FAQ
What is the best open source alternative to TeamViewer?
The best choice depends on your workflow. Start with the tools compared on this page, then check hosting options, license, integrations, and whether the project covers the TeamViewer features you use most often.
Are open source alternatives always free?
Not always. Many projects publish open source code and offer a paid hosted plan, support, or enterprise features. Self-hosting can reduce vendor lock-in, but it may add infrastructure and maintenance work.
Should I self-host these tools?
Self-hosting is useful when data control, compliance, or customization matters. For small teams that prefer less maintenance, a hosted open source vendor can be a better first step.
