✦Compare · Remio vs NoMachine

NX protocol vs WebRTC, side by side.

Bottom line — choose Remio if your clients are an iPad, iPhone, or Mac; pick NoMachine if you run a rack of Linux servers and thin clients. An honest comparison across latency, the NX protocol vs WebRTC, the account model, platform reach, enterprise features, and pricing. NoMachine has served Unix and Linux remote-desktop workloads for over two decades on the back of the NX protocol; Remio takes a different approach with WebRTC, hardware codecs, end-to-end encryption, and zero playout buffering. Different lineages, different audiences, different price points. Numbers are current as of May 2026.

✦The verdict

Which one should you pick?

Remio wins on latency, native mobile clients, visionOS, simpler setup, and price. NoMachine wins — and it is a real, hard-won win — on multi-user Linux terminal sessions and the enterprise stack. Here is the honest split.

Choose Remio if…

Your clients are an iPad, an iPhone, and a Mac.

You want about 8 ms of LAN P2P processing latency instead of 30–100 ms NX overhead, native mobile clients with Apple Pencil input and touch, a visionOS spatial window, and setup with no account and no relay-server licence to renew. The core remote desktop is free on every platform — 4K, monitor switching, and hardware H.265, with true 4:4:4 color live on NVIDIA PC → Mac, no per-device cap. Remio Pro, at $1.99 a month, is an optional add-on for extras like two-way file transfer and more virtual displays.

Stick with NoMachine if…

You run a rack of Linux servers and thin clients.

You need multi-user Linux terminal sessions, USB redirection, smart-card authentication, or the ARM Raspberry Pi thin-client deployments NX historically served. Two decades of polish on the Unix workstation side are real and matter for compliance-driven enterprise IT — and NoMachine's licence fee maps directly onto features that show up in an audit.

✦Detailed breakdown

Where each tool wins

Six categories, one paragraph each. The numbers in the table above are the headline; the paragraphs below are the why.

Protocol design — NX vs WebRTC

Bandwidth-thrifty X11 vs sub-frame interactivity

NoMachine's NX protocol was invented in 2003 to compress X11 over slow Unix workstation links and was last released as open source in 2009 (NX 3); current NoMachine ships a closed evolution that still carries the NX heritage of bandwidth-thrifty wide-area transport with lossless and lossy fallback modes. The design priority was always "make X11 usable over a 256 kbps line," and that origin story is visible in the 30–100 ms LAN latency the protocol still reports. NX is bandwidth-clever in ways WebRTC is not — it understands X11 primitives, deduplicates draw operations across frames, and shines on slow links — but the price is a software pipeline that buffers, retransmits, and waits for confirmations in ways a remote desktop targeting sub-frame interactivity cannot afford.

Remio runs on WebRTC M141 with hardware H.265 (H.264 fallback) over direct UDP, end-to-end encryption, and a zero-playout-buffer pipeline that targets sub-frame interactivity. The streaming philosophy is opposite to NX's: every frame is the latest screen state, lost packets are discarded rather than retransmitted, and the decoder is told to skip queued frames and render the newest one. Field trials enabled in the stack — ForcePlayoutDelay min/max 0, MinimumPlayoutDelay 0, Pacer-FastRetransmissions, Audio-Sync disabled — collectively strip every millisecond of buffering the stock build leaves in place. Different protocols, different decades, different priorities — and the numbers reflect it.

Linux strength and thin-client heritage

If you live on Linux, NoMachine is hard to beat

If you live on Linux, NoMachine is hard to beat. The NX protocol was born on Unix workstations, and NoMachine has spent two decades polishing the X11 and Wayland host experience — multi-user terminal sessions, virtual desktops you can disconnect from and reconnect to elsewhere, ARM binaries for Raspberry Pi thin clients, the entire shape of a Unix sysadmin's intuition. NoMachine's Terminal Server tier in particular maps cleanly onto the classic centralised-compute pattern: one beefy Linux host, dozens of cheap thin clients on the network, every user gets their own X session, sessions survive client disconnect. That is a deployment topology with a half-century of operational pedigree behind it, and NoMachine is one of the small handful of products that still ship a polished commercial implementation.

Remio now ships hosts for macOS, Windows, and Linux. The macOS host uses ScreenCaptureKit for capture, the Windows host uses DXGI Desktop Duplication, and the Linux host captures via X11; all three lean on platform-native hardware encoders where available (VideoToolbox on Apple, NVENC/AMF/Quick Sync on Windows, VAAPI on Linux with a software-encode fallback). The Linux host ships as a portable AppImage or a .deb package, and Wayland capture is on the roadmap — X11 desktops are supported today. What it does not do is multi-user terminal sessions: each Remio host is a single-user remote-control session, not a session broker serving many concurrent logins. For a Linux-first organization built around thin clients fanning out to a shared terminal server, NoMachine's Terminal Server tier is still the natural choice; for controlling one Linux machine from a phone, tablet, or another computer, Remio is now a real contender.

Cross-platform reach

Raspberry Pi thin clients vs iPad, Pencil, and Vision Pro

Both apps cover macOS, Windows, iOS, iPadOS, and Android. NoMachine adds Linux as a first-class host and client and ARM Raspberry Pi binaries for thin clients. Remio adds visionOS for Apple Vision Pro, ships iOS as a fully native SwiftUI app with Apple Pencil input (point, tap, and scroll) forwarded to the host, and treats touch and trackpad gestures on iPad as central rather than retrofitted. The iPad client supports Magic Keyboard and Universal Control-style cursor handoff between iPad and host — solid for navigating and clicking around a host desktop, useful enough that designers and illustrators use it to reach Procreate, Photoshop, or any desktop tool from the couch, though it's not a substitute for a pressure-sensitive drawing tablet.

NoMachine's mobile clients exist and are competent, but they were designed as remote-access utilities for an enterprise audience rather than as primary input devices. Touch is basic, and there is no visionOS spatial window for Mac mirroring. If your clients are a fleet of Raspberry Pis fanning into a Linux terminal server, NoMachine. If your clients are an iPhone, an iPad with Apple Pencil, a Vision Pro, and a Mac, Remio.

Enterprise features — USB, smart cards, multi-user

The enterprise stack NoMachine has built for decades

NoMachine's paid tiers ship the enterprise stack the open-source world has historically struggled with: USB redirection for printers, scanners, mass storage, and specialty hardware that lets a remote session use a locally-plugged device as if it were attached to the host; smart-card authentication for regulated industries that require physical-token login; multi-user terminal sessions where one host serves many simultaneous remote desktops; SSO and audit logs at the Enterprise tier. These are not minor checkbox features — each represents serious engineering against platform-specific kernel drivers, PKCS#11 stacks, session-management protocols, and audit pipelines that downstream compliance teams care about.

Remio is built around single-user interactive remote access with display streaming, keyboard, mouse, gamepad, clipboard, and file transfer. USB redirection, smart-card auth, and SSO are on the roadmap but not shipping. The product was designed for a different audience first: independent professionals, creative pros, gamers, developers who want to reach their own machine from another of their own devices. For a managed enterprise deployment in a regulated industry — healthcare, banking, government — NoMachine's licence fee maps directly onto features that show up in a compliance audit. For an independent professional or small team that doesn't have a compliance audit to pass, the missing pieces are unlikely to be missed.

WAN behaviour and setup

Automatic P2P + TURN vs port 4000 or a paid Cloud Server

To reach a NoMachine host across the public internet, you either forward port 4000/TCP on the host's router or pay for NoMachine Cloud Server to bridge the connection — both involve a setup step. Port forwarding requires router admin access, a fixed or dynamic-DNS-tracked public IP, and a willingness to expose port 4000 to the open internet. NoMachine Cloud Server avoids the port-forwarding step but adds a paid bridging server that lives in NoMachine's infrastructure and requires a NoMachine account to configure, with seat and bandwidth tiers driving the price.

Remio negotiates a direct peer-to-peer connection through STUN automatically. The connection server at relay.remio.net coordinates the initial handshake, the two peers exchange ICE candidates, and a direct UDP path is established between client and host with no port forwarding required. When symmetric NATs on both sides make P2P impossible, traffic falls back to a Cloudflare TURN relay that is built into the product and requires no account or configuration. The relay stays end-to-end encrypted: Cloudflare cannot inspect payload content. For a home or small-team user who just wants to reach their machine without learning what port forwarding is, Remio's WAN story is materially simpler.

Pricing tiers

Free core, not a ladder vs a four-tier commercial ladder

NoMachine Free is personal-only, capped at four desktop connections, and excludes the advanced features that make the paid product compelling. NoMachine Workstation is a perpetual licence at roughly $49.50 per seat that unlocks the full single-user feature set. NoMachine Cloud Server, which provides the WAN-bridging relay so you do not need to forward port 4000/TCP yourself, lists around $90–180 per year per server depending on user count. NoMachine Enterprise Desktop runs around $180 per year per server, and the Terminal Server tiers scale higher for multi-user deployments where one host fans out to many simultaneous remote desktops.

Remio's core remote desktop is free on every platform — no per-device cap, no resolution gate, no commercial-use detection. Remio Pro, at $1.99 a month, is one optional subscription for extras like two-way file transfer and extra virtual displays — not a ladder of tiers. The pricing model is structurally different rather than aggressively discounted: Remio operates without a centralised account database to support, without paid relay servers as a feature gate, and without enterprise sales motion baked into the product. If your needs map to the enterprise tiers — USB redirection, smart cards, multi-user terminal sessions, SSO — NoMachine's pricing reflects real engineering for real workloads and earns the cheque. If your needs map to "I want to reach my Mac from my iPad without paying anything and without filling in a signup form," the gap is large and one-directional.

✦Native, not a web wrapper

Every pixel, on real hardware.

Remio streams a full desktop to a native app on every device — SwiftUI on Apple, Jetpack Compose on Android, C++/WinRT on Windows. No NX buffering, no Chromium runtime in the rendering path: frames go from the hardware decoder to the screen the way the OS intends, which is where the ~8 ms LAN processing latency comes from.

Pair with a six-digit code. No account, no Cloud Server licence to renew.

✦Common questions

Common questions about NoMachine

The six questions people ask before they choose between NoMachine and Remio. Straight answers below.

Is Remio faster than NoMachine?

Yes, on every link type. Remio measures about 8 ms of processing (measured internally; the rest is your display's own 60 Hz refresh cadence) on a LAN peer-to-peer connection and stays in the low double digits within the same region even over a TURN-relayed WAN link. NoMachine's NX protocol typically reports 30–100 ms on a LAN and 100–300 ms over WAN — NX was historically engineered for bandwidth efficiency over a high-latency Unix-workstation link, not the sub-frame interactivity that WebRTC, hardware codecs, and zero playout buffering deliver.

Does Remio require an account like NoMachine Cloud Server does?

No. Remio uses a six-digit code to pair two devices and stores no user record at all. NoMachine works without an account for local LAN access — you connect by IP — but its NoMachine Cloud Server bridging feature, which lets you reach a host across the public internet without forwarding port 4000/TCP, requires a NoMachine account.

How does the NX protocol compare to Remio's WebRTC stack?

The NX protocol was created in 2003 to compress X11 traffic for the early commercial Unix remote-desktop market and was last released as open source in 2009 (NX 3); current NoMachine builds on a closed evolution of NX optimized for high-latency WAN with lossless and lossy fallback modes. Remio runs on WebRTC M141 with hardware H.265 (H.264 fallback) over direct UDP, end-to-end encryption, and zero playout buffering — a stack engineered for interactive sub-frame latency rather than bandwidth-thrifty wide-area X11 transport.

Can I use USB devices or smart-card authentication with Remio?

Not yet. NoMachine Enterprise tiers ship mature USB redirection (printers, mass storage, scanners) and smart-card authentication, which makes them strong choices for managed enterprise deployments and regulated industries. Remio currently focuses on display streaming, keyboard, mouse, gamepad, clipboard, and file transfer — USB redirection and smart-card auth are on the roadmap but not shipping today.

What platforms does Remio support compared to NoMachine?

Remio ships native apps for macOS, iOS, iPadOS, Android, Windows, and visionOS, plus a Linux host — so Remio now runs as a host on macOS, Windows, and Linux. NoMachine covers Windows, macOS, and Linux as hosts and adds Linux, Raspberry Pi, iOS, iPadOS, and Android as clients. NoMachine remains the stronger choice for multi-user Linux terminal sessions and Raspberry Pi thin-client deployments, where its NX heritage was originally proven.

How much does Remio cost compared to NoMachine?

Remio is free on every platform — no per-device cap, no resolution gate, no time limit — optional Remio Pro is $1.99 a month. NoMachine Free is personal-only with limited features. NoMachine Workstation runs about $49.50 perpetual per seat, NoMachine Cloud Server starts at roughly $90 per year, and NoMachine Enterprise Desktop runs about $180 per year per server, with Terminal Server tiers priced higher. If you want a complete remote desktop for free, Remio. If you need NoMachine's enterprise stack — multi-user terminal sessions, USB redirection, smart-card auth — the paid tiers earn their price.
