All industry incidentsWe found no public reports of hacks, leaks, or funds stolen through Nstbrowser. This is not a guarantee: we check public sources, not the service’s code.
We count breaches and leaks on the service’s side, attacks through updates and extensions, account takeovers, and hacking attempts reported by the company itself. Brand impersonation, unverified complaints, patched vulnerabilities that were not exploited, DDoS attacks without data leaks, and account bans by platforms are not included in the incident count; they appear in the “Worth knowing” section.

They don't help, and the service is crap with a lot of bugs. Don't use it, you risk getting your accounts banned.
I've used the free tier for months and it works the way any commercial anti-detect browser should. I keep several YouTube accounts in it to get past YouTube's anti-bot measures and download videos with python + ytdlp. What I value most is that the API is available on the free and pay-as-you-go plans. Logging into the desktop app sometimes hiccups on browser verification, but the FAQ/known issues guide was enough to fix it without contacting support, and the dev is active with an active Discord.
It has a good free limit, a modern interface, a lot of features and a good API. It's a bit expensive without their frequent discounts. I use it to test and use websites from multiple locations without switching the time or turning on a VPN every time.
Not worth it. The browser wouldn't open even after I uninstalled and reinstalled it. When I tried to reach customer support, they told me I had to contact them through Discord and no other channel if I wanted a response.
I bought a 1GB premium proxy pack, and NST browser burned through it fast: I only visited 3-4 IP-check sites and 100 MB was gone before I even started warming up or collecting cookies. The geolocation page alone used 20 MB in under 10 seconds. I'm going to try a different browser.
NST browser is the best I've seen so far: lots of options and utilities for smooth browsing at little cost. On the free plan I can only create 10 profiles per day, but paying as you go costs little compared with most browsers I've seen. Kudos to the NST team.
It's sad how they removed the free plan without any prior notice. My usage stayed the same, but the price went from free to roughly what more established antidetect browsers charge. They could have removed it only for new or unregistered buyers, or given us a grace period of 2 weeks or a month, or a small credit as compensation. If I'm going to pay about the same as for another antidetect browser, having 100 concurrent browsers is much better than 100 browser launches.
The free plan went from 1000 to 10 profile launches a day, plus a 10-hour browser limit. At 100 launches a day that is $30 a month, realistically $60, and for that price there are lots of alternatives. A month later I only need 25 profiles and pay around 5.5$ for the whole month (10 free and 15 paid launches daily). What's really annoying is that about 2 times a month I get forcefully logged out and all my browsers close with no notice or warning.
The free plan was gone without a word. I only use about 40 profiles, and suddenly I got an email saying my balance was insufficient and had gone negative. They didn't even warn us that the free plan limit would be cut, just sent an email that my balance was negative.

My experience with NST Browser has been positive so far. The free version is enough to try all the core features, and the free API key is a big plus if you want to automate tasks without upgrading right away. It's easy to set up, stable and has solid fingerprint management. The only downside is the limit of 30 profile launches on the free plan, so larger operations will need a premium plan.
