Thundr scores 28 out of 100 in ChatRadar’s testing, a Safety Tier D built on minimal moderation and no signup requirement. It’s free to use with a genuinely large global user base, and testing found gender and location filtering included free — a generous combination that comes with the lightest moderation level ChatRadar tracks.
What Thundr Actually Is
Thundr is a fast, minimal-UI roulette video chat platform: press Start, get matched instantly, press Next to cycle to someone new. It reports serving over 5 million users globally across multiple languages, and offers gender selection, location filtering, and facemask customization without a paywall in front of any of it.
Against most of our full ranking of all 49 platforms, Thundr’s free gender and location filtering is a real point of difference at this safety tier — several similarly scored competitors charge for exactly these controls, while Thundr includes both.
How It Works
- Go to Thundr’s site in any browser, or download the Android app.
- No registration is required — press Start to connect immediately.
- Select a gender preference and location filter if you want to narrow your matches.
- Get connected to a random stranger matching your filters.
- Press Next at any time to end the session and find someone new.
- Use facemask or nickname customization if you want, or skip straight to chatting.
What It Costs
Thundr is free, with no paid tier found during testing — gender selection, location filtering, and facemask features are all included rather than sold as upgrades.
That puts it alongside platforms with no cost at all in ChatRadar’s grid, with more free filtering than most competitors at this safety tier.
Safety
Thundr scores 28 out of 100 in ChatRadar’s testing, landing it in Safety Tier D, ChatRadar’s lowest tier. That reflects minimal moderation and no signup requirement, despite the platform’s generous free filtering.
See our scoring methodology for the eight dimensions behind that number, and ChatRadar’s Safety Index for how Thundr compares across all 58 platforms we track.
Who It’s For
Thundr fits someone who wants free gender and location filtering without paying for it, and who’s drawn to a large, genuinely global user base over a smaller or more curated platform.
It’s not for anyone prioritizing safety infrastructure over cost. With Tier D moderation and no signup step, Thundr offers fewer structural protections than platforms in higher tiers that charge for the same filters it gives away.
Where It Falls Short
The honest downside is the same trade-off shared by other generous-but-unmoderated platforms at this tier: free filtering is a real value, but Thundr’s Tier D score reflects minimal active review behind it, and no signup requirement removes any identity-based accountability.
How It Compares
| Platform | Safety Score | Free Tier | Signup Required | Native App |
|---|---|---|---|---|

| CooMeet | 93 (A) | Trial only | No to start | Yes |
| Camsurf | 75 (B) | Freemium | No | Yes |
| Chatingly | 28 (D) | Yes | No | No |
| Skibbel | 28 (D) | Yes | No | No |
