Good API, quick setup

I signed up for the free tier of the User-Agent Lookup API last week. The process was straightforward; my API access key landed in my inbox within a minute of signing up. I integrated it into a small personal project to detect browser types. The documentation was clear enough, and the JSON responses were easy to parse. It's been running smoothly, no unexpected issues so far. I haven't needed to contact support, which is always a good sign.

Super easy to use!

I needed a reliable Device Detection API for a new app and userstack delivered! Signing up was a breeze, and I got my API key instantly. The Real-time Device Intelligence is super fast. This is exactly what I needed for my project. I'll definitely be upgrading to a paid plan soon. Highly recommend it to other developers!

Works as advertised

Got the free plan for OS Detection API. Integration was simple. It correctly identified OS versions. No complaints.

Thinking of moving to Userstack for device detection, currently on a different provider. Anyone got experience with their OS detection accuracy?

D Deepak91 3 weeks ago ✓ Best Answer

I switched from another service a few months back. Userstack is definitely better with mobile device detection and tablet detection. We had issues before with differentiating between certain phone models and tablets, but it's much cleaner now.

D Deepak91 3 weeks ago

Agreed. It was a headache before.

R RahulK 3 weeks ago

That's a big plus. Mobile accuracy is crucial for us.

S Sneha22 3 weeks ago

Does it also do crawler detection well? We get a lot of bot traffic.

P PoojaR 3 weeks ago

It's pretty accurate for me, especially for common OS like Windows, macOS, Android, iOS. Haven't had any major complaints. Detects versions well too.

P PoojaR 3 weeks ago

Yeah, it handles the main ones well. Some of the niche stuff can be hit or miss but that's common.

R RahulK 3 weeks ago

Good to know. My current one struggles with some older Linux distros.

A AmitM 3 weeks ago

Not sure about OS detection specifically, but their bot detection is pretty solid. We use it mainly for that and it catches most of the unwanted traffic.

N NikhilS 3 weeks ago

Following this thread.

R RahulK 3 weeks ago

That's a different use case, but useful info, thanks.

Is userstack better than DeviceAtlas or WURFL? Looking for something reliable and accurate for device detection.

L Lisa Beaumont 1 month ago

Hard to say "better" universally, depends on your specific needs. I found userstack to be more straightforward to integrate and their free tier was a big plus for getting started compared to some others.

E Elena Osei 1 month ago

I've used both DeviceAtlas and userstack. Userstack's JSON output was way easier to parse for my setup. Accuracy seemed comparable for common devices though.

Thinking about the Enterprise plan, but worried about getting stuck if it's not a good fit. Can you cancel anytime?

K Kevin T. 1 month ago

Yeah, you can cancel whenever. I had to downgrade once and it was pretty painless.

M Megan F. 1 month ago

They're pretty chill about cancellations from what I remember from their docs. It's not like you're locked into a super long contract, even for higher tiers, afaik.

Are there any promo codes floating around for userstack? Trying to get a discount on an annual plan.

P Paula Hughes 1 month ago

Promo codes are super rare for userstack, honestly. Your best bet for a discount is usually just going with the annual billing option, that automatically gives you 20% off compared to monthly.

J Josh Okafor 1 month ago

I've never seen a real promo code for them outside of maybe Black Friday or something, but that's not even a guarantee. The 20% for annual is the standard deal.

My Userstack subscription is up for renewal soon. Anyone know if there are any renewal discounts or hidden promo codes floating around?

P PoojaR 6 hours ago ✓ Best Answer

I got a renewal discount last year, but I had to ask support directly. They didn't just offer it. Worth trying that route.

P PoojaR 6 hours ago

It was like 15% off the annual plan, which was pretty good considering I was going to renew anyway.

C coolboy88 5 hours ago

Good tip, I'll send them an email. Was it a decent discount?

A AmitM 9 hours ago

Haven't seen any specific renewal codes publicly. Most of their deals are for new customers or the annual upfront payment.

A AmitM 8 hours ago

Could be worth checking if you qualify for a startup discount if your company is new.

C coolboy88 7 hours ago

Makes sense. Thanks for the info.

R RahulK 6 hours ago

I think they sometimes have annual billing discounts, like 20% if you pay for the whole year upfront. Not sure if that counts as a 'renewal' discount though.

C coolboy88 5 hours ago

Yeah, the 20% annual billing is standard, I was hoping for something extra on top of that.

Thinking of signing up for one of the paid plans, but kinda want to test it out first. Is there like a free trial or something for the higher tiers?

A Alex Carter 1 month ago

Nah, not really a trial for the paid stuff specifically. They just have a pretty generous free tier that you can use forever.

C Cleo Q. 1 month ago

Yeah, what they said. The free plan is basically your trial for everything, just with lower limits. If that works for you, then the paid ones just scale up the usage.

Can I use both JSON and XML with this API, or is it one or the other?

K Kate Silva 1 month ago

Yeah, it supports both. You can specify which format you want the response in.

M Mia 1 month ago

Confirmed, you can get the data back in either JSON or XML. Super flexible for different dev environments.

Does userstack have something to block bots or detect those annoying crawlers? Need to clean up my traffic data.

R Rosa 1 month ago

Yep, they do! I use it for that exact reason. It's pretty good at spotting bots and crawlers, definitely helps filter things out.

M Megan Vargas 1 month ago

Pretty sure that's one of their main features. You can configure it to detect and flag those types of requests.
