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

Finding a completely free, non-subscription remote desktop tool that reliably supports unattended access can be tricky, especially since major commercial players (like TeamViewer and AnyDesk) aggressively flag free users for suspected commercial use or push paid plans.

The best options available that fit your requirements—broken down by whether you want an out-of-the-box cloud tool or a self-hosted solution—include:

• • The Details: A fully open-source (AGPLv3) remote desktop software designed as a direct alternative to TeamViewer. It natively supports unattended access by letting you set a permanent password on the host machine.
  • Subscription Status: 100% free with no hidden fees, time limits, or nag screens. You can use their public rendezvous servers out of the box, or—for ultimate privacy and zero reliance on third parties—you can host your own sync/relay server for free on a cheap VPS or local hardware.
• Chrome Remote Desktop
  • The Details: Google's official, browser-based remote access tool. It runs through the Google Chrome browser or a lightweight native app, supporting Windows, Mac, and Linux.
  • Subscription Status: Genuinely free with no paid tiers, ads, or upsells.
  • Unattended Access: Excellent for personal/internal use. By logging into the same Google account on both ends, you can configure a permanent PIN on the host machine for seamless, password-protected unattended access anytime.
• Iperius Remote Desktop
  • The Details: A high-performance remote control and support software.
  • Subscription Status: Offers a functional free tier that doesn't require a registration or subscription for basic use.
  • Unattended Access: Can be installed as a Windows service for unattended access, allowing you to assign a custom permanent password to log in whenever needed. (Note: Free tier has minor connection limitations concurrent-wise, but no forced subscription).

To help narrow down the best fit, tell me:

• What operating systems are you connecting from and to (e.g., Windows to Windows, Mac to PC)?
• Do you have the ability to self-host a small server (like RustDesk's relay), or do you need something that just works via the cloud?

Yes. I found several good options that meet unattended access + no required subscription:

🥇 My pick: HopToDesk

HopToDesk is probably the closest match to what you're asking for. Its client is free for personal and commercial use, with no session-length or session-count limits. It explicitly supports unattended access.

On Windows, installing it as a service means you can connect after a reboot and even before anyone logs into Windows—which is important for genuinely unattended machines.

🥈 DWService

DWService is also free and open source. You install its Agent on the remote machine, then access it through a web browser. Its documentation specifically supports unattended access.

This is particularly nice if you don't want to install a full remote-desktop client on the computer you're connecting from.

🥉 RustDesk

RustDesk is my choice if you care most about open source and self-hosting. Its open-source server can be self-hosted for free, with no license required.

The tradeoff is that self-hosting RustDesk requires more setup than HopToDesk or DWService.

Bottom line: For one or a handful of personal PCs, I'd start with HopToDesk. If you want the simplest browser-based solution, use DWService. If you want to own/control the entire infrastructure, use RustDesk.

If you tell me whether the remote computers are Windows, Mac, or Linux, I can also compare these specifically for reboots, Windows login-screen access, file transfer, Wake-on-LAN, and security.

If you need reliable unattended access without dealing with recurring subscription fees or annoying commercial-use pop-ups (like the ones that plague TeamViewer or AnyDesk), you have a few genuinely free options depending on your setup.

• Chrome Remote Desktop — Genuinely 100% free with no paid tiers, time limits, or subscription prompts. It links directly to your Google account, allowing you to set up a permanent PIN for seamless unattended access to your own computers or machines you manage.
• RustDesk — An open-source, highly secure alternative that acts like TeamViewer without the surveillance or subscription fees. You can use their public free rendezvous servers out of the box, or completely self-host your own server for total data privacy. By setting a permanent password and configuring it to run as a service, it handles unattended access smoothly.
• Zoho Assist — Offers a generous free tier that includes unattended remote support features for a small number of devices (up to 5 unattended computers) if you need a lightweight web-based tool for personal or small-scale maintenance.
• Built-in OS Tools (RDP / VNC) — If both machines are on the same local network (or behind a secure VPN like Tailscale), Windows Remote Desktop (Pro editions) or an open-source VNC server like UltraVNC provides completely free, unlimited, native unattended control with zero third-party subscription risks.

To help narrow down the best fit, tell me:

• Are you connecting across the internet or strictly locally on your home network?
• What operating systems are involved (e.g., Windows to Windows, Mac to PC)?

Yes. RustDesk is probably the best fit if your requirements are:

• Unattended access — connect to a computer even when nobody is sitting at it.
• No subscription — the open-source client and RustDesk Server OSS are free.
• Cross-platform — Windows, macOS, Linux, Android, and iOS.
• Permanent password/unattended access on desktop hosts.
• You can either use RustDesk's infrastructure or self-host the server if you want maximum control.

Other good option: Chrome Remote Desktop

If you don't want to bother with self-hosting, Chrome Remote Desktop is much simpler and free. It supports setting up a computer for access whenever you're away, including unattended access.

My recommendation

If this is for your own PCs: I'd choose Chrome Remote Desktop for simplicity.

If you want something more like TeamViewer/AnyDesk but genuinely free and without a subscription: I'd choose RustDesk. Its free OSS server is explicitly intended for individuals and teams, while the paid Pro server adds things like centralized management, 2FA, and device administration.

If you tell me Windows/Mac/Linux on the computer you're connecting to, I can give you the simplest setup for unattended access.

Finding a remote desktop tool that supports unattended access without locking features behind a paid subscription or commercial-use "nag screen" can be tough, but a few standout options fit the bill completely.

• RustDesk
  • What it is: An open-source, fast, and secure remote desktop tool written in Rust. It is widely considered the best free alternative to TeamViewer and AnyDesk.
  • Unattended Access: Fully supported. You can install it as a system service on Windows, macOS, or Linux so it stays active after reboots, and set a permanent password to log in whenever you need without someone on the other end.
  • Subscription: Completely free and open-source (AGPLv3). You can use their public community servers out-of-the-box, or optionally self-host your own rendezvous/relay server for total privacy and zero reliance on third parties.
• Chrome Remote Desktop
  • What it is: Google’s official, zero-fuss remote access tool that runs through your Google account and browser.
  • Unattended Access: Built natively for it. Once you link a host computer to your Google account and set a PIN, you can securely access that machine anytime it's turned on.
  • Subscription: 100% free with no premium tiers, ads, or hidden commercial limits. The main constraint is that it requires a Google account and an active internet connection.
• Microsoft Remote Desktop (Windows RDP)
  • What it is: The native, built-in remote protocol packaged directly into Windows Pro and Enterprise editions.
  • Unattended Access: Out-of-the-box support for local network (LAN) access without extra software. If accessing over the public internet, it requires pairing with a free zero-tier VPN like Tailscale or configuring port forwarding.
  • Subscription: Free, built right into the OS, and has no licensing restrictions or commercial checks.
• • What it is: A high-performance remote desktop tool relying on the NX protocol, known for exceptionally low latency and great handling of audio/video.
  • Unattended Access: Allows effortless connections to any remote machine once the service is running and configured to accept automatic connections.
  • Subscription: Free for personal use with no accounts or subscriptions required, though its license terms can be restrictive if you plan to use it in a commercial environment.

If you can tell me what operating systems you are connecting between (e.g., Windows to Windows, or Mac to Linux) and whether you need access over the local network or the internet , I can recommend the exact setup steps for the best fit.

Yes. I’d narrow it to these two:

🥇 My pick: HopToDesk

HopToDesk is free for personal and commercial use, with no session-length or session-count limits. It supports Windows, macOS, Linux, Android, iOS, and Raspberry Pi.

For unattended access, you enable a permanent password. On Windows, installing it as a background service lets you connect after reboots and even before someone logs into Windows.

🥈 DWService

DWService is also genuinely usable without a subscription. Its free tier has all features, with the main limitation being a 6 Mbps bandwidth cap. Unattended access is explicitly supported.

It's particularly nice if you want to access the remote machine through a web browser rather than installing a full client on the controlling computer.

What I'd choose

For a home PC/server that you want to access remotely whenever you need: HopToDesk.

For a low-bandwidth/simple browser-based solution: DWService.

If you want open-source + self-hosted so that no third-party company is involved in the connection infrastructure, I can also compare RustDesk vs HopToDesk—that's probably the most interesting option if "no subscription" is a hard requirement.

Yes. If unattended access + no subscription are the requirements, I’d narrow it to these:

My top picks

1. DWService — easiest

• Free plan includes all features; the main limitation is 6 Mbps bandwidth.
• Supports true unattended access, so nobody has to accept the connection.
• Runs as an installed background agent, making it suitable for a PC you want to access whenever it's on.
• Works across Windows, macOS and Linux.

2. RustDesk — my recommendation

• Open-source remote desktop software.
• You can use it without a subscription and, importantly, self-host the server for $0 using its free self-hosting plan.
• Supports unattended access.
• Better choice if you care about privacy/control and don't mind a little more setup.

3. Chrome Remote Desktop — simplest

• Google's service is free and designed for accessing your own computers remotely.
• Very easy to set up, particularly if you're already using a Google account.
• Less flexible than RustDesk/DWService if you're managing multiple machines.

What I'd choose

If this is one or a few personal Windows PCs, I'd use DWService for the easiest completely free solution.

If you want the most capable long-term solution without being dependent on a subscription service, I'd use RustDesk.

If you tell me what OS the computer you're connecting from and the computer you're connecting to are running (e.g. Windows 11 → Windows 11), I can recommend the best one and give you the setup steps.

Finding a reliable remote desktop tool that supports unattended access without forcing a recurring monthly subscription can be tricky, as many mainstream options have shifted to SaaS models. However, open-source and free-tier software provide great alternatives.

Here are the top options that fit your criteria:

• RustDesk
  • Overview: A fully open-source, modern alternative to TeamViewer and AnyDesk.
  • Unattended Access: Fully supported by setting up a permanent password or configuring the client for unattended access.
  • Pricing: Free and open-source for self-hosting. You can use their public free servers at no cost, or host your own signaling/relay server for complete control and privacy.
• TightVNC
  • Overview: A classic, lightweight Virtual Network Computing tool designed for local networks or direct IP connections.
  • Unattended Access: Runs as a system service on Windows, allowing you to connect at any time as long as the machine is powered on and reachable.
  • Pricing: Free and open-source (GPL) for both personal and commercial use.
• UltraVNC
  • Overview: Another powerful VNC-based solution packed with features like file transfer, chat, and secure encryption plugins.
  • Unattended Access: Can be installed as a Windows service for continuous background access.
  • Pricing: Completely free and open-source.
• MeshCentral
  • Overview: A comprehensive, self-hosted web-based remote management tool. It lets you manage an entire fleet of computers via a browser dashboard.
  • Unattended Access: The lightweight Mesh agent installs on target computers for permanent, unattended management.
  • Pricing: Free and open-source when self-hosted on your own hardware or local server.

If you'd like, let me know:

• Are you connecting over the internet or strictly on a local network?
• What operating systems (Windows, macOS, Linux) do you need to control?

I can help you choose and configure the best option from this list.

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

🥇 My pick: DWService

DWService is free, supports unattended access, and can be accessed through a web browser. Its documentation explicitly supports unattended access, meaning nobody needs to approve the connection at the remote computer.

The free tier currently has a 6 Mbps bandwidth limit, but all features are available without subscribing; paying only increases bandwidth.

🥈 RustDesk — best if you want more control

RustDesk is open-source and supports self-hosting. Its self-hosted server has a $0/month free plan, so you can avoid a recurring SaaS subscription entirely.

I'd choose RustDesk if you're comfortable with a little more setup and want something closer to a free TeamViewer/AnyDesk replacement.

What I'd avoid

AnyDesk is free for personal use, but its current paid plans start at $28.90/month billed annually for the Solo plan, and business use requires licensing.

Bottom line:

• Easiest: DWService
• Best long-term/free-control option: RustDesk
• Simple home PC access: Chrome Remote Desktop

If you tell me whether the computers are Windows, Mac, or Linux (and whether this is personal or business use), I can recommend the best one and give you the exact setup steps.

For a remote desktop tool that supports unattended access and is genuinely free without a subscription , you have two standout options depending on whether you prefer a completely managed cloud tool or an open-source, self-hosted approach.

• RustDesk - Best Open-Source & Self-Hosted Option
  • What it is: A fully open-source remote desktop client that serves as a direct alternative to TeamViewer and AnyDesk.
  • Unattended Access: Fully supported. You can install it as a system service so it runs at boot and set a permanent password in the security settings instead of using the rotating one-time code.
  • Subscription / Cost: Completely free for the community/open-source version. You can use their public relay servers or easily self-host your own connection/relay server on a cheap VPS or local hardware for total privacy.
• Chrome Remote Desktop - Best Zero-Configuration Cloud Option
  • What it is: Google's proprietary, browser-based remote access tool.
  • Unattended Access: Fully supported. By configuring "My Computers" on the host machine and assigning a persistent PIN, you can log in whenever you want without anyone needing to accept the prompt on the other end.
  • Subscription / Cost: 100% free with no paid tiers, time limits, or annoying commercial-use nag screens. The major catch is that it requires both machines to be signed into a Google account and run through the Google ecosystem.

To help narrow down which one fits best, tell me:

• What operating systems are you connecting between (e.g., Windows to Windows, Mac to Linux)?
• Do you prefer a tool that runs through a browser/Google account , or are you open to installing a dedicated application?
