Self-hosted alternatives to TeamViewer
It aggressively flags personal use as commercial and cuts sessions off mid-support call.
Below are 10 open-source projects that cover the same ground, each scored 0–100 on how actively it is actually maintained — commit volume, release cadence and recent trend. 7 of the 10 are currently rated healthy or better. Ordering reflects that score, not sponsorship.

How these were picked
Every project listed here is open source and can run entirely on hardware you control. We start from the categories that match TeamViewer's job — Remote Access — then rank by health score so that a popular-but-abandoned project never appears above a smaller one that is actively shipping. The scoring method is documented in full.
The scores are recomputed from repository data on every rebuild, so this page reflects the state of these projects as of 1 Oct 2026 — not the day it was written.
Firezone
Secure remote access gateway that supports the WireGuard protocol. It offers a Web GUI, 1-line install script, multi-factor auth (MFA), and SSO.
Best fit: Administrators seeking a manageable WireGuard deployment with built-in identity provider integration and a graphical user interface.
Worth knowing: You will need to evaluate how its access control model and authentication dependencies fit your existing security infrastructure.
Puter
Web-based operating system designed to be feature-rich, exceptionally fast, and highly extensible.
Best fit: It is well-suited for developers and administrators looking to host a centralised web desktop for file organisation and remote access.
Worth knowing: The copyleft AGPL-3.0 licence requires you to make your source code available if you modify and network-host the application, which may not suit commercial deployments. Additionally, web-based operating systems can introduce significant security and sandboxing considerations.
Pangolin
Identity-aware tunneled reverse proxy with dashboard UI, access control, and WireGuard-based tunnels (alternative to Cloudflare Tunnel, Tailscale).
Best fit: Self-hosters who want to expose private internal services securely without opening inbound firewall ports, while retaining control over identity management and routing.
Worth knowing: It overlaps heavily with well-established alternatives, meaning you should evaluate whether its specific dashboard and WireGuard approach suits your existing network architecture better than simpler solutions.
Warpgate
Fully transparent SSH, HTTPS, Kubernetes, MySQL and Postgres bastion/PAM that doesn't need additional client-side software.
Best fit: Teams needing centralised, audited access to internal infrastructure protocols without forcing developers to install proprietary client tools.
Worth knowing: As a critical infrastructure gateway, any downtime or misconfiguration immediately impacts all remote access paths to your systems.
MeshCentral
Run your own web server to remotely manage and control computers on a local network or anywhere on the internet.
Best fit: System administrators and IT support teams who require a dedicated, self-hosted solution for managing multiple remote endpoints without relying on third-party cloud services.
Worth knowing: Self-hosting a remote management infrastructure introduces significant security responsibilities, as any misconfiguration could expose managed endpoints to unauthorised access.
