I need a remote desktop tool that allows unattended access and does not require a subscription.

Finding a reliable remote desktop tool that supports unattended access without locking features behind a paid subscription can be tricky, as mainstream options like TeamViewer or AnyDesk frequently flag personal use or push for commercial licenses.reddit.com

Here are the best open-source and genuinely free options available:

• RustDesk is an open-source, full-featured remote desktop client that supports unattended access by setting a permanent password and installing the application as a background service . You can use their public community servers for free without a subscription, or self-host your own rendezvous server for complete data privacy. Check out the code and downloads on the official RustDesk Website.rustdesk.com+3
• TightVNC is a classic, lightweight, and completely free open-source VNC-based tool. It is ideal for local networks or environments where you can set up port forwarding or a VPN. You install the server component on the host machine to allow continuous unattended access. Learn more and download it via TightVNC.
• UltraVNC is another robust, free, and open-source option specifically for Windows. It allows you to run the software as a system service for unattended reboots and access, and it supports file transfers and encryption plugins. Details can be found at UltraVNC.
• Parsec is technically tailored for low-latency game streaming and high-performance workflows, but its free tier allows you to connect to your own computers unattended if you log into the same account on both ends. It doesn't require a subscription for personal use. Explore features on Parsec.

If you want to narrow this down, let me know:

• What operating systems are you connecting between (e.g., Windows to Windows, Mac to Linux)?
• Will you be connecting locally over your home network or over the internet from outside locations?

Finding a reliable remote desktop tool that supports unattended access without forcing you into a recurring subscription can be tricky, as most commercial tools have tightened their free tiers. However, a few exceptional open-source and ecosystem-tied options fit your criteria perfectly.

• RustDesk — An open-source, fully free alternative to TeamViewer and AnyDesk. It supports cross-platform unattended access (Windows, macOS, Linux, Android) with no time limits, forced commercial pop-ups, or subscription fees. You can use their public community servers out-of-the-box or completely self-host your own sync/relay server for ultimate privacy and speed. Check it out at the RustDesk Official Website.reddit.com+2
• Chrome Remote Desktop — Completely free with no ads, caps, or paid tiers. It ties directly into your Google account and allows seamless, persistent unattended access to your machines as long as they are powered on and connected to the internet. It runs smoothly inside any browser or via native mobile apps without needing complex port-forwarding. You can set it up via the Chrome Remote Desktop Portal.
• TightVNC (or UltraVNC) + Tailscale — If you want a traditional, old-school local protocol approach with zero licensing baggage, you can install an open-source VNC server on the host machine and punch through your network securely using a free zero-config mesh VPN like Tailscale . It is completely free for personal and commercial use, has no subscriptions, and gives you raw, direct unattended control. You can grab the tool via TightVNC and pair it with Tailscale.reddit.com

To help narrow down the best fit, tell me:

• Are you connecting across the internet or just a local home network?
• What operating systems are you using on both the host and client ends (e.g., Windows to Windows, Mac to Windows)?

Yes. If your requirements are unattended access + no subscription, I’d look at these:

• rustdesk.com — probably the closest match. It’s open source, supports unattended access with a permanent password, and its RustDesk Server OSS is free to self-host with no license required.RustDesk+2
• Chrome Remote Desktop — free and relatively easy to set up for accessing your own computers remotely. It’s a good choice if you don't want to maintain your own server.RustDesk
• AnyDesk — free for personal/non-commercial use, but its professional use requires a paid license, and the paid plans are subscription-based.AnyDesk+1

My recommendation

For personal computers, I'd start with RustDesk. You can install it as a service, set a permanent password, and connect even when nobody is sitting at the remote computer.RustDesk

If you want zero server administration, Chrome Remote Desktop is simpler.

If you tell me whether the remote machine is Windows, Mac, or Linux, I can give you the exact setup steps for unattended access.

If you need unattended remote access and want to avoid a recurring subscription, these are the main options I’d consider:

Tool	Cost model	Unattended access	Best for
RustDesk	Free/open source; optional self-hosting	Yes (set a permanent password)	Best overall replacement for TeamViewer-style accessGitHub
HopToDesk	Free tier available	Yes	Easy cross-platform remote supportHopToDesk
Remio	Free	Yes	Simple personal/device access without accounts (per vendor claims)Remio
Chrome Remote Desktop	Free	Yes	Easiest setup for personal computers
Windows Remote Desktop (RDP)	Included with some Windows editions	Yes	Best if you only need Windows-to-Windows on a LAN/VPN

My picks

1. RustDesk — closest to a no-subscription TeamViewer alternative

• Works across Windows, macOS, Linux, iOS, and Android.
• Supports unattended access with a permanent password.
• Can use public servers or you can self-host your own relay/ID server for more control.GitHub
• Good choice for managing your own PCs or a small number of machines.

2. Chrome Remote Desktop — simplest

• Install the host component, enable remote access, set a PIN, and connect through your Google account.
• No paid plan required.
• Fewer IT features than RustDesk (less file-transfer/admin tooling).

3. HopToDesk — another free cross-platform option

• Supports unattended access and multiple operating systems.
• Open-source project with free personal/business availability stated by the vendor.HopToDesk

A few things to check before choosing:

• Business use: Some “free” remote tools restrict commercial use.
• Security: Use a long unique unattended-access password and enable 2FA where available.
• Headless machines/servers: RustDesk or RDP over a VPN are usually better fits than consumer tools.

If you tell me your setup (Windows/Mac/Linux, number of PCs, home vs business, and whether you need access over the internet or only on your network), I can narrow it down.

Yes. RustDesk is probably the best fit if you want unattended access without a recurring subscription.

What I'd choose

If your requirement is "I want to access my own PC/server remotely, unattended, indefinitely, and I don't want to pay a subscription", I'd choose RustDesk.

If you tell me whether the remote computer is Windows, Mac, or Linux, I can give you the simplest setup—including how to configure it to start automatically and allow unattended access.
