Camsurf

CamSurf has been running since 2015 and reports more than twenty million sign-ups. It is a browser-based random video chat with a deliberately plain interface, and its pitch is simplicity: start, get matched, move on. What separates it from the other plain roulettes here is the country filter.

You select a country, choose whether you are male, female or a couple, confirm you are 18 or older, and start. The country selector is the useful part: it is the simplest way in this category to end up talking to someone from a specific place, which is what makes it a practical choice for language practice rather than general socialising.

Free, with no account and no download. CamSurf does not push a premium tier at the point of use the way several sites here do, and it runs a press and stories section, which suggests it is trying to be a publication as much as a chat service.

It requires an 18+ confirmation, publishes community guidelines, and provides a report tool for problems. The moderation detail published is thinner than Bazoocam's or Chatroulette's. The country filter is itself a mild safety feature: choosing a region narrows who can appear, though it does not narrow it to people you know.

Language learners above all. If your goal is to speak with native speakers of a particular language, a country filter is the most direct tool in this category and CamSurf makes it the centre of the experience.

Unfussy and useful. It does not compete on scale or moderation transparency, but the country filter plus a clean interface makes it the most practical choice for a specific, common goal.
