# Relyo > Relyo (pronounced /rɪˈlaɪ.oʊ/, “ri-LAI-o”, from “rely”) is a free, open-source co-browsing tool for support: the user taps “Support” on a website or in a Flutter app and reads out a 6-digit code; the supporter enters it on relyo.de and sees the screen live, can point and draw and, after a second consent, take control. - Consent first: no screen data before the user agrees on their device; sensitive fields are masked on the device. - No recording: screen content is only sent live. - License: 0BSD. - Entering a support code is meant for humans; agents should read the docs. ## Pages - [Enter support code](https://relyo.de/en/index.md): Co-browsing for support: enter a code, see the screen live, point, draw and, with consent, take control.
