Self-hosted alternatives to TeamViewer — weighing data sovereignty
Cloud SaaS remote-control tools like TeamViewer and AnyDesk are popular because they install fast and connect from anywhere. But because screen, input, and files pass through the vendor's cloud, and licensing and cost stay tied to the vendor's policy, many organizations look for a self-hosted remote-control alternative instead. This article compares the two approaches on general, verifiable dimensions — where data lives, licensing, and cost structure — rather than a feature checklist.
What to compare — structure, not features
Most remote-control tools offer similar core features: view and control a screen, transfer files, record a session. What actually differs when you pick one is where the connection passes through, how licensing works, and how cost grows.
| Dimension | Cloud SaaS (typical) | Self-hosted alternative (NetServ) |
|---|---|---|
| Connection server | Cloud run by the vendor | Run by your organization (on-prem, internal server, or VPS) |
| Data sovereignty | Brokered through vendor infrastructure | Screen, input, files, and audit stay inside your boundary |
| Licensing | Vendor's proprietary SaaS subscription | Classic / WebRTC free; SDKs: ConnectKit free forever + tiers by scale |
| Cost structure | Typically recurring, per seat / user | By server scale (peers) or developer seat; your own infra cost is separate |
| NAT traversal | Handled by vendor infra (opaque) | Hole-punch P2P + automatic relay fallback (operationally verifiable) |
| End-to-end encryption | Varies by product | Classic (J-PAKE) and WebRTC (DTLS-SRTP) are both end-to-end |
Public detail on any specific competitor's internals or pricing is limited, so this table compares a "cloud-brokered commercial SaaS" as a general category against NetServ's actual approach. Check a specific vendor's own materials for their exact specifications.
What to check before moving to self-hosting
- Where must data stay? — do regulation or security requirements say screen, input, files, and recordings can't pass through an outside cloud?
- Can you carry the operational load? — do you have the infrastructure and staff to run the connection servers (coordinator, relay, gateway) yourself, or do you need a managed service?
- Scale — the license tier that fits your concurrent PCs / sessions (free up to 5 peers, through large Enterprise)
- Usage pattern — always-on monitoring of many PCs (Classic), easy external / helpdesk access (WebRTC), or consent-based vendor / MSP access (SupportReach)
Which NetServ product fits
🖥️ Classic
Always-on monitoring (MultiView) of many PCs on closed / internal networks. Installs on both ends, plus a web viewer. Free now.
🔌 WebRTC
The viewer connects from a browser only. A fit for helpdesk / external access needing accounts and roles. Free now.
🤝 SupportReach
Consent-based remote support / MSP. Full recording, tamper-evident audit, vendor PRA. Enterprise / MSP.
The licensing angle
Cloud SaaS is usually usable only under the vendor's proprietary license and terms, billed recurring per seat or user. A self-hosted alternative means installing the server software that brokers connections (ServerKit) on your own infrastructure; if you assemble it yourself as a developer, licensing is structured per SDK (ConnectKit free, SessionKit per developer seat, ServerKit by peer scale). With a finished app (Classic, WebRTC) you skip the assembly and start right away.
Five things to check before migrating
Checking these five things before moving from cloud SaaS to self-hosting cuts down on the details that are easy to miss during rollout.
- Map your existing workflow — list which features you actually use today (remote control, file transfer, recording, chat, etc.) and confirm the new tool covers the same ground.
- Network requirements — get the ports your connection server needs (e.g. WSS 443, a UDP relay port) into your firewall policy ahead of time.
- Account and org-structure migration — plan how users, roles, and groups move to the new console. WebRTC supports accounts, roles, group policy, and a company enrollment key.
- Run a pilot — switch over a subset of teams / PCs first, verify stability and usability, then roll out organization-wide.
- Time the legacy cutover — align your existing SaaS contract's end date with when the new tool is stable, to avoid paying for both at once.
Frequently asked questions
What actually changes when I move from TeamViewer / AnyDesk to a self-hosted alternative?
The biggest difference is who runs the connection server. Cloud SaaS brokers your session through the vendor's
servers; a self-hosted alternative lets your organization run the coordinator, relay, and gateway itself, so
screen, input, files, and audit records never leave your boundary. Core features (remote control, file
transfer, recording) usually overlap — the difference is where data lives and how licensing is structured.
Is a self-hosted alternative also end-to-end encrypted?
Yes. NetServ's Classic uses J-PAKE and WebRTC uses DTLS-SRTP to encrypt screen, input, and files end-to-end. The
session key is created only on the two ends, so the relay server can't see the content whether it's
self-hosted or not.
Can I start for free?
Both Classic and WebRTC offer every feature free right now. Building it yourself with the SDKs, ConnectKit is
free forever and ServerKit is free up to 5 peers.
Is there something like the PRA (privileged remote access) feature of cloud SaaS, for MSPs and
vendors?
Yes. SupportReach provides consent-based (attended) remote support with scoped, time-boxed vendor access (PRA),
full session recording, and a tamper-evident audit log — self-hosted and end-to-end encrypted.
