TeamViewer alternatives compared
ShellHub edges MeshCentral 93 to 86, and most of the difference is Docker support: a Docker image against no Docker image. MeshCentral has the largest following at 7.5k stars, yet ranks #2 of 4, held back mostly by Docker support (no Docker image).
The most recent release is ShellHub v0.28.0, published 2 days ago. Guacamole publishes no tagged releases, which costs up to 25 of the 100 points. None of the measured options scores under 40. By stack, Java (2), C (1) and Nodejs (1) are the most common. ShellHub, MeshCentral and Guacamole are permissively licensed. SparkView is source-available rather than open source, which limits commercial reuse. SparkView is not hosted on a forge Repoly can read, so it has no measured score yet.
