Multi-tenant customer connectivity — Inlets Uplink specifically targets B2B vendors who need to reach into customer on-prem networks without deploying a full VPN stack per customer.

Setup and Developer Experience

ngrok remains the simpler on-ramp: install the binary, add your auth token, run one command. No cloud infrastructure knowledge required — the tradeoff is that a free-tier tunnel disappears the moment you close your laptop, and endpoint/domain persistence is a paid feature.

inlets asks a little more up front: inletsctl create uses your cloud provider’s API to provision a small exit-server VM and installs inlets on it, giving you back a connection string to use with the client. For Kubernetes specifically, inlets-operator automates this per-Service, and its Custom Resource Definitions fit naturally into GitOps workflows managed by ArgoCD or Flux.

Conclusion

The ngrok-vs-inlets decision is a choice of paradigms, and 2026’s numbers sharpen the contrast rather than blur it.

ngrok has doubled down on being a programmable, SaaS-hosted network edge — strong on traffic inspection, edge authentication, Kubernetes ingress via its Gateway API-aware Operator, and now AI/MCP gateway tooling — but its free tier is tight (1 GB/month, 20k requests), and it still has no UDP support on any plan.

inlets trades that SaaS convenience for self-hosted control: flat, predictable per-tunnel pricing, no bandwidth metering, genuine Layer 4 tunneling, and a Kubernetes operator purpose-built for giving bare-metal clusters a real public IP. Its UDP support is real but currently scoped to DNS, not a blanket answer for every UDP workload.

Choose based on whether you need a managed edge with polished observability (ngrok) or self-hosted, protocol-flexible infrastructure you fully control (inlets) — and verify pricing and feature details directly against each vendor’s site before committing, since both have changed their plan structures more than once in the past year.

Changelog

This article was rewritten from a submitted draft with the following fact-checks and updates, verified July 15, 2026:

1. ngrok plan names and pricing corrected. The draft referenced an outdated “Free / Personal / Pro / Enterprise” structure with Personal at $8/mo (10GB) and Pro at $20/mo (50GB). ngrok’s current published pricing (ngrok.com/pricing, ngrok.com/docs/pricing-limits) uses Free / Hobbyist / Pay-as-you-go / Enterprise, with Free capped at 1GB/20k requests, Hobbyist at $8–10/mo with 5GB/100k requests, and Pay-as-you-go at $20/mo base with 5GB included then metered overage.
2. Removed the unverified “$39/month per user” Enterprise figure. ngrok’s Enterprise tier is now quote-only; the $5,000–$75,000+ annual range is retained but attributed to third-party pricing-intelligence data (Vendr), not ngrok’s own pricing page.
3. Flagged the “2-hour free-tier session timeout” claim as unconfirmed. This claim appears on several ngrok-alternative marketing sites in 2026 but is not present in ngrok’s own pricing/limits documentation, which lists only usage-based caps.
4. Confirmed ngrok’s continued lack of UDP support across multiple independent 2026 sources — this claim from the original draft held up.
5. Renamed “ngrok Kubernetes Ingress Controller” to “ngrok Kubernetes Operator” — the original Ingress Controller repo is now archived in favor of the Operator, which additionally supports the Gateway API (including TCPRoute/TLSRoute).
6. Narrowed the inlets UDP claim. The draft implied inlets Pro broadly supports UDP for “real-time streaming protocols.” inlets’ own site currently scopes UDP tunneling specifically to DNS traffic — this has been corrected to avoid overstating support for use cases like game servers or VoIP.
7. Verified inlets Pro/Uplink pricing exactly against inlets.dev/pricing: Personal $25/mo (5 tunnels), Commercial $50/mo (2 tunnels + $25/mo each additional), Uplink $250/mo per cluster (10 tunnels + $25/mo each additional). The original draft’s figures were accurate and are retained.
8. Clarified the cert-manager/Let’s Encrypt integration claim. inlets-operator provisions the public IP/exit server; certificate issuance itself is still handled by cert-manager and an ingress controller (e.g., ingress-nginx) running behind it, not by inlets directly.
9. Removed unverifiable SEO metadata and title-tag artifacts from the original draft.
