Trango review
A free, open-source calling app for small groups, with self-hosting and a four-person call limit.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Trango is a free, open-source calling and file-sharing solution for small groups that want encrypted communications and the option to run a self-hosted web app. It supports one-to-one audio and video calls, group audio and video calls for up to four people, and file transfers. Its local-network calling can work without internet access, which makes it relevant to groups whose needs center on calls within a local network rather than broad platform coverage.
The self-hosted option is a key distinction: Trango includes a web app and discovery server for self-hosted deployment, alongside cloud deployment. The project describes calls and file sharing over both local networks and the internet. This combination may suit technically capable small groups that want control over deployment and value local-network operation. Trango is also open source and free, so its stated offering does not depend on choosing among paid tiers.
The main trade-offs are scale and maturity. Group calls stop at four people, making Trango a poor fit for larger meetings. The project labels the software beta, so buyers who need a mature calling product should weigh that status before choosing it. Its listed platforms are web and self-hosted; organizations looking for a broad set of established client options may prefer an alternative. Choose Trango for small, encrypted calls and file transfers where local-network use or self-hosting matters more than larger groups; look elsewhere if call size or platform breadth is central.
