✦TeamViewer alternative · free for everyone

Flagged for "commercial use"? The alternative that's free for everyone.

Q: Does Remio flag commercial use?

No. Remio has no commercial-use detection of any kind. Use it at work, on client machines, or across an office — no algorithm watches your usage patterns, and no session is ever shortened or blocked.

Q: Is Remio safe?

Yes. Sessions are end-to-end encrypted, with keys negotiated directly between your devices — a relay only ever forwards ciphertext. Because Remio has no accounts, there is also no central password database for an attacker to breach.

Remio does what you actually use TeamViewer for — unattended access, cross-platform control, screen sharing that just works — with no account and no commercial-use detection. Native apps, end-to-end encryption, ~8 ms of processing latency on LAN, paired with one six-digit code you can rotate anytime.

✦Why people switch

Why people look for a TeamViewer alternative

TeamViewer is a capable, two-decade-old product, and for enterprise IT it still earns its keep. The reasons people leave are specific and documented: the free tier's commercial-use detector, the price of escaping it, the mandatory account, and a security record that makes centralized vendors look like targets.

Commercial-use false positives

"Commercial use suspected" — and your session ends in 5 minutes

TeamViewer's free tier is licensed for personal use only, and an automated detector decides which side of the line you are on. Connect to too many machines, connect too often, or touch a host that looks like an office PC, and the warning appears — after which free sessions are cut to roughly five minutes, with forced timeouts between reconnects.

The detector produces false positives, and TeamViewer's own support flow acknowledges this: there is a reset form where flagged personal users can plead their case and wait for review. Helping a parent with their work laptop should not require an appeals process.

The price of the exit

Clearing the flag means a license — from $24.90 per month

Once flagged, the practical fix is a subscription. TeamViewer's entry plan, Remote Access, starts at $24.90 per month; Business is $50.90 per month; Premium starts at $112.90 per month — per seat, billed annually. For a freelancer who reaches two machines a few times a week, that is several hundred dollars a year for capability the hardware already has.

Mandatory account

An account is now required — even on the free tier

The current TeamViewer Remote client requires creating and signing in to a TeamViewer account before you can start sessions — free tier included. That is an email, a password, and a profile in a central database, plus device-trust verification emails when you sign in somewhere new. Every account database is a liability you carry for as long as you use the product: one more credential to manage, one more record an attacker would love to dump.

June 2024 · APT29

A state-backed breach of TeamViewer's corporate environment

In June 2024, TeamViewer disclosed that APT29 — the Russian state-backed group also linked to the SolarWinds campaign — had compromised its internal corporate IT environment via an employee account. To be precise and fair: TeamViewer stated that the corporate network is segmented from the product environment, and reported no evidence that the product network, connectivity platform, or customer data was touched.

The product was not breached. But the incident — the second nation-state intrusion TeamViewer has disclosed, after a 2016 incident attributed to Chinese state actors — illustrates the structural issue: a vendor that operates a central account database and relay network is a high-value target, forever. Architectures with no accounts and no relay decrypt path have less to steal.

✦The replacement checklist

What to look for in a replacement

Six tests, in descending order of how often their absence sends people back to square one. Apply them to any candidate — including Remio.

Truly free — no personal-only asterisk: "Free" should mean licensed free for any use, not free until an algorithm decides you look commercial. If the license has a personal-use clause, you have not replaced the problem — you have rescheduled it.
End-to-end encryption with no relay decrypt path: Session keys should be negotiated directly between your two devices, so any relay in the middle forwards ciphertext it cannot read. "Encrypted in transit" is weaker: it can mean the vendor's relay decrypts and re-encrypts, which makes the vendor part of your threat model.
No account required: Pairing should work without an email, a password, or a profile. No account means no credential database to breach, no password resets, and nothing to subpoena, leak, or phish.
Native apps — not Electron, not a web wrapper: A remote desktop client lives or dies on input latency and decode efficiency. Per-platform native apps use the system's hardware video decoder and input pipeline directly; Electron and browser-based clients pay a runtime tax on every frame and every keystroke.
Measurable latency: The vendor should publish numbers — milliseconds on LAN, milliseconds on WAN, measured when — that you can verify on your own network in an afternoon. "Blazing fast" is not a number.
Cross-platform, both directions: Mixed households and mixed offices are the norm. The tool should host on macOS, Windows, and Linux and connect from phones, tablets, and desktops on every OS you own — otherwise you end up running two tools to cover one fleet.

✦Meet Remio

The free, no-account alternative.

Remio passes the checklist above by construction, not by promise. Every app is built with the platform's first-party toolkit — SwiftUI on Apple, Jetpack Compose on Android, C++/WinRT on Windows. No Chromium runtime, no web view in the rendering path: frames go from the hardware decoder to the screen the way the OS intends.

Completely free, every feature — with no commercial-use detector deciding you owe money.

✦The factual record

What Remio is built with, what it costs, what it measures

No marketing adjectives — just the design decisions and the measured numbers behind them.

100% native apps

SwiftUI, Jetpack Compose, C++/WinRT — no Electron anywhere

Every Remio app is built with the platform's first-party toolkit: SwiftUI on iOS, iPadOS, macOS, and visionOS; Jetpack Compose on Android; C++/WinRT on Windows. There is no Chromium runtime, no JavaScript bridge, and no web view in the rendering path — frames go from the hardware decoder to the screen the way the OS intends.

Completely free

Every feature included — no commercial-use detection

Remio is completely free, and every feature ships in the one build everyone gets: 4K streaming, display switching with a dedicated virtual display, unattended access, Wake-on-LAN, end-to-end encryption. There is no commercial-use detector, no session timer, and no feature held behind a higher tier. Use it at home, at work, or for clients — the license does not distinguish.

No account · PIN pairing

A six-digit code — rotate it anytime

Pairing two devices takes a six-digit code shown on the host. Type it into the client, and the devices exchange keys and remember each other. No email, no password, no profile, no central user database. There is nothing to sign up for and nothing to breach.

End-to-end encryption

End-to-end encrypted — keys never leave your devices

Sessions are encrypted end-to-end, with keys negotiated directly between your devices. Keys never leave the endpoints, so when a relay is needed to cross a strict NAT, it forwards ciphertext it cannot decrypt. The full design is documented in the security whitepaper.

Measured, not marketed

About 8 ms of processing latency on LAN — measured internally

On the same network, the processing pipeline — capture, hardware encode, the LAN hop, hardware decode — costs about 8 ms; the rest is your display's own 60 Hz refresh cadence, so your input lands before the next frame draws. Across the internet within the same region, low double-digit milliseconds. Both figures are Remio's own measurements, and the methodology is published on the benchmarks page so you can reproduce them on your own hardware.

Quality & platforms

4K at up to 60 FPS, display switching included

Streams run a buttery 4K at up to 60 FPS on hardware H.265, with H.264 fallback — and display switching, with a dedicated virtual display sized to your device, is fully supported. Hosts run on macOS 15+ and Windows 10 (build 19041+)/11; clients run on iOS/iPadOS 18+, macOS 15+, Android 12+, Windows 10/11; on Apple Vision Pro, the iPad app runs today (native visionOS client in development).

✦The honest field guide

Other alternatives worth considering

Remio is not the only credible exit. Three others deserve a look, with one honest sentence each on when you should pick them instead.

RustDesk · open-source and free: RustDesk is open-source, genuinely free, and self-hostable — but taking full control means running your own relay and ID server, which turns a remote desktop app into a small ops project. Pick RustDesk over Remio if you want source code you can audit and infrastructure that is entirely yours. See Remio vs RustDesk for the full breakdown.
Chrome Remote Desktop · free and simple: Chrome Remote Desktop is free and takes two minutes to set up, but it requires a Google account, typically runs at 50 ms+ latency, and has no real multi-monitor support or remote audio. Pick it over Remio if you live in the Google ecosystem and only need occasional, undemanding access to a single machine. See Remio vs Chrome Remote Desktop.
Windows Quick Assist / Apple Screen Sharing · built in: Both ship with the OS, cost nothing, and require no install — but Quick Assist is attended-only (someone must accept on the remote end every time), and Apple Screen Sharing is Mac-to-Mac only. Pick them over Remio for one-off help sessions inside a single-OS household where installing anything is a non-starter. See Remio vs Apple Screen Sharing.

✦The five-minute switch

How to switch in 5 minutes

No migration tools, no exported address books, no account to create. Two installs, one PIN, and an optional toggle for unattended access.

Install the host

On the machine you want to reach — macOS 15+ or Windows 10 (build 19041+)/11 — grab the host from the download page, launch it, and grant the screen-capture permission once. It then waits in the menu bar or system tray.

Install the client

On the device you connect from — iPhone or iPad (iOS/iPadOS 18+), another Mac (macOS 15+), Android (10+), a Windows 10/11 PC, or Apple Vision Pro via the iPad app — install the Remio client from the same download page.

Pair with the code

The host displays a six-digit code. Type it into the client, and the devices exchange keys directly and remember each other. Reconnections are instant, no re-entry required.

Optional: unattended

Flip on unattended access in the host settings to connect without anyone at the remote end, and enable Wake-on-LAN to wake a sleeping machine first. The full walkthrough is in the getting-started guide.

✦Common questions

Common questions about switching from TeamViewer

The five questions people ask before they replace TeamViewer. Straight answers below.

Is Remio really free?

Yes. Every feature on every platform is free — 4K streaming at up to 60 FPS, display switching with a dedicated virtual display, unattended access, Wake-on-LAN, end-to-end encryption, all of it. There is no paid tier, no feature gate, and no commercial-use detection deciding you owe money.

Does Remio flag commercial use?

No. Remio has no commercial-use detection of any kind. Use it at work, on client machines, or across an office — no algorithm watches your usage patterns, and no session is ever shortened or blocked.

Is Remio safe?

Yes. Sessions are end-to-end encrypted, with keys negotiated directly between your devices — a relay only ever forwards ciphertext. Because Remio has no accounts, there is also no central password database for an attacker to breach.

Can I use unattended access?

Yes, and it is free. Enable unattended access on the host once and you can connect any time without someone clicking Accept on the remote end. Pair it with Wake-on-LAN to wake a sleeping machine before you connect.

Does it work Mac to Windows / Windows to Mac?

Yes, both directions. Hosts run on macOS 15+ and Windows 10 (build 19041+) or 11, and any client — iOS/iPadOS 18+, macOS 15+, Android 12+, Windows 10/11 — can connect to either host platform.

Leave the commercial-use detector behind.

Install the host, install the client, type a six-digit code once. No account, no usage scoring, no five-minute timer — end-to-end encrypted, native on every platform, and free with every feature included.
