Remote desktop tool with unattended access and no subscription

If you need a remote desktop tool for unattended access with no recurring subscription, I'd start with RustDesk or Chrome Remote Desktop. Both are good options for connecting to your own computer without someone sitting at the other end to approve each connection.

The key distinction is whether you want something that's completely free for personal use, open-source and self-hostable, or suitable for managing multiple computers.

Which one should you choose?

My recommendation: Try RustDesk first. Set a strong permanent password, install the service, and test reconnecting after a reboot. That ensures unattended access is actually working rather than relying on an application that only runs while someone is logged in.www.rustdesk.com+2

[Find my best option]

Yes. I found a few options that fit the unusually specific combination of unattended access + perpetual/one-time licensing.

1. Remote Utilities — my first choice

This is probably the closest match to what you're asking for. The vendor explicitly says “Buy it once, use it forever” and offers perpetual licenses with no recurring fees. It supports unattended access, relay connections, and even self-hosting your own server.www.remoteutilities.com

Current listed pricing starts at $99 per concurrent user for the Starter license, covering up to 20 controlled devices; the Plus tier is $249 and covers up to 50 devices.www.remoteutilities.com

A particularly nice feature if you're security-conscious: you can operate it entirely on your own network/infrastructure rather than depending on a vendor cloud.www.remoteutilities.com

I'd shortlist this if: you want something like TeamViewer/AnyDesk, but absolutely don't want another monthly bill.

2.TSplus Remote Access

TSplus offers perpetual licenses that never expire, with the first year of updates/support included. Its Remote Access product starts at $200/server one-time.tsplus.net

It's more oriented toward Windows servers, published applications, and remote desktops than being a lightweight TeamViewer replacement. TSplus also has a separate Remote Support product supporting attended and unattended control, but that product is subscription-priced.terminalserviceplus.com+1

I'd shortlist this if: you're managing Windows servers or want to publish applications/desktops to multiple users.

3. NoMachine

NoMachine is worth considering if remote-desktop performance is more important than having a conventional IT-support product. It explicitly supports unattended machines and doesn't distinguish between attended and unattended systems.www.nomachine.com

However, its current product lineup is complicated: some offerings are sold as subscriptions, including NoMachine Network, so I'd verify the exact edition/license before buying if “no recurring payment whatsoever” is a hard requirement.store.nomachine.com

What I'd avoid for your requirement

RealVNC Connect, TeamViewer, AnyDesk, Splashtop, Zoho Assist, etc. are generally subscription-oriented in their current commercial offerings. RealVNC, for example, explicitly describes its current device-access model as a subscription.www.realvnc.com

Bottom line: I'd start with Remote Utilities. It is unusually well aligned with “unattended remote access, pay once, keep using it.” Its perpetual license model is explicit rather than being an old product that happens to still have a perpetual version.

If you tell me how many computers you need to access (e.g. 5, 20, 100) and whether they're Windows/Mac/Linux, I can narrow this down to the cheapest 2–3 choices and compare their 5-year total cost.
